Smartphone prices seem to shoot up year after year, and thankfully, you can pay for these devices using several payment options, one of which is by a monthly contract when buying from network carriers. These contracts ease the purchase of these expensive toys, but if you for some reason need to use your phone with a different carrier from the one you are contracted to, issues will arise.
Do not confuse this for a sim card locked, which is caused by entering the wrong sim pin repeatedly. The next section will spell out the difference between these two sim card locks, and the subsequent parts will show you the best methods of how unlock a locked SIM card.
Part 1: Which Situation Are You In?
Check the following situations to decide which methods should you use to unlock your SIM card. You may need to know how to unlock a locked SIM card or how to unlock a network-locked SIM card. Go through all the cases first before you seek the solutions.
A. SIM Card Locked:
Some people like to use the sim card security feature known as a SIM PIN. You must enter this pin to use your phone, as it prevents unauthorized use of your sim card. If you enter the wrong sim pin three times, your sim card will be locked, and to unlock your sim, you need a pin to unlock the key (PUK). You can get this from your carrier.
B. Network Locked SIM Card:
Your contract with your network carrier means that the smartphone will only work with their sim card, at least during the period of your contract. With this, your phone is locked to their network, and no other sim card should work on your phone.
To use another network on your phone, when you travel or simply wish to switch carriers for whatever reason, you will need to unlock the sim card. This is not necessarily a complex operation and should go smoothly if you follow the guides contained in this short article.
Is Your Phone Already Unlocked:
You already know now that to unlock your sim card, you will need a PUK. If you receive a PUK from your carrier, do take caution while entering this key. If you have a phone that you are not sure if it is network unlocked or not, then the fast way to check is by trying a different SIM card in it.
Part 2: How to Unlock A Locked SIM Card
1. How to Unlock SIM Card Manually?
You can easily unlock sim cards manually, if they are not network unlocked, by following the straightforward steps listed below:
Call your wireless carrier’s customer service number. Make sure you have your account’s password handy because they will need you to confirm this before giving you a PUK.
Turn on your phone. On booting, you will be prompted to ‘SIM locked’ or to ‘Enter PUK.’ Follow the prompt and input the PUK code sent by your carrier. Press OK.
Enter a new PIN code (usually four to eight digits) and press OK.
Verify your new PIN code by typing it in again when you see the prompt. Press OK once again, and your SIM becomes unlocked.

Part 3: Get Help from Your Carrier to Unlock Network-Locked SIM Card

You can reach out to your carrier to see if you have met these criteria. If you have, then they will terminate the contract, but note that most carriers charge a certain termination fee, if you have not met the criteria. The most common requirements include the following:
- You must pay for your smartphone fully.
- The device must be up to 3 to 6 months old (depending on the specific carrier).
Follow the steps below:
- Power off your phone.
