mobile data not working properly

[roscoe8000]

If leave a wifi area my xperia z2 doesn't start to use mobile data, so I have to reboot like ten times a day...
Also i even lose mobile data without entering a wifi sometimes.furthermore the signal is pretty weak compared to my old xperia Z 😞

Do you have location based wifi on?

[roscoe8000]

Not sure what u mean, but I guess so...

Just wondering, is the Internet Setting done properly on your phone?
Go to setting, pick more under and wireless and networks. Then you pick your carrier name from the pop up

Location based WI-FI can be found under power management in setting

[roscoe8000]

Yes, the Internet settings should be correct. Access point name is my carrier (t-mobile). I just refreshed the settings. Location based wifi was off. I remember I read somewhere that it's a hardware problem but I lost the link...
Just happened again, it's driving me nuts!

Is it like this from day 1?
Of yes, make sure that T-mobile have your 4G service turned on.
Of that is not the problem see if a different SIM card is necessary. I remembered reading somewhere that T-mobile subscriber finally got data working on his Z2 after insisting his/her SIM replaced with the one for S 4

[roscoe8000]

Yes, but only with this device. I've been using this sim for over a year with my xperia Z (not Z2) without any issues...

[Xperyan]

Do you have anybody that have t-mobile SIM that you can borrow to test?

[roscoe8000]

Yes. I'll try that and let you know then... But since today morning I didn't had any problems. The only thing I changed was the location based wifi from off to on.
