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

HUAWEI E392u-12---- The Most Popular Surfstick of HUAWEI E392 4G USB Modem

As the flagship of 4G LTE USB Modem, HUAWEI E392 4G LTE Multimode USB Modem like a big tree, derives many branch models, such as HUAWEI E392u-12, HUAWEI E392u-21, HUAWEI E392u-22, HUAWEI E392u-92, HUAWEI E392u-6, HUAWEI E392u-9, HUAWEI E392u-511 etc… They are for different operators in different areas, so they incorporates difference modules to support various 4G LTE bands.

[/caption] Based on good quality and reliable performance, HUAWEI E392 4G LTE Modem is the first option for many network providers. Which one is the most popular model?

 

Before we give the conclusion, let us talk about the 4G network deployment status. From the beginning of 2012, operators all over the world are planning and starting deploying the 4g networks. At this trend, the providers in Asia seems running faster than European operators. Perhaps it’s due to the economic depression in European area.

 

Per the report of 4G network status, LTE technology is most commonly adopted to use in data transmission. And the LTE Band 1800Mhz is most commonly deployed spectrum, 38% current LTE networks choose 1800Mhz (Band 3). It’s the refarming of GSM 1800Mhz. As we know, GSM is the most common 2G network. And per our information, Band 7(2600Mhz) is also the common FDD network in Europe and APEC areas. Then we look back to HUAWEI E392. The brand model works on band 3 and band 7 has two models HUAWEI 392u-12 and E392u-6.

HUAWEI E392U-12 4G Modem support LTE FDD 800/1800/2600 Mhz while HUAWEI E392U-6 4G Surfstick supports LTE FDD 900/1800/2100/2600Mhz. Band 1(2100MHz) is only available at North Amerian and Band 8 ( 900 Mhz) only deployed in few countries. But 800Mhz is a common LTE spectrum in Europe and Asia.

If you are a professional journalist or other professional who usually travel between countries and need fast data transmission, it’s necessary to take HUAWEI E392u-12 around. Frankly speaking, comparing with 3G USB modem, HUAWEI E392 seems a little large, but compare with digital camera and luggage carrier, it’s slim enough. 4GLTEmall.com could offer unlocked one.
