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.

HUAWEI E368 VS HUAWEI E369 HSPA+ 21Mbps USB Dongle

When we first see the Huawei E369 Himini 3G data card, we were attracted by the smart design and the slimness. There is only 8mm for thickness, and there are many optional colors available. The design and color should be the one of the factors that attracted us.

   

The most important is that Huawei E369 HSPA+ USB Surfstick has great ability to be compatible with the almost all the 3G WCDMA/UMTS networks. The UMTS bands that it could work not only include the 850MHz, which is common American 3G bands, but also 900/2100 MHz, the popular band in Europe.  

What's more, Huawei E369 supports 3G WCDMA AWS bands(1700 MHz). The AWS bands are available in only a few countries, such as Japan and USA. So if you are lucky to have a Huawei E369, you could travel around the world and it will keep you connected with network without compatibility problem.    

Huawei E369 supports maximum download speed up to 21Mbps, under current network status, this should be a good speed that most user can't reach even in good network atmosphere.  

 

Perhaps because Huawei E368 is customized by the US operator AT&T, we didn't see Huawei officially released this 3G USB dongle. It's also named by AT&T as Unlocked AT&T USB Connect Force 4G E368. Unlike Huawei E369 compact USB design, Huawei E368 is in rotate USB design. The USB could be rotated for total 360 degrees. It also supports HSPA+ peak download speed up to 21Mbps.  

 

To work with the AT&T 3G network, Huawei E368 supports 3G UMTS 850/2100 MHz that Huawei E369 could also work with. So if you have HUAWEI E369 in hand, it can work like E368 to keep connected with network for surfing.    

However, HUAWEI E368 has some features that HUAWEI E369 doesn’t have. HUAWEI E368 has MicroSD card slot and external antenna, in this point, HUAWEI E368 would be more powerful. Because with the memory card slot, user could read file from the card and if in remote areas, external antenna would help to get better signal strength and higher speed for data transmission.

In most cases, HUAWEI E369 would be enough for users to get connected with Internet. And HUAWEI E368 would be optional if you need the antenna or memory card functions. In conclusion, they are both reliable 3G USB modems. If you want any of them, welcome to shop from www.4gltemall.com .
