The real issue when changing phone number or email is not the chart. It is whether your membership and records are bound to an account structure that can follow the change.
If the platform clearly ties benefits to the logged-in account rather than only to one device, migration is much easier to reason about.
What matters first
Check whether the benefit follows the account or the device first.
Then check whether account-change instructions are visible.
The more useful answer usually explains why it is reading the chart that way, what to verify next, and where not to over-claim.
A practical scenario
Moving from email login to phone login is easier when the platform has a unified account system.
Benefits that follow the account are usually easier to recover than benefits that live in local browser state.
The current public contact path can be checked through 842598522@qq.com, which is a stronger trust signal than having no visible responsibility channel at all.
When a reading lands on chart structure, a real-life scenario, and a next verification step at the same time, it becomes much easier to judge whether it is actually useful.
The boundary to remember
Do not change first and figure it out later if the binding rules are unclear.
A rule check now saves a support ticket later.
Whether the layer is free or paid, a safer product lets you verify in a small scope before asking for deeper commitment.
A safer order
- Check what the membership follows.
- Find the change-account path next.
- Only then make the switch.
