Phone is saying sim network sim blocked enteri network Puk which I have tried and to no avail tried nuc Treadwell on the off chance still nothing. Is there a master code I see people mentioning I need for this
Ignore the request for a Puk @Pjrankin87 as this has nothing to do with unlocking a phone to all network's.
Samsung phones sometimes need an unfreeze code aka a mastercode which customer service on 191 or Live Chat can help you with.
