Q: iPhone 4S "no service" problem
-
Jan 20, 2012 6:08 AMby mritacca,I have to say it's a mix between hardware and software.
The signal drop is software as when you switch from 3G to Edge, it resets the bars (prior to iOS 5, it never use to do this) it did it smoothly and without dropping the signals or calls.
The Searching / No Service bug problem that I had was with my SIM card. I replaced 3 of them and now it works better, but still not perfect.
I believe the problem could be hardware too. That is why Apple hasn't come clean yet. Also notice how long it is taking for them to release iOS 5.1? That's because a lot of problems are still within iOS 5.1 beta (almost a 3 month cycle)!!!

Jan 20, 2012 7:02 AMby bademus,I have been having this problem for about a month already. I've tried everything that's been suggested here: I changed my SIM card, installed the latest build (9A406) of iOS 5.0.1, but the problem is still there.
The phone loses network all the time displaying "no service". The only way to get it back is to try to make a call and after the call fails it starts searching and after a while catches the network. Then I can make some calls and after 10-15 minutes it drops the network again and the process repeats itself.
It's VERY frustrating indeed. I bought the phone in Rome in November and for a month it seemed to work fine and then the problem started. Sometimes it displays "SIM failure" and I have to restart it to get it to work. I'm not sure if it started after I upgraded to 5.0.1, and do hope it's a software issue.
If after 5.1 the problem isn't fixed, it's suely going to be my last phone from Apple, which is very sad, since I've had three iPhones and this 4S is the worst phone I have evere had.

It seems as if your mentality is "We already got your money. Why not work on something else that will get us more money" What a slap in the face

Jan 21, 2012 8:45 AMby bademus,In my case it's got another interesting symptom: I can't make a call, but Siri does work. I can sometimes browse the web as well. For example, I ask Siri to make a call, and she dials the number, the call fails, after that the phone goes into the search mode and picks up the network. Weird...

There was "no signal" non stop, search and no signal... try everything, no success. than I made a restore, but the problem persists. I tried with sim card from another operator, it says activation required.... I put back my sim, and than it start to work again Messy, but works.

take videos and pictures and post them on YouTube. Title it 'iPhone 4S No Service / Searching' bug and let the world see it.
I am going to wait one more week and then going in for a replacement costing Apple $200!
If they don't want to support us or advise us of a fix in the works, then I would strongly suggest you doing the same and replacing your iPhone and SIM card.
Apple will have to eat the $200. Replacing your SIM card I would get your carrier involved and point them to this forum.
I have waited since November for this problem to be fixed and Apple has no plans to hurry and fix it as I think they can not. I paid for a phone to work as a phone.
