HELP! i don't see that this got resolved and i am now having this issue. i've worked with Apple and Verizon and i get odd feedback like "we've never seen this before" but also "that's normal." these are contradictory statements! i need help. my situation is potentially wonkier than those described above, or others didn't review the spreadsheets of data usage. on June 1, 2020, ALL 4 lines on our family plan started having System Services use a lot of data 4 times a day. this literally was not happening through May 31, 2020. my sister and i live alone, my parents live together. we are all on wifi almost 100% of the time since we are all at home due to the pandemic. when i identified the increased data usage, i downloaded the data use spreadsheets from verizon. upon review, i found that the 4-times-per-day System Services data usage is the ONLY data our phones used. the information below shows the ONLY data used on those days. also note the trend of: 9:31 AM / 9:31 PM 3:32 AM / 3:32 PM DATE ----------TIME-------KB 08/03/2020 09:31 PM  588970.76 08/03/2020 03:32 PM  107499.42 08/03/2020 09:32 AM  3922.82 08/03/2020 03:32 AM  47.23 08/02/2020 09:32 PM  3006.04 08/02/2020 03:33 PM  20275.93 08/02/2020 09:33 AM  140517.67 08/02/2020 03:33 AM  186.57 08/01/2020 09:33 PM  258.62 08/01/2020 03:34 PM  2951.25 08/01/2020 09:34 AM  484.02 08/01/2020 05:56 AM  31.74 07/31/2020 11:56 PM  207766.12 07/31/2020 05:56 PM  183855.87 07/31/2020 11:57 AM  226.21 07/31/2020 05:57 AM  647.05 07/30/2020 11:57 PM  31.81 07/30/2020 05:57 PM  627.63 07/30/2020 11:58 AM  57769.69 07/30/2020 05:58 AM  57.92 i have done the assessments to reset statistics on all phones. we did not all download the same app or manually change the same setting, or all update to a new iOS at midnight on June 1st. at least 2 of us do not allow autoupdates of iOS. i recently got my dad a new phone. it continues to happen on his line. we do not have an unlimited data plan and we are running out of data each month.
