Ayutthaya eSIM plans: unlimited, or by the GB.
Every Ayutthaya eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Ayutthaya — you can always top up or switch on your next trip.
Unlimited plansHigh-speed data, nothing to count
Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.
- Best for streaming, video calls & hotspot
- Great for longer or open-ended trips
- One price per day — no GB anxiety
A set bundle, brilliant value
A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.
- Best value for lighter, shorter trips
- Clear allowance — pay only for what you need
- Top up any time from your phone
How much data do you need in Ayutthaya?
A rough, honest guide to sizing your Ayutthaya eSIM so you're not guessing. Most travellers in Ayutthaya are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Google Maps, WhatsApp, email and the odd search. Plenty for a city break where you mostly need directions.
Everything above plus social scrolling, music, cloud photo backups and a little video. Where most travellers land.
Netflix by the pool, long video calls home and hotspot for the laptop — go Unlimited and stop counting.
Ayutthaya eSIM: your local data guide.
Ayutthaya's UNESCO-listed ruins reward a full day of exploring - the Buddha head cradled in tree roots at Wat Mahathat, the Khmer-style prangs of Wat Chaiwatthanaram and the royal gardens of Bang Pa-In Palace. Cycling between temples, an Ayutthaya eSIM keeps maps, opening hours and your train back to Bangkok at your fingertips.
Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

Strong 4G across the temple island covers maps, history apps and ride-hailing between the ruins.

Getting around Ayutthaya on your eSIM.

Most visit on a single day trip from Bangkok, though an overnight stay lets you catch the ruins at sunrise and sunset without the crowds.
Light 1-2 GB is plenty for a day here - maps, history apps, photos and train bookings. Only heavier users streaming or hotspotting need to size up.
As a populated central town, Ayutthaya has consistent 4G/5G across the ruins and riverside temples, with only minor dips in the outlying rice-field districts beyond the historical park.
