If you have a really, really big coin cell battery, sure.

GSM shields are not low power things.

then any other GSM module with low power ratings.
which i can run on batteries?

Thanx

Is weight an issue and how often and for how long are you going to be using the GSM modem? The high power consumption on these things is during transmit so sending one short SMS per day has a much different power consumption to handling several minutes of voice comms per hour.
