Unlock a Samsung phone with a code.
When you purchase a Samsung cellular phone from a service provider, the phone is locked to the provider's service. The phone cannot be used with a SIM card from another service provider. Instead of purchasing a new cell phone if you switch providers, it is possible to unlock the phone so a new SIM card from any company can be used. The service company can unlock your phone, for a fee, or you can enter an unlock code found online. No more buying expensive phones once you learn the simple technique to unlocking your Samsung phone for free.
