Unlocked Telstra USB 4G (ZTE MF821) 4G USB Modem Review

Today, we get a new 4G LTE USB datacard, the 4G aircard model number is ZTE MF821. The 4G modem is packed well in a box, there is the operator’s logo “Telstra USB 4G” on the front box, and the information is telling user this 4G USB modem. The ZTE MF821 is already unlocked by our group, so users don’t need worry about the lock issue.

 

 

At the side of the box, we can see that LTE Frequency bands that ZTE MF821 could work with. The specification indicates MF821 could support FDD LTE 1800/2600Mhz, but per our information from the manufacturer ZTE, the modem MF821 4G aircard could support band 1, band 3 and band 7(1800/2100/2600MHz), we suppose this band is not activated because the operator Telstra is not providing the LTE band 1 (2100MHz).

 

 

 

And the 3G DC-HSPA+ Tri-band (850/1900/2100) is backward compatible. Under the 4G LTE network, user could enjoy high speed up to 10Mbps. Even on 3G network, ZTE MF821 could reach speed to 42Mbps.

 

 

 

Open the package, we can see the 4G dongle ZTE MF821. There is a logo of “4G” and “T”, which means Telstra 4G. On the side, we can see two small icon of signal; they are two hidden connectors for external antennas. This feature is important for 4G data transmission, and it lets MF821 different from MF820 or MF820T. On the other side, there is no slot.

 

 

 

The USB of ZTE MF821 is rotatable for 180 degree, user could hide the USB in the body of MF821. User need open the back over and find the SIM card slot. On the SIM slot, we can see the model number, IMEI number, place of origin (Made in China) and manufacturer ZTE Corporation. And close to the SIM card slot, there is a slot for MicroSD memory card. The MF821 could support maximum 32GB SD memory card.

 

 

 

Comparing with other ZTE 4G Aircard, such MF880 or MF820D, ZTE MF821 is really very slim, the size of MF821 is as big as a 3G datacard.  So if a user prefer a small size USB dongle, ZTE MF821 is a good option and without any contract. But before purchase, user should concern about the 4G frequency band  compatibility, if you want a 4G Aircard for FDD band 20 (800MHz) or TDD band 38 (2300MHz), or any other bands that are not same as MF821 supporting, you may need check other model and choose the right one. You can check here more 4G Aircard for various LTE frequency bands:   http://www.4gltemall.com/ue-by-spectrum.html

 

 

 

 

 

 

ZTE MF28G 4G LTE Router VS ZTE MF28D 4G LTE CPE

As the one of the most important UE device to support 4G LTE networks, 4G Router is on a replaceable position. Many vendors are trying their best to improve the research and development on this field. The Chinese vendor ZTE is also trying to present more telecommunication equipments to share the market.

 

As we can see, just ZTE 4G Modems, ZTE 4G Routers also looks very similar in appearance. Perhaps they just want to save more budgets, just using one appearance design and change the inner core part to make up a new model. So users usually can’t identify which model number of a LTE router, even when they know two model numbers of the router, they don’t know what the difference between them is. ZTE MF28G and MF28D are just on the case.

 

ZTE MF28G and MF28D are the 4G LTE CPE/Router from ZTE, they are for the 4G LTE networks and provide high speed Internet connection.

 

 

Appearance

 

As we said, they are using same appearance design, from the outside, we can’t tell from them. There are almost same indicators on the front screen, on the back, there are 4 RJ45 Ethernet cable ports, 2 RJ11 connector for analog telephone and one USB 2.0 interface for host file sharing.  And beside is the plug port for power supply.

 

 

Network Frequency Bands

 

 

The frequency bands supported should be the key difference between the two 4G Routers. ZTE MF28D router is a FDD-LTE router, which support 4G FDD band 1, band 3, band 7 and band 20 (800/1800/2100/2600MHz). And 3G DC-HSPA+/UMTS networks (900/1200MHz) are backward compatible.

