This project is now abandoned, in favour of "big keyboards for PopOnTop".

No more releases of Bigkeys will be released.
Here you can find latest (unstable) versions, besides the official 1.83b: ,
I was trying to let BigKeys support big fonts, but I gave up due to too many difficulties and too few time...

Here you can find the all OPL sources from 1.8.3 to, just in case anybody would
like to carry on the project for further development.

PopOnTop currently appears to be "abandonware", i.e. none is anymore supporting it; anyway, the shareware version has no limitations, just install it without registering, and it will work forever. Sometimes it locks up:  keyboard appears, but no character is written. Solution: just restart the phone.

for Motorola a1000
By Luca Cassioli 2005

Bored of mini-micro-little keys for writing SMS on your a1000?
Are your friends able to write SMS using one hand and their 50$ phone, while you need two hands and a pen with your a1000???


Use your THUMBS to write your messages!

Customize the keyboard using any image you like! Just setup a 208x275image and put it into a standard MBM file using MBMWIZARD (click here to download MBMWhizard from, save it as bigkeys.mbm into documemts\BigKeys folder, and you've done! (DON'T USE XNVIEW to create MBM files: it would CRASH the program!)

Program requires OPL UIQ Runtime installation; it is included in SIS package since v. 1.7.4, but you can download it separately too:

Once installed the program, copy any 208x275 .MBM file into program folder (c:\documents\bigkeys) to use it as keyboard, then configure properly c:\documents\bigkeys\bigkeys.ini to match your keyboard and phone model. Then rename file to BIGKEYS.MBM

Please install MTMDetector on your phone, run it and tell me (cassioliATiolDOTit): I'll see if I can make BigKeys compatible with your phone.
