How to Set Up an eSIM on iPhone & Android

Setting up an eSIM takes less than 5 minutes. This guide walks you through the entire process for both iPhone and Android, plus troubleshooting tips if something goes wrong.

Before You Start: Check Compatibility

iPhone eSIM Support

• iPhone XS, XR, and all newer models
• iPhone SE (2nd generation and later)
• Must be carrier-unlocked

Android eSIM Support

• Samsung Galaxy S20 and newer
• Google Pixel 3 and newer
• OnePlus, Xiaomi, and other brands (varies by model)
• Must be carrier-unlocked

Important: Your phone must be carrier-unlocked. If you bought it through a carrier on a payment plan, contact them to unlock it before your trip.

Step 1: Purchase Your eSIM Plan

1. Choose a provider (we recommend comparing plans on Navi)
2. Select your destination and data plan
3. Complete the purchase — you'll receive a QR code or activation details via email

Step 2: Install on iPhone

Method A: QR Code (Most Common)

1. Open Settings → Cellular (or Mobile Data)
2. Tap Add eSIM or Add Cellular Plan
3. Tap Use QR Code
4. Scan the QR code from your provider
5. Tap Continue and wait for activation
6. Label it (e.g., "Japan Travel")
7. Choose it as your data line

Method B: Manual Installation

1. Open Settings → Cellular
2. Tap Add eSIM → Enter Details Manually
3. Enter the SM-DP+ address and activation code from your provider
4. Tap Next and wait for activation

Step 3: Install on Android

Samsung Galaxy

1. Open Settings → Connections → SIM Manager
2. Tap Add eSIM
3. Tap Scan QR code from service provider
4. Scan your QR code
5. Confirm and wait for download
6. Enable the eSIM for mobile data

Google Pixel

1. Open Settings → Network & Internet → SIMs
2. Tap + (Add)
3. Tap Download a SIM instead
4. Scan the QR code
5. Confirm installation
6. Set as data SIM

Step 4: Configure Your Settings

After installation, configure these settings for the best experience:

Set Data Line

• Go to Settings → Cellular (iPhone) or SIM Manager (Android)
• Set your eSIM as the Mobile Data line
• Keep your home SIM for calls/SMS if needed

Enable Data Roaming

• Settings → Cellular → tap your eSIM → enable Data Roaming
• This is required for most travel eSIMs to work

Turn Off Home SIM Data

• Disable data on your home SIM to avoid accidental roaming charges
• Keep it active for calls/texts only

Step 5: Activate at Your Destination

Some eSIMs activate instantly, others activate when you arrive:

• Instant activation: Works immediately after installation (Airalo, Nomad)
• Destination activation: Activates when you connect to a local network (some Holafly plans)

Pro tip: Install your eSIM 1-2 days before your trip. This way, if there are any issues, you have time to contact support.

Troubleshooting Common Issues

"eSIM Cannot Be Added"

• Ensure your phone is carrier-unlocked
• Check you have a stable Wi-Fi connection
• Restart your phone and try again

"No Service" After Installation

• Enable Data Roaming (most common fix)
• Toggle Airplane Mode on/off
• Manually select a network: Settings → Cellular → Network Selection → Manual

Slow Speeds

• Move to an area with better coverage
• Toggle Airplane Mode on/off to reconnect
• Check if you've exceeded your data limit

QR Code Won't Scan

• Ensure good lighting and hold steady
• Try the manual installation method instead
• Screenshot the QR code and scan from another device's screen

Frequently Asked Questions

Can I use eSIM and physical SIM at the same time? Yes! This is called Dual SIM. Your physical SIM handles calls/texts from your home number, while the eSIM provides local data.

Will I lose my eSIM if I restart my phone? No. The eSIM stays installed through restarts. You only lose it if you manually delete it.

Can I reuse my eSIM on another trip? Most travel eSIMs are single-use. You'll need to purchase a new one for your next trip.

How many eSIMs can my phone store? iPhone can store 8+ eSIMs (but only one active at a time alongside a physical SIM). Android varies by model.