 

 

ZTE MF28G LTE CPE is a FDD/TD-LTE dual-mode CPE router. MF28G Router could support FDD band 7 band 20(800/2600MHz), and TD-LTE band 38 & band 40 (2300/2600MHz). Similarly, ZTE MF28G LTE router also could support 3G networks as backup.

 

 

Connection Speed and User Support

 

In good network environment, the peak download speed of ZTE MF28D could reach 100Mbps and upload speed to 50Mbps when work on FDD networks. The speed ZTE MF28G varies depending on the network mode. When working on TDD mode, MF28G could allow maximum download speed up to 68Mbps and upload speed up to 17Mbps. However, if working on FDD LTE networks, the downlink could reach 100Mbps and uplink could reach 50Mbps.

 

 

Of course, the speeds above for data rate speed are theoretical and can make true only in preface situation. In real life, the speeds may not as faster as expected, but it’s still amazing and much faster than 3G speed.

 

ZTE MF28G and MF28D could both allow up to 32 users to get connected and surf. So they are good for SOHO, home and small office. The USB interface is help group users to share the files via host Memory.

 

If you like them, you could buy them from www.4gltemall.com , and before you buy, please confirm the 4G network status and choose the right one. If you need any help, we will be always available here.

 

Difference Between ZTE MF93E and ZTE MF91D 4G LTE Mobile Hotspot Router

Following the commonly deployment of 4G LTE network worldwide, more and more 4G terminals are demanded by the operators. As one of the important vendors, ZTE had gained many business plans from the operators and its wireless gadgets are also very popular. ZTE MF93E and ZTE MF91D 4G LTE mobile hotspot are two models for 4G LTE networks.

 

 

Sometimes, most customers may know the model number of the UEs. But they don’t know whether the 4G modems or 4G routers would work with the providers in their countries. Today, we will have a review of the two models ZTE MF93E and ZTE MF91D.

 

Network Frequency Band

 

ZTE MF91D 4G Hotspot is earlier available in same countries, it’s mainly European 4G networks. MF91D Hotspot supports 4G FDD band 7, band 8 and band 3 (900/1800/2600MHz); they are the most popular three spectrum band in European area. And the 3G UMTS & 2G networks are backward compatible.

 

 

 

 

 

 

ZTE MF93E 4G Mobile Router is a LTE dual-mode (TDD & FDD) WiFi Hotspot. It supports TD-LTE band 3 & band 7 (1800/2600MHz) and FDD bands 38 & band 40 (2300/2600MHz). Based on this specification, MF93E hotspot router is more suitable for the 4G networks in Asia and Middle East areas, such as Hong Kong, Saudi Arabia, Kuwait, China etc.. Just like MF91D, ZTE MF93E dual-mode TDD/FDD hotspot could also works on 3G UMTS 900/2100MHz and 2G GSM/GPRS networks.

 

 

Appearance

 

The appearance of ZTE MF93E and MF91D looks not the same. MF93E is in the design of horizontal, but MF91D is in vertical design. To make the device more user-friendly, the both have only one button in the front. And there is OLED screen to indicate the important information, including network status, operator, WiFi connectors, battery life and data statistics. The batteries in the body are removable and re-chargeable.

 

 

 

Link Speed and Connectors Support

 

 

ZTE MF91D 4G Pocket Router could reach peak download speed up to 100Mbps and upload speed to 50Mbps on 4G LTE FDD network. It could allow up to 10 users access Internet simultaneous. ZTE MF93E has the same functions like MF91D when it’s on FDD mode, however, when working on TD-LTE network, MF93E could support maximum download speed up to 68Mbps and 17Mbps for upload.

 

 

 

Above are the important features of the 4G Pocket WiFi that matters the user experience, if you want to buy unlocked ZTE MF93E or MF91D, welcome to land www.4gltemall.com .

