I am looking to buy a new tablet with calling facility and as datawind announced it's four new tablets in the market recently, i want to know is ubislate 7C+ will be a right option to go against micromax Talk P350. If yes then please let me know as soon as possible.

What is your budget , now there are even better tablets in the market. For price of Rs. 7000-10000 or so you can buy a 3G calling tablet, you can look Spice Stellar Slatepad 3G. its better than both.
