The roaming problem with iMessage

UPDATE

It appears I might have been too hard a judge: having just sent an iMessage, iPhone was unable to deliver it for a few minutes, then automatically sent it as SMS. Clearly this doesn’t work all the time, which is a shame.

The scenario: you’re using iMessage to communicate with someone in the
morning, then they travel to another country. You reply to a message
they’ve sent; not specifying to send a message using SMS or iMessage,
only to realise they’re not going get it until they re-connect to
data.

I do not believe there’s way to tell iOS to send using SMS, and it,
rather irritatingly, only checks for your data status, and not at
least the roaming status of your conversation recipient. Not without
disabling iMessage, switching back to the messaging application, and
then re-enabling iMessage when done.

Not the best implementation of SIP.

Brief Sennheiser Momentum Sport Data Analysis

Sennheiser released their Momentum Sport headphones in 2024-04, an interesting partnership between Polar (they who invented the chest-worn ECG) and an audio company. Historically, the ear has been an excellent point to measure both temperature and heart rate from, so logically these headphones should have been able to readily replace
