Chiaki-ng Over Mobile Data – Remote Play While Traveling
Yes — chiaki-ng works over mobile data and hotel Wi-Fi, as long as your PS5 is reachable over the internet. Register the console over PSN (or set up port forwarding) before you leave, put the console in rest mode with network wake enabled, and budget your bitrate: mobile connections reward conservative settings.
How Much Data Does It Use? (The Math)
Estimate data per hour from your bitrate setting:
| Bitrate setting | ≈ Data per hour | Looks like |
|---|---|---|
| 5 Mbps | ≈ 2.25 GB | 720p, smooth on phone screens |
| 10 Mbps | ≈ 4.5 GB | 1080p-ish, good balance |
| 15 Mbps (default) | ≈ 6.75 GB | Full default quality — heavy on capped plans |
Before You Leave Home
- Register over PSN (not just local discovery) so the console is reachable from outside — see remote play over the internet.
- Enable rest-mode wake: PS5 Settings → System → Power Saving → Features Available in Rest Mode → Stay Connected to the Internet + Enable Turning On PS5 from Network. Full walkthrough: wake & sleep remotely.
- Wire the PS5 to your home router. Your home upload is the bottleneck for the whole trip.
Hotel & Campus Wi-Fi: The Honest VPN Note
Many hotel and campus networks block the ports remote play needs. A VPN won’t make your stream faster — it adds latency — but it can make a blocked network connect at all by tunneling past the firewall. That’s the only honest reason to use one here. Our VPN guide for remote play covers which services to consider and keeps the same honest framing.
Frequently Asked Questions
How much mobile data does chiaki-ng use per hour?
It depends entirely on your bitrate: roughly 2.25 GB/hour at 5 Mbps, 4.5 GB/hour at 10 Mbps, 6.75 GB/hour at the 15 Mbps default. Use the formula bitrate × 3600 ÷ 8 ÷ 1000 to estimate any setting.
Can I play on hotel Wi-Fi?
Sometimes — many hotel networks block remote play ports or throttle UDP. If it won’t connect, a VPN can tunnel past the block (it won’t make it faster, just possible). See our VPN guide.
Will my PS5 wake from rest mode while I’m away?
Yes, if rest-mode network wake is enabled before you leave (Stay Connected to the Internet + Enable Turning On PS5 from Network). Test it once from your phone on mobile data before the trip.
Is 5G latency good enough for action games?
Honestly: fine for slower-paced games, rough for competitive shooters or fighting games. Mobile latency is higher and spikier than home Wi-Fi — set expectations accordingly and stick to 720p.
Does chiaki-ng use more data than Sony’s official app?
Roughly the same at the same bitrate. chiaki-ng’s advantage is the precise bitrate slider (1 Mbps steps), which lets you tune data usage exactly to your plan.
