How to fix Dodo eSIM issues

Fixing Dodo eSIM not working issue is often very easy. Follow these steps to identify the issue and then use the troubleshooting guide specific to your device.

Check if your device supports eSIM

The most common problem why Dodo eSIM is not working is your device. Check if you have an eSIM-compatible phone.

For iPhone

eSIM is supported on all iPhone XS, iPhone XR, and all newer models. Even with a compatible device, you need to make sure your phone is unlocked. So, follow these steps:

Go to Settings > General > About > Network Locks.
You should see “No SIM restrictions”, which means your iPhone is unlocked and can use eSIMs.
To make sure if your iPhone supports eSIM, go to Settings > Cellular > Add Cellular Plan and look for “Add eSIM”.

For Android

Settings options can vary by Android brand. While the exact names of these options might differ, the general procedures will apply to most devices.

Go to Settings > Network & Internet or Connections.
Select SIMs or SIM Card Manager.
Look for an option like Add eSIM, Download SIM, or Add Mobile Plan.
If you find this option, your phone supports eSIM.

Check if your Dodo eSIM QR code has expired

After purchasing a Dodo eSIM, you’ll receive its profile via a QR code, which becomes invalid after scanning. So, if you delete the eSIM, you can’t use the same QR code to activate it again.

How to fix:

Request a new eSIM and QR code from Dodo customer support.
Reinstall the new eSIM on your device.

Turn on mobile data and data roaming

Make sure the data roaming is enabled on the phone.

On iPhone:

Go to Settings > Mobile Data.
Select eSIM.
Turn Data Roaming on.

On Android:

Go to Settings > Connections or Network & Internet > Mobile Network.
Select eSIM
Turn Data Roaming on.

Follow these simple steps to enable roaming on your iPhone.

Enable and disable Airplane Mode

Sometimes the reason for a Dodo eSIM not working is a temporary network glitch. In this case, enabling and disabling Airplane Mode can fix your issue.

Turn on Airplane Mode.
Wait for 30 seconds.
Turn it off.
Restart your phone.

Manually select a local network

Some phones may not automatically connect to the best available partner network. In this case, you need to select a local network manually.

For iPhone:

Go to Settings > Mobile Data > Network Selection.
Turn Automatic network selection off.
Let your phone scan available networks.
Select a network from the list.

For Android:

Go to Settings > Connections or Network & Internet > Mobile Network.
Select Network Operators and turn off Select Automatically.
Wait until your phone finds available networks.
Select a network from the list.

Update or reset your APN settings

APN controls how your phone connects to your carrier’s network. Mobile data may not work if the APN setting is incorrect.

The correct APN settings should be emailed to you together with the activation QR code for your eSIM. After setup, make sure the ones on your phone match the settings provided by Dodo.

Restart your phone after changing APN settings.

Reset your network settings

Resetting network settings can clear hidden misconfigurations and fix wrong settings. This should be a last-resort, as resetting network settings also resets all other connections, such as WiFi and Bluetooth.

iPhone:

Go to Settings > General > Transfer or Reset iPhone.
Select Reset Network Settings.

Android:

Go to Settings > General Management or System.
Select Reset Network Settings.
