Im in US and I have a data plan for the US. I'm unable to make any 1800 calls and my SMS messages are failing.Im on T-Mobile. I have turned my iphone on and off and no change.
Thanks to everyone for helping me out. What helped with the failing SMS messaging is turning on Airplane Mode, waiting 30 seconds and turning it off to refresh my cellular connection. My SMS messages are now going thru. Thanks again
