1. Understanding SIM Lock

1.1 What is a SIM Lock?

A SIM lock is a restriction imposed by mobile carriers that prevents a phone from being used with SIM cards from other carriers. This lock is often implemented to ensure that the phone is used with the carrier that subsidized or sold it, typically as part of a contract or installment plan.

Key Points:

  • Carrier-Specific Restriction: The phone is restricted to work only with the carrier’s SIM card.
  • Contractual Obligation: Often tied to the terms of the purchase or contract.
  • International Usage: Limits the phone’s use when traveling abroad unless unlocked.

1.2 Why Remove SIM Lock?

Removing a SIM lock can be advantageous for several reasons:

  • Carrier Freedom: Allows you to switch carriers without purchasing a new phone.
  • International Travel: Enables the use of local SIM cards in different countries to avoid high roaming charges.
  • Resale Value: An unlocked phone can have a higher resale value as it is not restricted to a single carrier.

2. Preparing for SIM Lock Removal

Before attempting to remove a SIM lock, you need to verify if your Nokia C20 is indeed locked.

Steps to Verify:

  1. Insert a Different SIM Card: Insert a SIM card from a different carrier.

2.2 Gather Necessary Information

To proceed with removing the SIM lock, gather the following information:

  • IMEI Number: A unique identifier for your device, essential for generating the unlock code.
