Brief technical overview

SMS API documentation

Clear Documentation

You need clear, concise, unambiguous documentation, with copy and paste code examples. We’ve put together just that in our
Developer Zone.

Straightforward authentication strategies; simple, clear method naming; standard http methods; example payloads; status message codes & error responses.



Low cost SMS gateway


Low and fair. Our SMS prices are amongst the lowest and you only pay for delivered messages. Failed texts are credited back to your account. (SMS prices start from just 1.45 pence + VAT per text with our credit doubling offer.) On average, our SMS credit prices are 33% lower than our competitors.

See our SMS price comparison table to see how we size up with other SMS gateway service providers.


UK SMS Routing

Our SMS service uses only tier 1, direct connections to UK mobile networks. We never use unreliable grey or international routes.

SMS grey routes are notoriously unreliable, often causing texts to be delayed or not delivered at all. Read more about why you should avoid SMS grey routes.

Have you found a UK SMS API Provider at a lower cost?

It’s unlikely, but possible. There are dozens of UK SMS companies and some of them have special offers for new customers that disappear after you've made your first purchase.

It's a good idea to make sure that the price you're being offered will stand the test of time.

If you have found a lower SMS cost and the company is offering the same high quality tier one routing, we’d be more than happy to match it and in many cases beat it.

Bear in mind that our delivered-only pricing represents a significant saving over most other SMS API providers.
