stamina mode is not on
data limit is not enabled
sim is good
factory reset the phone
ever since a Z3 update a few months back my mobile data stops working. it doesn't say it is off but internet or data (mms) fail to load and it says that it is not connected to the internet. I have to turn it off and on again for it to work then it turns off again in 5-10 minutes. This is getting really annoying since I run a business and do not get notifications when I receive new emails. No, the data doesn't turn off when the phone is asleep, it comes and goes even in the middle of a skype call or browsing the internet. Any idea of what it might be? by the way, the last update sucked a lot, no idea what you were trying to fix sony, but you broke more in the process.
edit: no it is not the data connection, full bars here! this only started happening right after that horendous update. all apps were deleted, phone was factory reset numerous times and problem still persists.
