We'd love to become your SMS API provider.

Receive SMS replies to your text campaigns with a low cost reply number. SMS Replies can be routed back to you by email or we can simply post replies to a URL of your choice.
A free 7 day trial allows you to test the long code service before making any kind of commitment.
Running out of SMS credits is one of our customers' biggest concerns. The last thing you need is crucial texts to stop because of an admin issue.
That's why we're happy to arrange a free SMS API credits overdraft. If the SMS credits in your account fall below zero, your text messages keep flowing. We'll keep you up to date with low credit warnings too. There is no charge for this service.
We only use the most reliable tier one connections, direct to UK networks. Text messages sent within the UK stay in the UK.
We never use international or SMS grey routes to send and receive SMS. Although low-grade, grey routes may seem like a great, low-cost SMS option, they are notoriously unreliable.
Learn more about SMS grey routes and why you should avoid them.
Your test account comes with 50 free credits, so that you can be absolutely sure that our service is right for you.
We won't tie you in with contracts or minimum SMS volumes. We run a simple, pay-as-you-go, SMS API service.
Our aim is to make integrating with our free SMS API for developers as fast and frictionless as possible.
We only charge you for delivered messages. Failed texts are credited straight back to your account.
Almost all SMS companies charge for failed texts, when they haven't been charged themselves. You can save you as much as 18% by not paying for undelivered texts.
Our delivery reports give you a detailed outcome of all texts sent, including refunded SMS credits.
Once you've bought SMS credits from us, they won't expire. Surprisingly, some SMS providers remove your credits if they haven't been used after 12 months.
Current credit levels can be checked at any time, using our simple delivery reporting tools.
Sometimes, you'll have questions that aren't quite covered by the https API documentation. When that happens you'll want a quick response from someone who can answer your questions.
That's why we always get back to customer support questions within the hour. Our objective is to have you up and running with your SMS integration in the shortest time possible.
"Your efficiency is always astounding. Thank you!"

Connect The SMS Works with other applications using Zapier. No coding is required. It’s a quick and easy way to automate sending an SMS.
An SMS API (Application Programming Interface) is a set of tools which allows the capabilities of one computer application to be made available to another, so that SMS messages can be sent and received.
The API specifies how software components should interact and follows a set of predefined rules, allowing developers to build SMS-based workflows into their own applications.
How does an SMS API work?
An SMS HTTPS API simplifies the whole process of sending a text from a system to a mobile handset.
It acts as a bridge between your organisation and your customers or members of staff.
The SMS API removes the hassle of having to write and deploy specific code to handle the complexities of multiple mobile phone networks that operate different protocols and infrastructures.
For a more in depth description, take a look at our simple explanation.
There are additional costs in integrating with the new supplier and there is always a danger that the new company doesn’t perform as expected. We understand these concerns and wanted to try and put a couple of fears to bed and explain why the benefits outweigh the risks.
In our experience, this is never as bad as feared. Most Rest API companies have similar approaches and often the code changes required are quite modest.
Our copy and paste code snippets go a long way to simplifying the process and we’re always on hand to help out if needed.
Customers tell us that above everything else, reliability is the single most important factor; even more crucial than SMS API price. We really understand this and we’ve put in the work to make sure that everything’s in place to provide the best SMS API online possible.
For a quick summary, take a look at our technical overview.
Our REST API allows you to send and receive text messages as well as tracking the delivery of the messages you have sent. You can also retrieve your SMS message history by accessing comprehensive SMS delivery reports.
Your free SMS API account comes with 50 free text credits for testing. Our copy and paste code snippets in your chosen programming language mean you’ll be up and running in no time.
We'll provide you a unique reply phone number, free, for life . This will allow recipients to reply to the texts they receive.
The virtual mobile number is not shared with other users but is unique to you. Other SMS API providers charge as much as £15 a month for each reply number.
Replies are routed to a URL that you specify in your account. Incoming texts can also be sent to you via email. Free keyword on our shortcode 88440 keyword on a shortcode allows you to add a text response option to your marketing channels, e.g. Text INFO to 88440 to receive a discount voucher. Incoming texts are sent to a set URL and or email.
New customers buying 500 SMS credits or more will receive an additional 500 credits completely free of charge.
This means that your first purchase could cost as little as 1.45 pence + VAT per text.
We're here to provide you with as much support as you need to get up and running with our SMS API. We expect to handle all our support requests within the hour.
SMS API Pricing has dropped by 63% since 2001.
Our latest research reveals that 20 years ago it cost about 9.7 pence to send a business SMS to a mobile number. In 2020, it costs around 3.5 pence.
That’s an astonishing drop. In almost all cases, SMS providers simply aren't passing on the price reduction to customers.
Also, paying for undelivered texts when your existing provider doesn’t, isn’t a very open way of operating.
By looking at your SMS delivery reports you’ll be able to see how much you’re currently spending on failed texts.
Over the course of a year, it’s likely to be a reasonable amount. Our delivered only pricing means you only pay for what’s delivered so there zero wastage.
