The Chess.com mobile app works well on a broad range of mobile phones (provided they support Java and can connect to the Internet), but some models are problematic, and some users get errors using the normal link to download and install the app.
If you're having trouble, here are a few things to try:
1. Try this alternative link from your phone's browser:
http://chess.com/mobile/bin/www.chess.com/Chess.com.jad
That alone solves the problem for many users.
However, if that doesn't work and you are still getting errors, you may have better luck installing the application via computer:
2. On your computer's browser, open this link: http://chess.com/mobile/bin/www.chess.com/Chess.com.jar
3. Download the file and save it on your computer
4. Transmit file "chess.com.jar" to your mobile phone from the computer - using a cable, bluetooth, card-reader, etc.
5. Install on your phone
We hope that solves the problem. If not, please contact us, and we'll do our best to help. Unfortunately, it may simply be that the app won't work on your model of mobile phone.
How can I send this application to my mobile?
I wrote my telephone number several times but it says: "authentication failure".
For example, if I have +10 & my number is 12345678, how is right to type?
