Hey there ​@neatsm, unfortunately, you cannot transfer your phone number directly from one iD Mobile contract to another. The only way to directly keep your number would be to upgrade or plan change via your account on the iD Mobile app/website. The only alternative is to compelte a triangle port, which is explained below:

1) Get a PAC code for the number you wish to keep.

2) Purchase a Pay As You Go (PAYG) SIM from any OTHER network.

3) Give your PAC code to the new PAYG SIM provider to transfer your number from iD Mobile to the PAYG network.

4) Once it's been transferred over, this sends your number to the new network on PAYG and cancels your old contract with us automatically, the final bill will be sent via email.

5) Once the number has fully transferred to the PAYG network allow 24 hours and then request a PAC code from them.

6) Transfer your number to the new iD Mobile plan via PAC code at the link below, once the transfer is fully complete your PAYG SIM will be disconnected and the desired number will be on the new iD Mobile account.

Note; With a new iD Mobile account, you'll need to register a new iD Mobile app/website account to using an email address that hasn't been used previously to register.

Thanks,
