• This product comes with a preloaded 5G unlimited data plan. After receiving the card, simply insert it into your phone’s physical SIM card slot to activate the service.

• Please make sure your phone is not locked to a specific carrier and has no SIM Lock. If your phone is carrier-locked, such as some contract phones purchased overseas, this product cannot be supported or used, whether with the preloaded plan or for future use through the App.

• The preloaded plan must be activated within 90 days after placing the order. Activation means that you have arrived at the destination covered by the plan and your phone has successfully connected to the local mobile network for data transmission. If the plan is not connected to the network at the destination within 90 days, the preloaded plan will automatically expire.

• The preloaded plan supports all unlocked phones and tablets with a physical SIM card slot, including iPhone and iPad.

• After the preloaded plan ends, if you wish to reuse the card to install and manage multiple global eSIM plans, you must use a compatible Android phone with the Mars eSIM App.

• At this stage, all mobile phone models purchased in Mainland China, as well as devices running Huawei HarmonyOS, are not supported.

• Please make sure your phone is running Android 9.0 or above before placing an order. Older system versions are not supported by this product.

• Before purchasing, please search for and try downloading the Mars eSIM App from the Google Play Store. If your device cannot find the App or shows “Your device is not compatible,” it means your device does not meet the hardware requirements. Please do not purchase.

• eSIM plans purchased from other platforms or providers may not be installable on the Mars eSIM Physical Card due to their own settings or restrictions. Before purchasing a third-party eSIM plan, please confirm with the platform or provider whether the plan supports installation through a third-party App or on the Mars eSIM Physical Card. 

Please DO NOT “Enable” or “Disable” the Mars eSIM physical card through your phone’s built-in SIM card manager. Doing so may prevent both your phone and the App from detecting or reading the card.

• This product must be inserted into a physical SIM card slot. If your phone only has one physical SIM slot and you wish to keep using your original phone number, please contact your carrier to convert your original physical SIM card to an eSIM first, so the physical SIM slot can be used for this product.

• If your phone supports dual SIM, please note that two Mars eSIM physical cards cannot be installed in the same phone at the same time. Each device can only detect and operate one Mars eSIM physical card at a time.

• No hardware warranty or reissue is provided. We recommend testing app connectivity during the inspection period to ensure long-term compatibility.
