iPhone 4S Network Searching.... Vodafone


Well-known Member
HI there

Phone and all was working all fine last night and i switched it off. When i turned on this morning, it would not connect to Vodafone signal and is constantly searching.

I've reset network settings and done the press home button & power button topgether but it's still searching.

The Voda network is ok as i've got a spare phone on Voda that's working fine - any ideas please?

and i've just removed the sim card (and left it out of the phone) and turned phone on and off and it's still searching. I thought it would have said no sim??


It seems to be a known issue, and the "special" iP4S iOS 5.01 got released which only fixes this issue:
New iOS 5.0.1 Build 9A406 Intended to Fix 'No SIM Card' Errors on iPhone 4S - Mac Rumors
In certain situations, iPhone 4S may have difficulty recognizing a micro-SIM card, resulting in the following behaviors:

- "Invalid SIM" or "No SIM Card installed" alert appears intermittently.
- Status bar displays "No Service" or "Searching" in a location with good network coverage.
I get "Searching.." too, typically after i move out of network coverage, and it can take quite a while to refind the provider. This can then lead to a kernal crash, as i think it either overheats or runs out of resources.

Thanks Stinja. I tried my micro sim in a friends iPhone and it worked fine. I assume i'll need to try the restore first to force the "special" iOS 5.01 (9A406) as currnetly i'm on 5.01 (9A405).

My phone just keeps saying "searching" all the time.

Roll on home time!!

Just finished the download and restore. Then restored phone from my back up and Voda is back :)

Just hope I don't have to do this too much! Took about 1 3/4 hours in total!!
