one of my favorite contacts is set to to the private SIM card, imessage also uses the private SIM card and when I open an existing conversation I can only send normal messages but no iMessages.
tabbing the ”i” in the Message app shows, that “business is used for this conversation“.
How do i switch to private for this conversation?
Let your iPhone remember which number to use
When you call one of your contacts, you don't need to choose which number to use every time. By default, your iPhone uses the same number that you used the last time you called that contact. If you haven't called that contact, your iPhone uses your default number. If you want to, you can specify which number to use for your calls with a contact. Follow these steps:
- Tap the contact.
- Tap Preferred Cellular Plan.
- Tap the number you want to use with that contact.
The Icon, that allows you to chose the one of your numbers only shows up when you start a new conversation. It might help to delete the old one and to start over. But still, in my opinion it is an unfinished feature. Because I expect to change number in an existing conversation. I don’t want to lose the history.
I just made the switch to dual SIM as well and what a pain! In any case, I experienced the same thing as everyone else but one thing that helped me thus far was to have a person send me a message on my new number which switched it to the right line. As soon as they sent me a message on my new number a message "Number changed to Personal" ("Personal" is what I labeled the line) appeared in the thread.
I've tested only with individuals, so not sure how to tackle groups. Maybe have each person in the group send you and individual message to the "right" number, which will then maybe switch the group chat to iMessage?
Also, I'm sure you know this, but it's worth mentioning that you should ensure that iMessage is set to use the right number.
I have the same issue, setting the default to use a specific line still uses the other in an existing conversation thread. And the apple support document shows a label in the thread you can use to switch that does not exist. Not sure if it’s a bug or unfinished but it’s a big issue.
also not being able to use FaceTime and messages with both SIMs is a big issue unfortunatly. This is not fully baked.
For some reason the conversation switched to the correct number and switched back unfortunately.
It must be a bug since the number of the conversation is set to „private“ and „private“ does not use iMessage so pictures will be send via mms and the recipient receives the mms from my „business“ number.
Can an anyone help?
Hey. Thanks for your reply.
I did change the Standard-Account to „Privat“ (= Private) in the contact:
Tapping on the „i“ in iMessage shows, that „Geschäft“ (= Business) is used for the conversation:
Agreed and that isn’t an acceptable solution. The support document implies there is an indicator when the thread switches from one to other that also allows switching back, but it’s not there.
