How To Switch Phone Carriers and Keep Your Number

‍

Thinking about switching phone carriers? The good news is that it's a fairly straightforward process, and you can even keep your current phone number when you do it.

Major carriers (AT&T, Verizon, T-Mobile) smaller prepaid carriers (Mint Mobile, Visible, Boost Mobile, etc.) alike are highly motivated to get you to join their networks, so switching can entitle you to some amazing plan and device savings—you may even be eligible for a free phone.

Read on as we detail the process for switching phone carriers, and flag some important details you'll want to keep in mind as you undertake the process.

How To Switch Phone Carriers

When you decide you are ready to switch carriers, you need to go through the following steps:

1. Check if your phone is unlocked. This will allow you to use your phone with other carriers.
2. Check in your settings to see if your phone can use multiple networks. If not, contact your existing carrier to have them perform the unlocking process.
3. Choose to either get a new phone or have your old phone connected to the new plan. Most carriers like AT&T, T-Mobile, and Verizon offer cell phone deals for switching carriers.
4. If you want to keep your old phone, check with your new carrier about how to get it set up. This may include backups to ensure your data makes it through the switch.

At this point, you will be clear to set up service with your new service provider. Note that your new carrier and your old carrier are the ones doing the work now, so you just provide your old account number and details and wait for them to complete the transfer process. You’ll want to watch out for any early termination fees (ETFs), which many carriers offer to pay off on your behalf in addition to your outstanding balance on your old plan.

Why Should You Switch Carriers?

There are a variety of reasons switching cell phone carriers can make a lot of sense.

1. Coverage: Depending on where you live, one carrier may offer better coverage than another. Check out our coverage maps to figure out which telco gives you the best 4G and 5G coverage in the places you spend time.
2. Better (or cheaper) plans: Competition is fierce in the cell phone market, with carriers constantly updating their plan offerings in an effort to attract more customers. As a consumer, switching carriers can allow you to tap into better plan features from competing carriers.
3. Phone deals: Many wireless providers offer deals on mobile phones, hotspot coverage, or unlimited data plans that only go through if you sign up for their service. The best deals typically target those who switch to their service from another carrier, directly targeting customers who are not currently utilizing their network. 
4. Better perks: Every carrier has different perks to go along with its cell phone plans. The perks being offered by a particular carrier may be attractive to compel you to make the switch.
5. Cheaper prices: Some carriers simply offer more competitive pricing than others. This is particularly true of smaller carriers like Spectrum Mobile, Xfinity Mobile, and other MVNOs. Switching to cheaper carriers and plans allows you tap into instant savings on your cell phone bill.

Locked Vs. Unlocked Phones

When you get a phone from a carrier versus a retailer directly, you might be getting a slightly different type of product. Carriers will usually sell you a locked phone, while manufacturers will usually sell an unlocked phone.

Locked Phones

In short, a locked phone is a device that is specifically tied to a particular carrier. If you buy an iPhone from Verizon, for example, you won’t be able to use your phone with any other networks other than Verizon’s. 

A locked phone has a software code integrated into it that prevents use with any carrier other than the carrier that you bought the phone from. If you reach a point where you would like to unlock your phone or switch providers in general, then you need to coordinate this with your carrier before that can happen.

Unlocked Phones

An unlocked phone is a phone that has no ties to any carrier, and can be used with any network without having to make any software changes. Unlocked phones have become popular around the world for a variety of reasons, not least being phone compatibility. 

For example, with an unlocked phone, you can easily swap SIM cards when you travel and use your phone with overseas networks. Plus, unlocked phones make switching providers much simpler. Unlocked phones are also worth more on the resale market, as there are fewer hoops that a buyer has to go through to get it working with their carrier. 

Overall, unlocked phones give the consumer more options and less hassle. However, that does not mean that someone with a locked phone is stuck with their provider indefinitely.

How to Switch Phone Carriers and Keep Your Number

It's easy to switch phone carriers and keep your number—referred to as porting.

In order to do this, you need to put in a porting request with your new carrier. Many carriers will offer the porting process as a part of their unlocking and switching process, but check in with them first to be sure.

If you do not do this, it would be possible to have the same phone but with a new phone number and completely different SIM information.

How to Switch Phone Carriers and Keep Your Phone

Not interested in new phone deals? If you want to save money, or you love your existing cell phone, keeping your existing phone while switching carriers is appealing. Here’s how:

1. Check Compatibility: Not all phones work with all carriers due to differing network technologies and frequency bands.  In general, most carriers offer a simple online tool where you can input your phone’s IMEI number (a unique identifier) to check compatibility. 
2. Unlock Your Phone: If your phone is paid off and your account is in good standing, carriers are legally required to unlock your phone upon request, if they haven’t already done so.
3. Get a New SIM Card: Once your phone is unlocked and compatible with the new carrier's network, you'll need a new SIM card. Make sure to ask about transferring your current phone number as well; most people want to keep their number, and carriers can transfer it over, known as "porting."
4. Backup and Transfer: Whether it's to the cloud or your computer, ensure your data is safe. Once you have your new SIM and are ready to activate your new service, follow the new carrier's instructions for setting up your phone.
5. Test : Make calls, send texts, use data, and ensure everything works as expected. If there are issues, don't hesitate to contact your new carrier's customer service.

The Bottom Line

Switching carriers is an easy process, but you need to make sure you do it right. Check in to see if you have a locked phone or an unlocked phone, as this has a big impact on how the transfer works.

When making the switch, following proper procedure is important to ensure your phone and all its data are able to make it over. However, if you want to get a new phone, then switching to a new carrier and plan often does come with a lot of interesting perks to reduce the cost of your new phone.

Frequently Asked Questions

Is switching phone carriers an easy process?

Yes, changing cell phone carriers is surprisingly simple. Typically, you pick a new plan and contact the new carrier, and their customer service team will handle everything from there.

Do you need to back up your phone before switching carriers?

No, you don't need to back up your phone before you switch carriers. Switching carriers won't affect the data stored on your phone since it's all saved directly to your device. However, you won't be able to take your phone to a new carrier if it's a locked device. Still, it's a good idea to back up your data if you're getting a new phone or just for peace of mind.

Do I have to pay my phone bill before switching carriers?

Before switching carriers, you'll need to pay off any remaining balance on your phone. Be sure to also check for any early termination fees. Sometimes, your new carrier might offer to cover those costs as part of a promotion, so it's worth confirming with your current and new provider.
