A Premium SMS text is a subscription service provided by premium service providers. 

If you think you are receiving a text message in error – or you no longer want to receive a premium SMS – then it is relatively easy to stop getting these premium SMS messages on your phone.

1. Text “STOP”

Under most countries’ regulations, all providers of premium SMS must provide clear information on how to stop receiving these text messages.  In most cases, text “STOP” to the number that sent you the premium SMS, and you shouldn’t receive any more premium texts from them.

This works in the majority of cases, but

2. If this does not work

If you have an iPhone, you can block text messages from any number in the Messages app on your mobile device

If you have an Android phone, you can disable access to premium SMS in the settings on your mobile device
