How to make a hybrid of a sim card and a memory card
SIM-card (English Subscriber Identification Module - subscriber identification module ) - subscriber identification module used in mobile communication. SIM-cards are used in GSM networks. Other modern cellular networks usually also use other identification modules, usually externally similar to SIM and performing similar functions - USIM in UMTS networks, R-UIM in CDMA networks, etc.
A memory card (sometimes incorrect flash drive) is a compact electronic storage device used to store digital information. Modern memory cards are made on the basis of flash memory, although in principle other technologies can be used. Memory cards are widely used in electronic devices, including digital cameras, cell phones, laptops, portable digital audio players
The video instruction will teach how to combine any SIM card and microSD memory card into one device without loss of functionality!
Modern Chinese and Korean smartphones increasingly have a universal dual slot, in which you can insert either two SIM cards or a SIM card and a microSD memory card. However, there is a very simple way to make it so that the two-card slot fits ... three! Namely - two SIM cards plus a memory card.
For this you need to make a kind of hybrid of a microSD memory card and a sim card. This is quite realistic due to the fact that the contact groups of the memory card and the SIM card are located in different places. Therefore, we take a SIM card, carefully separate the contact group from the plastic base, cut off the edges and paste it onto the MicroSD card.
Done! Thus, we received two full-fledged SIM cards and a microSD memory card in a double slot.
