You can get a roaming deal on that number, at some cost.

Another option is to look into eSIMs. I was interested in Saily from Nord but it turned out they do not (yet) offer a phone number. I believe other companies do. I haven't pursued it because like Mendip I keep a live UK SIM as well as my Thai SIM and since I seldom travel now this works for me.
