What is a Dual or Hybrid SIM?
Smartphones come in either dual SIM or single SIM models. Dual SIM models allow you to use two SIM cards in one device. This is handy if you have separate phone numbers for work and home or if you need to use a local number while keeping your original number active when in a foreign country. This convenient feature was first introduced on the Galaxy S8 and S8+.
Dual SIM card trays feature 2 SIM card slots, where a hybrid SIM tray features 1 SIM card slot and a hybrid slot. A hybrid slot can take either a second SIM card or a microSD card for expandable memory, giving you the flexibility to choose between a second SIM card or extra storage.
To check if a particular model has a single, dual or hybrid SIM, visit our support website. Alternatively, if you have the phone you can check by removing the SIM card tray and seeing how many slots it has and how the second slot is labelled, if it says SIM2 it's a dual SIM, if it says SIM2 \ microSD it's a hybrid.
