    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.
    Go to settings>more settings>mobile networks> network mode>then select global or gsm because cdma is what's not letting it go away, but there will be an annoying notification but you'll have to deal with it

    It is likely either a bad connection (remove and reinsert the SIM), a bad SIM, or a defective device... If removing and reinserting the SIM followed by a reboot doesn't clear it up, stop by the local VZW corporate store for a replacement SIM, if you have to call support to get a replacement be prepared to factory default the device, they will often make you try it before sending out a new SIM. If all those things fail, it is likely a bad phone.

    If this is NOT a Verizon SIM, then your "Unknown SIM" message is normal... and it is not related to your SMS issue (MMS possibly, but not SMS).

    Yours is more easy, simply hold your finger in the notification till it apear a small menu option, open it en select close app, o something like that, and you will get rid of it, but still every time you reboot your phone it will appear again. I tried to do the same thing in my LG G2 but it does not apear the notification icon
