Which e-sim would you recommend for use in Bangkok, Thailand?

My grandparents are heading to Thailand in late June for a short holiday. Instead of physical SIM cards, I was thinking of activating e-sims for them instead? To save the trouble of them having to carry around the small chips.

Any recommendations for e-sims with good coverage in Bangkok? I know of AIS, dtac and truemove but there have been varying reviews for each telco’s e-sim.

\- Good and fast coverage for 1 week
\- Easy activation (\*even better if I can activate the e-sim for them before they depart)
