I was considering going to a lower priced plan so I was looking over my text message usage to see if I can drop down a tier.
I noticed that the same number being text/picture messaged is sometimes shown as "domestic text" and other times "M2M". This IS a Verizon number and its not just happening to one, but to multiple Verizon numbers I text.
I don't know if this is just a coincidence but when its shown as M2M it tends to be in the evening, and when its shown as domestic it tends to be in the day.
Does whether or not it gets charged as one thing or the other depend on the time of day of the usage?
