Quick answer
Most travelers in Thailand use about 1 to 2 GB per day for maps, Grab, messaging, and social media. That makes the 7-day 15 GB plan enough for a typical week. If you stream video, make many video calls, or work from a laptop, choose an Unlimited + Calls plan.
How much data do common apps use?
These are rough figures. Real use depends on video quality, auto-play, and app settings.
- Maps and Grab: small. A day of navigation and ride booking is usually well under 200 MB.
- WhatsApp, LINE, and Messenger text: very small. Photos and voice notes add more.
- Instagram, TikTok, and Facebook: heavy, because video plays automatically. An hour can use several hundred MB to over 1 GB.
- Video calls: often 0.5 to 1.5 GB per hour.
- Streaming video: from about 1 GB per hour, and more in HD.
