I noticed my data is mostly being used for chat. I do not use chatting apps. If someone has had access to my phone can they be using my line to hide communications with someone?
No one else can use your data unless you have a shared plan. No one has access to your phone.
Read the data usage in your phone, not on your myVerizon account.
If using iMessage for text, that would appear in ‘chat’.
Conflicting information can definitely be a concern, Stylingyou. Do not worry we are here to help address your data usage and chat app concerns. To best assist, I would like to gather some information. Where did you confirm this usage? What do you use data for on your device? Do you have Facebook Messenger or Snapchat installed on your phone?
