Keeping track of mobile phone minute usage

One of the things that I can’t stand about being a mobile telephone subscriber is the worry about overage charges. A long time ago, I did go over my monthly allocation, and paid for it at 35 cents per minute. (Years ago, the company I was working for at the time refused to pay for the overage at first, even though it was incurred working a major customer problem, but they did come around eventually and cut me a check.)

Well, Winston Huang felt my frustration, and has released a Firefox plug-in that checks my T-Mobile minute balance. Now, every time I open a web browser, the minute usage is displayed in the bottom bar. Here’s what it looks like this morning:

The only thing that needs to happen now is a monthly graph so you can display trends over time, for visual people like me. It would be nice if I could see how much data I’m using, too. Although my T-Mobile data plan is unlimited, there may come a time when they charge by the bit, in which case, I’ll want to track that, too.

(If you don’t subscribe to T-Mobile, Winston has a Verizon plug-in, and his site has links to a Cingular plug-in, too.)
