Hello, I live in the united states and think the new phones (crystal and z1) look neat.  I need a new phone and I'm considering one of these phones but I'mm skepticak because I don't know the network bands and a lot of times these Asian companies don't us the united states frequencies.  If anyone knows the bands it would really help me out.

Thank you

So I cant start a thread unless I pay $$ ? The hell is that about ! Any way it clearly said LTE In on the Bell Network in Canada
Even though there is options to change to 4G ( it wont save !! ) it says 3G at the top of the screen !!

Press and hold for around 10-15 seconds power button. If still not working please charge for few hours and then try again with power button.
If still is not starting please contact seller.

Crystal 4/64 - Does anyone know if there is a celluar network module available this to convert to US raido bands. The default radio in this phone effectively only works on 2G.

If not I'll have to dump it on ebay. Too bad as it seems to be a really nice phone.
