Check your city Mobitel 5g coverage
Finding a reliable 5G signal can be a bit of a moving target, especially since SLT-Mobitel expands its pre-commercial 5G trial network in phases across major urban hubs. While the official network covers select high-density zones, finding a live, street-level coverage map requires looking at both official portals and crowd-sourced telecom trackers.
Here is how you can find and use the available Mobitel 5G coverage maps to check if your neighborhood is covered.
Methods to Find the Mobitel 5G Coverage Map
| Method Type | Platform / Source | Best For | What You’ll Find |
| Official Map Portal | SLT-Mobitel 5G Web Link | Real-time planned coverage zones | The definitive list of officially activated 5G test sites and commercial trial locations across the island. |
| Crowd-Sourced (Live) | nPerf Interactive Map | Real-world, user-tested coverage | Interactive map showing actual, user-submitted 5G signal pings in Sri Lanka. Updated hourly. |
| Advanced Signal Tracker | CellMapper (Sri Lanka) | Tower locations & band data | Pinpoints exact cellular towers, active sector frequencies, and estimated 5G signal propagation. |
Pro-Tip on Mobitel 5G: Even if you are standing directly inside a 5G zone on the map, your phone won’t connect unless your device is officially white-listed or approved by the network for their 5G trial, and your network mode is set to “5G preferred”. Mobitel currently offers a free 10GB 5G monthly trial data bundle to users who successfully connect to these trial zones.
