Since switching from my iPhone to my brand new LG V10, I've had numerous issues with people still texting me via iMessage. It's been a major headache and, sometimes texts go through as a SMS and other-times they still go in as a iMessage (and of course I do not receive them). The worst case is that my work partner cannot text nor does he receive my texts even though I deregistered my number and, told him to try texting me again without replying to our existing chat. I've supposedly deregistered my number from iMessage (typing in my number on their website) but, it's still a problem with at least 3 iPhones. Do you guys have any suggestions I could use to fix this?
