How to Activate an eSIM on Android Step by Step

Travelling connected no longer means lugging around plastic SIM cards or hunting for a phone shop at the airport. With an eSIM for Android, the whole process happens on your phone in just a few minutes. In this guide, we walk you through how to activate it step by step, so you’re all set before you head off on your trip.

Before you start: check that your Android is compatible

Not all Android phones support eSIM, but the good news is that the vast majority of high-end devices made since 2019 already include it. Before doing anything, check yours:

• Go to Settings → Connections → SIM Manager (or a similar path depending on your manufacturer).
• If you can see the option “Add mobile data plan” or “eSIM”, your device is compatible.
• Alternatively, look up the specifications for your model on the manufacturer’s website.

Device brands such as Samsung Galaxy (S20 onwards), Google Pixel (3 onwards), Motorola Razr, and OnePlus (select models) are usually compatible. If you’re not sure, get in touch and we’ll confirm it for you.

Step 1: Purchase the right eSIM plan for your trip

The first step is choosing a plan that suits your destination and your usual usage. At Roam2Go you’ll find eSIM plans for dozens of countries and regions, ideal for both short getaways and longer trips. Think about how much data you’ll need: if you use your phone moderately for maps, messaging, and social media, a standard plan is usually more than enough. If you’re planning to work remotely or make video calls, it’s worth going for an option with greater capacity.

Once you’ve completed your purchase, you’ll receive an email with a QR code or a manual activation code. Keep it safe — you’ll need it in the next step.

Step 2: Activate the eSIM on your Android

This is where the technical part begins, but don’t worry — it’s much simpler than it sounds.

Option A: Scan the QR code

1. Go to Settings → Connections → SIM Manager.
2. Tap “Add mobile data plan” or “Add eSIM”.
3. Select “Scan QR code”.
4. Point your camera at the QR code you received by email.
5. Follow the on-screen instructions to confirm the addition of the plan.

Option B: Enter the code manually

1. From the same menu, choose “Enter code manually”.
2. Type in the activation code we sent you (it usually follows the SM-DP+ format).
3. Confirm and wait for the device to download the profile.

Important: You’ll need a Wi-Fi connection or mobile data (via your physical SIM) during this step. Do it at home or at work — not at the airport at the last minute.

Step 3: Set which line handles your data

Once the eSIM is installed, your Android has two lines: the physical SIM and the eSIM. To make the most of it:

• Go to Settings → Connections → SIM Manager → Mobile Data.
• Select the Roam2Go eSIM as your preferred data line.
• If you like, you can keep the physical SIM active for calls and SMS on your local number.

This dual SIM setup is one of the great advantages of eSIM: you don’t have to give up your number while you’re abroad.

Final tips to avoid any nasty surprises

• Activate it in advance: Don’t wait until you’re at the airport. Do it 24–48 hours before you leave.
• Don’t scan the QR code from the same phone’s screen: Print it out or use a second device to display it.
• Disable roaming on your physical SIM when you’re at your destination to avoid unexpected charges.
• Check the expected coverage at your destination before buying: each plan lists the supported networks.
• If you run into any issues, the Roam2Go team is on hand to help.

Now that you know how it works, browse all the eSIM plans available at Roam2Go and choose the one that best suits your next trip.
