...talk does not work anyone pleas please don't link me to nokia or o2 as they are both of no use thanks
Opera is java based web browser that gives better features over wap based web browser. as this was installed on the new o2 branded nokia 6300 it should be usable (I have it working on old 6230 even with the same simcard so not the sim card at fault).push to talk is a walkie talkie type thing that works over gprs again it was preinstalled on the phone so it should work.

You might need to download, third party - software etc. ?

For the Push to Talk service ? Explain what exactly you mean, or want as in - Free Calls to same network or Free Int'l Call etc, ok

Someone here will give better info.

I've got no idea what 'opera' is but i know that if you've got a pay as you go phone, the push-to-talk function will NOT work. You must be on a contract for this to work and you must make sure your service provider will allow you to use the function.

Opera is preinstalled in the nokia 6300. Download opera mini 4 from here http://www.operamini.com/download when you have download it and install it delete the opera 3.
