Review summary

SLYNUMBER reviews show mixed sentiment. A minority praise reliability, service quality, and perceived usefulness, describing it as a 'great' or 'wonderful' app. However, the majority complain about a paid‑only model with no real trial, payment and number provisioning failures and refunds, frequent bugs and sign‑in/Google service issues, weak customer support, and security/trust concerns. The recurring pattern is a divide between favorable impressions of features and significant operational and trust problems that deter many users.

Pros

Generally reliable performance; several reviews say the app 'works properly' and is overall reliable.
Positive service quality; users describe 'good service' and 'reliable clean service'.
Some users value the app's features and potential usefulness (number-related capabilities and related functionality).
Overall positive sentiment in multiple reviews ('great app', 'it's wonderful', 'very good app').

Cons

Not free; no usable free trial, forcing upfront subscription before testing features.
Payment/number provisioning problems: paying without receiving a number, porting holds, and refund delays.
Frequent reliability issues and glitches: sign-in failures, broken Google sign-in/Google Pay, glitches, slow/missing notifications, and poor call quality.
Weak customer support and trust concerns: lack of clear contact options, scam allegations, and account restrictions.
Security concerns and privacy issues: claims of not meeting security standards.
