SMS - Number format


Q: I'm trying to send non-billed sms to UK mobile phone number using API, all my phone numbers start with 07 and have 11 digits, example:


But response from the server is 'NO CREDITS'. But we should have thousands of UK credits left. We sent non-billed sms to the same settings to the Ukraine, the difference is only in the telephone number. Can you please help in this case?


A: You should send the numbers in international MSISDN format, e.g. 07123456789 becomes 447123456789.

For Ukraine you will already be entering the numbers in international format for it to be working.
