The mobile phone number has not been used for two years. Will it be taken back?

I have the same experience as you. It's been 1 year for 2 months, and it's useless and has not been paid ~ it's a trip to Shenzhou. When I went to the mobile business hall for consultation, I got the answer that I would not pay the fee for 3 months and the number would be automatically recovered. But a few days later, my classmate called me to say that it was down, but it was not available. I went to the mobile hall to check whether the owner of this number was still me, and the answer was still my name.
