Nokia Betalabs has just released an app for Nokia Lumia devices to analyse and manage your phone bills by tracking your calls, SMS and data usages each month. It's exactly same function with "Counters" app for Nokia Asha 311 which have the option to reset your counter on your monthly billing date.
This app will show you the usage remaining before hit your bills limits.
Currently there is no notification when set limit is achieved and will come later.
Note: Counters app requires particular phone software. You can check firmware version in Settings>about>more information>"Firmware revision". It should contain string 8773 or 8779 (Windows OS version) as third number and it should start with 1750.xxxx for Lumia 800, 2175.xxxx for Lumia 900 and 1600.303x for Lumia 710 as example. Any smaller numbers means your phone SW has been updated partially (only OEM FW or OS FW has been updated) and rest should be updated in next slot. Most variant should get both OEM FW and MS OS during the same Zune update.
It's not available thru marketplace now but you can give it a try the beta version via Nokia BetaLabs http://betalabs.nokia.com/trials/counters
