Setup:

1. Install eSIM before event
2. Test speed in venue
3. Enable personal hotspot
4. Connect laptop/tablet

Expected Performance:

• 4G: 10-50 Mbps (sufficient for Zoom)
• 5G: 100-300 Mbps (4K video capable)

Backup Plan:

• Carry pocket WiFi as tertiary backup
• Download offline presentation materials
• Test video call quality day before
