I contacted the seller for more info.
Otherwise it is the best flip phone I've tried: light, strong, very fast, very good battery life (rare).
Photo correct for MMS.
It's a good phone utility, fast, simple, for calls (good ergonomics) and messaging. Point.
Cons: lack of 3G (for MMS and the occasional speed internet) and the keyboard is a little soft (he held at the time?)
Goodies: jack 3.5 standard (music ...), micro SD slot, no external buttons (no risk of accidentally activating a function) and the possibility
take a call and cut either by opening the valve or manually with the keyboard (useful for filtering because there is no outdoor nag screen).
Nothing to configure home (free) for MMS and Internet, it works on (and this is not always the case, sometimes it is a nightmare!)
If it had 3G, it would border the perfect for this kind of phone (which of course has nothing to do with a smartphone)
So 4 stars because it lacks 3G (against it by a star to see zero confusion over 3G)
Edit: after search:
C3590: no 3G
C3595: 3G
C3592: Dual SIM
This remains to be confirmed, as this is confusing is seems to vary from one country to another.
So if you want 3G is the 3595, and it is more expensive (still have to find a French firmware!)
