How to Switch Cell Phone Carriers Without Losing Your Number

Switching phone carriers can save you $50-$100 or more per month. Here's how to compare plans, keep your phone number, and make the change smoothly.

In this guide (4 steps):

1.Compare plans before you switch
2.Do NOT cancel your old service before switching
3.Gather what you need to switch
4.Activate your new SIM and confirm everything works

Compare plans before you switch

~36s

Common options worth comparing: T-Mobile Essentials 55+ (two lines, special senior pricing), AT&T Value Plus 55+, Consumer Cellular (AARP partner, no contracts, widely recommended for seniors), Mint Mobile (T-Mobile network, very low cost, pay monthly or upfront), Visible (Verizon network, $25-$30/month unlimited). For the best deals, search AARP Wireless Partners or compare plans on the AARP cell phone plan comparison tool. Check coverage in your area by entering your zip code on each carrier's website before switching.

Quick Tip

Quick Tip: If you don't use much data (only check email, browse Facebook, and occasionally use maps), a 5GB or 10GB plan may be all you need and will cost significantly less than unlimited.

Do NOT cancel your old service before switching

~32s

This is the most important rule of switching carriers. Do not cancel your current plan until your new carrier has activated your service and ported your number. Canceling first causes your number to be released, which makes it much harder to transfer. Instead, start the switch with the new carrier — they will handle contacting your old carrier and initiating the number transfer.

Warning

If you have a contract with your current carrier, check if an early termination fee applies. Many carriers now offer no-contract plans, so this is less common, but worth confirming before you switch.

Gather what you need to switch

~33s

To port your number you'll need: your current account number (found on your phone bill or in your carrier's account page), your account PIN or password (set when you created your account), your current billing address, and your phone's IMEI number (a unique device ID — dial *#06# to see it). Have these ready when signing up with the new carrier.

Quick Tip

Quick Tip: The number transfer (porting) usually takes 1-2 hours but can take up to 24 hours. During that window, calls and texts may be disrupted briefly. Plan your switch for a day when you don't have critical calls expected.

Activate your new SIM and confirm everything works

~25s

The new carrier will send you a SIM card (or an eSIM activation code). Insert the SIM or follow eSIM activation steps. Your new carrier's app or website will walk you through activation. Once active, test making a call and sending a text. After 24 hours, confirm your old service has been canceled automatically (it should be — the port process cancels it). Contact your old carrier to confirm no more charges will appear.

Phone plans have changed dramatically in recent years. Many carriers now offer plans specifically designed for people 55 and older, and smaller "virtual" carriers (called MVNOs) often use the same towers as Verizon, AT&T, or T-Mobile but charge 40-70% less per month.

Switching your cell phone carrier sounds intimidating, but it is a routine process that happens thousands of times a day. Your phone number is yours — it belongs to you, not the carrier — and you have the legal right to take it with you when you switch. This is called "porting" your number.

Before switching, make sure your phone is unlocked (not tied to your current carrier). Most phones are automatically unlocked after they are paid off, or after 12 months of service. You can call your current carrier to confirm.
