Iphone 5C , Kiddi Japan unable to activate
 

I have a japan locked iPhone 5C 32gb, locked to Kiddi. I put in the rsim and my philippines sim card, the menu comes up and i select Japan AU, and 2g/3g (the first choice) I restart the phones and it seems to have a signal/bars . When i go through the setup at the end it says "your iPhone could not be activated because the activation server cannot be reached"

How can i fix that? I can't get past that screen , This phone has an iCloud issue but i used the iCloud bypass. I just want a working phone for calls and texts

Previously the owner of this phone had it working with his sim
