Key takeaways for Second Phone Number - Dou Line
Where is it heading?
The virtual number market is consolidating around providers with transparent billing and responsive support. Dou Line's current posture is exposed: unresolved billing failures will likely trigger platform-level enforcement actions before the next major release cycle.
- Systemic billing failures reported by users lead to refund requests, which compounds the rating drag already visible on the Android platform.
