One of the hottest topics of the moment for the US wireless industry is device unlock policies, or SIM unlock policies. With verizon getting a waiver from the FCC to implement whatever unlock policy it would like, it’s probably a good idea that everyone knows what their carrier’s requirements are for unlocking a device.
Below, we’ll run through the three major US carriers and each of their policies. Keep in mind that each carrier also has several sub-brands, MVNOs, or prepaid providers they own that might have different policies. These are the official policies if you were to purchase service directly from T-Mobile, AT&T, or Verizon.
What is a SIM unlock?
For those entirely unfamiliar with all of this talk about unlocking phones, let’s back up for a minute. When someone buys a phone from a carrier, those phones are device or SIM locked to that carrier’s network. Should you buy a Pixel 10 Pro or iPhone 17 Pro from T-mobile, such as, you couldn’t immediatly take that phone and then use it on AT&T’s network.

By giving you a deal on a new phone, they expect you to remain a customer for a while and pay for a monthly bill, which is how they make so much of their money.
As the world understands that you shouldn’t be forever locked to one single carrier with your device, carriers have adopted unlock policies that allow you to free a phone from their network and use it elsewhere. Again, this often only happens once several requirements are met.
There are also different unlock policies for postpaid and prepaid plans, with postpaid being the type of service you likely have as postpaid plans are those that get you device upgrades and device payment plans for very cheap.
on the flip side of all of this, you could buy a phone that is already unlocked and not have to deal with any of the unlocking business. Buying phones directly from samsung, Google, and Apple will get you phones that are unlocked and have no requirements for unlocking – they just work on all carriers out of the box. Those phones frequently enough require you to pay full price, though, thus the rea
