Hello, I have a problem with my Sony Xperia m4aqua namely the lack of coverage, it is impossible to call but when I enter the settings and I search for the network it finds available but I do not want to register, I exchanged softa but still the same as the reason? I will mention that if you ask...

The phone was not flooded or flooded at times?

Well, that's what I do not know and probably never will

Try to replace the bottom plate which is under the loudspeaker because there is something wrong with it.

it's just weird that it looks even in LTE but does not log into the network

Whole antenna without damage ??

All and how much can this lower plate with antenna cost? Maybe there is a micro-crack and it does not work for that.

I do not know. I did the same with Sony after replacing the plate with the antenna was ok

The replaced circuit and range has appeared but the connection can not be established Added after 2 [hours] 45 [minutes]: So any suggestions on where to look for the reason?

Hello M4 repaired in 80% range is possible to call but only on the settings of the manual search network Play (plus).

Hello. What is the origin of the phone? Are you the first owner? Was it somewhere bought olx, on the housing estate from the level ?? This is probably the phone blocked by imei by the operator. There may also be damage to, for example, the antenna wire, the transmitter, something chipped on the bottom plate ... The fact that it works on the plus side may be due to the fact that the phone logs to it on 3G or GSM 1800. And on LTE900 or GSM 900 will not be. Greetings.

I will mention that if you ask him, he will send an SMS or receive it if someone writes it, but the microphone does not work and the sound is playing or is it somehow connected?

Hello.

What is the origin of the phone?
Are you the first owner? Was it somewhere bought "olx", "on the housing estate from the level" ??

This is probably the phone blocked by imei by the operator.

There may also be damage to, for example, the antenna wire, the transmitter, something chipped on the bottom plate ...
The fact that it works on the plus side may be due to the fact that the phone logs to it on 3G or GSM 1800. And on LTE900 or GSM 900 will not be.

Greetings.
