Frequently Asked Questions

Questions about this plan

Even with unlimited data plans, some networks apply a reasonable usage policy if consumption is very high. To maintain a smooth connection: use the hotel's Wi-Fi for large downloads/updates, avoid automatic cloud backups on 4G/5G, and download maps/playlists in advance. If you experience a slowdown, turn mobile data off and on again, or temporarily switch to 4G in your settings.

Activate the hotspot only when needed, then deactivate it as soon as you're finished. Keep the screen off, plug in your phone if possible, and limit resource-intensive tasks on the connected device (syncing, downloading, updates). Tip: Rename the hotspot and set a strong password to prevent accidental connections.

Before leaving, enable "standard quality" uploads in your apps (Instagram/TikTok/WhatsApp) and disable automatic HD uploads. When network conditions are unstable (train, densely populated areas), upload over Wi-Fi or save your videos as drafts and upload them later. For playback, lower the quality in the app if buffering is excessive: this will improve smoothness without interrupting playback.
