What Is an eSIM, and Why Does It Matter?

An eSIM (embedded SIM) is a digital version of the physical SIM card you’d normally pop into your phone. Instead of a small plastic chip, your eSIM is built directly into your phone’s hardware. You activate a carrier plan by downloading a profile digitally — no trips to the store, no waiting for a card in the mail.

The Pixel 10 supports both a physical nano-SIM and an eSIM, so you can actually run two numbers on one phone. That’s useful if you travel internationally, want to keep a work number separate from your personal one, or want to switch carriers without the extra steps.


Before You Start: What You’ll Need

Don’t jump into the setup blind. Check these things first:

  • A compatible carrier: Not every carrier supports eSIM. In the US, major carriers like T-Mobile, AT&T, Verizon, Google Fi, and Visible all support it. Outside the US, check with your local provider.
  • An active internet connection: You’ll need Wi-Fi or mobile data to download the eSIM profile.
  • Your QR code or activation details: Your carrier will give you either a QR code to scan or a manual activation code. Get this ready before starting.
  • Your account credentials: Some carriers ask you to log in to verify your identity during setup.
  • Pixel 10 running the latest software: Go to Settings → System → System Update and make sure your phone is up to date.

How to Activate eSIM on Pixel 10: step-by-step

Method 1: Activate eSIM Using a QR Code (Most Common Method)

Activate eSIM Using a QR Code (Most Common Method)

This is the method most carriers use, and it’s the most straightforward. Here’s how it works:

Step 1: Open Settings

Unlock your Pixel 10 and go to the Settings app. You can swipe down from the top of the screen and tap the gear icon, or find Settings in your app drawer.

Step 2: Go to Network & Internet

Tap on Network & Internet. This is where all your SIM and connectivity options live.

Step 3: Tap on SIMs

You’ll see a section called SIMs. Tap on it. If you already have a physical SIM installed, it’ll show up here. You’ll also see an option to add a new SIM.

Step 4: Tap “Add SIM” or the “+” Icon

Look for the ” Add SIM or a small + button at the top right. Tap it.

Step 5: Choose “Download a SIM Instead?”

The phone will ask if you want to use a physical SIM or download one. Tap Download a SIM instead, or Scan carrier QR code, depending on what appears on your screen.

Step 6: Scan Your QR Code

Your phone’s camera will open. Hold the QR code your carrier gave you in front of the camera until it scans. If you’re setting up a carrier like Google Fi, you might be taken to an app-based flow instead.

Practical example: Say you’re switching to T-Mobile. After you order an eSIM online, T-Mobile sends you an email with a QR code. You print it out (or open it on another device), then scan it with your Pixel 10. Done.

Step 7: Confirm and Activate

Once the profile downloads, you’ll get a confirmation screen. Tap Activate or Confirm. The Pixel 10 will take a moment to connect to the carrier network.

Step 8: Set Your Preferences

After activation, you can choose which SIM to use for calls, texts, and data. Go back to Settings → Network & Internet → SIMs and set your preferences.


Method 2: Activate eSIM Without a QR Code (Manual Entry)

Some carriers — especially smaller MVNOs or international providers — don’t use QR codes. They’ll give you a manual activation code instead. Here’s how to enter it:

  1. Go to Settings → Network & Internet → SIMs
  2. Tap Add SIM
  3. When the camera opens for QR scanning, look for an option that says Enter code manually or Use code instead.
  4. Enter the activation code your carrier provided (it usually looks like a long string of numbers and letters)
  5. Tap Activate

Method 3: Set Up eSIM During Initial Pixel 10 Setup

 Set Up eSIM During Initial Pixel 10 Setup

If you’re setting up a brand-new Pixel 10 for the first time and you already have an eSIM plan ready, you can activate it right during the initial phone setup — before you even reach the home screen.

During the setup wizard, your Pixel 10 will ask how you want to connect. Choose Download a SIM and follow the on-screen steps. If you’re transferring from another Android phone that already has an eSIM, the Pixel 10 may even prompt you to move it over automatically using Tap to Transfer.


How to Transfer an eSIM from Your Old Phone to Pixel 10

Upgrading from an older Pixel? You might be able to transfer your eSIM directly.

  1. Keep your old phone nearby and powered on.
  2. During Pixel 10 setup (or from Settings → System → Backup), choose Copy data from old device
  3. If your carrier supports eSIM transfer, you’ll see an option to move the SIM profile.le
  4. Follow the prompts on both devices — they’ll communicate via Bluetooth.NFC

Important: Not all carriers allow eSIM transfers. T-Mobile and Google Fi support it. Some others may require you to deactivate the old eSIM first and issue a new one for your Pixel 10.


Managing Multiple SIMs on Pixel 10

One of the nicest things about the Pixel 10’s dual SIM setup is how clean the management interface is. Once you have both a physical SIM and an eSIM (or two eSIMs) active, here’s how to manage them:

  • Go to Settings → Network & Internet → SIMs
  • Tap on each SIM to rename it (e.g., “Work” and “Personal”), assign a color, and set defaults
  • Under Calls, Texts, and Mobile Data, choose which SIM handles what
  • You can also turn on Ask every time for calls, which prompts you before each call to choose which number you’re calling from

Real-world scenario: You’re traveling to Europe. You keep your US AT&T SIM as your primary for calls and texts back home, and you activate a local eSIM from a European carrier (like Airalo or Holafly) for cheaper local data. Your Pixel 10 handles both seamlessly.


