Before you try any of our other steps:

• Confirm your phone supports eSIM
• Make sure your phone is unlocked
• Update your phone software (latest iOS/Android)
• Use strong Wi-Fi when installing the eSIM
• Turn Airplane Mode ON for 10 seconds, then OFF
• Restart your phone

• Increase screen brightness (on the device showing the QR)
• Make the QR bigger (zoom in)
• Avoid glare / reflections
• Hold the camera steady and let it focus

If scanning fails, use manual installation via the link provided in your email, or via your FlexySim account

This usually means the eSIM has already been installed to your device.

To check if you eSIM has already installed:

iPhone

Settings → Mobile/Cellular

Look under SIMs / Cellular Plans.

Android

Settings → SIM Manager / SIMs

Look for an eSIM plan in the list.

Most FlexySim eSIMs are single use, if you have installed, and deleted an eSIM by mistake, please contact our support team for assistance.

You have signal bars, but nothing loads

This is usually solved by turning on roaming and ensuring you have selected your FlexySim eSIM as the data line.

Step 1 — Turn ON Data Roaming (Required for most travel eSIMs)

iPhone:

Settings → Mobile/Cellular → FlexySim → Data Roaming → ON

Android:

Settings → Connections/Network & Internet → Mobile Network → Data Roaming → ON

Step 2 — Set FlexySim as your Mobile Data line

iPhone:

Settings → Mobile/Cellular → Cellular Data → FlexySim

Android:

SIM Manager → Mobile Data → FlexySim

Step 3 — Toggle Airplane Mode

Turn Airplane Mode ON for 10 seconds → then OFF.

Step 4 — Restart your phone

A restart forces the device to reconnect properly, and often fixes most connection issues.

If you see No Service, SOS, or no network signal:

Step 1 — Confirm you’re in the correct destination

Make sure the FlexySim plan you purchased matches your current country/region. Your eSIM will only work in the region selected for your eSIM

Step 2 — Manually select a network

Sometimes the phone connects to the wrong network automatically. If this occurs, manually select a network for connection

iPhone:

Settings → Mobile/Cellular → FlexySim → Network Selection → turn OFF Automatic → try available networks

Android:

Settings → Mobile Network → Network Operators → turn OFF Auto → select an available network

Step 3 — Airplane Mode + Restart

Sometimes all it takes is a simple restart to find the right network.

• Toggle Airplane Mode (10 seconds)
• Restart your phone
  

FlexySim eSIMs are data-only, so the Apple iMessage service should still work without any issues— but switching data lines can sometimes cause confusion.

If you have trouble using iMessage, try these steps

1. Settings → Messages → Send & Receive
   
2. Ensure your Apple ID/phone number is selected correctly
   
3. Keep your primary SIM active for iMessage identity (if needed), however only set your FlexySim eSIM for data to ensure you avoid data roaming charges with your usual SIM
