“... just can’t figure out how to get the SIM card out...”
If there’s not a slot for one that you can see, it may not have one. Some of those things were built so you have to connect them to a computer to download what you’ve recorded.
If you CAN see a card slot, and it has a card in it, but you can’t get a grip on the thing, try pushing the card IN until it stops, then release it. Many of these card slots have that clicky ball-point-pen action to them.
See? It just needed someone with a few more smarts than me!
Thanks! ;o]
