To send or receive SMS messages with Sinch, you will need a virtual number from Sinch. A virtual number is a standard telephone number that is not locked down to a specific phoneline. It can route a voice call, text message or fax message to any phone or application workflow. 

Sinch provides a complete range of carefully-tested phone numbers for most countries, to use with all your communication services from Sinch. You can get numbers that are set up for SMS, Voice, Fax or a combination of these. You can buy a number from any country where Sinch has numbers in inventory. Countries with numbers available for rental are marked with Direct Access. All other countries will require you to submit a request to Sinch for manual handling.

Note: When you get a virtual number supporting documentation may be required and will need to be submitted before the transaction can be completed. If this is the case a message will be displayed at the bottom of your form (in an orange box). Learn more about supporting documentation.
