Is it possible to have a standard SIM & also a Micro SIM both with the same number so I can continue to use my old HTC. Only one phone will be in use on the cell network at any given time?

Micro sim with…

…and swap the sim. Can’t imagine its possible to have two SIMs with same number

Thanks – Hmmm didn’t want to be constantly swapping sim card, I imagine it would soon cause wear to the phones contacts. There must be a snide way of achieving this 🙄

Technically possible, it was a feature on O2 but I believe it was only sold to business customers. I seem to remember it was called dual IMSI.

I suspect you wont get any operator to offer it to a consumer though, not when they can make you buy two subscriptions instead….