Pros and Cons of Using eSIM on Pixel 10

Pros

No physical SIM swapping: You don’t need to find a SIM ejector tool or worry about losing a tiny card. Switching carriers is done in Settings.

Dual SIM made easy: Run two lines — personal and work, or local and travel — on one device without any hardware changes.

Faster carrier switching: If your current carrier has bad coverage in a new city, you can switch to a different carrier’s eSIM plan in minutes.

More secure: A physical SIM can be removed and used in another device. An eSIM is tied to your phone, which makes SIM-swapping fraud harder to pull off.

Better for travel: International eSIM providers like Airalo, Nomad, and Holafly let you buy a data plan for your destination before you even board the plane.

Cons

Not every carrier supports it: Rural carriers and some international providers still haven’t fully adopted eSIM. You might be stuck with a physical SIM if your carrier isn’t compatible.

Harder to switch phones quickly: If your Pixel 10 breaks and you need to put your SIM in a backup phone, you can’t just pop out the eSIM. You’ll need to contact your carrier to transfer the profile, which takes time.

Profile limits: Most phones (including the Pixel 10) can store multiple eSIM profiles, but only a limited number can be active simultaneously. If you collect a lot of travel eSIMs, you may need to delete old ones.

Internet required to activate: You can’t activate an eSIM if you’re in a dead zone with no internet access. This is rarely a problem, but it’s worth knowing.


Common Problems and How to Fix Them

eSIM Not Activating

  • Double-check that your carrier supports eSIM on the Pixel 10 specifically
  • Make sure your QR code hasn’t expired (most are single-use and time-limited)
  • Restart your phone and try again
  • Contact your carrier — sometimes the profile needs to be reissued on the eend en.d

QR Code Won’t Scan

  • Try opening the QR code on a different device or printing it on paper
  • Make sure your camera lens is clean
  • Adjust lighting — scanning in direct sunlight or a very dark room can cause issues
  • Use the manual code entry option instead

No Signal After Activation

  • Go to Settings → Network & Internet → SIMs and make sure the eSIM is toggled on
  • Tap the eSIM and check if Roaming is enabled (if you’re traveling)
  • Try toggling Airplane Mode on and off
  • Check if your carrier has any outages in your area

If you want to remove an eSIM profile you’re no longer using:

  1. Go to Settings → Network & Internet → SIMs
  2. Tap on the eSIM you want to remove

FAQs

Can I use two eSIMs at the same time on the Pixel 10?

The Pixel 10 supports Dual SIM Dual Standby (DSDS). You can have one physical SIM and one active eSIM, or in some configurations, two eSIM profiles active at once. Check your carrier’s compatibility for the second eSIM option.

Does activating an eSIM cost anything?

The eSIM activation itself is usually free. You’re paying for the plan or service, not the digital SIM. Some carriers charge a one-time SIM setup fee — check with your provider.

Will my eSIM work if I travel abroad?

It depends on your plan. Many domestic eSIM plans include international roaming, but the rates can be high. For travel, it’s often better to add a separate travel eSIM from providers like Airalo and keep your home eSIM active for calls and texts.

Can I have multiple eSIM profiles saved on my Pixel 10?

Yes. The Pixel 10 can store several eSIM profiles, though only a limited number can be active simultaneously. You can switch between stored profiles in Settings.

What happens to my eSIM if I sell my Pixel 10?

Before selling, delete all eSIM profiles from Settings → Network & Internet → SIMs. You should also contact your carrier to deactivate the eSIM on their end and request a transfer to your new device.

Is eSIM safer than a physical SIM?

Generally, yes. Since an eSIM is embedded in your phone and can’t be physically removed, it’s harder for someone to steal your number by swapping the SIM into another device. That said, it’s not completely immune to account-level attacks, so keep your carrier account credentials secure.

My carrier gave me a QR code, but it says it’s already used. What do I do?

QR codes for eSIM are usually single-use. If it shows as already used, contact your carrier and ask them to generate a new one. This sometimes happens if the activation was interrupted midway.

Can I switch back to a physical SIM after using eSIM?

Yes. You can disable or delete your eSIM at any time and use your physical SIM slot. Your Pixel 10 will fall back to the physical SIM for calls, texts, and data.


Conclsion

Setting up an eSIM on your Pixel 10 is one of those things that sounds more complicated than it actually is. Once you’ve done it once, you’ll wonder why you ever bothered with physical SIM cards. The whole process — from scanning the QR code to being fully connected — usually takes under five minutes.

The biggest things to keep in mind: make sure your carrier supports eSIM, have your QR code or activation details ready, and keep your Wi-Fi on during setup. After that, the Pixel 10 does the heavy lifting.

Whether you’re a frequent traveler loading up on international eSIMs, someone who wants to separate work and personal lines, or just someone who lost one too many tiny SIM cards, eSIM on the Pixel 10 is genuinely worth using
