To unsubscribe from a premium rate subscription service (a service where there is a recurring charge), send a text to the short code number for the service.
Text the word STOP. Do not text any other words as it could result in you receiving even more texts.
Note that a standard network charge may apply for this text. Once you have texted the word STOP to the sender, you should be unsubscribed within 24 to 48 hours.
If you have deleted the number from whom you have received the text, contact your mobile network operator to get further information on the number and the premium rate service provider associated with that number.
