I bought this mobile 3 months back for the purpose of using dual sim. The following points may be notable.
Lots of spelling errors in the menus
If I select 10 messages randomly(not in sequence) and delete them, it deletes first 10 messages. which is very bad.
Contact syncing is not easy to go with.
You will miss all the calls in sim2 if you are talking with sim1 and vice-versa
Charging stands for 3 days. that is the only good thing to see with it.
I would say, If you are looking for dual sim mobile, then go for Samsung. Compared to Videocon Samsung duals sim mobile is good and compact.
