    All Verizon LTE phones are factory unlocked to use with other carriers. I have two Verizon LG G2 phones (model VS980) one is on active service with VZW, the other is off service that I just bought on eBay. When using a foreign SIM, in this case a Singapore Simtel SIM, my active phone detects the SIM no problem, shows the Simtel phone nbr etc and the local partner network which is T-Mobile. The other phone however, using the same Simtel SIM gives me an error message: "This SIM card is from an unknown source" and I am unable to proceed with setup and can't even get into settings. Both phones are identical except one is on active service. Has anyone figured how to get around this problem? Thanks in advance.

    Have you used a Verizon sim in the phone before to activate the device?

    Also not all Verizon 4GLTE smartphones are factory sim unlocked. A number are, but not all.

    No I have not used a Verizon SIM on the eBay bought phone. I was thinking of sending it overseas for use there and don't want to activate it on Verizon.

    Why not activate it on Verizon? It can still be used on gsm networks after activation

    I have the same problem, my Verizon Note 3 was bought from China and I never have a Verizon SIM card, is there a way to get rid of the "Unknown Source" notification? Thanks!

    I'm in Kenya, bought the Verizon M8 on ebay. The phone works fine but I also need to remove the Non-Verizon SIM crap!
    I've rooted and installed viperone M8 1.6. I tend to believe its just a small tweak needed.

    Probably best to ask in the HTC One (M8) forum then, not in the LG G2 forum, or in the specific ROM thread on XDA (or wherever it is hosted).

    On a side note, the ROM you using is still stock Sense-based, so you might not be able to remove it without switching to an AOSP or CM based ROM, but I would ask in this forum: [ROM][MAY 11] ViperOneM8 1.6.0 | 1.54.401.5 | Android 4.4.2 Sense 6.0 | Immersive Mode, Venom Tweaks, Venom Navbar, Venom Sidebar, VenomPie, Venom Hub, Theming, Icon Packs, OTA Updates and more! - Support for all Variants - xda-developers

    Go to settings/more setting/mobile network/switch it to global/go to app manager/all apps/force stop setup wizard/repeat if notification persists

    You need to make sure the APN Settings for which ever provider sim card you put in their are correct!

    I placed a T-MOBILE Sim Card in mine, and the APN didn't automatically update, but the ATT Sim Card did! I had Perfect 4G LTE... The Issue is that Some times the SIM Card from the other carrier doesn't Automatically bring down the APN (Internet and MMS Settings) to be able to make the phone work correctly

    Most Verizon devices require you be on Verizon's network to OTA update... Try Kies or flash image via Odin?

    Use the Samsung update utility when plugging it into the computer. It probably can't get OTA when not on Verizon network

    Samsung?? Lol... Don't think that will help much here, pretty sure you meant LG... Yes, use the Verizon Software Update tool or LG's tool.

    You don't on the stock ROM, it is not service affecting. There may be an Xposed mod, but the only way to really get rid if it is flash a custom ROM, this will also eliminate any MMS issues.

    I got to settings and to app manager, and found three setup wizards. force stopped all of them, but when i go back it brings me back to the same sim card screen. went back to app manager and found that one setup wizard started working again, force stopped it but the problems persists. Should I try to clear data or clear cache?

    Yes... And no... It means you cannot update to Lollipop (or other updates) via OTA update process. You can always use Verizon Update software (although some users claim to need VZW Online Acct credentials), or wait for a KDZ or TOT file release and flash manually.
