Mae Sot Town: Grab / Bolt taxis available at what times?

Hello, about Mae Sot town specifically: are there Grab / Bolt taxis available? If yes,

- at all times from 6 a.m. to midnight?

- only in daylight hours?

- only motorcycle taxis, but not cars?

Thanks for your proven local insight!

I noticed in some northern towns like Nan, Lampang, Phrae, Phayao that sometimes

- there is no Grab / Bolt at all

- it's only available before nightfall and only motorcycles (food deliverers taking on a human)

- it's only available until about 10 p.m. - they take you to the pub, but you must stagger back

So it'd be nice to hear from somebody on the ground how much you can use Grab / Bolt in Mae Sot town or if there is another easy-to-use taxi service.

Thanks!
