More and more advertisements are introducing 4G, people declaring a new era is coming. As a consumer, maybe you can't concern what is or what is 4G LTE, the top thing you want to know is what I can benefit from 4G. Great, that's the key point. What can we benefit from 4G?


To explain simply based on real life experience, you can download an HD movie of 2 GB or more in a few seconds, you can play complex online games without interruption, and you can transfer large files in a very short time. Yes, 4G can give us fantastic speed! That's why the providers are trying to promote 4G, they finally want you guys to use their 4G devices. Of course, most of the time, there would be contract with the devices and you cannot freely use any other SIM card.

But if you have unlocked broadband and SIM unlocked for all operators, how do you choose the right model per preference? Since the most popular device from 4G operators is 4G USB modem with LTE technology, so let's take 4G LTE USB modem as an example to explain, of course, unlocked. Then our question are change: How to choose a 4G LTE USB modem?


Actually, to buy a 4G USB modem, just like buying a cell phone. Most people would consider the brand, Apple, Samsung, HTC are known and series of phones are optional for almost all preferences. And it's not difficult to pinpoint. But for 4G USB modems, it doesn't seem that simple ... It's probably because most of the equipment suppliers are not as famous as the provider and the second reason is that the modems, routers, or other telecommunications equipment have the provider's logos printed on them. Take Vodafone Surfstick K5005 4G LTE as an example, even if the users have been using the surfstick for many years, they may not know it is from HUAWEI and the HUAWEI factory model is HUAWEI E398.


So the first step to choosing a 4G USB modem is to find which brand you prefer. If you don't know, it would be better to make a decision. Follow me, I will guide you. Someone may ask, may I know how many brands are there around the world? Ok, it's time to share, most of us can know SAMSUNG smartphone, but actually SAMSUNG is also professional in network solution. So there are also 4G USB modems available in the market. Some guys feel good, ok, I like SAMSUNG, I choose it. You will be glad not so early. After reading the whole article, you may feel disappointed. Well I could tell you, Samsung 4G LTE Surfstick is only for certain countries and LTE frequency, so it may not be suitable for you. And the top brands of 4G USB modems are Huawei and ZTE in China, Novatel Wireless and Sierra Wireless in the US, has an option in the US, Alcatel-Lucent, Motorola, LG in Korea is also 4G USB modem Pantech also well known in USA.


At that time, you may feel tired, oh my god, so many choices, hard to choose. Yes, it's just like that, follow the SIM card provider and find the unlocked model in the market. Take Telstra 4G LTE AirCard 320U (manufactured by Sierra Wireless), for example, if you like it and do not want to use it with a contract, an unlocked online store can be found here. Then you are satisfied.


The premise is that you know this model number, but if you don't know the model number how to proceed?

So if you don't know the make and the provider model, you can follow these steps to determine:

First confirm your local 4G LTE frequency band, if you don't know please refer to the two links below:

A.) List_of_LTE_networks: (see LTE bands)

B.) 4G card: (see LTE network bands and status)

(Note: most of the information from the two links is on the right, but not all of it)

After the confirmation, you need to make sure that the local 4g LTE network is already started for trading. If not, there is no 4G network available there.

Choose the correct 4G USB modem that would work for this band. Here we have an option for you: 4G Mobile Broadband Shopping Center (

To make it clear, here is another example to explain. Assuming you live in Sweden, after the check, we found the LTE frequency bands as follows:

Band 7 (2600 MHz) from Telenor / Tele2 / Net4Mobility / TeliaSonera Ready

Band 20 (800 MHz) from TeliaSonera Ready

Band 8 (900 MHz) from Telenor / Tele2 / Net4Mobility Ready

So you can choose any 4G USB modem that can work for LTE FDD 2600MHz. And to use TeliaSonera, the modem must support 800 MHz, if not support 2600MHz. As of this point, you can find that Samsung 4G LTE Surfstick has two names GT-B3730 and GT-B3740. GT- B3730 works on 4G and 3G FDD 2600MHz 2100Mhz,

while GT-B3740 only works on 4G FDD 800Mhz, no 3G. So if you want Samsung, you can check whether the two 4G modems are working in your country.


You can check out there are many models on 4G Mobile Broadband Shopping Mall that can work for this band, like ZTE MF820, HUAWEI E392, E398, Sierra Wireless 320U etc ...

GT- B3730 works on 4G and 3G FDD 2600MHz 2100Mhz.


And please confirm the the band LTE-TDD or FDD, because it can be TDD 2600MHz. It is special band for TD-LTE network, FDD 2600MHz modem cannot work on this.

It is clear now. But if your 4G network is WiMax, there are now a few options. We encourage you to follow your provider now, maybe in the near future, you can follow my method to choose what you like. Good luck.
