This card is an unknown source

[milkysk]

Hi guys, as first, I am sorry if this thread is alrdy here.
I am in the US for the summer and I bought the LG G2 32GB Unlocked (link:ebay.xxx/itm/LG-G2-VS980-4G-LTE-32GB-Black-Verizon-UNLOCKED-Mint-Condition-/351119754968?pt=Cell_Phones&hash=item51c05e46d8 - instead of "xxx" place ".com")
I am from Europe - Slovakia and my operator is: Orange.
I tried to put different SIM cards from Europe and it always said: This card is an unknown source.
But when I roll the top panel, where you can see the messages,etc, I can see that the mobile recognized AT&T|Orange and the signal is showing the small "r" as "roaming", but I can´t get thru the image on the screen of the unknown source of card.
Should I just return the phone or is it possible to fix it?
And the seller told me that if I will do any changes by 3rd software or so, because i won´t get my money back ..
Any help?

You would need to flash a custom ROM to get rid of the message... The phone should work fine though even with the message. Most Verizon phones will show this with a non-Verizon SIM on the stock firmware.
