Many iPhones, Google Pixel phones, and Samsung Galaxy phones take a physical SIM card, but support varies by model and region, and some newer models are eSIM-only. Before buying or switching devices, check the specific model's compatibility because a phone that takes a SIM card in one country may not have a physical tray in another.
What is a SIM card?
A SIM card is the small card that identifies your phone to a mobile carrier. On supported phones, it is inserted in a SIM tray; on eSIM-capable phones, service can also be activated digitally.
Types of phones that use SIM cards
Most categories of mobile phones use physical SIM cards, though the exact support depends on the device. Feature phones, smartphones, dual-SIM phones, and unlocked phones all commonly include a SIM tray. Dual-SIM phones have two slots, letting you use two different numbers or carriers at once. Unlocked phones are not tied to a specific carrier and can accept a SIM card from any compatible provider.
SIM card compatibility by brand
Apple iPhone
Apple's SIM support page covers physical SIM removal and replacement, so iPhones with a SIM tray use a physical SIM card. Apple says to use only the SIM tray that came with your device; trays are model-specific and may not fit other iPhones. For example, an iPhone 6s SIM tray will not fit an iPhone 7. To check your model's tray location, refer to Apple's model-specific guidance.
Google Pixel
Google's SIM setup page gives steps for inserting a nano SIM in Pixel phones. On Pixel 3, the SIM slot is on the bottom edge, while other supported Pixel phones use the left edge. Some Pixel models are eSIM-only in the US, so verify your specific model's physical SIM support before purchasing. US Pixel 10, Pixel.
Samsung Galaxy
Samsung's support pages cover Nano-SIM installation and dual-SIM use on select Galaxy models. Dual SIM and eSIM support is limited to select Galaxy devices. The SIM card must fit the tray only one way, and the metal-contact orientation varies by device.
