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. For 4 years I put up with having a top download speed of only 2.7Mbps yes 2 point 7 Mbps. Wish I could attach the speed test and don’t laugh if it seems slow to you because you're in the USA.
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. It did require some APN setting edits but all relatively easy. Pity I can't find one to cover all the Verizon bands.
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." Perhaps I should invest in the antennas for better signal reception.
Summary: I just got my router and it works flawlessly with my sim card. Mine is completely unlocked and worked out of the box. Getting triple the DL speeds and 7x UL speeds without antennas! Cutting my cable internet right away.
