Does anyone's iPhone lose connection?

Question

iPhone

From time to time my iPhone 4s (5.1.1) loses connection. I mean, don't call me. In the status line, “MegaFon” and the signal level are displayed for the worst, but there is no way to get through to me. You have to restart your phone or disable and enable Cellular Data.

Anyone faced the same problem? How to decide? Is this a phone/firmware issue? Or Megaphone?

Answer 1

I heard about such a problem with MTS, a glitch occurs when switching to 3G. It seems to be a school of opsos.

Answer 2

It happens from time to time, MTS, four. And this is from the time of the first generation, and I had everything except 4S. Flashing does not help, I sin on the operators - more familiar with some of the chief operators. Until a roasted rooster pecks them, they don’t climb into the equipment settings. And they themselves admit that there is a dark forest.
You can turn on airplane mode for 3-5 seconds so that the phone re-registers in the cell.

Answer 3

Do you always have 3G? Not? I had this before. The entire channel is clogged with edge and the call cannot go through. Change carrier or complain.

Answer 4

I have this problem too. Also in St. Petersburg, Megafon. I have 3G enabled. Maybe, indeed, because of this ... I'll try to turn it off until I use it.
