As far as I understand it:

* Opera Mini uses what is installed on the phone (I think it has its  
own generic serif/sans-serif too as a fall back but I'm not sure if  
that is still the case). I'd expect phone in India to be shipped with  
a font that can render the local language (or is that assumption too  
much to ask?). I'd expect Nokias (which are the most used phones in  
India for Opera Mini (and probably for any other major browser)) to at  
least have one. The Opera Mini UI is localised into many of the  
languages used in India, so I expect it has to work at some level. A  
US Android phone likely doesn't work as it will probably be using the  
Droid fonts. I'm guessing that doesn't include the correct glyphs (or  
at least the US version). StatCounter [1] suggests Andriod isn't  
particularly popular in India. At least for web surfing. Opera Mini  
has multiple millions of users in India (and across the Indian sub- 
continent) so that gives me further suspicion it works out of the box  
there.

* Opera Mobile (the smart phone browser) uses the Droid fonts rather  
than the fonts on the phone (at least by default). I can confirm that  
doesn't work with the site in question when using the Emulator at  
least (Its not really an emulator - it is exactly the same code as on  
the device, just a port to Win, Linux or Mac It is just easier to call  
it an emulator) [2]. I've looked atthe glyph table for Droid and it  
doesn't look like it supports any Devanagari glyphs. Even "Droid  
fallback" which includes quite a lot of extra glyphs, but mostly it  
seems for CJK languages. I guess if Opera Mobile is shipped in India  
it could be shipped with an appropriate font and it would work (as it  
does support Unicode TTF and OTF fonts (not not the none-standard EOT  
which we've had no end of problems with on Indian sites in the past as  
Shwetank alluded too (basically they'd use a EOT font to make standard  
western encoding characters (ABC etc) look like Devanagari glyphs,  
which of course rendered fine in IE, but looked like gibberish to  
other browsers, in view source and to screen readers.)

As mentioned later in this thread, CSS3 Web Fonts (not HTML5) can also  
be used, as you can link to one of the freely available fonts (which  
give you a licence to use Web Fonts). This works in Opera Mobile, but  
not Opera Mini (which is far bigger in India as it works on lower end  
devices). One reason for that is Web Fonts are quite expensive in  
terms of resources, bandwidth and storage requirements. Having to  
download hundreds of kilobytes (not to mention megabytes for many CJK  
Asian fonts) isn't very kind on the user when they are on a slow  
network and paying by the kb. Font subsetting can help of course. The  
WOFF format handles subsetting well I believe, but is not widely  
supported on mobile browsers, or even desktop browsers yet.
