What is the difference between a Mars eSIM Card and a standard SIM card?
Physically, they look identical and fit into the same SIM slot. The difference lies in their function: a standard SIM card is pre-linked to a specific carrier and data plan, whereas the Mars eSIM Card is a physical bridge that enables eSIM capabilities on your device. It arrives blank, allowing you to install and switch between international eSIM plans via an app. This effectively brings eSIM functionality to Android phones that don't natively support it.
Does this card come with a pre-included data plan?
No. The Mars eSIM Card provides the eSIM functionality only and does not include any pre-installed data plans. After receiving the card, you will need to purchase a plan from the Mars eSIM Store or scan an eSIM QR Code provided by another carrier to install it. You will be able to access the internet once the plan is activated.
Do I have to use the Mars eSIM App with the Mars eSIM Physical Card?
Yes. To ensure the best user experience, please use the Mars eSIM App to manage your plans. We strongly recommend avoiding your phone’s built-in eSIM management tools to prevent potential compatibility issues. You can download the Mars eSIM App for free from the Google Play Store to easily manage multiple eSIM profiles.
Can I use it with an iPhone or iPad?
It is not recommended at this time. The core functions of the Mars eSIM—such as downloading and managing eSIM plans—must be performed through our dedicated Android App. Currently, iOS devices do not support this app, making it impossible to install or manage plans on an iPhone or iPad.
My phone has dual SIM slots. Can I use two Mars eSIM Cards at the same time?
Currently, we only support the use of one Mars eSIM Card per device. However, a single card can store between 8 to 10 eSIM profiles. Whether you are traveling for business or leisure, you can enjoy hassle-free internet access by easily switching between your saved plans.
What happens to my original number if my phone only has one SIM slot?
Since the Mars eSIM Card occupies the physical SIM slot, you will need to free it up to use our service. If you wish to keep your original number for calls, we recommend converting your primary number into an eSIM through your current carrier. (Many carriers offer the first conversion for free). Once the slot is empty, you can insert the Mars eSIM Card and enjoy its benefits.
