Bold or other formatting may not show up if tor-talk server only sends
plain text copies of messages to subscribers; or if subscribers choose
to get plain text messages.

Thunderbird & Mozilla apps interpret special characters to add simple
formatting in plain text messages.  *bold*, _underline_, /italics/. I
don't know if non-Mozilla apps recognize these tags. They may not see
any formatting.

AFAIK, regardless of internet connection, your personal mobile provider
knows much of your phone's device ID data, your geo location (if GPS
"geo-location" is enabled in settings), who you call / text (or who
calls you), probably content of texts (at least scan / log them) - like
most email providers do.  Three letter agency(ies) could also get a lot
of the same data.

You gave the provider all that identifying data anyway - or they get it
- when their sim card is in your phone, if it's turned on.  If emailing,
the only way to avoid snooping - by someone or agency or nation state,
is if both parties using strong, end to end encryption.  Starting &
ending on each party's device - if they haven't been infected.