 

 

 

 

ZTE MF28B Rogers LTE Rocket Hub VS ZTE MF28G 4G LTE Router

As one of the main 4G LTE telecommunication equipment vendor, ZTE has presented many 4G LTE router to public, and most of them are already for operators’ contract plan. Unlike Huawei B593 4G LTE CPE many modification models, each of ZTE 4G LTE routers has specific modem name, even though they look almost same in appearance.

 

 

 

ZTE 4G LTE routers are designed in same appearance model, but they are not completely the same in some aspects.  Today, we will have a review of the difference between ZTE MF28B and MF28G 4G LTE Router.

 

 

Network Bands

 

Most of the routers with appearance differ on the network bands. They are for different operators. ZTE MF28B Router is for Canadian operator Rogers, and it’s also called Rogers LTE Rocket Hub, but MF28B Hub could support single LTE band 7 (2600MHz), 3G HSPA (850/1900MHz) network is backward. As we can, it mainly for 3G network in North America.

 

 

ZTE MF28G LTE Router is more powerful, it supports LTE dual-mode (TDD & FDD), it could support 4G TDD band 38 & band 40 (2300/2600MHz) and FDD band 7 & band 20 (800/2600). And ZTE MF28G supports 3G UMTS 900/2100MHz. ZTE MF880 4G LTE USB dongle could support these bands.

 

So unlocked ZTE MF28G could work with more 4G operators and in some countries, MF28G could replace MF28B.

 

 

Data Rate Speed

 

 

ZTE MF28B and MF28G could both reach peak downlink speed up to 100Mbps and uplink speed to 50Mbps on 4G FDD network. Simultaneously, MF28G could reach peak downlink up to 68Mbps and uplink speed to 17Mbps when working on TDD networks.

 

 

Interfaces

 

 

There are some adjustments in the bodies of the two ZTE LTE routers. MF28B has only 4 Ethernet ports (RJ45) while MF28G has 4 Ethernet. Ports, 2 RJ11 ports for telephone, and one USB 2.0 host port. So MF28G could support telephone and SD files sharing, but MF28B cannot.

 

 

Logo

 

 

Sometimes, the logo on the router may vary according to operators. And the firmware may also be customized for operators. As we can see, the Rogers LTE Hub ZTE MF28B has Rogers’s logo on it and the forms are version is also with Rogers logo.

 

 

 

Other features of the routers are almost the same, to conclude, Unlocked ZTE MF28G is powerful when roaming globally. In certain countries, MF28B may be reliable on 3G networks.

 

What’s the difference between HUAWEI B593s-22 and B593u-12?

Here now, we get to know there is a new model available now for HUAWEI 4G LTE CPE Router B593, the model number is HUAWEI B593s-22, its appearance is almost same as other HUAWEI B593 sub-models, such as HUAWEI B593s-82, B593u-12, B593s-58, B593s-58b, but there is really some difference between these models.

Let us talk first the difference between HUAWEI B593u-12 and B593s-22:

From the above image, we could see that HUAWEI B593s-22 supports more 4G LTE bands, not only support FDD Band 800/900/1800/2100/2600MHz, but also TDD 2600MHz, while B593u-12 supports only FDD bands.

Secondly, the downlink speed of HUAWEI B593s-22 could reach up to 150Mbps while B593u-12 supports 100Mbps. So HUAWEI B593s-22 is actually a LTE Category 4 CPE Router, like HUAWEI E5172 4G LTE CPE.

Thirdly, the interface in the device is different, HUAWEI B593s-22 has only one USB interface in the device while B593u-12 has two. other features are the same. Other B593 Router sub-models have same appearance as B593u-12, just frequency bands are different.

So HUAWEI B593s-22 is a 4G LTE Category 4 Router even with same appearance like B593 other models. It’s a dual-mode LTE Router for TDD/FDD modes.

Unlocked Rogers LTE Aircard 330U from Sierra Wireless General Review

You may had seen a 4G LTE Modem which support 4G Band 4(1700/2100MHz) or 4G LTE Surfstick which is for 4G FDD Band 7 (2600MHz), but do you know any 4G USB modem that could support them together?

