Pros and Cons of an Unlocked Phone
Each carrier offers a limited number of (locked) phone models to use with its services. Purchasing an unlocked phone elsewhere (such as from a retailer or the phone manufacturer) expands the number of models you have access to for use with your provider. However, if you use a phone not provided by the carrier, you may not get all the services that are available from that carrier.
Your Carrier May Unlock Your Phone for You
Some carriers will unlock your phone, but usually only after certain conditions have been met, such as the phone being completely paid for. You might want to have this done if you want to sell your phone or switch carriers without having to buy a new one. Unlocked phones make it much easier to change your cellular service carrier while keeping the same phone. Each carrier has different rules and processes, so you’ll need to follow those carefully for your phone to qualify.
Unlocking a Smartphone Yourself
You can unlock a smartphone on your own, but you might need help since there are so many different rules to follow depending on the carrier involved. You can pay a third party to unlock your phone, but doing so may void any warranty you may have, or cause problems when you want to update the phone’s software. Research these issues with your carrier thoroughly before moving forward.
SIM Cards and eSIMs
A subscriber identity module (SIM) card is a tiny card in your phone that contains information tied to a specific mobile network. The SIM provides the device with its phone number, as well as its voice and data services. When you unlock your phone and switch carriers, you may need to get a new SIM from that carrier. Some smartphones, such as the iPhone XS, XS Max, and XR, don’t use SIM cards. Instead, they have an embedded SIM (eSIM) that eliminates the need for a separate card. To use this type of phone with a specific carrier, that carrier must support eSIM operation, and most major carriers do support it. With an eSIM, there’s no need to swap physical SIM cards when switching between carriers.
Using Unlocked Smartphones
As noted above, if you buy an unlocked smartphone, you’ll need a SIM to get service unless your device is equipped with an eSIM. Otherwise, there’s little difference between using an unlocked smartphone and a locked one, assuming the phone was unlocked by a carrier or was purchased unlocked. Smartphones unlocked by a third party can be trickier to use because their warranties are likely void as a result of this action. Also, updates to your smartphone’s software can relock the phone, requiring you to unlock it again, an option that may not be available immediately after an update. Bottom line, buying and using an unlocked phone gives you more freedom to use your phone as you like, and it can save you money. But, before making your purchase, take time to do your research.
