Is Cellesim or Airalo cheaper for Southeast Asia?

Airalo often has lower starting prices for small data packages (e.g., 1GB for 7 days), making it seem cheaper upfront. However, Cellesim focuses on providing better value through premium network partners, which means more reliable speed and coverage. For longer trips or multi-country journeys where reliability is key, Cellesim's plans can be more cost-effective in the long run by preventing the need for top-ups or dealing with poor service.
