Use existing sim card in new unlocked phone

I recently purchased a new unlocked phone that is compatible with ATT; however, I don't know how to activate the phone after inserting the sim card (att). Do I need to deactivate the old phone before I can reactivate the number using my new phone? Seemed so simple, but it is turning into a nightmare. Thanks for any assistance.

Re: Use existing sim card in new unlocked phone

Typically if the SIM card form factor is the same all you have to do is move it from the old phone into the new one, no activation necessary. If the SIM card is of different size, it's best to visit a corporate AT&T store and exchange it for the correct size one. They'll activate it for you at the store then.

You don’t need to activate anything.  Just swap the SIM card and set up the new phone.  Often there is a mobile to mobile transfer option as soon as you turn the new phone on.
