Emergency calls
Important: This device operates using radio signals,
wireless networks, landline networks, and user-
programed functions. If your device supports voice calls
over the internet (internet calls), activate both the
internet calls and the cellular phone. The device will
attempt to make emergency calls over both the cellular
networks and through your internet call provider if both

guaranteed. You should never rely solely on any wireless
device for essential communications like medical
emergencies.

strength. Depending on your device, you may also need to
complete the following:
• Insert a UIM card if your device uses one.
• Remove certain call restrictions you have activated in
your device.
• Change your profile from offline or flight profile mode to
an active profile.
