You should pack your XOXO WiFi in your carry-on luggage because:

1. Safety Regulations: Electronic devices, including routers, should be kept in the cabin during the flight due to safety reasons. If a device were to malfunction or overheat, the cabin crew can monitor and respond to any issues more effectively.

2. Airline Security Requirements: Security regulations mandate that electronic devices be transported in the passenger cabin, where they can be more easily accessed and monitored by the crew.

3. Signal Emitting Devices: Devices that emit signals, like WiFi routers, should be turned off or switched to airplane mode during the flight. Carrying your device with you ensures it can be managed properly throughout the journey.

4. Better Protection: Carry-on luggage is handled with more care and is less likely to be damaged compared to checked luggage, where items are subjected to rough handling.

By packing your XOXO WiFi in your carry-on bag, you ensure both the safety and functionality of the device throughout your trip.
