As it is now the phone I bought doesn't work as it it not showing the netwrk . When i phone to it it doesn't receive the call. When downloading things like music yes it takes but since you've said it's a gig it onky take 200 songs. Thereafter it doesn't allow any movie's, games really its just a toy ohone. I even sent the email to ask for my refund will be the solution please
