Can I request a specific phone number?

I’m sure it’s asked before but I’m looking for an answer in 2026. I had an old with them. I gave it up in April 2025 and I’m looking to see if I can get either a pay as you go SIM or a small payment monthly contract and reclaim that number as I need it for text verification purposes. Is this possible?

The number is still valid and is no longer in use and has not been given to anyone else.
