Ok. Here goes
I was with a provider with a sim (henceforth to be refered to as sim 1). They offered a better contract but I couldn't upgrade to it for some reason. So I bought a new sim on that contract and used it (sim 2)
I then realize I can't keep my number if I get another SIM from the same provider.
So I then realized I could 'triangulate'. So I got a free gift gaff sim (sim 3)
My plan was to go to giff gaff then come back and be able to keep my original number on the improved plan.
But now my head hurts and I don't know how to do it.
Currently I have sim 1 in a box. Sim 2 in the phone. Sim 3 yet to be used.
Help?!?! I'm currently paying the 2nd contract price and would like to stick but get back to my old number.
