Kindly register for a prepaid SIM that allows international SMS.

According to many customer's feedback, standard Prepaid SIMs does not support international SMS, which means calling back to home country is impossible with these SIM cards.
Although these SIMs are easier to acquire, because they do not require registration, we recommend that you ask for a SIM card with international SMS capabilities before purchasing.

So long as your mobile is still turned on while overseas, calls may reach your mobile. If you accidentally picked up, that would be a roaming call charged by your mobile provider.
And even if you reject the call or let it go into voicemail, call charges by your mobile provider are still applicable.

Therefore, as a safety measure, please switch off your phone while overseas and enjoy unlimited calls using FlexiRoam at local rates.

The conventional way to deactivate call forwarding for most phones is to Dial #002# with your home SIM.

For iPhone users, if #002# does not work, please try #21# or #62# to deactivate call forwarding.

For other smartphones, when you reinsert your home SIM, always restart the phone before deactivating call forwarding (Dial #002#).

This will ensure that call forwarding is properly deactivated when you arrive back home.

NB:
If you do not deactivate call forwarding, you will not be able to receive calls as your calls are still being directed to your overseas SIM.

The best way to get data while you are overseas is to purchase an overseas SIM card with a data package. This way is the safest way to use data overseas because data roaming charges are extremely pricy. In overseas, many mobile providers may offer a variety of unlimited and affordable data packages for travelers visiting their country. It is therefore recommended that you ask the sales attendant on how to activate the best unlimited mobile data plan available, at the point of purchasing the overseas prepaid SIM.
