Customer Case Studies
Case Studies
Real deployments, real numbers where customers let us share them, anonymised where they don’t.
Children's residential care
A 60-home children's care provider cut response times across every site
Apps and static IP phones left a 500-staff children's residential care provider with missed calls, high costs and a compliance gap. ONSIM gave all 60 homes flexible telephony with full visibility.
Fintech
A global payments fintech consolidated mobile and recording onto one supplier
Operating across many countries with no central mobile provider and no native recording in most of them, a global payments fintech consolidated onto ONSIM - one supplier, native numbers and recording, smaller bill.
Recruitment
A 250-agent medical recruitment agency closed its call recording gap in under a week
With no access to call audio, a large UK medical recruitment agency carried real compliance and income risk. ONSIM Landline SIMs with recording closed the gap, feeding recordings straight into their own systems.
Banking
A multinational bank replaced clunky mobile recording across regions in 48 hours
A large multinational bank found mobile call recording patchy across its regions, expensive and cumbersome. ONSIM Landline SIMs with native recording went live in 48 hours - cheaper and more reliable.
IT services
QLine IT sees every customer call - recorded, transcribed and dashboarded
A 15-person UK IT support provider replaced ordinary VoIP with ONSIM Landline SIMs and hosted telephony, gaining real-time transcripts of every call and the data to prove issues get resolved.
