Before you can use a Roamvy eSIM (or any eSIM provider), your phone must be unlocked. An unlocked phone can use mobile networks from any carrier, while a locked phone is restricted to the carrier you originally bought it from.

 

If you’re planning to check eSIM compatibility or want to see whether your device is on the list of eSIM-supported phones, the first step is always confirming that your phone is unlocked.

 

Here’s how to quickly check if your device is unlocked.

 

Why Unlocking Matters

If your phone is locked:

  • You won’t be able to install an eSIM from Roamvy or other providers.
  • You’ll be tied to your home carrier’s expensive roaming plan.
  • You can also smoothly check eSIM compatibility when buying travel data plans.

 

If your phone is unlocked:

  • You’re free to add a Roamvy eSIM in seconds.
  • You can switch between networks around the world with no restrictions.

 

How to Check if Your iPhone is Unlocked  

Method 1: Check in Settings

  1. Go to Settings > General > About.
  2. Scroll down to Carrier Lock.
    • If it says “No SIM restrictions”, your iPhone is unlocked.
    • If it lists a carrier, your phone is locked.

 

Method 2: Try a Different SIM (Optional)

Insert a SIM card from another carrier. If it connects, your phone is unlocked. If it shows an error, it’s locked.

If you’re using an iPhone from the last several years, it’s likely already on the eSIM-supported phones list — but checking the unlock status is still important.

 

How to Check if Your Android is Unlocked

Method 1: Check in Settings

  1. Go to Settings > Connections > Mobile Networks > Network Operators (Samsung)
  2. or Settings > Network & Internet > SIMs (Pixel).
    • If you can see and select multiple carriers, your phone is unlocked.
    • If only your current carrier appears, it may be locked.

 

Method 2: Try a Different SIM (Optional)

Insert a SIM from another provider. If it works, your device is unlocked.

Many modern Android devices are eSIM-supported phones, especially Samsung, Google Pixel, and newer models from Xiaomi, Oppo, Vivo, etc. But again — unlock status must be confirmed first.

 

What to Do if Your Phone is Locked

  • Contact your carrier: Most carriers will unlock your device for free once your contract is paid off.
  • Request early unlock: Some carriers allow unlocking for a fee before the contract ends.
  • Verify before you travel: Unlocking can take a few days, so don’t wait until the last minute.
