It is likely that many (maybe even most) SD cards of size 32 GB and less can be compatible with ChatterBox devices and firmware. However, if you deviate from the list below, you may have to re-partition and re-format the SD cards before ChatterBox can read/write via the cards, and there are certainly SD cards that are not compatible. The small voltage and speed variances can make a big difference. Please save yourself a lot of trouble and choose SD cards from this list.
The following SD cards are inexpensive and have been known to work. More are being tested and will be added shortly. If you try one of these and your device becomes hung on the Mounting/Decrypting step for more than 5-10 seconds, you may need to follow the partitioning/formatting instructions, or you may just want to try a different card. These cards are pretty cheap, and once you have one that works, you never need to take it out again.
