1. Dispelling Myths about Different Types of Unlocking
1.1 Carrier Unlocking
Carrier unlocking occurs when the restrictions imposed on your Nokia C20 by the network operator are removed so that you can use the phone with a different carrier. This comes handy if you are traveling internationally and wish to use a local SIM card or would like to switch service providers and retain your existing phone.
1.2 Screen Lock Unlocking
If you set a screen password, PIN, or pattern and forget it, you must first unlock the screen to gain access to the Nokia C20. Various procedures are involved here, including unlocking through Google Find My Device, hard resetting, or recovery mode.

An unlocked bootloader allows modification of the phone operating system, custom ROM installation, and root access. This is a rather advanced procedure, and it is normally done by techies who want to extend their customizations beyond manufacturer restrictions.

Carrier unlocking offers some benefits:
Flexibility: Use your Nokia C20 with any carrier worldwide and save you from owning multiple devices or paying hefty international roaming fees.

Switching Providers: Do not allow yourself to be restricted to a single carrier because of its plans, services, or coverage areas.
2.2 How You Can Find Out if Your Nokia C20 is Locked
Before you put your attempt to unlock your Nokia C20 into action, the first thing you’d want to re-confirm is that it is actually locked.

If the phone prompts you to enter an unlocking code or displays a message like “SIM Network Unlock Pin,” then it means the phone is locked by original carrier.
Check with Carrier:
Your carrier might also be able to confirm for you if your Nokia C20 is locked to their network.
2.3 Methods to Carrier Unlock Your Nokia C20
2.3.1 Using an Unlock Code
The unlocking of your Nokia C20 is mostly accomplished through codes supplied by the carrier:
Contact Your Carrier:
Ask for an unlock code. You may have to meet some criteria, like paying for the device in full or being a customer for a certain amount of time.
Receive the Unlock Code:
If you meet the requirements, the carrier will give you an unlock code either via e-mail or as an SMS on your phone.
Insert Another Carrier’s SIM Card:
Make sure your phone is switched off and then go ahead to slot-in a SIM card from the new carrier.
Entering an Unlock Code:
Enter the code when asked, given to you by your carrier. Upon correct entry, your Nokia C20 will then be unlocked and ready for use with the new carrier.
2.3.2 Using Third-Party Services
You can resort to third-party services if your carrier is not capable or willing to provide you with an unlock code. But beware of such: the unlocking process may pose some risks;
Find a Reputable Service:
Look for online services that have garnered positive reviews and have pre-established credibility in the field of providing unlock codes for Nokia devices.

Give the IMEI number of your phone and then proceed to acquire the unlock code. Normally, the IMEI is displayed when you dial *#06#.
Follow the Service’s Instructions:
After you get the code, carry out the directions given to you to free your phone.
