Frequently Asked Questions
Why is my data roaming not working even when it's enabled?
Even with data roaming enabled, issues can occur due to network compatibility, carrier restrictions, or account settings. Try manually selecting a different network or contacting your carrier to verify your account is properly set up for international roaming.
Can I use WiFi calling if my roaming doesn't work?
Yes, WiFi calling allows you to make and receive calls over WiFi instead of cellular networks. Enable WiFi calling in your phone settings before traveling, and you can use it whenever connected to WiFi, even if roaming isn't working.
Will a network reset delete my data?
A network reset will not delete your photos, apps, or personal files. It only removes saved WiFi networks, Bluetooth connections, and cellular settings. You'll need to reconnect to WiFi networks and re-pair Bluetooth devices after the reset.
Is roaming or eSIM better for international travel?
For most travelers, eSIMs offer better value, reliability, and convenience than international roaming. eSIMs typically cost less, can be set up in advance, and eliminate the troubleshooting headaches often associated with roaming. However, roaming may be simpler for very short trips if your carrier offers reasonable rates.
