It depends a lot on your usage.

For a person primarily using:

  • WhatsApp / Messenger / Zalo
  • Google Maps
  • Grab
  • social media
  • web browsing
  • music

a standard mobile plan is usually sufficient.

A person using a lot:

  • YouTube
  • TikTok
  • Instagram
  • video calls
  • tethering
  • video streaming

will obviously need a much larger data allowance.

Vietnamese plans can be generous.

For example, the MobiFone international offer FR30 displayed in September 2026 includes 150 GB and 200 minutes of local calls for 250,000 VND over 30 days. This is a specific offer for international visitors and not a universal reference for local rates.

Offers change frequently: compare plans at the time of your setup.
