How to Put Contacts on Samsung S7

Samsung decided to listen to the opinion of its fans and returned to the new flagship devices Galaxy S7 and Galaxy S7 Edge support for memory cards. However, she did this using a hybrid slot, as it has become fashionable recently. This means that the user must choose to use 2 SIM cards or one SIM card and a microSD card in the smartphone. Fortunately, craftsmen were found who discovered that the contacts of the second SIM and the contacts of the memory card are in different places and managed to combine business with pleasure and organize the simultaneous operation of two SIM and microSD cards. And if you decide to become the owner of a new device (or have already become), despite all its minor disadvantages, then this article is for you. We publish a translation of the instructions with detailed comments on installing two SIM cards and a memory card in the Galaxy S7 and Galaxy S7 Edge.


Denial of responsibility:
all the manipulations listed below you do only at your own peril and risk. Neither the author nor anyone or anyone else is responsible for your actions and for any damage caused. There is a high probability of damage to the microchip of the SIM card, to a lesser extent. the microSD memory card. Also, when the smartphone heats up, there is a danger of peeling off this design and in which case problems may arise when removing the tray. It is possible that to get it you have to contact the service center. In this case, the device is removed from the warranty.

So, if you have realized all of the above risks, then to continue you will need the following devices:

  • SIM card in Nano format (because it’s easier to cut and “disassemble”)
  • MicroSD memory card
  • Lighter
  • Scissors, blade or any other sharp object
  • Thin double-sided tape (preferred) or super glue
  • A bit of free time, patience, a head on shoulders and straight arms

To install two SIM cards and a memory card at the same time in Samsung Galaxy S7 or Galaxy S7 Edge you need:

  • Determine the correct position of the SIM card
    First you need to determine the correct position of the SIM card in the tray. Cards of different operators can have different configuration of contacts. The author of the original instruction conducted operations on SIM-cards of U Mobile and Maxis operators (Malaysia). Usually, all SIM cards have a special key on one side (cut corner).

  • Disconnect the SIM card chip from the base
    Any SIM card consists of a plastic base and a microchip glued to it with a contact pad. Gently heat the SIM card from the opposite side (where there is plastic). This may take from 30 seconds to 1 minute. Then carefully separate the chip with the contact pad from the base. As an auxiliary tool, it is recommended to use a sharp object (scissors, knife, blade, etc.). After that, the chip needs to be cleaned of glue or plastic residues.
    If everything went smoothly and you did not have to change the SIM card, then you can consider half the way passed.
  • Trim microchip SIM card
    Now you need to carefully trim the contact pad of the SIM card to place on the memory card. Usually it is required to shorten it by 1-2 mm on each side (as in the photo).
  • Fix SIM card to microSD
    This can be done using double-sided tape (in which case the memory card can be easily (less) “released”) or with super-glue (this option is less preferable, since if you damage the SIM card chip, separate it from the memory card it will be quite difficult or even impossible). For the correct placement, the first step was provided. In addition, make sure that the angle of the microchip of the SIM card is aligned as in the image (circled in red).
  • Place the finished structure in the tray
    Now it remains to put the genetically modified microSD card into the tray, and the tray itself into the smartphone.

Finally, you need to check the correctness of all actions. If everything is done correctly, then the Galaxy S7 will “see” two SIM cards and a microSD memory card. It will look something like this:

It is also worth noting that the method described above is suitable for all smartphones with the same hybrid SIM card tray. In particular, owners of Meizu Pro 5 have similar experience.
