If you have doubt whether your Uninor SIM is 2G or 3G, you should understand the following fact.
Uninor (now Telenor) does not have 3G license in their 6 Circles. So they provide internet only through 2G /EDGE network which is very slow when compared to 3G. If you used to use Whatsapp, Facebook and Simple Browsing then Uninor may suits you.

Tata Docomo has 3G license in 18 circles. So, before activating 3G plans, ensure that your state or city has Docomo 3G signal. You can ensure 3G availability in your area by calling 198 (too free)
