With multi-sim phone, sms from auto-selected sim1 is displayed -?-, not sim1, though not in all cases

Dear Tibur Kaputa,

With a dual-sim config in my phone, where:

1. default sms-text is [sim1]
2. when sending a text, New message instance, to my [sim2], the source of sim1 is displayed like [?].
3. in the return conversation of my sim2-contact, the source sim is displayed correctly.
4. When receiving a sms-message on sim1, [sim1] is correctly displayed, and with quite instant replies grouped. 4.a but when sending with a timely delay the [?] is displayed again.

I tried to switch sim1 and sim2 to possibly solve the issue.

attached are a few screenshots to clarify my issue.

please let me know again if my issue explanation is unclear (again), I do kind of like that. hopefully my descriptions will be more understandable. ;-)

With kind regards,

Pieter Joan
