TM4B Bulk SMS Gateway

Inbound Number Support

To receive SMS from mobile users in the United States, you can use our American virtual local numbers.

You can lease a dedicated American virtual number or, through keywords, use our shared virtual local number +1 657 777 4800.

Please note that our American virtual numbers are intended to receive SMS from mobile users in United States. There is a high chance that they will not receive verification SMS or SMS sent from other countries.

Receiving Options

At a basic level, all of the SMS that you receive will be delivered to your SMS Inbox and can be forwarded to you by email. For more advanced handling, we can forward your SMS to your server through a webhook.


I have found tm4b's customer support professional, responsive and focused around my needs.

Although I sense they deal with a great number of people, they have always offered me a personal service, with a named contact who always answers emails.

The web front end is elegant and designed for usability. I have found the API usable and well documented, and the ticket based support system is efficient.
