I know some of us have been asking for a prepaid app that shows voice and/or data usage, but my ask/suggestion is a little bit different, and something that could be implemented much quicker and cheaper. Provide the ability for a daily SMS text or email showing amounts used and remaining balance. This could be user selectable via the online self service site. Give us the option of which one (data or voice or both) to receive, frequency (daily, weekly or monthly) and method (SMS or email). If an SMS option was provided, give us the ability to select a time - for example 7am daily so you know how much before starting the day. The beauty here is that it's a) quick and easy to setup, b) will support any phone or user and c) is much cheaper to implement and support that a dedicated "app" It would also be great to be able to request this info on demand - for example send a text to number xxxxxxx and it replies back with the info.
