In this article, we will show you the best solutions on unlocking a locked SIM Card and the different types of sim card locks for your information.
Overview of Smartphone
Smartphone prices are soaring year after year with every new launch by smartphone manufacturers. Thankfully, global and local network carriers have certain plans through which they can offer flexible payment options in installments, enabling you to buy expensive smartphones at affordable rates.
These contracts make it quite easy for users, but if, for some reason, you want to use your phone with a network carrier other than the original one, you may face difficulties.
All this talk above was about network-locked SIM cards & not about locked SIM cards, which are generally caused by entering the wrong code or PIN on a repeated number of occasions.
In the next section, we’ll dive deep into both these types of locks and the best methods on how to unlock the locked SIM cards.
Part 1: Types of SIM Locks
Before going into details on how to unlock SIM cards, you should dig into the following brief on the types of SIM locks you may have. You might be faced with a Network locked SIM card, or SIM Card locked.
Besides, if you are looking for software to unlock phones to any network, just click to have a try.
1. Locked SIM:
Sometimes, people like to use some additional security features on their phones, such as SIM locks using a PIN code or a password. It is usually aimed at preventing unauthorized use of your SIM card in case of theft. You have to enter the SIM PIN to use your phone.
If you enter your SIM PIN wrongfully three times or more, your SIM card will be locked, and you will need a PIN to unlock the key, shortly referred to as the PUK code. You should contact your network carrier in case you do not already have one.
In addition, if you wonder about how to change the IMEI number on your iPhone, here are the easy solutions you should check out.
2. SIM Card Locked from Network Provider
In most cases, smartphone buying is always a big investment considering the market prices we have today. Once you finalize your choice for a smartphone, next comes the network service provider.
Why it’s necessary? Simply because in most countries, smartphones are sold under contract with network service providers. The big reason for the success of this model is its relatively reduced prices compared to what you’ll get if you buy it outside the contract.
But the downside of this is that you can’t use any other network provider on that particular phone. As it’s protected by a certain Pin code, and you’ll have to enter that code to unlock your sim card to operate your phone.
To use any other network on your phone other than the original one, you must have an unlocked SIM card if you wish to travel or want to switch to other networks for any reason. There is not necessarily a complex operation; it will go smoothly if you follow the guides
Step-by-Step Guideline to Check if Your Phone is Locked or Not:
- 1-First of all, switch off your phone.
- 2-Once the phone is switched off, remove the sim card from it.
- 3-Now insert any other network sim card.
- 4-Now turn on your phone.
If the newly inserted sim works perfectly on your phone, then your phone isn’t locked by the network provider, but if you are asked to enter the PIN code, it is most definitely locked.
There can be two different reasons for this lock.
A. Locked by Network:
If you can’t use any other sim card, just as explained above, then your smartphone is locked by the network. Now some network providers offer the service to unlock your sim card, which we’ll cover later on.
B. Region Lock:
Although it’s not a very common case, some mobile manufacturers do offer separate versions of the same model of their phones in different countries. For example, a mobile model version “A” that is working in the USA might very well not work in Canada. There are many reasons why it is done and why manufacturers do it. We’ll discuss this later on in detail.
Part 2: How to Unlock SIM Card using PIN Unlock Key (PUK)?
When you have a locked SIM card due to the wrong PIN or have forgotten your PIN (not a network-locked card), the process to unlock the SIM card is pretty straightforward.
Follow the below steps on how to Unlock your SIM Card:
- 1. To unlock your SIM card, you first need to know your IMEI number. You can easily get your IMEI number by dialing *#06#, or you can find your IMEI number on the box of your smartphone.
- 2. As a next step, you need to call your network carrier. They will ask you for some information for verification, and upon successful verification, they’ll send your PIN Unlock Key (PUK).
- 3. Once you get a PUK code, turn your phone on. Upon restart, you will be requested to enter a PIN or enter PUK. Enter the PUK code provided by the network carrier and press OK.
- 4. Once you enter PUK, you’ll need to enter a new PIN code.
- 5. Please verify a new code by entering it again. Press OK, and you have successfully unlocked the SIM card.
- 6. Verify your new PIN code by typing it in again when you see the prompt. Press OK once again, and your SIM becomes unlocked.
BONUS TIP: PUK codes are also mentioned on the SIM card jacket/pack. You can save all this hassle of calling your carrier and getting a code if you have it saved when you buy it.

So who would want to buy a phone at full price when you can get it at a lower price?
But there is one downside: you couldn’t use this phone to operate the sim card provided by another network provider. So what to do if you want to get rid of your current sim card and replace it with a new network provider?
