ZZKEY question

I want to buy a zzkey dongle but I want to know, can I use with one unique module to get all brand unlock if is supported by zzkey? or I need to buy each dongle for anything brand?.

for example: with one unique zzkey dongle can unlock all phone supported or I need to buy...huawei-huawei zzkey,nokia-nokia zzkey....?

thanks
