A locked phone restricts you to one carrier, while an unlocked one accepts any compatible SIM.

An unlocked Samsung phone offers flexibility, while a locked one limits you to a single carrier. Checking the unlock status saves time and ensures compatibility.
With an unlocked Samsung phone, you get more flexibility:
The status of whether your Samsung phone is unlocked can also be checked without another SIM card. All these ways below are simple, without requiring any extra tools or technical skills. Let’s see in detail how they work.
Most Samsung phones show carrier or SIM lock info in settings > usually under About Phone or Status > the exact location may change by model > checking here is fast and does not need another SIM >
Step 1: Open Settings > Connections > Mobile Networks.

Choose Mobile Networks
Step 2: Tap “Network Operators” or “Carrier.” If multiple carriers appear after selecting “Search Now,” your phone is likely unlocked.
Step 3: Check for “Device Unlock” or “Network Unlock.” If absent, the phone is likely unlocked; if present, it’s likely locked.
Every phone has its own 15-digit IMEI number that tells what it is. You can use this number to see if your phone is locked, especially if the settings don’t show it.
Step 1. Dial #06# on your phone and you’ll see the IMEI on the screen.

Dial the Code to Get IMEI
Step 2. You can also go to Settings > About Phone > Status > IMEI to find it. If that doesn’t work, check the box or under the battery.
Step 3. Then open a browser and go to a trusted IMEI checker website. Type in your IMEI and hit Check.
The site will show if your Samsung is locked or unlocked. Some sites might charge a small fee for more details.
The most straightforward way to test if your Samsung phone is unlocked is with a SIM from the other carrier. Insert it, and see if it works. If calls and mobile data go through, the phone is unlocked. If a “SIM not supported” message appears, it’s locked. Easy and anyone can try it.
When another SIM isn’t available, reaching out to your mobile carrier works well. They can confirm if your Samsung phone is unlocked.
Step 1. Check the website or phone number of your provider.
Step 2. To help them identify your phone, keep its information close, particularly the IMEI.
Step 3. Contact them via phone, chat, or email to inquire whether the phone is unlocked or locked.
If the phone is locked, ask about the process to unlock it. Some carriers may require your account verification, payment of dues, or that the phone meet certain criteria.
