With the evolution of eSIM technology, staying connected, whether you’re traveling abroad, switching phones, or leaving physical SIM cards behind, has never been more effortless. An eSIM, or embedded SIM, is built directly into your device, allowing you to activate a mobile plan digitally without the need for a physical card.
Whether you’re using an iPhone, an Android phone, or a wearable device like a smartwatch, setting up an eSIM takes just a few minutes. This guide will walk you through everything you need to know: how to set up eSIM on your device, how to get an eSIM QR code, and how to activate service—quickly and securely. Plus, we’ll share helpful tips to make the most out of your eSIM experience.
How to Set Up eSIM on iPhone: A Step-by-Step Guide
Apple has made eSIM activation a seamless part of its user experience, especially in newer models.
Step 1: Check Compatibility
First, make sure your device supports eSIM. Apple introduced eSIM support starting with iPhone XS, iPhone XR, and every model released afterward. To confirm activation status:
- Go to Settings > Cellular > Cellular Plans
- If a plan is listed, an eSIM is already active
Step 2: Obtain an eSIM Plan
Contact your preferred carrier and request an eSIM. Providers like Roam Digi offer instant delivery of eSIM QR codes via email or through their apps. This makes it incredibly simple to activate your line, especially while traveling.
Step 3: Add Your eSIM
- Open Settings > Cellular
- Tap Add Cellular Plan
- Use your camera to scan the QR code
- Choose a label for easy management (e.g., Travel, Work, Personal)
Step 4: Complete Activation
Your iPhone will activate the plan automatically. If you’re using dual SIMs, you’ll be prompted to assign each plan to either data or calls/texts.
Once complete, your iPhone is ready to use. You can manage multiple eSIMs and even switch between them in settings without removing or inserting anything physically. This is particularly helpful for users who travel frequently or have both work and personal numbers.
How to Activate eSIM on Android Devices
Android phones also support eSIM, although the setup may vary slightly depending on the brand and Android version.
Step 1: Verify Compatibility
Phones like the Google Pixel 3 and later, the Samsung Galaxy S20 and newer models, and recent Motorola and OnePlus models support eSIM. To check:
- Go to Settings > Network & Internet > SIMs
- Look for an option to add eSIM or a Mobile Plan
Step 2: Request an eSIM
Contact your mobile carrier and request an eSIM. Roam Digi, for instance, sends the eSIM QR code directly to your inbox for instant access.
Step 3: Install the eSIM
- Open Settings > Network & Internet (or Connections)
- Tap Mobile Network or SIM Manager
- Select Add Mobile Plan or Add eSIM
- Scan the QR code provided
Step 4: Confirm Setup
After scanning, follow the on-screen prompts to assign your new plan. Choose how you want to use it—either for mobile data, calls, or both.
📱 On some Android devices, you may also be able to download an eSIM directly using an activation code. This is handy when QR scanning isn’t an option.
Once configured, your Android phone is ready to operate just like it would with a traditional SIM card—except faster and without the hassle of physical swapping.
How to Activate eSIM on Wearables (Smartwatches)
If you own a smartwatch with cellular functionality, it likely supports eSIM. This means your watch can make calls, stream music, or send texts independently of your phone.
Apple Watch:
- Make sure your iPhone and Apple Watch are paired
- Open the Watch app on your iPhone
- Navigate to Cellular > Set Up Cellular
- Follow your carrier’s prompts to activate the plan
Samsung Galaxy Watch:
- Launch the Galaxy Wearable app
- Tap Mobile Plans > Add Mobile Plan
- Activate using your QR code or via direct carrier link
