Contact you current provider (T-Mobile) and tell them that you are leaving and request the PUC code. Once you receive this give this to Orange when you decide to switch. Once the switch has been done your contract with T-Mobile will cease and your contract with Orange will begin.



Please note, once you request your PUC code from T-Mobile you have to make the switch within a month, or the code expires, and you will need to re-request it.How can i keep my mobile number when changing networks?
Ring t-mobile and ask them for a pac code, they will give it to you over the phone and text it to you. You then ring up Orange and tell them you have a pac code, give it to them and they will tell you how long it will be before your number is transferred, usually about 48 hours.
contact t-mobile advised them that u are changing networks and you require a PAC code. they will then give u this, contact orange and give them the PAC code they will give you a temporary number until your original number is transferred
Please be aware that it is a PAC code that you need from your current network supplier to then give it to your new network supplier
