How do I resolve the 'Unable to Complete Cellular Plan Change' error when using Qoolline eSIM on my iOS device?

Encountering an "Unable to Complete Cellular Plan Change" error on your iOS device can be frustrating, especially if you’re updating or changing your Qoolline eSIM plan. This error often occurs due to a communication issue between your device and the cellular network, or if there’s a problem with the eSIM configuration. Here are some simple steps to troubleshoot and resolve this issue, ensuring uninterrupted connectivity on your device.

1. Too Many eSIMs on Your Device:
Some devices have limits on the number of eSIMs they can store. For example, iPhones can manage around 5 to 10 eSIM profiles based on the model. If you've reached this limit, remove any old or unused eSIM profiles to make room for your new Qoolline eSIM. Refer to "How to Remove an eSIM from Your Device" for detailed instructions.

2. Cellular Data Turned Off:
Ensure that cellular or mobile data is enabled in your device’s settings. Go to Settings > Cellular and make sure it’s turned on. This setting is crucial for eSIM functions.

3. Reinstalling an Already Installed eSIM:
Most eSIMs can only be installed once. To check if your Qoolline eSIM is already on your device, navigate to Settings > General > About and look for the ICCID number. If the eSIM is present, you may only need to adjust settings instead of reinstalling. For specific installation steps, refer to your Qoolline eSIM installation guide.

4. Weak Internet Connection During Installation:
If you’re using a slow or unstable internet connection, such as public Wi-Fi or a ship’s network, the eSIM setup may not complete. Switching to a reliable, stable network can help avoid this issue.
