How to unlock a Samsung Galaxy S9 Plus phone locked by an operator?
Before you start unlocking Android phones, let’s briefly explain what network / SIM card unlocking is.
This is simply a process of entering a specially generated code through the keyboard of your phone to remove the restriction imposed by the operator involved in the distribution of the device. This will allow you to insert compatible SIM-cards of any other operators and use their services.
Unlocking with the purpose of using other SIM-cards does not give you full access to the phone. Unlocking the bootloader or rooting. This is a completely different matter. Both of these types of unlocking are legal, but operator assistance is often required to unlock a SIM.

Starting in February 2015, mobile phone owners in America may ask their cellular networks to unlock their devices to switch to another service provider. This puts the United States on a par with the European Union (and repeals the unpopular law passed in 2013). In addition to this, operators are obliged to inform their customers about the possibility of unlocking the device by means of a note on a monthly account.
To get started, find out if your phone can be unlocked. If a smartphone is purchased under a contract, it contains the conditions for unlocking. If the initial two years have not yet passed, you will have to pay a fine for early termination of the contract. After that, you will receive an unlock code and you can safely use another SIM-card.
People who buy their phones directly need to wait 12 full months from the time of purchase and make sure all bills are paid. Then the network will provide you with an unlock code.

It is installed at the factory by the manufacturer, serves to accurately and completely identify the phone on the network. IMEI is stored in a special part of the phone’s memory and actually plays the role of the device’s serial number. (international identifier of mobile equipment. a unique code used to identify your phone on any network) of your phone or tablet.
In Android, IMEI number can be quickly found by dialing # 06 # or opening Settings About phone Status Information about IMEI. After transmitting this 15-digit number, the operator must provide you with a PIN code that allows you to use the SIM card of another network.
(This process may vary depending on the cellular network. For example, a new operator may require you to enter a special code to work with its network.)
This is especially useful if you travel to other countries, and your device does not support working with two SIM cards at the same time.
Although operators in America are not allowed to charge for this service, in the UK and Europe sometimes a small administrative fee is required to unlock the phone.
