Description

### Steps to reproduce

1. Start a chat with someone
2. Change SIM card
3. Continue chatting

### Outcome

#### What did you expect?

That the people I was chatting with can read my new messages.

#### What happened instead?

The person cannot read my messages unless I start a new chat.

(This error has happened to me a few times, changing SIM or eSIM, months ago. I'm not sure of my GrapheneOS version at that time, but it was the most updated one).
