Hi,
I have a 1gb data package on my iPhone 5 and am a heavy user and only get close to the limit.
I have only had to buy a bolt on once !
Try to switch to wifi where you can and turn off 3g and mobile data as the iphone flicks from wifi to 3g when the screen goes into sleep mode to save data.
Heres a handy link I used.

Download 'Onavo Count' from the app store as this will help show you whats being used.
My02 will help too.
Go into settings,privacy, location services and toggle off what you dont location services on for.
These are tips ive picked up from other communities and kept them to pass on.
iCloud Backup: Turn it Off except when you need to do a Backup to iCloud…
Otherwise iPhone will automatically do a Backup over WiFi and/or Cellular Network, while it is on Power, and sleeping.
Settings, iCloud, Storage and Backup, iCloud Backup, Off.
System Services: apparently, some of these can be demanding on Cellular Network usage...
Settings, Privacy, Location Services, and scroll down past the notes at the bottom of the list of Applications, and select System Services, and turn them all Off except Cell Network Search.
If the Maps Traffic service is important to you, turn it On, but be warned it may be a bit of a hog.
Siri: every iPhone User now understand how to use Siri…
However you should be aware that Siri support has been expanded significantly in iOS 6, to include operation of your iPhone, to send text, make appointments, find restaurants, make bookings, and handle your dictation. The catch is that Siri services contacts the Apple Server via the network to translate your voice, do the searches, and return your results. You can leave Siri On but be aware of using Siri, when you are only connected via Cellular Data, and low on Data Usage remaining…
Settings, General, Siri, Siri, On. by default,...
Mail: you can set up mail to better manage Cellular Data Usage, if it suits your operation…
Settings, Mail, Contacts, Calendars, Fetch New Data, Push, Off, and set Fetch to Manually.
And select, Advanced, and for each Mail Account, Select Schedule, Manually.
Advertising: Settings, General, About, scroll down to Advertising, Limit Ad Tracking, On.
Diagnostics and Usage: Settings, General, About, scroll down to Diagnostics & Usage, Don't Send, On.
