Summary: Recognize the network but never connected. Tried 4 different networks in two different countries on two different continents. I am very disappointed about this router. The set up is pretty simple but the result is very bad. Do not waste you money.
Summary: It's a great mobile modem, I'm currently using it in a 4G network, and it works perfectly. Setting it up is easy all you need is to insert your data SIM (full size) to start enjoying the connection to the internet. Watching videos and/or movies over the internet is amazing with no buffering issues.
Summary: So fast using this industrial router (4G LTE Model B593s-22) instead of the local service companies that just keep cheating users by limiting Bandwidth. Using this type of outdoors antenna too; GPRS GSM 3G 4G LTE TS9 plug 35dBi antenna.
Summary: We bought this for DR connectivity. I'm in the US, so setup might be different than others but I had to change the APN (General Settings > Wireless Settings) to "broadband" before it would connect with AT&T. After that, worked flawless.
Summary: Maintaining an Internet connection while travelling in an RV is challenging. I use Verizon and AT&T Pay as you GO and chagre each card up every time we travel. I use the Huawei for my AT&T connection and I have to say I have been very impressed with the speed and connectivity of the unit.
Does what I bought it to do, too bad my living quarters aren't closer to a cell tower.

Summary: Good product, I bought this router to use in Saudi Arabia with the STC carrier with no contract 4G LTE Internet. The area I live only allows a signal strength that gives me a max of 12 Mbps Download and 8 Mbps upload. Not the upper limits of performance, but so much better than what is "provided.
