Mobile Hotspot NAT Type: Fix Strict NAT, NAT Type 3 and NAT D on PS5, Xbox and Switch
Why consoles get NAT Type 3, Strict or NAT D on a phone hotspot, what it breaks on PS5, Xbox and Switch, why phone and console settings cannot fix it, and how a VPN on a travel router or laptop gets Moderate or Open NAT.
Quick Answer
On a phone hotspot, consoles usually show NAT Type 3 or “Failed” on PS5, Strict on Xbox and D or F on Switch, because most mobile carriers use carrier-grade NAT (CGNAT). Phones offer no UPnP or port forwarding for hotspot devices, and console settings cannot change the carrier’s NAT. To fix it, put a VPN with Moderate NAT (Proton) or port forwarding (PureVPN) on a travel router or laptop between the hotspot and the console.
On a mobile hotspot your console usually gets a strict NAT: NAT Type 3 or “Failed” on PS5, Strict on Xbox, D or F on Switch. Most mobile carriers put phones behind carrier-grade NAT (CGNAT), so no one can connect in to you, and party chat, invites and hosting break.
Nothing on the phone or console changes that. Phones do not offer UPnP or port forwarding for hotspot devices, and EA says that on 4G/5G CGNAT, port forwarding won’t work. The fix is to move the NAT somewhere you control: a VPN with Moderate NAT or open ports, running on a travel router or laptop between the hotspot and the console.
Quick Check: Is the Hotspot the Cause?
- Run the NAT test on the console while on the hotspot.
- Run it again on a home or friend’s Wi-Fi with UPnP on.
- Strict only on the hotspot: the carrier’s CGNAT is the cause.
- Strict everywhere: check the console’s own network settings first.
From a laptop on the hotspot, the NAT type test shows the NAT your carrier gives you.
Hotspot NAT Type on PS5, Xbox and Switch
| Device | What you see on a hotspot | What it means |
|---|---|---|
| PS5 / PS4 | NAT Type 3, or “NAT type: Failed” in the connection test | Party chat and joining friends fail; some games refuse to matchmake |
| Xbox Series X|S / One | Strict NAT, “UPnP not successful”, Teredo unable to qualify | Party chat, invites and many multiplayer games fail |
| Nintendo Switch / Switch 2 | NAT Type D or F, or the NAT test fails | You can only match with some players, or none |
| Gaming PC or laptop | Strict NAT in games that report it | Voice, lobbies and peer-to-peer connections fail |
Free Fixes People Try, and Why They Fall Short
Settings on the phone
Changing DNS or MTU on the console
Another phone on the same carrier
If you will be back on home Wi-Fi soon, waiting is free. If the hotspot is your only internet, in a dorm, on the road, or on a 5G plan, these fixes will not get you past Strict NAT.
Fix Hotspot NAT Type With a VPN
A VPN tunnels your games through the carrier’s CGNAT, and the VPN server does the NAT instead. Choose a VPN that sets that NAT to Moderate or opens ports on it; a standard VPN stays Strict.

A VPN app on the phone may not cover devices connected to its hotspot, so put the VPN on the router or laptop. VPN data counts against your mobile allowance, and every VPN adds a little latency: pick the nearest server. Some publishers, such as EA, do not support VPNs officially.
