If I add $15 Voucher to my profile will that be use on my next renewal date automatically and rest of the plan charge going to be taken off my credit card? is this how it works?
@fixin In that case, i would suggest using the automatic option but if face any problem try to switch the operator in between. Make sure you restart the phone each time when you select the operator manually.
I went to the USA yesterday, all i needed to do is turn on the DATA ROAMING. For the calling and text you do not need to do anything at all. But if you face any problems using data you can manually select the T mobile network which is pretty good.
