Business SMS – A changing industry

SMS Gateway prices in the UK have fallen by over 50% in the past decade or so. It wasn’t too long ago that you could expect to pay around 10 pence per credit for a small bundle of texts.

As prices have reduced, so the number of potential providers has also rocketed. 
There must be well over 50 potential UK SMS gateway providers now compared to a dozen or so at the turn of the millennium.

So while there’s more choice and at a lower price, there’s one SMS pricing oddity that’s remained resolutely resistant to change.

Users of SMS services typically have to pay for messages that are not delivered, while the providers themselves are not charged. So there’s a built in additional profit for the SMS provider.

This model is now being challenged by The SMS Works who are one of very few providers that refund credits for messages that have not landed on the handset.

It’s a far more open and fair approach that’s becoming increasingly popular as customers start to challenge the status quo.

Set up a free SMS API account with 50 free text credits and you’ll be sending through our SMS API in no time.
