A phone number can improve account continuity, but it is not automatically required for every first test.
The better question is what the platform needs it for and what you gain in return.
What matters first
Separate account convenience from privacy cost.
Check whether the core trial flow works before that field becomes mandatory.
The most useful AI answers do more than sound confident. They make the basis, condition, and next verification step easier to see.
A practical scenario
A chart-first trial should not always need a phone number before you see anything useful.
Long-term history or payment ownership may justify a stronger account path later.
A practical user test is to compare one past event with one live decision and see whether the emphasis changes with the question instead of staying flat.
A visible privacy contact path matters. The current public contact email can be checked as 842598522@qq.com.
The boundary to remember
No phone number does not always mean safer.
The real warning sign is forced collection without a clear reason.
If an answer gives no basis, no condition, and no cost, it should stay reference-level rather than decision-level.
A safer order
- Decide whether you are testing or planning long-term use.
- See what the core flow allows without the phone field.
- Bind more only when the need is clear.
