There are 3 providers in Thailand. They all have similar coverage - sending text abroad and receiving is much cheaper on a Thai SIM or e-SIM. If you buy an e-SIM off another company, they will still be using AIS, Dtac or True as carrier.
some phones are not compatible with e-SIM so just exchange your home SIM for a Thai one.
Some phones have twin SIMs in which case you can keep your home SIM in place and use the Thai SIM a default.
I don't know of anyone who has come to Thailand that hasn't been glad to have a data package on their SIM. AIS provides very fast (110 -240 mbps) data in a variety of packages which will also have oie call and text allowances.
To get the right package, don't buy at the airport or at a
****
- go to the provider shops which you will find in most shopping malls/centres.
this is the address for the AIS site - it's very big! -
