iPhone 4S keep searching for network after replacing battery

As some people have already suggested, first try switching on wifi, if that doesn't work, try changing the date and time manually to the correct ones as it will likely have set itself to Jan 1970 or something similar when you took the battery out.

If neither works, also try checking the cellular antenna and that it's in the right place (NB. the pics in most of the guides on here actually have it in the wrong place - it needs to go around the left of the standoff then to the right of the metal finger)

You could try a restore in iTunes that fixes the problem most of the time but if you have no internet iTunes won't work as it needs internet connection

Turn on airplane mode then wait for a while before turning it off again works for me.

Change date work!

you can follow this guide (it will tell you the needed parts, tools, and steps) to replace the battery. https://www.youtube.com/watch?v=_sUv3sQb...

I have the same problem but I noticed a tiny part was missing near the port connection on the motherboard!

When it's not the time/date thing in the 4s, then it will be pry damage from removing the battery. Look for missing components along the edge of the board

Do a restore and use WiFi to activate, while it searches for the Apple server insert sim before next option. Do this fast

Easiest way to do. Use your friends iphone, make a personal hotspot with it. join the wifi created by the other iphone and go reset the date and time by switchin it to manual and back to automatic and it will retrieve the info from your friends iphone network. After this restart phone. I tried my home WIFI and it wouldnt work with that because theres no info for apple available.

Had the same problem, phone picked up the WiFi no problem but continued searching for the mobile network. I was able to make and receive calls the entire time, and it had the correct time and date.

What worked for me: I changed the time manually to a few minutes off the correct time, then turned on the auto time and date. The phone reset the time to the correct value and found the mobile network.

Good luck.

Hi all, i had this issue recently and none of the above worked for me but what did work was going into setting > general > reset > reset network setting. once doing this phone picked up signal again :)

My own is not working even my time and date it right
