You bought a new SIM card from another operator and it doesn't work on your mobile or tablet. Confused, you call the new network provider and learn that your smartphone is locked to the first network and you can't do anything about it. Of course, this is not strictly true. Here are three possible options for unlocking your device.
Unlocking your device via the sim card
As amazing as it sounds, you can contact your operator to unlock your phone or tablet via the SIM card. This is your best option. Since February 2015, cell phone owners have been able to ask the operator from whom they purchased the phone to unlock it. Network providers must also inform customers via a notification on the monthly bill if the device is eligible for unlocking. If you have a contract and it has not yet expired, you will have to pay an early termination fee to obtain the unlock code. Those who purchased the phone directly without a subscription will be able to switch operators 12 months after the date of purchase.
Unlocking and confirming the IMEI number
To break the network / SIM lock, you must confirm the IMEI (International Mobile Equipment Identification Code) number used to identify your phone on any network on your phone or tablet. On Android, the IMEI number can be quickly found by dialing * # 06 # or by opening Settings> About Phone> Status> IMEI Information. With this 15-digit string, you will get a PIN or PUK code that will allow you to use a SIM card from another network operator.
Find a reputable mobile unlocking service
If your network provider does not accept the request to unlock your mobile, you can find specialized smartphone unlocking services shops on
https://www.the-shops.co.uk/ close to your home. You can also find unlocking services online. However, finding such a service can be difficult. It is recommended that you only use this type of service if you have no other options. These sites, which will ask you for the device's IMEI number to create the unlock code, are not always reliable.
Unlocking your phone using the SIM card may not be ideal. You'll need to weigh the pros and cons if you plan to switch operators before your contract expires, as there is a cost to doing so.
