Want to switch to the powerful Galaxy S21 or the soon-to-be-launched S22 series?

That's a brilliant decision. These phones are sleek, powerful, and fun to use. But can you insert a SIM card and customize SIM settings on these phones? As dumb as it sounds, most users are green on this subject matter.

If you must enjoy a smooth experience during calls, browsing, and messaging, learning how to install a SIM card and customizing settings on your Galaxy S21 or S22 phone isn't an option. So in this post, I'll furnish you with the steps to insert and change SIM settings. That's not all; you'll learn to transfer all data from your old phone to your brand-new Samsung phone. Let's dig in!

Part 1. The supported SIM card size for Galaxy S21/S22

First and foremost, the Samsung Galaxy S21 series supports the convenient dual SIM model. In other words, this phone supports two nano-SIM cards that you can conveniently switch between. Each SIM card allows users to keep a separate contact list, block calls, messages, etc. And the new S22 series will house the same combination.

Meanwhile, the nano-SIM is the smallest of all physical SIM cards. It measures 12.30x0.67mm, which is way smaller than the 15.00x0.76 mm micro-SIM. The standard SIM is the largest, measuring 25.00X0.76mm. However, most high-end smartphones, including iPhones, use the nano-SIM setup.

But regardless of the SIM type, the network performance remains the same across most smartphones. Of course, the network speed and charges are hugely dependent on your network vendor and location. In short, a smaller SIM type only saves space!

Part 2. Does Galaxy S22 support eSIM, and how to use eSIM on Galaxy S21/S22?

Yes, both phones offer additional e-SIM support apart from the dual nano-SIM mode. An e-SIM is a SIM card like any other, just that it comes baked inside your new smartphone. Put, and it's not a SIM card that you can touch and see unless you tear up the phone. Today, more tablets, smartphones, and laptops embrace this technology as it's more convenient to use than traditional SIM cards.

But how does an e-SIM work? Simple, you only need to install the e-SIM profile provided by your network carrier. This makes e-SIM better than traditional SIM cards, being that you can easily switch between mobile network subscriptions. Popular e-SIM networks include T-Mobile, Verizon Wireless, Vodafone Idea, AT&T, Airtel, and Ubigi.

It's also worth saying that smartphones aren't the only devices that support e-SIMs. For example, smartwatches like Galaxy Watch and Apple Watch support cellular connection via e-SIM. Moreover, some laptops like Surface Pro 6 and Surface Pro 7 have e-SIM capabilities.

Ways to activate e-SIM on Samsung Galaxy S21/S22:

  • Step 1. Open the Settings app and launch the SIM card manager window under Connections.
  • Step 2. Next, press the Add mobile plan button and tap Ok. SIM 2 will automatically be disabled to allow room for e-SIM.
  • Step 3. Tap Scan carrier QDR code and scan the code you got from your carrier network.

Part 3. How to insert, change, and use two SIM cards on Galaxy S21/S22?

So, you've finally paid top dollar for the dream Samsung Galaxy S21 or S21? Good! But with no SIM card inserted in Samsung, you can't enjoy the benefits of calling, texting, setting up chat apps, and so on. So, without wasting time, let's hunker down and learn how to put a SIM card in Samsung Galaxy S21 or Galaxy S21. Follow me!

How to put a SIM card in Samsung Galaxy S21/S22:

  • Step 1. First, unbox the smartphone and get the SIM card tray ejector or pin. Then, go to the phone's bottom and eject the SIM tray.
  • Step 2. You'll see SIM 2 and SIM 2 on the top and bottom sides of the SIM tray. So, insert your SIM 1 and SIM 2 and slot the tray back inside the phone.
  • Step 3. Now fire up the phone and enter a SIM PIN, if any, to access the device. You can now head to the SIM card manager window, where you'll see your two active SIM cards.

How to change SIM card settings in Galaxy S21/S22:

  • Step 1. After successfully inserting the SIM cards, open the Settings app and tap Connections.
  • Step 2. Tap SIM card manager to view the inserted SIM cards with sliders next to each SIM. If you want to use or disable a single SIM, tap the toggle next to the SIM that you don't want to use.
  • Step 3. Now scroll down to preset a SIM card for calls, messages, or mobile data. You can even personalize the SIM card color and name for seamless identity.
  • Step 4. If successful, follow the on-screen instructions to complete the e-SIM setup.

Pro tip: You can easily switch between cards without opening the settings window. Just open the Notifications panel and select a card.

Part 4. Different types of SIM card trays for Samsung phones?

So, what type of SIM trays can you find in a Samsung phone or any other smartphone for that matter? There are three main types of SIM trays. The first and the most common is the dual SIM tray, which you'll find on Galaxy S21 and S22 series. You'll get a space for SIM 1 at the top and a position for SIM 2 at the bottom in this compact model. So, insert your two SIMs and enjoy.

Some older Samsung phones use a single SIM setup. As the name hints, these phones can only support a single SIM card, which is inconvenient. And then, there is the hybrid SIM type, which supports a single/dual SIM and a microSD slot. This SIM card setup is better, although most smartphone developers no longer keep expandable external memories.

Part 5. Use MobileTrans to transfer phone data to Galaxy S21/S22
