BUT DOUBLE-FUNCTION SIM is nice, the surprising Radio, and when it is covered with its black hull does not give the impression of having to break shortly.
And since (it's true) can not write about Sim Free Map ... well contacts are recorded globally -including IN TELEPHONE I somehow boosted memory. And besides, I'd rather have all my solo in GSM.
We can decide to disable one of the two Sims -It is seen quickly because the Network Name disappears and the bars Zero-fall to save a bit of energy.
Sensitivity looks good, compared to other, and the quality of modulation as well.
Then of course there is not worth the SONY Xperia ARC (I too ...) (laughs)
but it is still working properly.
THAT PRICE-LA = I recommend without reservation!
