Samsung S7562 Still unclear about dual sim functionality...Experts Pls advice?
I have purchased Samsung Duos S7562 based on so many general positive good.
However I am still confused about dual sim actually functioning properly.
Could somebody who owns and have used it with an insight offer explanation for me Pls.
1. Which mode to select for each sim - GSM only, WCDMA only, or auto? why?
2. Which data network to select sim 1 or sim 2? why?
3. Whether to tick receive incoming calls from other sim option? what are its impact? slow network / cost etc?
4. Dual SIM mode ? how to use it? any downside?
Pls explain with examples.
Thank u so much and looking forward to ur replies.
