⚠️ Important Notice: Currently, devices running Xiaomi HyperOS or Huawei HarmonyOS are not supported.

• Please ensure your phone is running Android 9.0 or higher; older versions do not support this product.

• Before purchasing, search for "Mars eSIM" on the Google Play Store; if you cannot find it or it says "Your device is not compatible," please do not purchase. 

• Confirm your phone is not SIM-locked; devices locked to specific carriers (such as contract phones) will not work.

• This product is a physical eSIM card only and does not include any data or internet plans; plans must be purchased via the app after receiving the card.

• Please DO NOT "Enable" or "Disable" the Mars eSIM Card via your phone's built-in SIM manager. Doing so will prevent the App and your phone from detecting the card. 

• This card requires a physical SIM slot; if you have a single-slot phone and want to keep your original number, please convert your current SIM to an eSIM first to free up the tray.

• If your phone has dual SIM slots, please note that it cannot support two Mars eSIM cards at the same time; only one card can be used per device.
