okay this is the scenario this time;
A rebel member was captured in order to intercept a message. There are several items he was carrying on him; his wallet, house key, an old mobile phone, and 5 piece of papers (as shown below). Figure out what is the message he was carrying.
There's something else needed to solve the puzzle, but what it is, is already hinted. You can also use an image editing software for help, although not really needed. The final answer will be in text form (words).
Sorry for a really long post, I need to use quite a number of images.
