The SMS Works
The SMS Works is a UK SMS API that charges only for delivered messages, with reply numbers, OTP, batch sends and webhooks, using direct UK network routes.
Overview
The SMS Works Ltd is a UK company that sells a pay-as-you-go SMS API. Its main difference is billing: credits for texts that fail to deliver are refunded to the account. It says UK messages go over tier one routes direct to UK networks and never over grey routes, and that its platform meets GDPR requirements.
