If i get shared data 2gb on iphone?

When the limit is over can i still use the apps and surf on safari? Or will that just mean i can't download more apps. Also when i get over the limit can i just delete apps and ill have space?

When you go over the data limit you will be charged a fee, but everything still will work, including surfing, apps, downloading, streaming, etc

what you will be charged varies from service to service, but Verizon for example charges $10 for every gb over the plan allowed.

You can't delete apps to get more space. If you go over your data your going to pay more.

Contract carriers will certainly let you continue to use data even once you've reached your two gigabyte limit. They're just going to charge you a lot to do so. On older plans it is typical to be charged $10 per gigabyte you go over. On the newer share everything plans and plans where one data package is shared between multiple phones the overage charge is more like $15 per gigabyte.

Deleting apps will give you more space on the phone to store things, but the phone memory is not the same as the Gigabytes allotted for data usage. The only way to stop data usage if you're close to going over would be to put the phone on Wi-Fi if you have it available.
