Hi. Years ago I bought a Three data-only SIM for my ipad on a monthly rolling contract. I now wish to cancel the contract, but when I call Three I'm asked for the mobile number of the SIM. I don't know what it is and I know longer have the original packaging. Any suggestions how to find this number, or how to get through to Three without it?
You could try calling another mobile from that data sim. Put it in a Three compatible phone and then your number will then be displayed on the recipients phone and as long as they don’t answer it won’t cost you anything.
