After I updated my iPhone 4 software from iOS 5.1.1 to 6, my signal became so weak. No Service - 1bar - Searching - No Service and 1bar again.

plus the battery drains fast. 


I also did "reset Network setting" And " Reset All Setting" and the problem still the same.


can someone help in how to fix this annoying problem.






iPhone 4, iOS 6

    Hello, I'v got same problems with the 3GS in combination with T-Mobile. My wife also with her brand new iPhone5!! Sold today from Vodafone.

    Since iOS6 signal strength is hopeless. It bounces all the time, being far from stable.


    Apple please quickly release a path and return service to normal stability.

    I am having something similar, but for me is not one bar. that is 5 bar full (which seems not really make my phone reception weak, rather it go random).


    I am now in a situation that make me frustrated, it can be having prefect signal, it go weak, No Service and come back. After a while it repeat. This is in good situation after I reset all setting. hopefully it will not go even worse.


    before I reset, after it go No Service, the phone seldom come back, it stay for no service for quite a long time, can be for whole night, until I restart the phone. Because of this problem, I also tried restore my phone, which dosen't change anything.


    Now I would love to know some fix that can get this problem away, or at least we know in what situation that happened, then we can try to avoid.

    I am facing the same problem on my iPhone 4 after upgrading to iOS 6. Signal is weak and sometimes phone gets stuck in searching/no-service until I restart it.

    Did not have the problem on iOS 5.1.1

    Same situation 'no service' due to network restrictions is the error message - eventually corrects after turn phone on/off 3 times - how frustrating !
