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) ### 3/5 — Does what it's suppose to *2013-01-06* 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. ### 4/5 — Useful but room for improvements *2011-12-27* Should work over wifi and show monthly quota on top of what's used. ## Frequently asked questions about 1O1O ### What can I do with 1O1O? 1O1O allows you to manage your mobile service plan, monitor data and voice usage, check your account balance, and access billing history.
