What’s a SIM card?
A SIM card is a small, flat, plastic card that transmits signals and information from telecom carriers (phone companies, like UNREAL Mobile to communication devices (phones, tablets, and mobile hotspots).
SIM stands for Subscriber Identity Module and SIM cards typically, but not exclusively, contains the following information:
- A phone number
- Contact lists
- Network authorization data
- Calling history
- Text messages
When you buy a SIM card from UNREAL Mobile, and insert that SIM card into a compatible phone, UNREAL Mobile can supply your phone with an internet connection and cellular (calling and texting) services. SIM cards can only transmit signals to phones that are open to read and receive those signals.
Locked phones (phones that are set to work only with certain carriers, like T-Mobile or Verizon) cannot read the information on our SIM cards. So it's important the phone you're using is unlocked.
Note: With our newer, Premium Service, if you have purchased a physical SIM your phone may be compatible with the AT&T. If you do not have a sim or plan please visit https://unrealmobile.com/plans to see our available talk, text and data plans with eSIM.
Our talk, text, and data SIM cards work with GSM unlocked, Android, and iOS smartphone devices.
