Kundenabwanderung durch langsame oder fehlerhafte Rufnummernportierung
Definition
Local number portability exists to facilitate competition by allowing customers to change providers while retaining their geographic numbers.[2][3][4] Where carriers mishandle LNP—through missed cutover windows, extended outages, or repeated re‑ports—customers experience significant disruption, particularly if the affected numbers are published business contact lines. Even if the port eventually succeeds, the perceived reliability of the provider suffers, increasing the likelihood of subsequent churn or down‑sell at contract renewal. For SMEs and enterprises with multiple lines, a single poor migration can trigger full‑portfolio moves on expiry. If a carrier has AUD 30 million per year in SME/enterprise fixed‑voice revenue and 5–10% of those customers undergo LNP‑related changes annually, and if 10–20% of those with poor porting experiences churn or significantly downscale, the indirect revenue loss can quickly reach into the hundreds of thousands per year.
Key Findings
- Financial Impact: Quantified (LOGIC): If 3,000 SME/enterprise customers (out of 30,000) experience LNP‑related changes annually and 10% suffer poor porting experiences, that is 300 at‑risk customers. With an average revenue of AUD 5,000 per year each and a 20% incremental churn rate among this group due to dissatisfaction, approx. 60 customers are lost, equating to AUD 300,000 in annual recurring revenue loss, not counting additional down‑sizing from customers who stay but reduce services.
- Frequency: Recurring; correlates with churn cycles, contract expiries and network migrations.
- Root Cause: Inadequate communication with customers about porting timelines and risks; insufficient contingency planning for critical numbers; limited monitoring of porting SLAs; manual errors causing avoidable outages.
Why This Matters
The Pitch: Australian 🇦🇺 telcos lose an estimated 1–3% of high‑value business customers annually due to poor number‑porting experiences. Robust, predictable LNP administration improves retention and protects recurring revenue.
