Make Sure you put correct event in your ox_inventory items.lua for phone like this.
['phone'] = {
label = 'Phone',
weight = 190,
stack = false,
consume = 0,
client = {
add = function(total)
if total > 0 then
pcall(function() return exports.npwd:setPhoneDisabled(false) end)
end
end,
remove = function(total)
if total < 1 then
pcall(function() return exports.npwd:setPhoneDisabled(true) end)
end
end
}
},
I use different phone and function.
