Inbound Number Support

To receive SMS from mobile users in Puerto Rico, you can use our Puerto Rican virtual mobile numbers.

You can lease a dedicated Puerto Rican virtual number or, through keywords, use our shared virtual mobile number +1787 4895 404.

Please note that our Puerto Rican virtual numbers are intended to receive SMS from mobile users in Puerto Rico. 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.


When I first signed up to tm4b, I thought that sending text messages through custom developed applications would be difficult. But how wrong could I be?

Since signing up for tm4b, I have found the system easy to use, easy to manipulate and easy to integrate into everything my business is trying to do.

I would have absolutely no hesitations in recommending tm4b to anybody who wants easy, quick, and most importantly, functional text messaging services. It is, far and away, the easiest to use text messaging solution on the web.
