Let’s get started!
Part 1: What Does “Network Locked SIM Card Inserted” Mean?
The Network locked SIM card inserted message indicates that your phone is currently locked to a specific network provider, and it refuses to accept SIM cards from other carriers.
Hence, your phone is tethered to one network limiting you to switch to other providers and this can be a real hassle, especially if you want to travel internationally.
Note: Unlike certain other brands, Samsung refrains from imposing any restrictions on its devices. To resolve the Network-locked SIM card inserted Samsung error, reach out to the original service provider or retailer for an unlock code
Why Does This Message Appear?
Let’s check out the possibilities as to why the error invalid SIM card network locked appears.
The most common reason is that your phone is locked to a particular carrier. This usually happens when you purchase a subsidized phone or sign a contract. To unlock it, you’ll need to meet certain criteria or contact your carrier.
If you bought a used phone, it might still be locked to the previous owner’s network.
Incorrect SIM Card
Sometimes, the issue arises from using an incompatible SIM card or one from a different carrier.
Occasionally, software glitches or updates can trigger this error which may create confusion.
Part 2: How to Fix the “Network Locked SIM Card Inserted” Error?
Remember, unlocking your phone should be done legally and in compliance with your carrier’s policies. Always back up your data before you have access to your phone so it can be recoverable after attempting any unlocking method.
Now it’s time to look into the possible fixes.
Solution1. Contact the Network Carrier
If you’ve recently changed your network provider and encountered this error, your previous service provider can often provide you a code of 8-16 Digits but here’s what you need to know:
Ensure you’ve used the default carrier for a minimum of 3 to 6 months, depending on their policy. Additionally, make sure you’ve paid off the full price of your smartphone or be prepared to pay a termination fee.
Let’s take an example of network-locked SIM cards inserted in Samsung for the unlocking process.
- Power off your Samsung smartphone and insert the new SIM card.
- Restart your device, and it will prompt you for an unlock code.
- Enter the code provided by your previous carrier. Be cautious, as entering the wrong code can lock you out of your device.
