I bought the Nokia 101 in Phantom Grey colour using a Sulekha deal. I am using it in dual SIM mode for last 4 months. For the price, it is a good value for money phone. You can copy your songs on MicroSD card and use it in the phone. No USB, Bluetooth to sync is a downside.
The build quality is not very scratch resistant. Battery life is about 12 days using dual SIM mode all the time.
If you need a dual SIM and want a not-too-expensive workhorse, this is the phone to have.
