how about incoming or receiving sms? Chargeable? Need activate data roaming? thanks
Prepaid for most telco international roaming (IR) is activated by default. You may check with customer service before leaving country.
With IR, you can make/receive call and sms, and if you do not need to use data, please turn off DATA ROAMING in your phone settings and recommended to choose 2G/3G as your preferred network.
For call/sms roaming rate you can check the service provider website.
In summary when you are roaming:
Making call -- Charge
Receiving call -- Charge (Please deactivate Voicemail service before leaving Msia as it will be charged as receiving call)
Send SMS -- Charge
Receiving SMS -- Free
