We purchased this tablet to be our hotspot. The only problem is we live out in the country and the hotspot has the same trouble as our cells phones. My husband has a 3G cell phone and I have a 4G cell phone. He can usually make and place calls, I cannot. I would like to be able to use our hotspot out in the country as we are limited with data with our home plan to 25G per month. It would be nice to supplement with what our hotspot provides as well but cannot connect to a tower (3G). Can you switch the tablet to locate whatever tower is closet not necessarily the best (4G).
