Qoolline eSIM Connection Troubleshooting Guide
If your Qoolline eSIM shows as connected but you aren’t getting Internet access on 4G LTE or 5G, it could be due to several reasons. Below are common issues you might experience:
• Slow download/upload speeds
• “E” (Edge) in the signal status instead of 4G LTE or 5G
• No Internet connection despite showing a network connection
Please follow the steps below to troubleshoot these issues.
IMPORTANT: DO NOT DELETE YOUR eSIM
If your eSIM isn’t working, follow these steps or contact Qoolline support for help. Deleting your eSIM may result in needing to reconfigure your service.
1. Are You in the eSIM Service Area?
• Your Qoolline eSIM will only connect in the purchased destination.
For example, a USA eSIM will only work in the USA.
• You can install the eSIM on your device anytime, but it won’t connect to a network until you arrive in the appropriate service area.
2. Enable Data Roaming
Data roaming must be enabled for the eSIM to connect to the network.
• iPhone / iPad (iOS):
1. Go to Settings > Cellular.

2. Select your eSIM plan under Cellular Plans (e.g., “Secondary” or “Personal”).
3. Ensure “Turn On This Line” is toggled ON.
4. Enable Data Roaming.

• Samsung Galaxy (Android):
1. Open Settings > Connections.
2. Tap Mobile Networks.

1. Open Settings > Connections > Mobile Networks (or Network & Internet on Pixel).

2. Select your eSIM plan > Access Point Names (APN).


3. Tap Menu > New APN.

5. Reset the Data Connection
Try resetting the network connection:
1. Enable Airplane Mode for 30 seconds.

2. Turn off Airplane Mode to reconnect to the network.

3. Wait up to 15 minutes for the eSIM to authenticate and connect to 4G LTE or 5G.
6. Manually Select a Network
If resetting doesn’t work, you may need to select a network manually:
• Apple iOS (iPhone):
1. Go to Settings > Cellular.

2. Select your eSIM plan under Cellular Plans.
3. Tap Network Selection.
4. Switch Automatic to Off and wait for the list of available networks.
