Similar issue to this post: https://community.virginmedia.com/t5/Virgin-Mobile/New-sim-requesting-Network-lock-control-key/m-p/4...
The Samsung device has always been on VM.
I tried this page, and have waited a WEEK and nothing has come via email: https://www.virginmedia.com/help/unlock-code-request1
I've been on listening to hold music on customer support for near 20 minutes now.
Please advise, thanks!
Problem solved, phone is 3g, sim is 4g!
