If your phone is locked to a specific network it is actually the phone itself locked. Not a SIM card.
In fact, GSM carriers can use software on phones so that a particular phone will receive only the selected SIM card from a specific network. If the phone and SIM card do not match, the phone will not work. This is what it means when the phone is “locked.”
Turning on the phone, then, removes this restriction so that the phone can receive SIM cards in other networks (find out how to remove your SIM card). In the event that you plan to sell your phone, this is an important consideration as you will need to unlock it before the buyer can use it. The same thing applies when you buy a locked phone.
There is another important factor to consider: prepaid SIM cards. These SIM payment cards as you travel do not require registration or contract. And they are usually cheap, especially if you buy them from MVNO. This can be a great help if you are traveling internationally and want to avoid the high cost of travel.
