How to reach Hotels.com from a mobile within Thailand?

[hermespan]

Their website gives a toll-free number - but that is inaccessible by my DTAC mobile.

They also provide a +65 long distance number (Malaysia?)

Makes doing business troublesome when their website is down. Sometimes making a reservation isn't a simple matter - one person arriving early, half-days , flexible checkout dates, whatever.

I narrowed my choices down to three and am now inspecting prior to my boss's arrival. Surprised that Hotels.com is substantially cheaper than walk- in, even though there is no middle-man. The opposite of when I booked through state-run travel agency in Hong Kong on my first trip to. China. In that case I would have SAVED 50% at the Shenzen hotel just by walking in.
