APN Configuration Guide for All Carriers

APN (Access Point Name) settings tell your phone how to connect to the mobile data network. Most Roambit eSIMs configure APN automatically, but sometimes manual configuration is needed.

When Do You Need to Set APN Manually?

• Your eSIM connects to a network but data doesn't work
• You see signal bars but can't browse the internet
• You received specific APN instructions from Roambit Support

Troubleshooting APN Issues

• Can't edit APN: Some carrier profiles lock APN settings. Try resetting network settings.
• APN resets after restart: Re-enter the APN and ensure you've saved it properly.
• Still no data after APN change: Try switching between IPv4 and IPv4/IPv6 in the APN Protocol setting.
• Multiple APNs listed: Make sure you select the Roambit APN as the active one, not a leftover from a previous SIM.
