week ago i dropped my phone and when i turned it back on it just says no service. I can get signal but only in 1 tiny spot in my area and the connection is weak. Ive tried everything to fix it - Reset all settings, Factory reset, Reset network settings. I updated the IOS but still not a fix and the SIM is working in other phones fine. I tried other sims in the phone but same problem. Anyone any ideas? its strange that i can still get signal in some spots.
