Load balancing is when you change a customers primary network from orange to blue. Network integration is a process that as I have previously said is gonna take some time. But it you have a customer that lives in a low signal area for orange and a high signal area for blue. And you look at card and their PLMN is orange do a case in clarify to move them to blue PLMN. the downside of this is it is not reversible and if a customer goes to high signal area for orange phone will stay blue first. This should only be done as a last resort when everything has been tried. Or if the singalarea is so low that you think nothing else will work.
