After using both the services, I feel more comfortable using the GSM Cellular service, Garuda is not that bad but they still need to improve on Network connectivity. Their service and support numbers are always busy and you will get totally annoying answers through them. But still Garuda is very easy on your pocket. One more advantage of Garuda is that it costs only Rs, 250 per month. I am thinking of surrendering my existing MTNL Landline by a garuda phone in my house, By this I will save on high rentals of the landline phone and I can use Garuda as a cordless phone too.
Thanks for going through all this, bye, for any queries on mobile phones and mobile phone technologies feel free to contact me on my email id. ( movin_max@hotmail.com )
