The Three Mobile 3internet APN provides a routable public IP to installers who configure it on a Three SIM. Thousands of UK CCTV and remote access installs rely on it. The Vodafone/Three merger puts its future at risk.

The Vodafone merger puts 3internet at risk. Migrate your installs before your sites go dark.
3internet vs standard Three APN
| APN | IP type | Inbound connections |
|---|---|---|
three.co.uk (standard) |
CGNAT — non-routable | Blocked |
3internet |
Public IPv4 — routable | Works |
What the Vodafone/Three merger means
The merger was approved in late 2024. Network integration is underway. Vodafone does not offer an equivalent non-CGNAT APN. Post-merger rationalisation will at some point withdraw 3internet or move it to standard CGNAT. There is no confirmed date — that is the risk.
What breaks when 3internet goes
| Application | Effect after withdrawal |
|---|---|
| Remote NVR access | Broken — monitoring centre cannot connect |
| Monitoring centre IP whitelist | Broken — IP becomes unknown CGNAT address |
| VPN termination | Broken |
| BESS / telemetry dispatch | Broken — aggregator whitelist fails |
Migration options
| Solution | Network-agnostic? | Hardware change? | Cost |
|---|---|---|---|
| Speedroute Core (WireGuard overlay) | Yes | No (most cases) | Fixed monthly |
| Speedroute 4G (new router) | Yes | Yes | Fixed monthly |
| Carrier static IP APN | No | No | Premium per SIM |
Migration steps
- Audit your estate — list all Three SIMs on 3internet APN
- Check WireGuard compatibility — all current Teltonika RutOS devices are compatible
- Request Speedroute Core configs — WireGuard config file per device, import in under 2 minutes
- Pre-notify monitoring centres — provide new Speedroute static IPs before switching
- Switch APN to standard Three or fit Speedroute eUICC SIM
- Verify inbound connectivity from monitoring centre
