I currently have an iPhone 5S with AT&T. I would like to try T-Mobile without porting my current number but in such a way as my friends and contacts see my current AT&T number, not the new T-Mobile number. Having tried it, it I like T-Mobile, then I will port my old number.
But in the meantime, I don't want to confuse friends and contacts that my number has changed then possibly changing back to the old number. This should really be a thing to help you evaluate a new service.
I think that I can forward calls to my old number to the new number using Settings->Phone->Call Forwarding.
But how do I make it so that when I call or send a text (or iMessage) that it appears to be coming from my old number?
