Apple chose to implement it like that with least changes to existing implementation while adding a new feature, on the very first launch. They might extend functionality in the future.

According to Apple support document, you can’t send iMessage on the secondary line. Are you positive your texts on the secondary line are being received as blue?

Yes, for sure. However, so far, they are all with already established contacts. Time will tell if new contacts only come though as SMS texts on the second line (primary line is set for data and iMessages).

I recently swapped from 2 x iPhones for personal/work to a single XS Max with eSIM and a physical SIM. I originally used the same iCloud account on both phones and could send/receive iMessage from both numbers on both phones. Now I can only send/receive iMessages on the primary number. It's a massive limitation for me and a real pain. I really hope Apple fix this soon as a single iCloud account can certainly work with more than one number associated - its what I used to do. So its just a software issue...

If anyone has a workaround / hack to enable both numbers on iMessage when using dual SIM then I'd be very keen to find out!

They will fix it, but you have to buy faster and brighter iPhone XS-II (not ii , read it 2 :) , and hold it different )

I have tested this also. I have a personal number setup as eSIM and Business number setup as Secondary. All my contacts, business and personal have the default line as personal. I don't know how to change this by bulk. Right now i would have to go into every contact and change the default to Business for all my business contacts.

I tried texting a coworker, the text sent as blue (iMessage). Turns out it used my personal number. The only way I have found to get it to use my work number is to change the contact to default to business. Then delete any messages I have from that person, and initiate a text to them. This is horrible.

Anyone find a better solution to this?

Not anything I have found. What you describe appears to be the intended behavior.

What is worse is if that person sends a text message to your work number - it switches to business line and you can’t then iMessage them from personal until you delete the thread and start again.

I have been using the Hong Kong XS Max for the last two months (dual physical sims) - I was hoping the e-sim might behave differently

Since they are already established contacts, the default number is your primary line. So if that contact was added to your phone when you only had your primary line, it will default to the number for calls and texts. Any numbers you add to your contacts or call/text after you set up dual sim will ask you which line you want to use, and you will probably notice when you chose secondary number for texts it will not send as an imessage

Isn’t there an option in iMessage settings to initiate new conversations from any email address instead of a number? I guess that doesn’t solve the problem of having to remove all the messages and set a default choice on a contact by contact basis...you’d have to choose your personal or business email as default...interesting one...and no real easy workaround...
