Hi Saida,

 

If you are asking about how to format the phone number, it could be in this format:

+{International_Access_Code}{area_code}{local_phone_number} (without space or dash in the middle)

For a Canadian phone number, it should be +1{3 digits area code}{7 digits local number} (+15145718888)

I don't think it's documented somewhere officially about the SMS restriction, but there are many third party libraries out there helps you to tell if a phone number is too long, or whether the length fits the country code, for example libphonenumber from Google.
