Funny enough Huawei kit is pretty much the backbone of all cellular and wireless technology here in South Africa, from the cellphone batteries, to the actual base stations, to the antenna arrays that are connected to them. Also the most popular manufacturer of LTE routers, and I am using one, which is pretty solid as far as uptime and throughput, more losses due to the carriers losing connections due to power loss than anything else. I would have ot regularly restart it, because the mobile antenna it was connected to would lose it's backhaul, leaving the system in a locked state, and you could either reboot the router and thus get a reconnect when power was returned, or log in and turn off the WAN side, wait 30 seconds and turn it back on, getting the same result.
Power switch was faster though, and I should log in sometime and see just how many junk SMS's are in memory, because this device does have a valid mobile SIM number associated with it, and has VOIP POTS interface as well, though it is not set up, no real need to have another phone number, as I cut the landline cord last year. Will get a random one from an online seller if I need a number for some reason,
