How To Unlock SIM Cards Of Tecno Spark 10 4G Without PUK Codes

This comprehensive guide explores how to unlock SIM cards without the PUK Codes. Whether you’re a techie or a tech noob, you’ll be sure to find easy solutions in this article. From directly contacting your mobile carrier to utilizing alternative unlocking techniques, you will see clear and concise instructions that empower you to navigate this technical hurdle.
Part 1: Official Ways To Unlock SIM Cards With a Lost PUK Code
Locking your SIM card with a forgotten PIN can be a frustrating experience, especially when your trusty PUK code seems to have vanished. While unauthorized methods exist to unlock your SIM card, venturing down that path can lead to complications and potential security risks. This guide prioritizes safe and official methods, ensuring a smooth and secure unlocking process with the help of your mobile carrier.
Firstly, remember that the PUK code typically arrives alongside your SIM card in its original packaging. Keeping this information safe alongside your other crucial documents is always helpful. However, if memory betrays you and the packaging is nowhere to be found, this part will show you how to unlock SIM cards without PUK codes with the help of your carrier.
Method 1: Contacting Your Carrier’s Customer Service
The most straightforward approach is contacting your mobile carrier’s customer service department directly. Their representatives are trained to assist in such situations and can verify your identity before providing the PUK code. Be prepared to answer security questions and provide relevant account details to ensure a smooth process.
Here’s what you’ll need:
- Ready your information. Prepare your account number, phone number, and any other relevant details your carrier might require for verification.
- Find the best contact option for you. Most carriers offer multiple options like phone calls, online chat, or visiting a physical store. Opt for the method that best suits your preference and availability.
- Prepare a written report of what happened. Clearly state that you’ve locked your SIM card by entering an incorrect PIN and have lost your PUK code.
- **Verify your identity.**Answer the security questions or provide the requested account details to confirm that you’re the authorized user.
- Receive your PUK code/new SIM card. Once verified, the representative will provide you with your PUK code. Be sure to write it down in a secure location for future reference. They might offer you a replaced SIM card if no PUK codes exist.
- **Unlock your SIM card.**Enter the PUK code on your phone following the specific instructions provided by your carrier. This typically involves entering the PUK code followed by a new PIN.
Method 2: Retrieving the PUK Code Through Your Carrier’s Website
Many mobile carriers offer self-service options on their websites, allowing you to manage your account and access information independently. If your carrier provides this functionality, you can retrieve your PUK code online without contacting customer service. This way, you’ll learn how to unlock SIM cards without PUK numbers.
Here’s how it might work:
- Step 1: Navigate to the secure section of your account using your login credentials. For example, this is what you can see from the JIO website:
- Step 2: Different carriers have varying website layouts, so refer to their specific instructions or search features to find the dedicated section for retrieving PUK codes.
- Step 3: Similar to contacting customer service, you might need to verify your account ownership through security questions or other verification methods.
- Step 4: Once verified, your PUK code should be displayed on the screen or sent to your registered email address.
Remember, these steps are general guidelines, and specific procedures may vary depending on your carrier. Consult your carrier’s website or contact customer service for the most accurate and up-to-date information.
By following these official routes, you can safely and securely bypass the PUK code hurdle and regain access to your vital mobile services. Stay tuned for Part 2, where you’ll explore alternative unlocking methods for those who prefer a different approach.

