Counters app lets you manage your calls, messaging and data use each month. And there’s even the option to reset your counters on your monthly billing date.
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. Check for updates here.
