it's not supported for the bios to run 3g and 4g it's a 1g and 2g network phone u can use the Wi-Fi but i mean the hardware isn't really compatible with a lot of the new tech I'm sorry I don't understand the question but there's a little info for u it would be hard to really use it now so many upgrades you're pretty much making a new phone but at least u can use the Wi-Fi is u use the right frequency's
