Yesterday I changed my microSIM to another one. I suppose that it is so new that it will be 128K....
By now, my iPhone is working well. I still have not missed a call. Today in my train journey, I'll put it on fire test (when I drive during a call, I have a feeling that, caused by changing radio antenna, my iPhone loses the service).
I'll tell the results.
**** Iphone!!!! After changing my sim to another new one. The issue is still worse!!!!! I loss the net, the signal phone, more often!!!
Yesterday I ended a call, and a few seconds later, mi iPhone showed me "No service"!!!!
Arrrrrggggghhhh!!!!! This is shameful!!!!!!
Now, I have the No-service bug so often, that I am thinking so much about restore my iOS 5.1.1 backup!!!!!
Apple, YOU MUST SOLVE THIS RIGHT NOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! We are having this issue since iPhone 4s was released, and Apple has done/said NOTHING!!!!!!!
We want answers and you must give it to us.
Same issues here, but on the 3GS. Ro read a lot of articles, videos, possible solutions what the problem could be. First signal went away for short whiles, then longer and longer and now (also updated to IOS6) no signal at all. When selecting manual mode for carier I can see some phone cariers. Sometimes it picks up signal with all bars but still not able to make calls.
Simcard is working perfect in other device, and sim of a friend who has another provider has exact the same issues, so Sim is not the issue I think.
Tried a full restore; not working.
Checked the hardware if the antenna cable was loose; not working.
Resetted network settings a lot of times; not working.
Signal in foreign country; not working.
Now ordered a new module with antenna, microfone etc replacement to check if it is hardware related but the longer I read forums I don't think this is the issue.
iPhone has no simlock and is out of warranty so I think I have to pickup a new one.
Same issue for me with an iPhone 4s: 'no Service' failure appeared on last 27th when the software update to iOS6 was detected. So I updated to iOS6, but nothing changed.
I read possible solutions on the net, but, as described by most of you, nothing worked (neither full reset).
I've been isolated for 3 days, this is not acceptable:
I can live if I have a failure in one of the milion useless app, BUT A PHONE Is first of all a PHONE and no software update should jeopardize thi PRIMARY FUNCTION!!!
Really disappointed by Apple and its business model, I still wait to sede how it will be' solved.
I feel sorry for you iPhone issue.
Mine also suffer the same "no service" issue. I did research for any workaround like resetting network, try enabling/disabling airplane mode, even restoring to factory default. It seems that all those workaround is temporary, works at the beginning, but eventually, the same issue, "no service"
My phone was working OK for the first month with slight warm. After that, sometimes it went hotter and "no service" issue came oftenly, especially in area where no 3G.
I end up swapping the unit.
If you have the chance to visit the place where you can claim for warranty (e.g. Apple store, or the Carrier, or place where you bought), you can try claim the warranty.
Don't be surprise if your next unit still suffer the same issue. I heard a friend swapped the unit 4 times, as the first three was no good, and the 4th one works just fine.
Well, mine is over three years old so cant swap under warranty. It is also unaccaptable a software update can mess up your device so much it is unusable. It looks like this is an issue on all devices, so maybe the next one is not an Apple. Keep swapping devices is also not an resolvement in my opinion..
Strange! Only solution to no network issue is swapping your phone period!
Apple swapped my one under warranty.....
Regarding iOs 6 it's draining my 4s battery like crazy!! Guess those who are not having any problems are the lucky ones...combination of luck and assembly plants with parts from specific vendors!!!
