Why are some devices Locked?

If you buy your phone from Amazon or other top sites/resellers, you’ll be notified if the device is locked or unlocked. Some devices are locked because the owner is yet to complete the payment for owning the device. Most times, when you complete the price for a branded device, the company unlocks the device to allow you to use other networks. However, if your device is yet to be unlocked even after completing its payment, then you should contact your carrier provider to unlock the device.

If you’re using an Android device, the method(s) to check for this differs from that of an iPhone. However, we will discuss how to check if your iPhone and Android devices are unlocked. Let’s do this together! Ready?

Method One: Using Mobile Carrier Logo

You can determine if a mobile phone is a carrier locked by checking the carrier logo on the back of the device. Many mobile carriers put their logo on the back of the mobile phone to identify it as part of their network. If the logo is present, it is likely that the device is carrier locked and can only be used with that specific carrier.

It’s essential to remember that not all carriers put their logos on the back of the mobile phone and that some carriers may have logos that are not easily recognizable. In such cases, it is always best to check with the carrier or the manufacturer and boot screen to confirm the carrier lock status of the device. Additionally, it’s possible for a device to be carrier unlocked even if it has a carrier logo on the back. Hence, verifying the lock status using other methods is always good.

Method Two: Only for Android devices with dual SIM slots

Most Android devices released in recent years feature dual SIM slots; typically, these devices with dual SIM are unlocked; however, to rest assured of this fact, below is how to confirm if your Android device is carrier-locked or carried unlocked.

Steps

• Power off the Android device and stick out the SIM card tray.

• Enter two different SIM cards from other carriers.

• Reboot the Android device.

• Check if the different carrier names of the networks are shown on top of your screen.

• Now dial any mobile number and see if it will go through.

If you can make calls successfully, your device is unlocked and can accept any network carrier. However, if you’re unable to make calls or send SMS, it may imply that your device is locked, or you can call your carrier and see if the issue is from their end.

Method Three: Check Other Network Options

This method will prove if your device is locked or unlocked. Kindly follow the steps carefully. 

Steps:

• Go to your mobile device settings.

• Click on the “Networks” or “Connections” tab.

• Select “Mobile Networks” or “Cellular Networks.”

• Then click on “Network Operators.”

When you click on “Network Operators,” wait for your device to run a scan and fetch the carrier networks. If your device was able to detect multiple carriers, then the device is most apparently unlocked. Nevertheless, on the other hand, if you cannot run this action, then the device is locked.

Method Four: iPhones

This method will work on all iPhones irrespective of the model and iOS version. It is similar to the 2nd method discussed above. Follow the steps below to check if your iPhone device is carrier unlocked.

Steps:

• Go to your iPhone device setting.

• Navigate to the “Cellular” option and click on it.

• Activate the “Cellular Data” option by toggling the switch.

• If you can see “Cellular Data Options,” your iPhone is unlocked.

If you didn’t see “Cellular Data Options,” your device is locked. You need to contact your carrier for guidelines on how to unlock it.

Method Five: Using Model Numbers

Finding out if a mobile phone is carrier locked or unlocked can be determined by its model number. In Samsung Galaxy devices, the model number can often indicate the carrier lock status. If the model number ends with “U,” it is typically carrier-locked. It is restricted to a carrier network and can only be used with that carrier’s services. However, if the model number ends with “U1”, it is carrier unlocked. It can be used with any carrier network and switched between mobile operators. It is important to note that these rules may not apply to all Samsung Galaxy devices. The best way to verify the carrier lock status is to check directly with the carrier or the manufacturer.

Wrap Up

Ensure the best mobile experience by determining whether your phone is carrier locked or unlocked. A carrier-locked phone only operates with its original carrier, whereas an unlocked phone works with any carrier compatible with its specifications.

An unlocked phone can benefit a frequent traveler or someone who spends time in remote locations. It allows you to switch carriers to find the best coverage. Thus, checking and confirming your phone’s carrier status is always wise before making plans. By following these methods and steps, check if your device is locked to a particular carrier or unlocked for use on any network. We know some questions will go through your mind now, and we will clear them up.
