With the ZTE MF821D, you receive a flexible surf stick that supports both LTE and all other major mobile communication standards, such as UMTS and HSPA+. O2 4G USB is therefore compatible with 2G, 3G and 4G networks. LTE can be received via the usual bands 3/7/20 (800/1800MHz/2600MHz). O2 uses LTE 800MHz for priority; the 4G network of LTE Band 7 (2600MHz) will be available in the cities in near future. The theoretical maximum download speed of 100Mbit/s and 50 Mbps upstream speed could be achieved. Currently, however, O2 offers “only” tariffs of up to 50 Mbps.

 

 

 

 

ZTE MF821D can work as the same as the data stick. The internal slot can hold MicroSD card up to 32 gigabytes. You can buy them from 4gltemall.com with the stick MF821D. The stick MF821D is perfect for mobile use on a laptop or notebook, and of course it can also be used at home on the desktop. It’s advisable that under certain circumstances, the data transmission rates vary depending on the local reception conditions. According to ZTE introduction, the MF821D stick is compatible with the Windows operating system with XP, ServicePack3, Vista SP2 or Windows 7, and Mac OS Version 10.5 is also supported.

 

At just 47 grams and the dimensions of 87.3 × 29.5 × 14 mm, you will hardly notice the MF821D in your pocket. The actual USB plug can be incidentally folded and thus saves space and it can also facilitates the connection as a “arm” for the laptop.

How to Buy 4G Modem between Similar Models?

More and more people are choosing 4G modems as their preferred network in the plan. And more and more 4G dongles are available for various operators all over the world. Then here comes a problem: many customers feel confused by the models and especially two similar models. Customer don’t know what’s the difference, which make s them in trouble deciding which one to buy.

 

 

ZTE MF821 and MF821D are two similar 4G dongles. We will take the two 4G LTE modem as example to explain our topic today. Now if I list them in front of you and let you tell what the difference is. You maybe feel headache…don’t worry; if I were you, I also can’t tell anything, perhaps my answer is they are completely the same.  But actually, they are different, of course, not on the appearance.

 

The key differences for most of the 4G modems are the LTE frequency bands that they could support. Other features are almost the same and not influence the usage. ZTE MF821 could support 4G LTE band 1, band 3 and band 7 (1800/2100/2600MHz). But ZTE MF821D supports band 3, Band 7 and band 20(800/1800/2600MHz).

 

Even though some customer may concern about the connector for external 4G antenna, the network bands should be the first concern because it determines whether a 4G modem would work properly or not. And we could see this feature from the dongle body. The inner part, especially the technical specifications are invisible.

 

 

Getting to know the specification of the 4G LTE modem, user need check the operator’s network bands. If the bands are partially the same as the 4G USB dongle or 4G mobile hotspot, then the operators’ SIM card work with the Wireless devices.  But if you are using a USB modem that is not with contract plan, you must make sure the USB modems are SIM card unlocked.

 

 

Above should be the key matters that influence the usage of a 4G dongle/modem/surfstick/datacard.  If you want to know the details of a 4G USB Modem, welcome to check the list UEs by LTE Frequency bands: http://www.4gltemall.com/ue-by-spectrum.html
