Common Issues with 3Internet and My Troubleshooting Process
| Unique Fix | How I Discovered and Fixed the Issue |
| Switch the PDP Type to IPv4 Only | I noticed connectivity drops when using IPv4/IPv6. Switching the PDP type to IPv4-only in the APN settings made my connection more stable. It solved port forwarding issues too. |
| Utilize an Alternative APN | When 3internet wasn’t reliable, I tried three.co.uk as the APN. To my surprise, it worked better in areas with weaker signals, especially for streaming and browsing. |
| Disable Carrier-Grade NAT (CGNAT) | Using 3internet APN with a public IP caused slow speeds in certain apps. Switching to three.co.uk, which uses CGNAT, improved my connection in those scenarios. |
| Manually Configure DNS Settings | Automatic DNS wasn’t cutting it. I manually set Google’s DNS (8.8.8.8) in my phone’s APN settings, and it fixed issues with websites loading slowly or not at all. |
| Update Device Firmware | I was skeptical, but updating my phone’s firmware resolved compatibility issues with the 3internet APN. After the update, connections were faster and more reliable. |
| Test with a Different Device | To rule out device issues, I tried the SIM in another phone. The internet worked perfectly there, helping me identify that my device’s settings needed further tweaks. |

Without the correct APN configuration, your device may fail to connect, experience slow speeds, or not utilize mobile data properly.
