Hi I ordered one of these from dhgate and it doesn't work because my cellphone provider requires us to change the apn settings to get internet connection, so my question is will this phone allow me to change apn settings? And will it let delete or edit contacts? And on the one I got from dhgate will let me load the play store but when I try to install a app from it it will kick me out and say it is not working properly just want to make sure I don't get another dudd!! I really want to order from you guys....
