The Verizon iPhone 5s is unlocked and thanks to support for multiple LTE bands it will work on other carriers including AT&T, which makes it an attractive option for users who need multiple carriers to deliver the best service while traveling.
It’s also a good option for users who might want to buy an off contract iPhone 5s to use on a pre-paid service like Straight Talk, which should work on the Verizon iPhone 5s as well.
As we explained soon after Apple’s iPhone 5s announcement while you can’t use the Verizon iPhone 5s on Sprint, you can use it on AT&T or T-Mobile networks in the U.S.
When we purchased the iPhone 5s the contract made it sound like the Verizon iPhone 5s is locked, stating that it may not work on other wireless carriers even after the contract is over, but we are able to use the Verizon iPhone 5s on AT&T by simply swapping SIM cards.
Verizon iPhone 5s Unlocked – Swap to AT&T Video
As the video above shows it is easy to switch back and forth between AT&T and Verizon on this Verizon iPhone 5s. The process does not require users change any settings, ask Verizon to unlock the iPhone 5s or necessitate a jailbreak or other hack.
Just swap SIM cards and you are good to go. iMessage will prompt to use the new number for iMessage and FaceTime, but that’s the only action users need to take. When the new SIM is in place the Verizon iPhone 5s will use the number associated with that SIM.
The iPhone 5s uses a nano-SIM card, like the iPhone 5, so some users will need to cut it down to fit and use an adapter in their other phone. The Moto X also uses a nano-SIM so it is a perfect option for swapping between phones.
In the video we only see AT&T 4G coverage, but that’s because AT&T LTE is not available here yet. In areas where AT&T 4G LTE coverage is available, the Verizon iPhone 5s can connect to it when paired with a compatible AT&T SIM card.
After testing this, the iPhone 5s switched back to Verizon as soon as the correct SIM was put in place. The only lingering issue is a new phone number that shows up on the iMessage list, so if you try this as a test, you may want to say no to using the phone number with iMessage.
