Internet loss when i unlock screen

[mrBrocky]

Hey all, 

any time i unlock my phone screen it takes uptoo a minute for any of my apps to connect to the internet, facebook, snapchat, outlook all seem to be effected. if i use the phone for a prolonged time i often get a loss of data. 

sometimes even a loss of network and a message appears saying cant access sim card. 

has anyone had similar issues and if so have they been able to find a solution.

Seems something related to ur sim card,remove it and check if it's clean and put it back.maybe you need a new sim?

Stamina clock under power management is responsible for delayed Internet when unlocking screen just turn it off.

unfortuanely this has not fixed the issue, the phone seems to lose connectivity to the sim card ( which has changed) would it be better returning it to sony or to the store it was purchase in ( at start of november)
