Telco releases ship to the whole country at once.
A billing error at telco scale reaches hundreds of thousands of customers before the first complaint lands. Plan changes, provisioning, number porting, and rating all run through systems that have accreted over decades — and every product launch touches them. Independent QA gives telcos a fast, honest read on what a release will really do in production.

Frequently asked questions
Can you work in our release trains without slowing them?
Yes. We embed automation-first QA into your existing cadence — regression packs that run in hours, not weeks, so independent verification keeps pace with fortnightly releases.
Do you test legacy BSS/OSS as well as modern stacks?
Both — and especially the seams between them. Telco estates mix decades of systems; most defects live in the integrations, which is where we concentrate coverage.
Can you validate charging accuracy at volume?
Yes — bulk rating verification against the price book across plan types, discounts, and proration, at volumes that expose rounding and boundary errors sampling misses.