As an Android device user, you may have come across a situation where you need to change your device IMEI number. The International Mobile Equipment Identity (IMEI) is a unique 15-digit number assigned to every mobile device, such as smartphones and tablets. This number serves as an identifier, helping to distinguish your device from millions of others. One of the main reasons people want to change their Android IMEI number is to unblock a device that has been blacklisted by their network provider. Other reasons include accessing certain network features and services or maintaining anonymity.
Changing your Android IMEI without root access may seem like a daunting task, but this comprehensive guide will walk you through the process step-by-step. Before proceeding, please note that altering your device’s IMEI number can be illegal in some countries, and may void your warranty. Proceed with caution and at your own risk. Get to know how to change IMEI number now!
Part 1: What is IMEI and Why People Change The IMEI Number
The International Mobile Equipment Identity (IMEI) is a unique identifier for every mobile device. It allows network providers and manufacturers to track and block devices if they are reported as lost or stolen. Changing your device’s IMEI can help to unblock a blacklisted device, access certain network features and services, or maintain anonymity. However, be aware that altering your IMEI number is illegal in some countries and may void your warranty.
There are several uses of the IMEI number
- As the use of mobile devices increases, the statistics of stolen and lost devices have been increasing as well. Users can block stolen or lost devices for further usage if they know their IMEI number. All users need to call their network carrier and report that the Tecno Spark 10 4G device is stolen or lost. The carrier can block the specific device from running on their network and notify other carriers.
- The 15-digit IMEI number indicates the origin and model of the Tecno Spark 10 4G device. The first eight digits indicate the Tecno Spark 10 4G device’s origin and its model while the last six digits identify the Tecno Spark 10 4G device’s manufacturer.
- If you subscribe to a mobile tracking service, you can use the IMEI number to track the Tecno Spark 10 4G device—even if it uses a different SIM card.
Pros and Cons of Changing Android IMEI
Like many other things out there, changing Android IMEI has both advantages and disadvantages. Here are some of them:
Advantages
- Make your Android untraceable. By constantly changing your IMEI, you will throw off the tracks of people using it to stalk you!
- Fix any invalid IMEI-related issues such as lost or invalid IMEI numbers. Once you change your IMEI, your Android device with the same benefits and features.
- Obtaining a completely new device ID.
- Changing the IMEI number to one that indicates it is a newer model, you will be able to enjoy new OS updates by resetting, repairing, and updating your Android device.
- Have you ever yearned for that cheap BlackBerry plan your network carrier keeps on promoting? The 15-digit IMEI indicates the origin and model of your device. Therefore, by changing your Android’s IMEI number to that of a BlackBerry’s, you will be able to subscribe to a cheaper mobile plan.
Disadvantages
- Before we begin, we need to make it clear that the process of changing IMEI without root can be illegal in some countries. We advise you to check the laws and regulations in your country before attempting to change your device’s IMEI number. As far as we know, it is legal in Africa and Asia, and illegal in Europe.
- The IMEI number is hardcoded into your device. Therefore, changing your device’s IMEI number may void your device warranty and cause other issues such as network problems and software instability.
- Legally, you have forfeited your ownership of your mobile device. When you purchase your device, the seller will jot down the original IMEI number on your receipt. So if you changed your IMEI and lost it, you may not be able to claim it. This is because authorities cannot see if it is truly yours. After all, the IMEI numbers no longer correlate with each other.
Part 2: How to Find the IMEI on an Android? (5 Ways)
It is essential to know your Android device’s IMEI for various reasons, such as registering the Tecno Spark 10 4G device, reporting it as stolen or lost, checking warranty status, or verifying its authenticity. In this part, we will walk you through the various methods on how to find the IMEI on your Android device.

No, swapping or changing the SIM card does not alter the IMEI (International Mobile Equipment Identity). The IMEI persists unchanged throughout the Tecno Spark 10 4G device’s lifetime, functioning as a distinctive identifier solely for that particular device.
The IMEI is a 15-digit code assigned to each mobile device. It’s separate from the SIM card, which stores information related to the subscriber and the carrier network. The SIM card contains data specific to the subscriber. This includes contacts, text messages, and network-related information. But it does not alter or affect the IMEI of the Tecno Spark 10 4G device.
The IMEI remains the same even if you change SIM cards or switch between different carriers. It’s essentially a static identifier tied to the Tecno Spark 10 4G device’s hardware. It is used by mobile networks and authorities to identify and track devices on the network.
Part 4: Does IMEI Change After Factory Reset?
No, performing a factory reset on your mobile device does not change its IMEI (International Mobile Equipment Identity). The IMEI is a unique identifier assigned to the hardware of the Tecno Spark 10 4G device. It remains constant throughout the life of the Tecno Spark 10 4G device, irrespective of any software changes or resets.
A factory reset wipes the data and settings on your device, returning it to its original factory state. This process erases user-installed apps, personal data, and settings. But it doesn’t affect the Tecno Spark 10 4G device’s hardware identification, including the IMEI.
The IMEI is embedded into the hardware of the Tecno Spark 10 4G device. It is typically printed on the Tecno Spark 10 4G device’s packaging or can be found by dialing *#06# on the phone’s keypad. It’s a crucial identifier for mobile networks, and authorities use it to uniquely identify and track devices across networks. It remains unchanged even after a factory reset.
