Hi @dianecushing
Can you still make/receive calls and messages OK using the phone?
If you can't perhaps the SIM card may have become dislodged from the SIM tray and preventing it form being removed.
Just verifying that you're trying to eject the tray as is shown in this [https://www.youtube.com/watch?v=Dig3A63t8RM|video], is this correct?
