Networks. Local partner networks (Airalo plans: Sri Lanka data-only and Ella+ with calls/SMS). Hotspot and fair-use rules differ by plan, so check the plan details on the provider's site before you buy.

Rarely. Most unlimited plans slow you down after a daily fair-use cap and may limit hotspot use. Check the cap before you buy.
