I live in a rural area where traditional cable, fiber, and even DSL are not a possibility. I am using a weird wireless system a local ISP set up for this area, but its flaky, slow and expensive. The only thing it really has going for it is there are no data caps.
I can get 4G signal for T-Mobile, however (and Verizon, but their data caps drove me away), and I'm considering making my home internet connection consist of a dedicated Android phone on a T-Mobile 4G unlimited contract, using its WiFi hotspot. (I would probably set up another wireless router for the actual LAN so I'd have good coverage of the house, but it would use the phone's network as its uplink.). I would use a phone rather than a USB modem to take advantage of T-Mobile's unlimited data package.
Is this a bad idea? Would the phone fry if I left it on and broadcasting its WiFi hotspot 24/7? I have an N5 but I've never used the hotspot for an extended period before - are they flaky? Would it drop IPs or anything like that and require reboots? Would T-Mobile decide I'm breaking a rule and throttle me down?
