Sony Xperia M5 Wireless and Mobile Signal Issues

If you are encountering weird problems using your cell phone Sony Xperia M5, you have tried many thing but it is still unstable?
Then you shall try to change the default carrier mobile network type from default LTE to WCDMA.
This has fixed my issue, so maybe can solve yours too.

Sony Xperia M5 telefonunuzda garip kablosuz ağ veya mobil sinyal çekmeme problemleri yaşıyorsanız, varsayılan mobil ağınızı LTE den WCDMA ya değiştirmeyi denemelisiniz.
