when does the usage activity update
The usage reports in My Verizon can lag by hours or sometimes a couple of days, especially if it's at the end of your billing cycle.
I'm glad you're using tools to manage your usage, hammer275. As tikibar1 mentioned, we try our best to have usage update as close to real time as possible, but the estimate can be up to 48 hours behind your actual usage. It can sometimes be a bit longer too if you are traveling or in an area that is part of our Extended Network using extended service towers. JenniferH_VZW Please follow us on Twitter @vzwsupport