Today, we will recommend a 4G Aircard which could support the 4G LTE FDD Band 4 and Band 7 simultaneously. The model number is Rogers AirCard 330u LTE Rocket Stick. This is the successor of Sierra Wireless AirCard 320u. They are both from Sierra Wireless. The difference between them is that Aircard 330U is capable of LTE FDD Band 7 and Band 4, but AirCard 320U could support band 3 and band 7.

 

The Rogers LTE AirCard 330u looks cool in red color, but it’s unlocked to Rogers network. It means the AirCard 330u could support any operators’ SIM card.

 

 

Just like the brother model AirCard 320u, 330u is in square shape and it’s bigger than AirCard 306 or 308. The USB could rotate for 180 degree. On the front, There is logo of Rogers and one the back, there is printer of “4G LTE” on it. Below the “4G LTE”, we can see the icon of the manufacturer “Sierra Wireless” logo, and the indicator of data transmission.

 

 

Open the back cover, we could see there is a stick indicating the model number “AirCard 330u” and the IMEI number of the 330u. Belie the stick, we can see the SIM card slot and MircroSD card slot. At the side of the SIM card slot, there are two external antenna connectors for MIMO. They are covered by two small cap, user need open the cap and then connect the external antenna.

 

The connector of the external antenna is TS-9 model, so if you want buy external antenna for AirCard, you could check here: http://www.4gltemall.com/external-antenna-for-huawei-4g-lte-usb-modem.html

 

 

After plug the two external antennas, the data link speed would improve obviously. The AirCard 330u is apt for North America 4G LTE networks band 13 and band 7, so it could also roam in Europe or Asia. In conclusion, AirCard is a cool USB modem that will be a good gadget for 4G networks.

Difference between Samsung GT-B3740 and GT-B3730

Samsung is always leading the trend of networking development. As the partner model of Samsung GT-B3740, the 4G LTE Surfstick Samsung GT-B3730 is not as popular as GT-B3740. Samsung GT-B3730 4G Modem is the company’s first USB-based internet stick from TeliaSonera that offers 4G networks connectivity as well as a backup plan.

 

 

 

Samsung GT-B3740 could support maximum download speed up to 100Mbps download speed and 50mbps upload speed. Samsung GT-B3730 could also do that, the difference between them is Samsung GT-B3740 could work only on 4G LTE FDD 800MHz while Samsung GT-B3730 could only work on 4G LTE FDD 2600MHz. So Samsung GT-B3740 could only work specific areas in Europe, because not all the countries in Europe deployed the band 800MHz. And GT-B3730 is also the same; it has to work conditionally on only LTE FDD 2600MHz.

 

 

 

Samsung GT-B3730 seems more powerful in application because it could not only work with 4G network, it could also work on 3G UMTS 2100MHz and 2G GSM/GPRS/EDGE networks. So if there is unlocked Samsung GT-B3730, users could use in every countries in Europe. Under 3G network, Samsung GT-B3730 could support maximum download speed up to 17Mbps and upload speed up to 5.76Mbps.

 

 

Samsung GT-B3740 and GT-B3730 both have dual external antenna connector, with external antenna, users could get more stable network connection and better signal strength, but we didn’t get any official information for the connector type.

 

Samsung GT-B3740 is in compact USB design but GT-B3730 is in rotatable USB design. GT-B3740 is used for Vodafone 4G LTE networks in Germany, but GT-B3730 is for Sweden operator TeliaSonera. TeliaSonera has nationwide 4G licenses in Norway, Sweden, Finland and Denmark. So if you don’t have specific requirement, Samsung GT-3730 is good for personal use.

Huawei E5776 4G LTE Cat4 Mobile WiFi Hotspot Test

A mini router is a small device that connects to the mobile network available, whether 2G, 3G or 4G, and forwards the connection via regular wireless networks (WiFi / WLAN). Min router is running on battery power, and it is an excellent solution for the person on the go and need network access everywhere on multiple devices – without the need for separate mobile subscription and receiver for each unit.

