If you send SMS, you're probably paying for undelivered messages.

Most SMS gateway companies charge for these. We think it's time this changed... At The SMS Works, we only bill you for delivered messages. It's a fairer and more transparent way of working.

We hope you agree.

Reliable Tier 1 connections

We only use the most reliable tier one connections, direct to UK networks. Messages sent within the UK stay in the UK. We never use international or SMS grey routes.

 Grey routes and why you should avoid them

Fast, reliable, robust

We’ve invested heavily to make our SMS API as reliable as it can possibly be. Our platform has been built to withstand the rigours of the most demanding applications.

 Technical Overview

Only pay for delivered messages

We only charge you for delivered messages. Failed texts are credited straight back to your account. Our delivery reports give you a detailed outcome of all texts sent.

No nasty surprises

We won’t tie you in with contracts or minimum SMS volumes. We run a simple, pay-as-you-go service. You can buy credits via PayPal, card or bank transfer.

Credits don't expire

Once you’ve bought SMS credits from us, they stay in your account until you want to use them. Current credit levels can be checked at any time.
