Business call recording on mobile
Business call recording, delivered at network level
Record every business call automatically, no app on the device, no Wi-Fi dependency, no missed recordings because someone forgot to enable it. ONSIM Business Call Recording captures inbound and outbound voice calls (and SMS) on a UK mobile SIM at the network level, ready for retrieval, audit or export.
Suitable for SMBs, customer-facing teams, and regulated firms that need evidential-quality recordings.
Why network-level recording, not an app?
Nothing to remember
Apps depend on the user starting the recording on each call. ONSIM records every call automatically, there's no way to forget.
Consistent across the supported estate
Because recording happens on the network, not the handset, there are no app permissions to manage, no OS-update breakage and no IT support tickets. The SIM/eSIM runs on ONSIM-supported iPhone, Samsung and Pixel handsets, see the full list at supported devices.
Evidential quality
Recordings are made on dedicated network infrastructure, stored centrally with tamper-evident retention, and retrievable for audit. Suitable for regulatory and legal use cases.

Who uses ONSIM business call recording
Customer-facing teams
Sales, support, account management, anywhere call quality, training and dispute resolution matters. Records every call without changing how reps work.
Regulated practices
FCA-regulated firms, solicitors, accountants, healthcare practices, anywhere recordings are required for compliance or evidential reasons. See Mobile Compliance Recording for the regulated configuration.
SMBs that need a paper trail
Trades, professional services, lettings, anyone who's ever been "he said / she said" with a customer. Recording every call from the same business number means there's always a record.
How ONSIM's pricing compares
Most mobile-call-recording quotes come in as a stack of line items, a base per user, then storage, then a search/replay licence, sometimes per-minute recording surcharges. When it all adds up on the buyer's spreadsheet, the "cheap" base turns into something quite different. ONSIM is a flat price with everything included.
| Line item | Quote-only, typically layered | ONSIM SMB |
|---|---|---|
| SIM / eSIM per user | Separate mobile plan | Included |
| UK minutes and SMS | Metered or separate bundle | Included |
| Call recording (voice + SMS) | Recording licence per user | Included |
| Secure archival | Storage licence, often per GB or per month | Included |
| Search & replay | Separate portal licence per admin | Included via ONSIM dashboard |
| Number porting | Often a per-number fee | Included |
| UK-based support | Support-tier dependent | Included |
| Headline price | Quote required | £20/user/month + VAT |
Most vendors in the mobile call recording category do not publish per-user pricing publicly and require a sales call for a quote. The line items above describe the common commercial pattern rather than any specific vendor's rate card. ONSIM's £20 line is a flat monthly figure with all listed items included.
Pricing
Most SMB customers pay £20/user/month + VAT, one line, complete solution. That covers the SIM or eSIM, UK minutes and SMS, the recording itself, secure archival, and search & replay via the ONSIM dashboard. No separate archive licence, no per-minute recording surcharge, no add-on hunt for a search tool.
Enterprise deployments with long retention, dedicated third-party archive integration or bespoke compliance scope are quoted separately.
Frequently Asked Questions
The questions buyers most often ask before signing up.
What is business call recording?
Business call recording is the practice of capturing and storing inbound and outbound business phone calls for training, evidential, customer-service or regulatory purposes. For mobile, recording can happen either through an app on the device or at the network level, ONSIM does it at the network level so recordings are captured automatically without anything to install or remember to enable.
Is it legal to record business calls in the UK?
Yes, with conditions. Under UK GDPR and the Data Protection Act 2018, businesses can record calls if they have a clear lawful basis (typically legitimate interest or contractual necessity), they inform the other party that the call may be recorded, and they store recordings securely with a defined retention period. Regulated industries (financial services, legal, healthcare) have additional requirements, see our guide to UK call recording law.
How is ONSIM different from a call recording app?
Apps depend on the user remembering to start the recording, the app having the right permissions, and the device having battery and storage available. Anything one of those fails and the call is lost. ONSIM records at the network level, the recording happens automatically on every call, with no app on the device. Recordings are stored centrally, ready for retrieval, audit or export.
What does business call recording cost?
Most SMB customers pay £20/user/month + VAT, a complete solution covering the SIM/eSIM, UK minutes and SMS, the recording, secure archival, and search & replay via the ONSIM dashboard. Nothing separately licensed, no add-on hunt. Enterprise deployments with long retention, dedicated third-party archive integration or bespoke compliance scope are quoted separately at quote.onsim.uk or +44 333 880 4008.
Can recordings be exported to our archive?
Yes. Recordings can be retrieved via the ONSIM dashboard or pushed to your existing archive system (S3, SFTP, or specific compliance archive vendors) via our Developer API. Speak to sales about specific integrations during the quote process.
How long are recordings retained?
Retention is configurable per account, typically 6 months to 7+ years depending on your regulatory requirements. Default UK business retention is usually 6 months under DPA principles; FCA-regulated firms typically need 5 years (and 7 years for MiFID II transactions). Confirm during the sales conversation what's appropriate for your regulatory regime.
Does it work on iPhone, Samsung, Pixel?
Yes, on supported handsets. Because recording is done at the network level, not via an app, there is no app permission or OS-update issue on the device, but the SIM/eSIM itself only runs on ONSIM-supported handsets. Check the full list at supported devices before ordering.
Can we record SMS too?
Yes. ONSIM Mobile Call & SMS Recording captures both voice calls and SMS messages on the same plan, both inbound and outbound.
Do you offer compliance-grade recording for FCA-regulated firms?
Yes, that's our Mobile Compliance Recording offering, designed specifically for FCA, MiFID II and PCI-DSS contexts. See our FCA call recording compliance page for the regulatory specifics.
