Two iPhones sharing one number would solve so many work/personal headaches.

Handoff for phone numbers would fix dual-SIM chaos.

Carrier support will make or break this feature.

Work phone + personal phone sharing one number is the dream.

Privacy controls better be crystal clear for shared numbers.

Hope SMS/MMS/RCS all follow cleanly across devices.

iMessage already does this vibe — extending to cellular is huge.

Travel with a mini + main phone finally makes sense.

Needs rock-solid continuity when one device is offline.

Enterprise MDM policies are going to fight this hard.

If FaceTime/audio handoff already works, this is the next step.

Spam filtering across both devices better stay synced.

eSIM + Handoff could retire physical dual-SIM trays forever.

I'll enable it day one if carriers don't gatekeep.

Focus modes need to know which device is 'primary'.

This is the Continuity feature I've actually wanted for years.

Battery hit from keeping two radios live could be real.

Call screening should follow the active handset, not both.

Quietly one of the biggest iOS 27 quality-of-life bets.

If it works internationally I'm upgrading both my phones.
