Iphone data stopped working?

My friend gave me his old iphone today because the data wouldnt work. He had sprint and the sign would show up and the bars, but not lte or 3g or anything so it didn't work. I have cricket and all day it said searching for service, and eventually my phone died and i turned it back on and it was working with my data. An hour later it now says searching again.

Sounds like maybe sim card issue. Id try a different sim card in it and see if does same thing. Also try to reset network settings

If the phone is bent this will usually mess with the sim slot… Let me know if its not bent I can give further instruction

  • Why iphone 3G games suddenly stopped working, the app open and closes instantly? Hi I noticed from last 2 weeks that my iphone 3G games which used to work perfectly fine suddenly stopped working. Whenever I try to open a game, it opens for a split second and closes immediately. I even tried rebooting my iphone several times but that didn't help. Please advise if you have any pointers.

  • My iPhone charger stopped working I left my charger at my grandmother's house, so I borrowed my mom's charger for a while. Tonight I plugged it up to the wall and it was charging just fine. I plugged it up to my computer to sync something from iTunes and it was saying "USB device not recognized". Then I plugged it back to the wall and it still wouldn't charge. It hasn't been charging since then, and my phone is on 10%. What do I do?
  • My iPhone 4S's sound has suddenly stopped working! How do I fix it? **Please READ** So I searched online on different reasons why it may not be working. Someone said that the headphone slot may have dirt in it leaving the iPhone to believe that there's still headphones in it… Well I blew on it and nothing came out. I also plugged in my headphones and still music wouldn't play or text tones/ringtones.nothing! I know it is not water damaged because I have not gotten it wet or anything. Any ideas?
