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.


We've been using tm4b for more than one year now. Their tech people are helpful, friendly and available. Servers seem to be fast and uptime good. I strongly recommend this company as SMS gateway.
