Transferring your number to Birdie is easier than you think

Fed up with service bound by contract and wondering how Birdie can lift your mobile experience? Transferring your current mobile number to Birdie is easier than you think. Follow our guide step by step and you’re done in a snap!


Once you’ve successfully subscribed to Birdie’s mobile service, you don’t need to contact your current operator because we will work with them to settle everything else for you. Your mobile number will be carried over to Birdie on your chosen date.




Always remember to keep your number active throughout the transfer process. You don’t need to - and should not - ask your current operator to terminate your number’s service.




Monthly plan subscribers:Ensure you’re the number’s registered holder and your contract with the current operator has ended or is almost over (if you want to change the registered holder of your number, please see FAQ#12 under “Transfer My Number to Birdie”)

Prepaid SIM users:Ensure your prepaid SIM is active with a balance of at least HK$1.




It generally takes Birdie about 7 days to process the transfer of your mobile number, so you may subscribe to your new Birdie service 7 days prior to the end date of your current contract to have your number transferred to Birdie on the date your current contract expires.

You may also register up to 90 days in advance for a Birdie service subscription. Go through the registration, get your SIM, sit back and look forward to your service activation date.

*If you want to request for a different transfer date, email us at hello@birdie.com.hk after getting your SIM card.




We take great care of every customer request and the handling of your mobile number is no exception. Even if your number can’t be carried over to Birdie, it will remain with your current operator and won’t be lost.
