Smartphones with a hybrid SIM card slot

2 SIM (SIM + SIM / memory card)

— phones with two slots for SIM cards (see "2 SIM cards"), in which one of the slots has a combined purpose and can be used either for the second SIM card or for a microSD memory card. This somewhat simplifies and reduces the cost of the design, however, it is impossible to install two SIM cards and a memory card into such a device at the same time — something has to be sacrificed. So if it is fundamentally important for you to use 2 SIM cards and a memory card, you should pay attention to devices from the “2 SIM slots + memory card” category (see the relevant paragraph).
