Answer to: "no SIM, or SIM error" when sending calls. Text and Data works."NO SIM, or SIM ERROR" is noted in red on my 2nd hand Sprint provider phone. Voicemail - Call or Message are the only choices that come up on the phone. I am Canadian who bought on Ebay a Samsung Galaxy S6 LTE and the home company is Sprint from United States. Everything else seems to be working right now but the when a call goes to the cell, it goes strictly to a voicemail that is not retrievable. The phone does not show as the Youtube video https://www.youtube.com/watch?v=b_7Gvl1X... The green screen on this video does not even come up on the phone.
