Most phone numbers are eligible to be brought to Verizon*, but some numbers may not be eligible based on geography, service area coverage, technology, or ownership of the line you're transferring from. You can always check your eligibility before you switch to Verizon.

*Local Number Portability, a government mandate, requires mobile and landline service providers to let customers keep their eligible phone numbers when switching carriers.

To unlock your AT&T phone, there are some requirements you should be aware of. Your device must be:

• Paid off.
• Not associated with another active AT&T account.
• Not reported as lost, stolen, or involved with fraud.

You also have to be sure to not have a past-due account balance with AT&T in order to fully unlock your device.

Once you meet these requirements, you can submit a "Device Unlock" request via AT&T's website, or one of our retail representatives can assist you if you're visiting us in-store.

For a phone locked to T-Mobile's network, first make sure your phone is eligible for unlocking, then follow these steps:

• Make sure you are connected to your wireless network or Wi-Fi.
• For Android phones, you can typically find a "device unlock" or "network unlock" option in Settings.
• For Apple phones, simply contact T-Mobile and request that they unlock the device.

For other carriers and brands, you should call your mobile provider for guidance.
