How can I send an SMS to the SIM card?
To send an SMS from Things Mobile to another operator, you need to prepend the international dialing code of the country (for example, to send an SMS to an Italian operator, the prefix to add is +39 or 0039).
If you need to send an SMS to a Things Mobile SIM card from another operator, you must use the full number starting with +88... (including the +).
The cost of sending SMS from another operator to a Things Mobile SIM card depends on the tariff plan of the operator.
