As a designer

As a designer myself, I don't really like the look of it. It's not wonderful to have it on my hand as it doesn't look good. It can also be hard to use sometimes. I have a redesign of the app, would you like to have a look at it? (in fact I've tried to contacted you guys but unable to reach)

Does what it's suppose to

It's not the most beautiful or well designed app but it does what you need it for. To check your usage and balance (accuracy not confirmed). Far better than the non-mobile designed website anyway.

Useful but room for improvements

Should work over wifi and show monthly quota on top of what's used.
