Quick Answer
Adequate with redundancy, not reliable as single-point dependency. Dialog 4G is the best mobile network. SLT and Dialog fibre are best fixed broadband. Always maintain a mobile data backup.
Speed by City
| Location | Home Broadband | Mobile 4G |
|---|---|---|
| Colombo 3/7 | 40–100 Mbps | 20–50 Mbps |
| Galle Fort | 20–60 Mbps | 15–35 Mbps |
| Kandy | 15–50 Mbps | 10–30 Mbps |

Dialog Mobile Plans
| Plan | Data | Price |
|---|---|---|
| Basic | 20GB/month | LKR 1,499 (~$4.60) |
| Standard | 40GB/month | LKR 1,999 (~$6.10) |
| Heavy | 80GB/month | LKR 2,999 (~$9.20) |
Redundancy Setup
1. Dialog Fibre home broadband (primary)
2. Dialog 4G SIM in a dedicated hotspot device (backup)
3. Airalo eSIM pre-installed (emergency)
Bottom Line
Dialog 4G SIM + Dialog Fibre + spare hotspot device = handles Sri Lanka's infrastructure reality. Don't rely on accommodation WiFi alone.
