Send SMS messages globally, either individually or as a batch. All undelivered texts are refunded.

Receive SMS

Use our virtual mobile numbers or keywords on our 88440 shortcode to receive incoming SMS. Texts are forwarded to your email or webhooks.

Set Dynamic Sender IDs

Choose your own alphanumeric originator (who the message is from). No restrictions and no need to register the sender ID in advance.

Use tags to label your messages

Tags & metadata can be added to your texts to define customer accounts, cost centres, etc. Stored on your delivery reports for analysis.

Send Longer Messages

Send messages up to 1280 characters in length. Emojis and new lines are supported too.

SMS OTP Platform

Increase security of sign-up forms and transactions by using our complete SMS OTP service.

Cost Effective

We've thought carefully about how we can help save you money and designed our services around it.

Undelivered Texts Refunded

We'll add the credits used on messages that can't be delivered back to your account. Zero wastage SMS.

Use SMS Auto top-up so that you never run out of credits.

AI Message Optimisation

Our AI message optimiser uses Chat-GPT to shorten messages that are just over the SMS character limit, so that you can communicate clearly without overspending.

Unicode & Emoji Character Replacement

Automatic replacement of common unicode characters with their GSM equivalents (e.g unicode hyphens and apostrophes), which otherwise reduces the number of available characters from 160 to just 70 per message.

Auto SLM Ltd

"We initially moved to The SMS Works due to the great value package they offer, both in overall cost and not charging for undelivered texts. Over the last year we have found their support to be excellent, nothing is too much trouble and their response time is very impressive. Their developers have worked closely with us to provide a robust implementation of their service for our own B2B customer base."
