## How to Choose

Ask yourself:

1. How much data do you need?
- Light (messaging, maps, email): 3-5GB/month → Airalo or Saily
- Medium (video calls, social media): 10-15GB/month → Nomad
- Heavy (streaming, tethering, business): Unlimited → Holafly

2. Where in Thailand are you going?
- Bangkok/Chiang Mai/Phuket only: Any provider works
- Islands (Koh Samui, Koh Phangan, Koh Tao): Airalo or Saily (AIS network)
- Rural/northern Thailand: Airalo or Saily (AIS network)

3. Do you need a Thai phone number?
- Most eSIMs are data-only
- For Grab, food delivery, or local calls: buy a physical AIS tourist SIM at the airport (~$10-15 with data + calls)
- Run both simultaneously: physical SIM + eSIM

## Thailand eSIM FAQ

Does eSIM work everywhere in Thailand?
AIS (used by Airalo and Saily) has the best nationwide coverage. True Move H (used by Holafly) is strong in cities and tourist areas but weaker on islands and in rural regions.

### Can I use eSIM and my home SIM at the same time?
Yes. Most modern phones support dual SIM (one physical + one eSIM). Keep your home number active for calls/texts while using the eSIM for data.

### Do I need a Thai phone number for Grab?
Yes, Grab requires a phone number for verification. Options: buy a tourist SIM at the airport, or register with your home number (SMS verification works internationally for most countries).

### Is buying a SIM at the airport better than eSIM?
Airport SIMs (AIS/True/DTAC tourist SIMs) are cheap (~$10-20 with generous data) and include a Thai phone number. But eSIM is more convenient — no store visit, instant activation, no SIM swap. If you need a phone number, get both.

### Will my phone support eSIM?
iPhone XS and newer, Google Pixel 3 and newer, Samsung S20 and newer, and most 2023+ Android flagships support eSIM. Check your phone's settings under "SIM" or "Network" — if you see "Add eSIM" or "Download SIM", you're good.

### How fast is mobile data in Thailand?
4G/LTE speeds typically range 20-50 Mbps download in Bangkok and major cities. 5G is available in Bangkok, Chiang Mai, and Phuket. On islands and in rural areas, expect 5-20 Mbps.
