Automatic number detection
We automatically format numbers for you. You can set the default country under:
SMS -> settings -> default country code
This means you can supply a number in local or international format and we'll automatically format it.
Via our API
If you're sending via our API, you can also supply the 'country' parameter (optional). This will let you supply a phone number in any format, including local format for any country. Simply add the 2-character iso country code e.g. country="US".
