IPhone 3G Will Not Connect To Internet No Matter What

i've been living in a motel for the past couple months, when we first moved here, my internet on my iphone 3g was fine. i was able to search things, use pandora, send imessages, etc. but we recently moved rooms, and after moving rooms, it won't connect to the internet. i thought it would fix itself after a while, but we've been in this room now for nearly two months and it won't connect.Â

Tonight i decided to try some methods others have posted . I soft rebooted it. I hard rebooted it. I backed it up and restored it, putting backups back on it. I restored it without putting backups on it. I removed and then put the sim card back. I played around with the cellular settings. I turned airplane mode off and on about three times. I reset network settings

All of which didn't work. i also thought maybe walking back over to our old room would let it connect to the internet over there, nothing happened with that either.Â

iPhone 3G, iOS 6.1.6
