Switched number

I got a new phone on pay monthly with ID mobile through car phone warehouse. I asked to keep my old o2 number. It sent me a sim and when I put the sim in it gave me a new number for a few days then text me to tell me it was switched back to my old number. When I’m ringing people/ people are ringing me it’s coming up through my old number which is good. When people are texting my old number however it’s coming through my phone but when I text back it’s coming up as my new number ?

You can only retain your 02 number if you requested a PAC Code from 02; otherwise it’s likely reallocated.
