    How SIM Unlock Software Works?

    Once you insert a T-Mobile SIM to AT&T registered phone, you might see the error notification saying SIM Not Supported or SIM Not Valid. This is because the phone is locked to the AT&T carrier. You can’t use any other SIM card without unlocking the phone. The phones are locked through a secret code known by the carrier. To unlock the device, this secret code needs to be identified. Depending on their terms and conditions, you can request your carrier to unlock the device.

    But if you want to unlock it yourself, you need to have special software to break the secret code. This code is derived cryptographically, so no person can’t guess or predict the code manually unless they have the decrypting code. There are people on eBay who do unlock the phone upon providing them with the IMEI. But these methods are not permanent, and they won’t take any responsibility for device failures. In most cases, the carrier locks the phone due to your terms with them as the customer.

    On some occasions, you may feel unlocking the phone is illegal and insecure. But in the real case, unlocking doesn’t harm the mobile phone, SIM card nor threaten your privacy. It is completely a legal process for people who don’t want to pay extra money for the carrier to unlock the device within the contract period.

    Final Words

    We hope you no longer need to wait until the expiration of the contract period to unlock the device. You can unlock the device by using one of the SIM unlock software we mentioned above. Remember, some methods might bring you temporary unlocking, and after a few days, you might need to redo the unlocking steps. So be careful when selecting the software for unlocking. We recommend trying iToolab SIMUnlocker, the iPhone SIM unlock software that you can use to solve many issues related to iOS.
