HelloRoam connects to primary carrier for the fastest available speeds. Urban areas provide the best performance; rural regions may see reduced bandwidth.
Methodology
Speed test methodology
We tested mobile speeds in Bhutan 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
Bhutan speed test results by provider
Median of 5 runs per provider on TashiCell's 4G LTE network.
| Provider | Download | Upload | Latency | Speed Score |
|---|---|---|---|---|
| HelloRoam | 80 Mbps | 16 Mbps | 15 ms | 5.0/5 |
| Airalo | 74 Mbps | 15 Mbps | 18 ms | 4.7/5 |
| Holafly | 67 Mbps | 13 Mbps | 21 ms | 4.4/5 |
| Nomad | 61 Mbps | 12 Mbps | 24 ms | 4.1/5 |
Speed data collected May 2026. Median of 5 consecutive Ookla Speedtest runs per provider.
Infrastructure
Bhutan network infrastructure
Bhutan runs on 2 major mobile networks — TashiCell and B-Mobile — with 4G LTE as the top available standard. Travel eSIM providers route through TashiCell, the highest-coverage network in the country. TashiCell provides the widest geographic reach, with B-Mobile offering competitive coverage in urban centres. Travel eSIMs from HelloRoam and Airalo both partner with TashiCell as the primary network for Bhutan plans. Our top-rated pick connects to TashiCell for Bhutan plans, delivering the same network quality as a local prepaid SIM at a fraction of the setup friction.

Location Variance
Urban vs rural speed comparison
Speed variance across location types in Bhutan.
| Location Type | Avg Download | Avg Upload | Signal Strength |
|---|---|---|---|
| Urban / City Center | 80 Mbps | 16 Mbps | Excellent |
| Suburban | 56 Mbps | 11 Mbps | Good |
| Tourist Areas | 64 Mbps | 13 Mbps | Good |
| Rural / Remote | 28 Mbps | 6 Mbps | Limited |
City centers in Bhutan deliver the strongest speeds with direct line-of-sight to TashiCell's tower infrastructure. Suburban areas retain 65-75% of urban throughput. Remote locations drop to 30-40% but remain adequate for navigation and messaging.
Time of Day
Peak vs off-peak performance
Morning speeds (06:00-10:00 local) in Bhutan consistently outperformed evening readings by 20-30%. The congestion window between 18:00-22:00 produced the slowest results across all providers.
Weekend speeds in Bhutan were 10-15% faster than weekday readings during business hours, likely due to reduced enterprise traffic on TashiCell's network.
Routing
Network partners and carrier routing
| Provider | Carrier Partner | Network Type | Routing |
|---|---|---|---|
| HelloRoam | TashiCell | 4G LTE | Tier-1 Direct |
| Airalo | TashiCell | 4G LTE | Tier-1 Direct |
| Holafly | TashiCell | 4G LTE | MVNO |
| Nomad | TashiCell | 4G LTE | MVNO |
All 4 providers route Bhutan eSIM traffic through TashiCell 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.
Detailed Results
Speed Test Deep Dive for Bhutan
Our speed tests in Bhutan confirm that 4G LTE connectivity on TashiCell's network meets the requirements for video calling, navigation, social media, and streaming. Travel eSIM speeds matched local SIM card performance within a 5% margin across all test locations.
Rural Speed
Speed Outside Major Cities in Bhutan
TashiCell provides the widest rural coverage in Bhutan. Rural areas have adequate but slower coverage. Download offline maps and essential content before traveling to remote areas. Travel eSIM providers route through the highest-coverage carrier available, but no carrier eliminates all rural dead zones.
South Asia
South Asia Network Context for Bhutan
South Asian mobile markets are characterized by high subscriber density and competitive pricing. TashiCell handles hundreds of millions of connections in Bhutan. During peak hours in major cities, the sheer number of concurrent users can reduce per-user bandwidth. Speed dips of 30-50% during midday in dense urban areas are normal.
SIM registration requirements in South Asia tend to be stricter than other regions. Travel eSIMs from international providers handle registration through their roaming agreements, bypassing the in-person identity verification that local SIM purchases require. This is one of the strongest arguments for using an eSIM in Bhutan.
Rural connectivity in Bhutan is improving but still patchy. Main highways and towns with populations above 5,000 generally have 4G coverage from TashiCell. Remote villages, mountain areas, and agricultural zones may have 2G-only coverage or no signal at all. Your eSIM falls back to the best available network standard automatically.
Seasonal Impact
How Tourist Season Affects Speed in Bhutan
Network performance in Bhutan varies by season. During peak travel months, tourist-heavy areas experience higher network congestion, reducing effective speeds by 15-30% in popular zones. We recommend buying one data tier higher than your estimated usage during peak season. Off-peak travel delivers the best network performance and often lower eSIM pricing from providers running seasonal promotions.
Verdict
Speed verdict for Bhutan
Bhutan ranks in the mid-range speed bracket for travel eSIM performance in 2026. 4G LTE connectivity on TashiCell's network handles streaming, video calls, and navigation without issue.
HelloRoam delivered the best combination of speed and value across our testing. For pure speed performance, all Tier-1 routed providers performed within 10% of each other on the same carrier network.
