Recent SD cards are too expensive to use, I think that it is more convenient to replace several pieces cheaply with a small capacity, since you can take pictures as they are, there is not a cheap card of a small capacity from 16 MB About 36 MB of SD or micro SD card.
I purchased it for use on the Panasonic FAX phone "Ocean Junior", but I could not use it because I got an indication outside the standard. I could use it for the Panasonic digital camera. Another SD card can be used with "Ocean Junior". Although I called on Panasonic and Transcend to explain the circumstances, from the above circumstances it is not a defect of the telephone and the SD card but a so-called compatibility problem so that it can not be solved. I am using it for my digital camera. Also, I should purchase Micro SD instead of SD card and use SD conversion adapter. Because micro-SD also works well for mobile phones and so on.
