Unless you purchased a Samsung cellphone that was specifically described as unlocked, your phone is probably locked, which means it is tied to a specific carrier's cellular service. To use that phone with another carrier, you need to unlock it. You can ask your current service provider to unlock the phone for you. Assuming you don't have a contract or have paid an early termination fee and have paid for the phone itself, your carrier may unlock it in-store or unlock it remotely. If your carrier won't unlock the phone for some reason, you can try to unlock it yourself using one of the free unlocking services available on the internet.

Plenty of people are interested in unlocking their cellphones. If it works, unlocking your phone gives you more freedom in how and where you use it. You may be able to make cheaper calls, install new software, and do more with your phone. After you unlock your phone, though, it may not work with all carriers. Technologies differ among cell service providers, and your phone's technology must be compatible with the provider you plan to use.
Even when the phone works with a different carrier, some of the features may not work as they did previously.
Carrier Compatibility
The two network standards in the U.S. are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA). There are a few GSM/CMDA hybrid phones available, and it looks like most carriers will switch over to GSM. GSM phones have SIM card slots, and Long Term Evolution (LTE) is a GSM standard. Any phone or tablet with LTE must have a SIM card slot.
The moral of this story is that compatibility matters. Contact any cellular provider you are considering before you unlock your phone to make sure that your phone will be compatible with the company's service after you unlock it.
