How to open a Flex 6300 to install a new SIM card

Gregg E. McArthur

Do I need to get a special mini-torx tool to take the cover off? What other things do I need to dis-assemple?

Hi Gregg,

Here is a link to the directions for installing an ATU. This should be enough to get the lid off and the ATU out. Note that it is a high-endurance SD card, not a SIM card. You will need an SD card supplied by Flex (and tied to your radio), not a generic card that you get somewhere else.

Of course, as soon as I post, I find better info… Here is a link on replacing the SD card in a 6300.
