After a hard fall my iphone on sparadicly recives any sort of signal, 3g or network. What would be the most likly cause of this?
Two main reasons this has happened
- Loost antenna connection due to impact force
- Damaged logic board If the antenna has become loose, all you will need to do is remove the back cover and re-seat. If the logic board has been damaged then you will need to take your phone to apple and request for a replacement.
you can change your sim card and try it .if that your cellphone doesnt work ,maybe it was broken.
