Methodology
Speed test methodology
We tested mobile speeds in Taiwan across local carriers using Ookla Speedtest and Fast.com from urban, suburban, and tourist locations. Tests ran at peak (10am-2pm) and off-peak (6am-8am) hours over a seven-day period. Each provider was tested on the same device to eliminate hardware variables.
Results

Infrastructure
Taiwan network infrastructure
Taiwan has 3 carrier networks supporting 5G. Travel eSIM providers route through Taiwan Mobile as the primary network.
| Operator | Technologies |
|---|---|
| Taiwan Mobile | 4G, 5G |
| Chunghwa Telecom | 4G, 5G |
| FarEasTone | 4G, 5G |
Routing
Network partners and carrier routing
| Provider | Carrier Partner | Network Type | Routing |
|---|---|---|---|
| Airalo | Taiwan Mobile | 5G | Tier-1 Direct |
| Holafly | Taiwan Mobile | 5G | MVNO |
| Saily | Taiwan Mobile | 5G | MVNO |
| Nomad | Taiwan Mobile | 5G | MVNO |
All 4 providers route Taiwan eSIM traffic through Taiwan Mobile as the primary network partner. Speed differences between providers stem from prioritization agreements rather than carrier selection.
Tier-1 routed providers (HelloRoam, Airalo) receive the same network priority as local postpaid subscribers. MVNO-routed providers may experience deprioritization during peak congestion windows, resulting in 10-20% lower speeds at peak times.
