Hi! I see you have a Kolet global plan with 20GB, which was working yesterday in Gabon but stopped working this morning. Let's get this sorted out.

First, to clarify: Are you seeing any network signal or are you completely offline? Also, is your data roaming enabled on your iPhone? Sometimes when traveling internationally, the device needs to have data roaming turned on to connect to local networks.

Meanwhile, here are some quick checks you can do on your iPhone (iOS 18.5):

1. Go to Settings > Cellular > Cellular Data Options, and ensure that Data Roaming is turned ON.

2. In Settings > Cellular, make sure your Kolet eSIM is selected as the active data plan (if you have multiple SIMs).

3. Toggle Airplane Mode ON and then OFF to refresh network connections.

4. Restart your iPhone to reset network settings.

If after these steps you still have no internet, then sometimes the issue could be temporary network coverage or your Kolet plan might have restrictions in Gabon. According to Kolet's info, the global plan should work there, but coverage might vary1 2.

Do you mind checking these settings and letting me know what you observe? That way, I can guide you further!
