How to fix iPhone 4s No Service / Searching Problem?
How do you fix the iPhone 4s No Service/Searching problem? What causes the problem? Please help. Thanks.
5세대 iPhone. 수리는 간단하며 스크루드라이버, 비집는 도구 그리고 인내가 필요합니다. GSM/CDMA / 16, 32, 또는 64 GB / 검정색 또는 흰색.
A solution is to set the date and time manually. If you take out the battery on the iPhone (iOS 6.xx) the date will be 1970.. :p
When you have set the date and time, remove the sim card and put it back in.. This should work :)
(you kan also connect the phone to the WiFi to automatically set date and time. Do the same with the sim card, when the time is right :) )
You could also try to put in a sim card without a pin code, and then go to Settings -> General -> Cellular -> "enable 3G" or for iPhone 5 "enable LTE", if 3G/LTE don't show up, go back to General -> Cellular. And then se if it shows, enable and disable fast a couple of times and 3G should appear in the status bar. When it shows, wait for a couple seconds with "enable 3G" on, 2-3 seconds later disable it and enable it again. There you go, you should now be able to get a service, on operator locked iPhones, you will have to activate the phone, but then you could use your original sim card on the phone to activate it. You may have to activate through signing in with Apple ID.
Any questions just comment

My 4s Apple iPhone went into a searching and no service mode today. I contact my carrier att diagnostics were ran nothing happened. I was advised to go to an att retail store and have them insert a new sim, I did that. No service and searching continued. The att rep advised me to take to an Apple Store. I did not instead I went home. I telephoned Apple Store and was told I needed an appointment or either com in early close to when the store opens and I may get lucky to be on a waiting list. Oh I forgot to mention there weren't any available appointments until Tuesday January 9, 2017. Hm this happened on Monday January 2, 2017. In the meantime as I spoke to the gentlemen at te Apple Store he ran diagnostics and wasn't able to detect the issue. Later that night I decieded to reset the phone to the original settings. Later that night while had just fallen asleep I began to receive text Mssgs. I reached for the phone sure enough it was up and running, I noticed in the upper left hand corner on the screen it said 3G. Well anyway it's working again and no one helped me but me. Just sayin!!! Therefore if you ever run into the issue of your phone searching/no service do not hesitate to reset back to factory setting that may very well correct the issue and save yourself some time. Good Night!!!
The defect in the absence of service is by placing the phone on the flight mode and monitoring the signal if it takes a relatively long time. The fault is in the Ic besnamtT responsible for the network frequencies. If the time for the signal to appear, the files and the rest of the circuit related to the service
