China Mobile / Unicom / Telecom prefixes
Common carrier prefixes and how MVNO numbers appear in region lookup.
Typical Mobile / Unicom / Telecom ranges exist, but always trust the lookup result over memorized lists.
After number portability, the user may have switched carriers while the prefix DB still shows the original one.
MVNO numbers are labeled as virtual carriers; region still comes from the prefix city.
Avoid entering other people’s full numbers on untrusted sites; this tool keeps processing local.
