Strictly speaking, any phone which can receive text messages can
receive Unicode messages. It's the ability to display them
correctly which will be lacking. GSM standards require that
received messsages be stored internally exactly as received.

Support for the display of any particular Unicode character set
is optional for phone manufacturers. People who wish to
receive and read Urdu language texts will need to buy phones
with that support built-in. The same goes for Tibetan, Latin
and Hebrew character sets, for example.

Unfortunately, only the 7-bit GSM default alphabet defined in
GSM 03.38 is guaranteed universal support.

From that u mean operating system of the old mobile phone are no
supportive enough to display that particular(urdu) kind of text???

Would u like to give me suggestion that making or designing some PD
format that can travel and can be viewable on any device (old and new
not depending on the operating system would solve that problem to som
extend??????

thanks for ur replies

Yes, the firmware in the phone will lack the required
sophistication. For most phones, calling the firmware an
"operating system" is a gross exaggeration.

The only way to guarantee that a message will be displayed
correctly on the maximum number of receiving devices is to
restrict yourself to the 7-bit default alphabet, and it's also
best to avoid using a UDH. A UDH (user data header) is
required by concatenated messages (those more than 160 7-bit
characters), and by EMS (enhanced messages containing graphics,
sounds, etc).

The 7-bit alphabet is the original European character set.
Unicode support came later, after GSM escaped from Europe
(beginning with Australia). And cheap phones (by their nature)
are not feature-rich anyway.
