    if you are still getting the No seicvre signal then your sim card might have not been cut and aligned properly. If you cut too much off your sim card and placed it in the GeVey sim tray and it didn’t work then you can 1) Try to cut a thin piece off from any spare sim edge and reattach it to sim to allow it to readjust to proper positioning for proper detection 2) Replace with new sim and try trimming again but with a thinner slice than before
