A:AnswerI just purchased this hotspot because my wife and I moved out to the country where cable & internet are non existent. So far, even with one bar of service the speed has remained plenty fast. I haven’t done a speed test yet, but I planned on it once I add the directional antenna.
A:AnswerThe AT&T model is locked to the AT&T network, but there are unlocked versions that can be used on other networks. I am using the AT&T model on Consumer Cellular which uses the AT&T network.
A:AnswerWhen I got mine, I added another line of service to my plan for $10/mo. Not sure if you can simply change the SIM card, but can't see why it wouldn't work. Hope that helps.

A:AnswerThe latency depends on a number of factors.
I am locked onto a tower near the interstate. Latency is very low throughout the day, but during rush-hour, when the interstate is bumper-to-bumper, latency is much higher, and speeds are much lower.
