What is an unlocked phone?

What is GSM technology?

GSM (Global System for Mobile Communications) is a type of wireless technology that uses a SIM card to store your account information, such as your phone number, plan details, and contacts. When you insert the SIM card into a compatible phone, that phone can make calls, send texts, and use mobile data. If a phone is not GSM-compatible, it won’t be able to read or use the SIM card.

Locked vs. unlocked phones

Some phones are sold locked, meaning they only work with one specific carrier’s SIM card. For example, a phone locked to T-Mobile cannot be used with a RedPocket SIM until it is unlocked.

An unlocked phone can be used with SIM cards from different carriers, including RedPocket. Phones purchased directly from the manufacturer (like buying an iPhone from Apple at full price) are usually unlocked.

You can also find unlocked phones from retailers such as Amazon, Best Buy, or other electronics stores. When shopping, check the product description and make sure it clearly says “GSM Unlocked” to ensure it will work with your SIM card.
