How to Unlock Your Phone & Use it With a New Carrier

Last Updated:

Do you know how to unlock your phone? Well, if you're interested in a bring your own phone plan, you'll find that you need to make sure you can activate it with another carrier.

This won't be possible if your phone is locked, according to the FCC.

These days, it is completely legal to unlock your mobile phone and bring it to another carrier; but it wasn't always this way. Consequently, this article is a guide for you to free your locked phone from its previous carrier network.

Since the unlock process differs for each carrier, I have summarized how to unlock a cell phone using each major network provider.


Up until 2014, public-law stated that it was illegal to unlock your cell phone without your carrier's permission, according to CBS News. At this time, the Unlocking Consumer Choice and Wireless Competition Act was signed by President Obama. As stated by, the act repealed the law so that consumers are now free to unlock their old or used mobile phones and use them with other carriers.

Now that it's legal, most cell phone carriers will allow customers to buy used cell phones or use their old phone to activate a plan on their carrier network (This is called a BYOP Plan). This means more cell phones are being recycled and people are paying less for their plans. Consequently, many people are wondering how to unlock a cell phone, especially since many bring your own phone plans require your phones to be unlocked.

CDMA vs. GSM Networks

The CDMA network and GSM network are the two different types of cell phone networks with two different cell phone unlock procedures. Sprint and Verizon use CDMA while AT&T and T-Mobile use GSM. Here's the difference between the two.

GSM Network

GSM stands for Global System for Mobile Communication. With a phone from a GSM network, all you'll need is a PUK code (Personal Unlocking Key) to unlock your SIM card on your device. As I said, AT&T and T-mobile both have phones with GSM SIM cards you can unlock.

CDMA Network

CDMA stands for Code Division Multiple Access. If you want to unlock iPhones, Androids, or other phones from a CDMA network, the phone needs to be reprogrammed in order to be unlocked. You can call your carrier for help with this.

Factory Unlocked Phones vs. Unlocked Phones

When trying to implement a cell phone unlock on a GSM SIM card for a phone, you may come across two types of unlocking: factory unlocking and regular unlocking. Factory unlocked phones are different from unlocked phones for one reason: they have been unlocked by the phone's carrier instead of by a third party.

Pro Tip: If you want to do a hard reset or factory reset to clean out your phone, do it before you unlock the phone. If you complete a hard reset or factory reset after unlocking your phone, the reset could re-lock it.

What You'll Need

If you want to know how to unlock your phone, you'll have to get some things together. Here's what you'll need:


IMEI stands for International Mobile Equipment Identity. Ultimately, the IMEI of your iPhone, Windows, or Android device is your cell phone's unique identity number. You need it to unlock your phone.

To find it, try dialing the code *#06#. Your IMEI number should then appear on your mobile phone. If not, it may also be located in the battery compartment.

Finding your iPhone's IMEI

An iPhone's IMEI may be located in a different spot than other phones. If you need the IMEI number on your iPhone, Apple iPhone has an entire page dedicated to finding it on your specific Apple device.

2. Phone Number

You will need to provide your phone's number to unlock it.

3. Full name of account holder

You will also need to know the full name of the account holder. If you want to unlock a used phone, ask if the network provider will unlock it without an account.

4. Account number and pin or password.

You'll need the account number and password to unlock your cell phone. If you don't have an account, call to make sure they will allow you to switch to their network.

Unlocking a Phone via Carrier Network

Once you've collected your information, call the service provider you are switching to and make sure your phone will work with their network. It doesn't matter whether you have an Android phone, Apple iPhone, or Windows phone, but your network provider is important.

Additionally, the phone's previous carrier is important. Different providers connect via different networks. Therefore, you need to make sure your phone will work fully before you switch. Apple details iPhone unlock directions on their website to unlock the iPhone.

Unfortunately, unlocking a phone is different for each major service provider including AT&T, Verizon, Sprint, T-Mobile, or Metro PCS. Read on to discover how to unlock iPhones, Android devices, and Windows devices on any of these networks.

How to Unlock a Verizon Phone

  • Your phone cannot be reported lost, stolen or associated with fraud.

1. Postpaid plan policies and instructions

  • If you purchase a postpaid plan with Verizon, it's likely your phone won't be locked. If you have or buy used 4G LTE cell phones from Verizon, your SIM cards will definitely not be locked. You should not need a SIM unlock code to activate your phone with another network as long as you meet the requirements above.
  • Verizon does lock non-iPhone, 3G World Device SIM cards that have been activated with a postpaid plan. If you have an older phone that's not an iPhone, the PUK code to unlock is either "000000" or "123456." The user guide for your phone should direct you to the phone's programming menu where you can input the SIM unlock code.
  • If you have any questions or cannot find your phone's user guide, call Verizon for help at this number: (800)-922-0204. You can also contact them using *611. They will unlock your phone for you if you ask them.

The minimum payment amount is usually specified on the back of your Phone-in-a-box package.
  • Once you have either made the payments or waited a year, the code to unlock your phone is also either "000000" or "123456." Verizon will help you unlock it at your request.

  • Once your time is up, the code to unlock your phone is the same as above. Contact Verizon with any questions.

How to Unlock a Sprint Phone

Not all phones are capable of being unlocked under a Sprint cell phone plan.

Additionally, even after your phone undergoes a Sprint unlock, it may not work fully with another carrier. If you want to unlock your Sprint Network cell phone, you have to call them and ask. Here are the Sprint network's policies regarding locked phones.

  • They can only Sprint unlock your phone if your SIM card is capable.
  • They will only unlock your SIM card if your cell phone has been active with Sprint for at least 50-days.
  • All payments and agreements must be completely settled before Sprint will consider unlocking your phone.
  • Sprint will not unlock a phone that has been reported lost or stolen.

If you meet all of these requirements, Sprint will happily unlock your phone for you. They even sell SIM unlockable devices now. If you purchased a new phone from them after February 2015, they will unlock it automatically as soon as it becomes eligible. You can call their customer care number at (817)-698-4199 with any questions.

Additionally, if your cell phone has been inactive for a while, it may take Sprint a little while to get it unlocked. They will sometimes have you update the phone "over-the-air" to ensure the unlock programming has been transmitted to your cell phone. SIMilar to Verizon, they cannot guarantee that your phone will work with another carrier once it is unlocked.
