Cancelling a mobile data SIM contract

[swampmonkey]

How do I cancel a mobile data SIM contract?  I have never used it and my contract ended on 8th July.  I am overseas, so if I call the Vodafone support number - 191 - will I be charged?  Thanks!

Hi @swampmonkey 

Have you considered cancelling the data contract using a STAC code (service termination authorisation code) ?

If the device you are using does not send texts, insert the data SIM into a phone and text STAC to 75075 you will receive a reply with a STAC relevant to the data SIM number.

If you know someone in the UK on any other network, ask them to submit the STAC to their network and the data SIM will immediately end without the need to contact Vodafone and waste time trying to speak to a human and generate the final billing.  Asking someone to submit a STAC won't affect the account of the person submitting the STAC.

Thanks.  Very interesting.  I'll try to deal with a human at Vodafone,  but if that doesn't work I'll use your plan as a fallback.
