How many SIM cards does the iPhone 12 mini support?
Using multiple SIM cards (most commonly 2 SIM cards) on a single device has become widespread and familiar to users for quite some time (around the year 2007). Most popular Android smartphones from brands like Oppo, Huawei, Samsung, Xiaomi, etc., come equipped with dual SIM dual standby functionality.
Apple's iPhone devices, however, integrated this feature later than other phone manufacturers. It wasn't until 2018 that Apple introduced dual SIM support with the iPhone Xr / XS / Xs Max series, and since then, all iPhone models released by Apple have supported dual SIM functionality.
The iPhone 12 mini is no exception in Apple's journey of upgrading phone features to align with the company's trends. The iPhone 12 mini available in markets is equipped with 2 SIM cards: 1 nano SIM and 1 eSIM. Additionally, the iPhone 12 mini supports high-speed 5G mobile network connections.

In certain markets like China, the iPhone 12 mini won't feature eSIM but instead will have a physical SIM card slot.
Exploring nano SIM and eSIM on the iPhone 12 mini
The Nano SIM, also known as a physical SIM, is a traditional SIM card made of rectangular plastic that many people in Vietnam use. The Nano SIM functions like a smart memory card, storing information such as phone numbers, network codes, personal numbers, and other necessary data.

On the other hand, eSIM is an electronic SIM card with a very small size, directly integrated into the phone's motherboard and has all the functions of a normal SIM card. This is a design trend for replacing traditional plastic SIMs with smaller ones. The convenience of using eSIM is that if you're locked to one network, you can reprogram it to link with other networks. Or if you want to switch from one network to another, you just need to swap the eSIM card and select the network without needing to buy a new SIM card.
The advantages of having 2 SIM cards on the iPhone 12 mini are:
– Using 2 phone numbers on the same smartphone, so you can serve multiple calling purposes. For example, one for work and one for contacting friends or family.
– Take advantage of the best deals from network providers.
– Still maintain communication when one of the two networks encounters issues.
