How do I send an SMS message to a SIM card?

To send an SMS message from Things Mobile to another operator, you need to put the country code before the number (for example, if you need to send an SMS message to an Italian operator, the prefix is +39 or 0039). If you need to send an SMS message to a Things Mobile SIM card from another operator, enter the full number with +88 (including the “+” symbol) before it. The cost of sending an SMS message from another operator to a Things Mobile SIM card depends on the operator’s rates.
