Speed Under Fair Use Policies
Holafly unlimited plans in Thailand run at full 5G speed until the daily fair-use threshold. After the threshold, speeds reduce. Maps and messaging still work.

Matrix analysis
Thailand Scoring Matrix: Dimension-by-Dimension Analysis
The Thailand feature matrix scores 5 providers across 5 equal-weight dimensions. Here is what the numbers mean in practice.
Coverage: Thailand's 3-operator market (AIS, DTAC and True Move) creates real differentiation. Providers routing through the dominant carrier gain a coverage edge in rural areas. HelloRoam scores 4.5/5 on our rubric, Nomad scores 3.9/5.
Network: Thailand runs on 5G. Since all providers route through the same infrastructure, network scores track the carrier tier, not the provider. Pricing: plans start at $3.49 (1GB), $3.49/GB floor rate. Unlimited daily data from $3.49/day shifts the pricing calculus for heavy users. Overall spread: 0.49 points between #1 (HelloRoam) and #4 (Nomad). Provider selection matters significantly in Thailand.
Use cases
Matching Providers to Activities in Thailand
Score-weighted recommendations for Thailand travelers.
Video Streaming
Airalo
Airalo is the strongest pick for streaming in Thailand. Network Generation score: 4.4/5 on our rubric on Thailand's 5G network via AIS, DTAC and True Move. 5G handles HD streaming where the signal is strong. Holafly's unlimited tier from $3.49/day avoids mid-stream data caps.
Remote Work
HelloRoam
HelloRoam ranks first for remote work in Thailand. Video calls need a steady connection more than a fast one. Thailand's 5G network carries video calls where signal is strong. A real-time support channel matters when connectivity drops mid-session. HelloRoam: 24/7 support. Thailand's excellent WiFi supplements eSIM data for stationary work.
Social Media
HelloRoam
HelloRoam fits social-heavy travelers in Thailand. Instagram browsing runs 100-200 MB per hour and TikTok 300-500 MB per hour. At Thailand's floor rate of $3.49/GB, an hour of TikTok scrolling costs roughly $1.70 on the entry tier. App quality score: 5.0/5 on our 2026 rubric for data monitoring while uploading.
Navigation
Airalo
Airalo leads for navigation use in Thailand. Google Maps uses 10-15 MB per hour of active navigation. Coverage is the dominant factor: losing signal mid-route is worse than slow speed. Airalo routes through DTAC in Thailand. Multi-operator market: carrier reach outside urban zones differs.

Pricing analysis
The Real Cost of eSIM Data in Thailand
Pricing in Thailand tells a different story at each data tier. The cheapest provider at 1 GB is not always the cheapest at 10 GB.
1GB: $3.49 ($3.49/GB). 3GB: $4.99 ($1.66/GB). 5GB: $6.99 ($1.40/GB). 10GB: $9.97 ($1.00/GB). 20GB: $15.99 ($0.80/GB).
Best value: 20GB at $0.80/GB. Worst value: 1GB at $3.49/GB. Ratio: 4.4x difference between cheapest and most expensive per-GB rate. A 9-day trip at 1.8 GB/day needs ~17 GB. The 20GB tier at $15.99 covers that. Unlimited at $3.49/day = $31.41 total. The fixed 20GB saves $15.42 unless you exceed 20 GB. Pricing score leader for Thailand: Nomad at 4.8/5 on the rubric.
A local prepaid SIM in Thailand costs $5-15 for 10-30GB / 7-30 days. A SIM bought on arrival at Suvarnabhumi (BKK) / Don Mueang (DMK) costs $8-23 for unlimited data / 7-15 days. The cheapest eSIM plan in this matrix for Thailand is $3.49 for 1GB. The per-GB floor across the 8 scored Thailand plans is $0.29/GB.
