We value your long time loyalty, and we don't want to see you leave Verizon! I know how important it is to be able to determine the source of your data usage, so you can more effectively manage your data in the future. While your usage seems to have not changed, changes in apps or app settings that you use frequently can impact your data without you realizing what has happened. We offer a Data Utilization tool on My Verizon that can help you identify the source of your data usage, so you can avoid unexpected data usage in the future. Check it out here, and let us know if you still have questions regarding your data usage.