 

Previously, we tested the solution with 4G mini router from HUAWEI, the model number is HUAWEI E589. It offers highest 4G speeds up to 100 Mbps. But there is a new alternative mini router now: HUAWEI E5776 4G LTE Cat4 Mobile WiFi Hotspot

Huawei Mobile WiFi E5776

The two mini routers have many common features. The size is approximately the same, and they are both in small size, but thicker than a smartphone. There is one button operation and a small display that shows the status of the connection, battery level, and how much data is used since the last time you turned on the mini router.

Both of them could support battery charging via a micro-USB and there is slot for microSD cards.

 

But Huawei E5776 supports download speeds of up to 150 Mbps, and can handle up to ten WiFi users or devices simultaneously. Juar like HUAWEI E589, Huawei E5776 router also has a fixed battery of 3000 mAh. Both provide a service life of up to 6 hours. Huawei E5776 also has an app for iOS where you can see consumption, battery life, manage data on micro SD card and change the settings.

 

Installation

Our sample came without a SIM card, so we tested with the same SIM card that came from the operator Telenor. To get started you need to connect the router to a PC using the USB cable. The driver is installed automatically, and a configuration program is in the flash memory of the router.  Here are the icons of HUAWEI E5776 web management pages:

Home page

 

WLAN Basic Settings

 

SD Card sharing page

Then you just have to log on as the router and use the 4G network or other wireless networks that may be available.

Performance

In use on Telenor’s network, performance and coverage of HUAWEI E5776 were measured in the same way as HUAWEI E589 4G LTE Mobile WiFi. The Limitations corresponding with the date rates are not in hardware but in the infrastructure and provider limitations. However, we could reach only speeds of 35 Mbps down and 30 Mbps up, even though, it is not something to complain about. This was the fastest we measure. Taking the subway the other hand, or move into the city, or deep in office buildings covering an entire city block, the rate drops noticeably. Sometimes we lose 4G and may even have to make do with 2G connection (also known as “Edge”). The same results happened throughout the country, when you are in sparsely populated areas.

iOS App

If you have iPhone or iPad, you can also download a free app from Huawei. This allows you to check status, data usage, battery status and change settings.

 

The app controls most.

The memory card can store photos, music or video that will be available to all users on the network. If you have a 32 GB memory card, you can store a lot of entertainment when the family at the cottage or on a trip, without having to depend on the services of the mobile network. Alternatively, there is space capacity for many presentations and other data if the HUAWEI E5776 is for work usage.

Conclusion

This mini router HUAWEI E5776 is an excellent solution, and it works on all mobile networks and mobile network solutions. You can also buy it separately, so you can choose the service itself. , we reiterate our recommendation: That a mini router provides a great improvement in your browsing experience compared to 3G when move on the surface of a city with developed 4G network, there is no doubt. While Huawei E5776 LTE Cat4 Mobile WiFi works great as a single router in a household with one person, but there is more to talk for share. Data quota may soon be empty if you are an active user.

Huawei E398S-81 4G LTE FDD TDD USB Surfstick Review

Comparing with Huawei E398 other branch models, such as Huawei E398u-1, E398u-18 and E398u-15, Huawei E398s-81 should be a special one, it’s not because Huawei E398s-81 has different appearance as other models, it’s due to Huawei E398s-81 supports the TDD & FDD LTE band simultaneously, which covers the 4G LTE TDD 2300/2600MHz and FDD 2600MHz.

 

 

As the one of the most frequency bands for TDD, band 38 (2600MHz) and band 40 (2300Mhz) are invested by many operators who are planning or already launched TDD networks.

 

 

Today, we get the Huawei E398s-81 4G LTE TDD FDD Surf stick with HUAWEI logo on it. It seems that it’s SIM card free and unlocked to any operators. Usually, if there is an operator’s logo on HUAWEI E398 modem, it may be a locked one, but the modem could be unlocked by some methods.

