Appendix - Sending SMS/MMS to international numbers
Mobile infrastructure and supported features vary internationally and some do not support SMS/MMS.
If this is the case and you have a smartphone, you and your recipient may want to try an instant messaging app like Skype, or simply send them an email.
If you know that the mobile network of international number you’re messaging does support SMS/MMS, then make sure the number is dialled correctly. The country code should replace the first zero in a mobile number. If the first digit of the mobile number is not a zero, then just dial the country code before the entire mobile number.
Example: Messages sent to a London mobile number 07937 123 123 should be dialled as +447937123123.
