This is the canonical, monthly-reviewed reference for eSIM hotspot and tethering policy in Southeast Asia, based on providers' binding Terms of Service rather than marketing copy (verified 28 May 2026, next review 28 June 2026). Tier 1, no provider-side cap: Roamless ('no speed limits or data cap limits on how much you can hotspot', PAYG) and Ubigi (no Ubigi cap; requires a one-time mbb APN change). Tier 2, usable throttle: Maya Mobile (3GB/day full speed, then a still-usable 10Mbps, then 1Mbps; AUP allows Zoom but bans router use) and Airalo (3GB/day then a clean 1Mbps; 'no limit on tethering or number of devices'). Tier 3, tight throttle: Saily (5GB/day then 1Mbps, ToS warns on 'excessive tethering') and Nomad (only 2GB/day then 512kbps, the tightest in the set, too slow for video). Tier 4, avoid for laptop work: Holafly destination plans cap hotspot at 500MB-1GB/day (its own pages conflict); only the separate $64.90/month Holafly Connect offers unlimited hotspot. Tier 5: Jetpac markets 'unlimited' but its binding T&C never mention tethering. For sustained laptop sessions, USB tethering beats a WiFi hotspot. Verified May 2026.
