Since the Sunrocket demise in July, we have been living with just a cell phone – no landline or VoIP – and it’s actually worked out pretty well. I like the simplicity. We haven’t had any overage problems, but I did tend to check a lot in the beginning to make sure. Here are some easy ways to to check your remaining minutes for several cell phone providers:
Dial *MIN# (*646#)
AT&T Firefox plugin (might currently be broken)
Dial #MIN (#646)
Verizon Firefox plugin
Dial #MIN# (#646#) or dial 611 + say “minutes”
T-Mobile Firefox plugin
Dial *4 or dial *2 + say “minutes used”
Sprint Firefox plugin (not currently working for me)
Then there is the Windows desktop application WatchMyCell, which logs into your online account page for you and tracks how many minutes you have left. It will even send you an text message or e-mail whenever you’ve reached your chosen threshold.
Now, all of these automatic methods will require your username and password. Although I’ve done some digging and found nothing obvious, I can’t be sure none of them are doing anything shady. I would at least change your password to something unique to the site. Personally, I just program the number as a contact. Let me know if I missed anything.
