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 .

Difference between HUAWEI E3251 and Vodafone K4605

Huawei E3251 DC-HSPA+ USB Stick is the new 42mbps USB dongle in 2012 from Huawei, it is the upgraded model from Huawei E372 3G USB Stick. Today we will have a look at this high speed 3G dongle.

   

 

Actually, there is another model Vodafone K4605 USB Surfstick which is also from Huawei E372. Vodafone K4605 is the high speed data card customized by the world's top operator Vodafone. K4605 is used for European customers. Except for the logo difference, Vodafone K4605 supports higher HSUPA speed up to 11mbps, while the upload speed foe Huawei E372 is 5.76Mbps. The upload speed of K4605 is almost twice faster than E372.

 

   

 

They both support the 42Mbps download speed with the DC-HSPA+ technology. But Vodafone K4605 could support only the 3G UMTS 900/2100MHz, which is available in Europe. Huawei E372 could support Qual-band for 3G UMTS/WCDMA 850/900/1900/2100 MHz, so Huawei could support any WCDMA operators anywhere.      

 

Then here comes Huawei E3251 USB Stick. It's in completely different system. Huawei E3251 is the new member for Huawei HiLink USB surf stick. As we introduced before, HiLink USB modem is very user-friendly, no extra driver needed, no installation and setup. It's really plug and play USB dongle. Huawei E3251 could also support up to 42Mbps Data rates, unlike Huawei E372, it has many sub-models, such as E3251s-1, E3251s-2, E325s-6. They are configured to support different bands in many areas or countries.  

 

 

We are glad to find all the three models have external antenna connector. Many customers has the demand for high speed, especially in remote areas, the external antenna is very important. Now all of them are SIM unlocked on www.4gltemall.com , which one will you buy if you need a high speed data card?

HUAWEI E3276 4G LTE Category 4 USB Surfstick Review

Today, we get the demo of Huawei E3276 4G LTE cat4 USB Surfstick. If we say 2012 is the beginning year of 4G LTE, 2013 should be the beginning of 4G LTE Category 4. LTE Category 4 develops from 4G LTE (also called LTE Category 3) and is more efficiency in data transmission. It could support 50% faster speed than 4G LTE Category 3 with peak download speed up to 150Mbps on FDD network. What amazing speed!  

 

 

The Huawei E3276 Cat4 LTE modem is the successor of Huawei E398 and E397, which are LTE category 3 USB modems. Huawei E3276 has been presented to public by many 4G operators all over the world. The Huawei E3276 we get is in white color, no operators' logo. It's in Huawei logo without original package box.

 

HUAWEI E3276    

 

The total design of Huawei E3276 is very cool, in vertical direction; it looks like a burning fire. On the front of Huawei E3276, there is Huawei Logo and beside logo, there is a LED indicator to tell users the connection status.

 

   

 

Just like Huawei E398, the Huawei E3276 is also in rotatable USB design, the difference between them is the there is a cap to stuck the USB for E3276, press the button, the USB could auto eject, so it's somewhat like the USB design of Huawei E397, but Huawei E398 doesn't have this feature.

 

   

 

The USB could be rotated to 2D total 180 degrees. It’s a user friendly design because it will save much space when connecting this dongle to PC, and it would help to get better signal strength.  

 

     

 

On the back of Huawei E3276, there is a stick, on which, we could see the model number Huawei E3276, Certificate information and place of origin.

 

   

 

At the below side of Huawei E3276, we could see the MicroSD card slot covers by a plastic cap. Open it, we can see there is a external antenna connector with the slot. And the other connector for pigtail is at another hole.

 

     

 

Push the back over towards to the direction to USB, the back cover could be removed from the body, and then the inner part could be seen. The Module of inner part is in plastic material, there is SIM card slot in the module. Above the module, there is the model nuber, IMEI number of Huawei E3276, and the S/N number. The model number is HUAWEI E3276s-150.

 

 

 

We get the information that HUAWEI E3276s-150 support 4G LTE FDD 800/2600MHz and 3G UMTS 900/1900/2100MHz with 2G GSM qual band 850/900/1800/1900MHz backward. And it has its partner model HUAWEI E3276s-151.  

 

In conclusion, the design of HUAWEI E3276 is cool and we believe the LTE cat4 dongle would give reliable high speed support for the users. Next time, we will have a test report for HUAWEI E3276 in near future.