 

From the appearance, we could see that HUAWEI E398s-81 is just like other E398 branch models, with the rotatable USB design. There is only HUAWEI 4G on the USB. No other logo was printed on the back.

 

 

As previously mentioned, Huawei E398s-81 could support the LTE bands/Spectrum above: 4G LTE FDD 2600MHz and TDD 2300/2600MHz. This should be the most important difference between HUAWEI E398u-1, E398u-15 and E398u-18.

 

 

With same appearance of E398u-11 and E398u-15, Huawei E398s-81 has two external antenna connectors beside the two sides of Micro SD slot. If user wants to use data card with MIMO technology, HUAWEI E398s-81 is a good option optional. Here now, only few models of 4G LTE USB Surfstick are available on the market for both TDD and FDD networks. HUAWEI E398s-81 should be a good one based on HUAWEI prestige.

 

 

Unlike other E398 Modems, Huawei E398s-81 could not work with 3G UMTS network or 2G GSM/GPRS network. So Huawei E398S-81 could only work on 4G LTE networks. If 4G networks are not available in certain place, HUAWEI E398s-81 can’t work. So users may consider this before they buy it.

 

 

 

As the brother model, Huawei E392 4G FDD TDD multi-mode data card also has one similar model, the model number is Huawei E392u-92. HUAWEI E392u-92 supports 4G TDD 2300/2600 Mhz, but HUAWEI E392u-92 can’t support 4G FDD networks.

 

If you want know more details of them, welcome to buy it from www.4gltemall.com .

 

 

What’s the difference between ZTE MF880 and ZTE MF820S2?

As one of the 4G LTE modems from ZTE, the TDD modem ZTE MF820s2 may not be well known because it’s born for China Mobile 4G LTE networks. ZTE MF820s2 looks very similar to ZTE MF820, they are using the same appearance module, but inner parts are completely different. ZTE MF820 is for FDD network while MF820s2 works for TDD & FDD.

 

 

There is another 4G TD-LTE modem ZTE MF880, which is also FDD compatible. Today, we will have a look at what’s the difference between ZTE MF820s2 and MF880.

 

 

Frequency Bands

 

 

Frequency band should be the key difference between similar 4G modems, even though some modems looks almost the same. The frequency band decides where could work or not, and which operators they could support. ZTE MF820s2 supports FDD 2600MHZ and TDD 1900/2300/2600MHz. The band 1900MHz is a special band that very operator has chose as their 4G network spectrum. So many other 4G modems could replace ZTE MF820s2 if the band 1900MHz is not a must frequency. ZTE MF880 could also support TDD 2300/2600 MHz, but it cannot work with band 1900MHz. As a TDD and FDD surfstick, ZTE MF880 also supports FDD800/2600MHz. So when users don’t require modem to support 1900Mhz, ZTE MF880 could fully replace MF820s2.

 

 

4G LTE Speed

 

 

As standard 4G USB modems, ZTE MF880 and MF820s2 both supports the TDD and FDD network. However, under the two technologies, the data transmission rates are different. When working on FDD network, the peak download speed could reach 100Mbps while upload speed up to 50Mbps. But if on TDD networks, maximum download speed could reach 68Mbps and upload speed could reach 17Mbps. By the way, the speeds are only theoretical speeds. In real practice, the network can’t be perfect as we wish; the link speeds may vary time to time.

 

 

 

External Antenna and MicroSD card

 

It’s a pity that both ZTE MF880 and MF820s2 both don’s have connector for external antenna. And we didn’t find any place to plug the MicroSD card. So they couldn’t use as flash memory card.

 

 

 

USB Design

 

ZTE MF880 and MF820 are both under design of 2D USB design. The USB is rotatable for 270 degrees. This design will help users to use more space when plug to PC.

 

 

We can’t make conclusion that which is better. They are in same brand and could meet different requirements from users or operators. So it would be better to know more about the difference between similar models. If you want to check more 4G LTE modems, welcome to land www.4gltemall.com
