    I recently purchased a factory unlocked HTC One m7 on eBay. The phone shipped from the US and I live in Canada. I am currently using a prepaid Koodo sim card, and when I put it in the phone a message appeared onscreen saying "Sim card from an unknown source". How can I fix this?

    Hi and welcome to Android Central.

    You need to check your APN settings with that of your carrier settings. There is some information for you here. this sim card is from an unknown source Moto X CDMA Verizon It's a different phone, however, the principle is the same.

    Goodluck!
