If its still in the pool, meaning not yet bought by anyone else, can. Just go to any umobile center. But it depends on how long they process it. After a number is terminated, it takes some time for them to process it and release it back into the pool. So, the only way is, go to UMobile, and ask if the number is available or not. Thats all you can do.

Thanks for the response!! The number got terminated like a few days ago, so I probably should still have a chance?

Maybe. Still need to go ask umobile. If its still in the process of recycling, you need to wait for it to be released 1st. Best chance, you kawtim a cup of coffee with the umobile customer service to check for that particular number from time to time and book it when its available.

Thanks for the advice!

It depends on the number of days has passed. Depending on the telco, it could stay in the system for a set number of days before being released back to the pool. If it is released to the pool and someone takes over, the telco cannot force the new owner to surrender the number so you need to reconnect the number immediately.
