omid badergan, 05 Jun 2013it means that you can call from both sims at the same timeOptional dual sim means it comes both with dual sim n also with single sim ie. Two variants 2 different models ...
Sony xperia M Dual looks great. I Expect same features with slightly Smaller in Size especially, similar to Sony Xperia Tipo dual in future Models.
Anonymous, 06 Jun 2013Lumia 520 is betterIt may be one of the best WP8 phones but WP8 is a dumb OS.Dont compare it to android which is a fullfledged OS.
Over-all good specification but could be better if there would be
1. 8 GB ROM in place of 4 GB
2. 2000 mah Battery against 1750 mah
3. Design would be different
[deleted post]Bro in my city S duos price 11k.........and very soon it will be 10k :) Because more choices r there :) Most peoples buying mircomax a116, lg l5ii dual @ same price But in 10k budget Nokia lumia 520 on top.

Abdul, 06 Jun 2013All is good but memory only 4gb not enough for me. In 4gb may be 2gb for users. Nokia lumia 52... moreApplications or games can be istalled in memory card in sony xperia phones but not in samsung phones.
Anonymous, 06 Jun 2013hy ..sony..why cant u change the design of the phone ...all are look like same....make diffarance..you cant see diffrence in design ? I think you need o eye checkup
All is good but memory only 4gb not enough for me. In 4gb may be 2gb for users. Nokia lumia 520 have 8gb internal memory in which 6gb for users and newly samsung win with 8gb internal memory in which 5gb available for user. If application installing in micro sd card no problem other wise no chance for sony.
