<— Return to: Above DataSIM


Please note that the DataSIM is an eSIM, which means that you can only use the DataSIM on devices that support eSIMs. All the phones we sell support eSIMs and multiple SIMs can be added to a device, ready to be used on demand.

Note that a maximum of two SIMs can be active at the same time.

Since most devices have only one physical SIM slot, at least one of the secondary SIMs needs to be an eSIM to be able to use it simultaneously.


SIM card vs. eSIM vs. DataSIM:

  • SIM Card
    A small chip that holds and sends authentication details (IMSI) to the mobile cell network. When a phone number is tied to the SIM card, it allows to make and receive phone calls, SMS (text messages) and MMS (media messages). Additionally SIM cards can also give access to the internet via mobile data / broadband. SIM stands for Subscriber Identity Module Card.


  • eSIM
    Nowadays SIM cards don't have to by physical cards anymore - with newer phones it is possible to directly download electronic SIM cards (=eSIM) into the phone, usually by using QR codes.
    An eSIM is a form of SIM card that directly is embedded digitally into a device. Note that in terms of privacy concerns, eSIMs are no different to physical SIM cards, since both always connect to nearby cell towers and the data stream can be identified when there is a telephone number directly tied to that SIM card.


  • DataSIM
    We have introduced this term to make it clear how the SIM cards we offer differ from normal SIM cards. The Above DataSIM does NOT have a phone number tied to it and instead just uses the nearby cell towers to provide internet to the phone, making it possible to use any internet based service, including virtual phone numbers, like the ones from JMP.chat
