Can I get back an old number?

[sc]

About 4 years ago, I had a different three PAYG sim card, and used it for 2FA.

Unfortunately, I forgot to use it regularly, and it was deactivated after a year or so. I asked customer service at the time if it could be recovered, and they said no, it would have been recycled.

I still have that sim card, I was hoping the number might be recycled again, and if so could I claim it? Is this possible or should I throw it away?

Hey sc, 

Unfortunately, once a certain amount of time has passed, we can't recover a cancelled account or number.

We'd recommend reaching out the company in question to update the details they hold for you, so you can make use of the authentication process again.

The risk with a recycled number is getting calls for the previous owner.
