I use mts mblaze and at this time also using mts mablzae. its very good and fantastic speed like 3Gplus some time I did face some problem but it was a little bit. I have used airtel and idea internet and also docomo 3G but I did not get complete satisfaction from theses services.
I know that MTS plan become some costly but I like speed of this so I will suggest that if you can spent approx. 1000 rs. on your internet hobbies then you should use MTS Mblaze.
