Pay As you Roam service
I just activated Pay as you Roam service.
I don't want to use any mobile data or make any call from overseas.
All I need to do is just getting the incoming SMS messages not even sending out.
I'm thinking to turn off the mobile data from my cell phone setting.
Is that enough?
Or do I still need to switch off by dialing *100*54831# not to use any data from overseas?
Hope to hear from you soon.
Thanks in advance.
