Peak vs Off-Peak Congestion
Every mobile network in Bhutan carries more traffic in the evening and over lunch, and commute hours crowd the towers near transit hubs. All five providers share those towers, so congestion hits them equally. Schedule large downloads and video calls outside those windows.
Indoor Signal Quality
Building penetration varies by carrier and frequency band in Bhutan. Low-band carriers (700 MHz) penetrate buildings effectively. High-band 5G (mmWave) requires line-of-sight and struggles indoors. Mid-band 4G LTE provides a balance of speed and indoor reach. Hotels, restaurants, and shopping centers typically maintain strong signal quality.
Throttling and Fair Use
HelloRoam and Holafly unlimited plans in Bhutan run at full 4G LTE speed until the daily fair-use threshold. After the threshold, speeds reduce. Maps and messaging still work at throttled speeds. Video streaming and large file downloads do not. Fixed data plans from HelloRoam, Airalo, Saily, and Nomad run at full speed until the data allowance is completely used, then stop entirely.
