In most cases, your Figabytes eSIM configures network settings automatically. However, if mobile data isn’t working as expected, you may need to check or update your APN (Access Point Name) settings.
This guide explains what APN settings are, when you need to change them, and how to update APN settings on your device.
What Are APN Settings?
APN (Access Point Name) settings tell your device how to connect to the mobile data network.
If these settings are missing or incorrect, your phone may show signal bars but still not connect to the internet.
APN settings control:
Mobile data access
Network routing
Authentication with the carrier
When Should I Change My APN Settings?

Mobile data is not working
