Don't get the wrong end of the stick like Bla!ze did; the new Bill Angel app from Carphone Warehouse doesn't mean that they will pay your bill for you. What it will allow you to do though is keep an eye on your monthly tariff allowance and get notifications if you are near your limit. Perfect for those of us that don't want to exceed our allocated quota.
The application is free to download and it is then just a case of entering your allowances for phone calls, sms and data. You then set your monthly billing date and you have the option for notifications to alert you at either 90%, 100% or both.
If you are a heavy mobile user and either don't want to exceed your limit, or cant afford too, the Bill Angel app is perfect.
And that's it. Simple, yet effective.
