I haven't gotten the usual messages on my DIAD lately.............you know the ones that ask if you had any late air, or if you have a call tag, or when you will be back at the building. I asked about this and was told that UPS is charged 25 cents for every message sent and received. This makes me think that cell phone usage will be up. I personally do not use my cell phone for work, but i know a lot of drivers do. What i want to know is who is collecting the 25 cents, and is UPS just banking on us to use cell phones.
