Problem: Sony Z3+ keeps switching on mobile data network itself. Why?

[AC Question]

Problem: Sony Z3+ keep switching on mobile data network itself.

i have no mobile data plan at this moment so i often disconnect mobile network and mainly use wifi.

but i found it sometimes auto connect to mobile network as i would receive SMS telling me i was charged for using mobile data.

it's so annoying. Anyone has the same problem and gets any solutions?

Is roaming off?

roaming is off, but it sometimes turns on mobile data unexpectedly.

Z3+ seems lacks of "data traffic" option compared to Z3.

U may have an app that could be doing this, like location look up etc
