You’ve booked your flights, planned your itinerary, and are dreaming of your next adventure. But before you purchase a travel eSIM to stay connected, there’s one critical 30-second check you must perform: ensuring your phone is unlocked. A carrier-locked phone is the number one reason travelers can’t use an international eSIM, potentially leaving them stuck with exorbitant roaming charges.

Don’t let a simple setting derail your trip. This 2025 visual guide will walk you through the easy steps to confirm your phone’s status. Once you get the green light, the world of affordable, flexible data is yours with Yoho Mobile’s global eSIM plans.

What Does a ‘Carrier-Locked’ Phone Mean?

A carrier-locked (or SIM-locked) phone is a device that is restricted to work only on one specific carrier’s network. This is common for phones purchased through a financing plan or as part of a contract from providers like AT&T, Verizon, or T-Mobile. The lock is a software code that prevents you from using a SIM card or eSIM from any other operator.

For international travel, this is a major hurdle. A locked phone won’t be able to activate a local or regional eSIM, forcing you to rely on your home carrier’s expensive international roaming packages. An unlocked phone, however, gives you the freedom to choose any provider, saving you money and hassle.

How to Check if Your iPhone is Unlocked for eSIM

Apple makes it incredibly simple to verify your iPhone’s SIM lock status. This is the most definitive way to know if you’re ready for an eSIM.

Here’s the 30-second check:

  1. Open the Settings app.
  2. Tap on General, then tap About.
  3. Scroll down to the bottom of the page and look for the Carrier Lock field.

If it says “No SIM restrictions,” congratulations! Your iPhone is unlocked and ready for a Yoho Mobile eSIM. You can stop here and start browsing data plans.

If it lists a carrier name, your phone is locked. You’ll need to contact that carrier to request an unlock before you can use another provider’s eSIM.

How to Check if Your Android Phone is Unlocked for eSIM

Checking the lock status on an Android device can vary slightly between manufacturers like Samsung, Google, and others. However, the most common method is to check if your phone gives you the option to add an eSIM.

Here’s the general process:

  1. Open Settings.
  2. Go to Network & internet or Connections.
  3. Tap on SIMs or SIM card manager.
  4. Look for an option like “Add eSIM,” “Add mobile plan,” or a “+” icon.

If you see this option, your phone is almost certainly unlocked and eSIM-compatible. The presence of the feature to add another carrier’s plan is a strong indicator of its unlocked status.

If you can’t find this option, your phone might either be locked or not support eSIM technology. It’s a good idea to double-check our official eSIM compatible devices list to confirm your model’s capabilities.

What Should You Do if Your Phone is Locked?

Discovering your phone is locked isn’t the end of the road, but it requires action before your trip. The only way to unlock it is to contact the original carrier that the phone is locked to. Each carrier has its own set of requirements, which usually include:

  • The device must not be reported as lost or stolen.
  • The contract or financing plan for the device must be fully paid off.
  • The account associated with the device must be in good standing.

Visit your carrier’s website (like this unlocking policy page from Verizon for an example) or call their customer service line to initiate the unlocking process. Do this well in advance of your travels, as it can sometimes take a few days.

Frequently Asked Questions (FAQ)

Q1: Can I use an eSIM if my phone is locked?

No. A carrier-locked phone will not allow you to activate an eSIM from a different provider. You must first have the phone unlocked by the original carrier to use a travel eSIM like those from Yoho Mobile.

Q2: What does ‘No SIM restrictions’ on an iPhone mean?

This is the clearest confirmation that your iPhone is factory unlocked. It means you are free to use a SIM card or an eSIM from any compatible carrier in the world, making it perfect for international travel.

Q3: How do I unlock my phone for international travel?

You must contact the mobile carrier you originally purchased your phone from. Fulfill their requirements, such as paying off the device, and request a ‘carrier unlock.’ Once they process it, your phone will be able to accept foreign SIMs and eSIMs.

Q4: Will checking my SIM lock status affect my phone’s warranty or data?

Not at all. Checking the SIM lock status is a completely safe, non-invasive process. It’s like looking up a file on your device; it doesn’t change any settings, delete data, or void your warranty.
