To keep, port, your number, go to a provider and tell them to port your existing to your new account.

If you have a phone with a compatible SIM, just swap the SIM into the new phone, no port is needed...

If you’re switching carriers from GSM networks like AT&T to T-Mobile, things are easier. Once your phone and any outstanding fees are paid, you are free to take your GSM network phone and bring it to any other GSM carrier. In this scenario, customers think they're paying for their phone itself but in reality you're also paying for the SIM card and all of the data on it. Now the SIM card is officially unlocked and you have your phone number and data all ready for a brand new carrier (or new phone if that’s the case).
And while halux is correct, carrier and security system updates can be missed if not careful.
Edit :need to be unlocked

If you have a phone with a compatible SIM, just swap the SIM into the new phone, no port is needed...

It should also be noted that if the old phone number is no longer yours, it may have been recycled to a new user.

Good point. If you give up your number in a crowded area code, it can be gone almost immediately. Make sure your transition is seamless.
