with verizon we can see detailed usage. as far as texting goes we can see the number from incoming msg and number to whom we sent a txt to. With a blackberry, and using bbm does that too show the phone numbers on the bill?
I believe the answer is no. I don't use BBM very often but have never seen it on my usage details.
No BBM details are on your bill, because it counts as data usage. And no phone numbers are involved, just BB PINs. So all you can see for details is how many KB you used on a certain day, and that's for all data, not just BBM. Hope that helps.
