I try to upgrade one number but I create one now contract,how I need to cancel one?
Welcome to the community,
I would suggest you ring customer service to sort this out, as when you upgrade your number should automatically move over with your upgrade. You had better make sure that you did not start a new contract and that it was an upgrade.
One of these options may help you find the answers you need.
