If you’re thinking of switching your cell phone carrier, there are a few things you need to do first. First, unlock your phone if it’s locked to your current carrier. Next, find out if your phone is compatible with the new carrier. Finally, sign up for a new account and activate your phone. Here’s how to do each step:
- Unlock Your Phone If It’s Locked to Your Current Carrier To unlock your phone if it’s locked to your current carrier, you’ll need the original lock code and the current provider’s SIM card. You can find these codes online or from your previous provider. Once you have these codes, enter them into your phone’s unlock screen and press “unlock.”
- Find Out If Your Phone Is Compatible with the New Carrier If you’re thinking of switching carriers, make sure your phone is compatible with the new one first. To check if your phone is compatible, go to the manufacturer’s website or contact customer service for the new carrier. They will be able to tell you if your model is supported and provide instructions on how to activate it on their network.

Most cell phones sold in North America—especially on contract—are “locked” to a particular cellular carrier. You can only use them on that carrier’s network, so you can’t switch to another carrier without “unlocking” the phone first.

Phone locking applies to nearly any type of cell phone, from the lowest, cheapest dumb phone to the highest end smartphone. Unlocking is different from jailbreaking and rooting, which bypass other software restrictions on mobile devices.
Unlocking Won’t Make Phones Completely Portable
First, it’s important to bear in mind that phones won’t always be capable of working on another carrier even after they’re unlocked. For example, in the USA, AT&T and T-Mobile use the GSM wireless standard, while Verizon and Sprint use the CDMA wireless standard. These are incompatible with each other, which means that you can’t unlock a CDMA phone purchased on Verizon and take it to AT&T’s GSM network, or vice versa.
CDMA is also a more restrictive type of network—while you can unlock an AT&T phone and take it to T-Mobile, you can’t unlock a Verizon phone and take it to Sprint, as Sprint’s CDMA network will reject the phone.
Luckily, most of the world has chosen the less-restrictive GSM standard. Before you consider unlocking a phone and taking it to another carrier, ensure that your phone will actually be capable of functioning on that carrier’s network.
Phone Locking Explained
The CDMA/GSM difference is a legitimate technical barrier to moving phones between carriers. However, there are also artificial barriers. Carriers “lock” phones to make them only function on that carrier’s network.
For example, let’s say you walk into AT&T and pick up any smartphone on contract. That phone then functions on AT&T’s network, but if you try to place a T-Mobile SIM card into the phone and switch to T-Mobile’s network, the phone will reject the T-Mobile SIM card. There’s no legitimate technical reason for this—it’s compatible—but the AT&T phone is “locked” to AT&T’s network and only accepts AT&T SIM cards.
This artificial locking would also get in your way if you were travelling and wanted to use a local carrier in the country you were visiting rather than paying expensive roaming fees. Your locked phone would reject anything but an AT&T SIM card.
Why Are Phones Locked?
Cellular carriers argue that phone locking is a necessary part of their business. By locking phones they sell on contract, they’re able to keep customers on their network so they’ll continue paying their monthly bills. Remember, phones aren’t actually worth their on-contract prices—they’re subsidized. No phone is actually “free” and the latest iPhone actually costs more than $199, so the carrier needs to recover the cost of the on-contract phone over the lifetime of the contract. If consumers were able to take their phones to other networks, carriers argue that they would have difficulty recovering the price of the phone and their business model would take a hit.
In reality, this is a fairly silly argument. If you buy a phone on contract, you’re signing a two-year contract. If you want to take that phone to another carrier, you’d have to break your contract and pay an early termination fee or keep paying the monthly bill for the lifetime of the contract. This contractual obligation would still be binding even if the phone itself was sold unlocked and you took it to another carrier. Some smartphones may even be sold locked if you buy them from a carrier store at full price, without signing a contract, which shows how silly this argument is.

Cell phone locking is really just a way to create additional friction for average people switching carriers, encouraging them to stick with their current carrier instead of looking around for a better price. It’s one of the many horrible business practices carriers employ to gouge their customers.
Unlocking Your Phone
So you want to unlock your phone. Maybe your contract has expired and you want to switch to another carrier, maybe you’re visiting another country, or maybe you just want to pay an early termination fee and get out of your contract early.
There are several ways to unlock a phone:
Call and Ask Nicely: Call your carrier and ask nicely—if your contract has expired, most carriers (in the US, at least) will unlock your phone for you as long as you’ve paid off anything you owe on the phone. If you tell your carrier you’ll be travelling and want to use a SIM card from another country to save on roaming fees, they may also be willing to unlock your phone. They may charge a fee, but it’s worth a shot.

Unlock It Yourself: In the past, unlocking a cell phone without permission was illegal in the USA, thanks to the Digital Millenium Copyright Act. Fortunately, that has changed. Cell phone unlocking is now legal in the US. However, if you live in another country or are willing to be a rebel and flout a law everyone agrees should be changed, you can often unlock phones on your own without anyone’s permission. The exact process varies from phone to phone, so you’ll have to perform a web search and find instructions for your specific mobile phone.
Of course, not all phones are sold locked. Often, phones sold directly from the manufacturer instead of by a carrier come unlocked. You’ll generally have to pay full price to get an unlocked phone that you can move between carrier networks, as there’s no carrier to subsidize the phone’s full cost.
