When it comes to smartphones, one of the most essential components is the SIM card. It’s what connects your device to the cellular network, allowing you to make calls, send texts, and access the internet on the go. But with the constant evolution of technology, SIM card sizes have changed over the years, leaving many users wondering what size SIM card their device uses. In this article, we’ll delve into the world of SIM cards and explore what size SIM card the Samsung Galaxy Express 3 uses.
The Evolution of SIM Cards
Before we dive into the specifics of the Galaxy Express 3, let’s take a step back and look at the history of SIM cards. SIM cards, or Subscriber Identity Module cards, have been around since the early 1990s. The first SIM cards were the full-size SIM cards, which were the size of a credit card. These were followed by the mini SIM card, which was smaller and more compact. The mini SIM card was the standard for many years, until the introduction of the micro SIM card.
The micro SIM card was even smaller than the mini SIM card, and it quickly became the new standard for smartphones. But as technology continued to advance, an even smaller SIM card was needed. Enter the nano SIM card, which is the smallest SIM card to date. Today, most smartphones use nano SIM cards, but there are still some devices that use micro SIM cards.
What Size SIM Card Does the Galaxy Express 3 Use?
Now that we’ve explored the history of SIM cards, let’s get to the question at hand: what size SIM card does the Samsung Galaxy Express 3 use? The answer is: micro SIM card. Yes, you read that right – the Galaxy Express 3 uses a micro SIM card, not a nano SIM card.
This might come as a surprise to some users, especially since many newer smartphones use nano SIM cards. But the Galaxy Express 3 was released in 2015, a time when micro SIM cards were still the standard. So, if you’re looking to upgrade your SIM card or switch to a new carrier, make sure you get a micro SIM card that’s compatible with your device.
Why Does the Galaxy Express 3 Use a Micro SIM Card?

Micro SIM cards are also thicker than nano SIM cards, which makes them easier to handle and insert into your device.
