Testimonials

"I haven't paid a dime of overage charges since I started using CellKnight. This service has saved me literally hundreds of dollars per year ... and it's free. It's a no brainer, I'm a CellKnight fan. Thank you!"    - Fred Jabbour

Heck, testimonials aren't needed. There is no other practical way to track your usage and be warned about impending overages. It works, period.  - Mike Grenier

Considering how unobtrusive CellKnight is, its utility is simply astounding. I signed up once, never logged back in, and get my weekly alerts. It's so easy and useful, and I've never got an unexpected bill from my cell provider. Huge thumbs up! - Johnny Lee

"Since subscribing to CellKnight I have never incurred overage charges, and CellKnight has saved my bacon, twice!
My family is on a tight budget and we share only 600 T-Mobile minutes per month.
In March it was reassuring to receive my 500-minute Yellow Alert came on March-26, and the 530-minute Orange Alert on March-30. I finished the month using 550 minutes.
The previous month was the bacon-saver. On February-25 I received my 580-minute Red Alert. I finished that month using up 600 out of 600 minutes. Not a minute more!
I cannot live without CellKnight.
- Stephen, civil engineer & father of four
