Yes and No. It is designed for fixed point Internet, rather than mobile usage. For mobile usage there will be many ‘dead spots’ where there is no signal. There is a process to determine whether it will be available at your home location. If you go via that process, you’ll have seven days to test the product. If it doesn’t suit within the test period, they’ll refund your money. Your phone would need to support Band 40.
If you want an unlimited data SIM for mobile usage, the cheapest is NT Mobile Unlimited 10Mbps over 12 months for 1450 or MybyNT’s Unlimited 10 or 30Mbps for 1350 & 1890 baht respectively.
You can subscribe for just one month to test any of them.
