My 24 month contract ends next month and I can upgrade from now. I don’t want to upgrade. However I do want to go onto a monthly rolling sim only deal. I’ve seen a deal online for £12/m for new customers.
1.) how do I arrange to switch to sim only?
2.) will I receive a new sim and do I have to arrange for to keep my current phone number?
3.) do I need to give notice now to leave my current contract?
