I have an IPHONE 4 - IOS 6.0.1
Last 1 to 2 months I have had problems with "APN" and "MMS" settings.
They disappear after 1-4 days without reason.
I need to enter settings manually each time.
Have got a new SIM card - did not help. Think there is a problem with my phone. It's almost 2 years.
Any tips?
iPhone 4, iOS 6.0.1, New sim card
same here on iPhone 4S, it began on 6.0.1, same on 6.1
changing carrier didn't help
apn settings just disappear after a few days of use + mobile internet won't work often after I use WiFi for a long time, for example if I'am on WiFi all day while within my office and then just turn WiFi off and go out - it won't connect sometimes even though APN is there and it's correct. gotta torn AirPlane mode on/off to make it work again. resetting network settings didn't help either. gotta restore today to 6.1 to see if it'll help.
forgot to mention that my problem is not about mms, it's about mobile internet's APN setting, but I guess it's pretty much close
APN and MMS settings deleted every 2-3 days last 1 to 2 months
