TLDR : Answer Summary

The best SIM cards for a one-month stay in Thailand include options like AIS and Dtac, which are recommended for their coverage and ease of use. It is possible to reuse a SIM card by recharging it; maintaining activity with a small monthly top-up is recommended. E-SIM options also exist that can be cost-effective, providing data without the need for a traditional phone number.

Buy an esim off traveloka/klook/trip.com for a fraction of the cost. I get an esim for 2 dollars with 10gb for a month each time I’m

There. Obviously no phone number and only data but that’s enough for me. Never got sim cards for years while traveling ..

I would go with AIS. Best network.

But I guess you stay in tourist zones, so signal strength isn’t a thing.

Go shopping for promotions at the arrival hall. All major companies have a large booth there.

Just get a non tourist SIM..download the app and top up 10 Baht a month to keep it active. 6 months at 10bht a month up up keeps it active.

you don't have to top up every month. You can explicit extend the validity before leaving Thailand up to 1 year in the app or dialing an ussd code. It's only few baht for 30 days
