Planning to travel abroad and wondering if you can use a local SIM or a travel eSIM like eSIM Europe from Orange? One of the first steps is to check whether your phone is unlocked. If your device is still restricted to a specific carrier, you may face higher roaming costs or be unable to connect to a local network.
In this article, we’ll show you how to check if your phone is unlocked, explain the difference between locked and unlocked phones, and guide you through the process of unlocking your device. We’ll also highlight the benefits of having an unlocked phone, especially for international travelers.
What Is the difference between locked and unlocked phone?
A locked phone is tied to the mobile network of the provider that sold it. This means you can only use it with that specific carrier unless you unlock it.
In contrast, an unlocked phone can work with any carrier that is compatible with your device, whether you’re inserting a physical SIM or using a digital eSIM. This flexibility is especially useful when traveling or switching carriers to find better deals.
Here are the key differences:
| Locked Phone | Unlocked Phone |
|---|---|
| Tied to a single carrier | Works with any compatible carrier |
| Limited for international use | Ideal for global travel and eSIM usage |
| May require unlock request | Ready to use with any SIM or eSIM |
| Harder to resell | Higher resale value |
How to check if your phone is unlocked?
Wondering how to check if phone is unlocked? There are several ways to find out. Below are the four most common methods:
Method 1 : check your phone settings
On iPhone:
- Go to Settings > General > About
- Scroll down to Carrier Lock
- If you see “No SIM restrictions”, your phone is unlocked.
- If it says “SIM locked”, your phone is still tied to a carrier.
On Android (may vary slightly):
- Go to Settings > Network & Internet > Mobile Network > Advanced
- Tap on Network Operators
- If you see a list of available carriers (not just one), your phone is likely unlocked.
Method 2 : ask your carrier
Your mobile provider can confirm whether your phone is unlocked. To do this:
- Call or message customer support.
- Provide your IMEI number (dial *#06# or check in your settings).
- They will let you know your device’s status and, if needed, guide you through the unlocking process.
Method 3 : IMEI Checker
Online IMEI checker tools can help determine your phone’s lock status. You’ll need to:
- Retrieve your phone’s IMEI (Settings > About Phone or dial *#06#).
- Use a trusted IMEI checker (make sure it’s from a reputable source).
- Enter the IMEI to get instant results.
- This is a quick way to check, especially if you don’t have access to another SIM card.
Method 4 : switch SIM Cards
- Power off your phone.
- Insert a SIM card from a different carrier.
- Turn your phone back on.
- Try making a call or using mobile data.
If the phone works with the new SIM, it’s unlocked.
If you see a message like “SIM not supported”, it’s locked.
How to unlock a locked phone?
If your phone is locked, don’t worry you can usually unlock it. Here’s how:
- Contact your carrier and request an unlock.
- Make sure your phone meets the requirements:
- It may need to be fully paid off.
- It might have to be active on the network for a certain period.
- Provide the IMEI number.
- Wait for confirmation. Some unlocks happen instantly; others take a few days.
Once unlocked, your phone will accept any compatible SIM or eSIM including Orange Travel eSIM Europe.
Why should you unlock your phone?
