Hello,

I changed operator and this new one only works with 3g 900mhz and 1900mhz band, is there a way to fix this problem? actually i installed the 4.2.1 jb on the zoppo web page and didn't work..

Thanks.

Hello Joan, long time no see.

The only way to fix the problem is to buy a new mobile. The H7500+ is 850/2100.

, thanks for the info!.
