My sister and I exchanged text messages at 7 p.m. Around 8 p.m., my husband sent a multimedia message to someone else. My phone and my sister's phone also received the message (picture was blank). Does anyone understand how this could happen? My sister's number is not even in my husband's contacts. Both are basic phones without internet access. My husband and my phone are on same family plan. Is he somehow receiving a log of my text messages? Verizon support did not have any answers.
