A:AnswerYes in that it acts as a standard WiFi access point. Any WiFi device can connect to it, but there is a limit of 5 simultaneous WiFi connections at the same time.
A:AnswerI don't think this device is programmed to run in other countries except for Mexico and Canada. However, you can rent an international mobile hotspot at a reasonable cost by searching online (e.g. Telecom Square).
A:AnswerIt doesn't matter who you use for your phone service. The mobile hotspot is between you and AT&T, and they charge dearly for the privilege. As long as all you need is email and limited internet surfing, it's reasonable. As soon as you start streaming data, however, you'll gobble up your data limit in no time.
A:AnswerYes u can it will switch over to the network in Canada but you will be reduced and can cap out the data plan faster than if you would be in USA.
A:AnswerYes it will work. Att owns cricket wireless therefore it uses att towers. I currently use the hot spot with my unlimited plan with cricket and it works great! Just dont tell cricket because they will block it.
