My boyfriend is the primary account holder and he's threatened to go online and read all my text messages. Is this possible? He doesn't have my account name/password. I've read through a few of the other boards and so far everyone seems to say that you can only see the numbers to and from but not the messages.
The only way he can read your text messages is on your phone, or with a court order to pull the info from wherever the data is stored. There is no way online to see the actual content of the messages, just the numbers to and from.
