Why Solicitors Need a Considered Approach to Mobile
Legal work on a mobile is not the same as any other profession. Calls and messages often carry legal professional privilege, and a single lost handset can turn into an SRA-reportable data breach. The choice of contract, handset and policy matters more than the monthly price.
The right business mobile setup for a UK law firm usually needs to cover:
- Call recording for matters that require it (typically contentious or regulated work)
- GDPR-ready handset management via Mobile Device Management (MDM)
- Encrypted messaging that protects privileged communications
- Clear separation between the firm's number and any personal device
- Multi-line fleet control for practices with several fee earners and support staff
Consumer tariffs do not deal with any of this cleanly. A business contract, paired with the right firm policies, does.
Call Recording on a Business Mobile: What's Possible and What to Avoid
UK solicitors who need to record mobile calls have three mainstream options:
- Network-level call recording — available as a business bolt-on from EE, Vodafone, O2 and Three. Recordings sit in a secure portal, typically retained for 3-7 years depending on the plan.
- Cloud phone system (VoIP) with mobile extension — the firm's landline number rings through to a mobile app, and all calls are recorded by the VoIP provider (for example RingCentral, 8x8 or similar). This is the cleanest route for most law firms.
- On-device recording apps — not recommended for regulated work because retention, storage and audit trails are much weaker.
Under UK GDPR, PECR and the SRA Code of Conduct, any call recording must be:
- Notified to the caller at the start of the call (typically via an automated message)
- Stored securely with appropriate retention periods and access controls
- Auditable with a clear log of who accessed recordings and when
- Deletable on request in line with data subject rights
Most law firms pair a cloud phone system with a business mobile for this reason. We can quote both together.
GDPR, SRA and the Lost-Phone Problem
A solicitor's handset often holds emails, documents, client contacts, matter lists and sometimes case management system access. A lost or stolen phone is a live data-protection risk.
Business mobile contracts make the response much easier:
- Remote wipe via MDM from the first notification
- Passcode and biometric enforcement so a lost phone is not an open door
- Encrypted storage standard on iPhone and modern Galaxy devices
- Managed app lists so only approved apps (Outlook, Teams, case management) are enrolled
- Number retention — the number belongs to the firm, not the individual fee earner
Under SRA guidance, firms handling client confidential information should have a documented mobile-device policy covering these exact points. The practice's ICO registration and data-protection impact assessments should name mobile devices as in-scope.
Encrypted Messaging for Privileged Communications
Legal professional privilege can apply to mobile messages, but privilege does not create technical security on its own. Firms wanting encrypted messaging have two sensible routes:
- Signal or WhatsApp (both end-to-end encrypted) for quick client messages where appropriate — with a clear policy on what can and cannot be said via these channels
- Microsoft Teams or equivalent firm-controlled platform for anything involving documents, attachments, or long chains of advice
A business mobile contract does not change the choice between these — both work on any smartphone with a standard data plan. What matters is the firm's policy on which channel to use for what, and whether mobile chat logs are retained alongside email for matter records.
Secure Email and Case Management on Mobile
Most UK case management systems — LEAP, Clio, Osprey, Actionstep, Linetime, Tikit — have mobile apps that work on any iPhone or modern Galaxy on a standard business data plan. For security:
- Use the firm's managed Microsoft 365 or Google Workspace account, not a personal email
- Enable multi-factor authentication (MFA) on all log-ins
- Use the case management app's biometric lock where available
- Enrol the device in MDM so it can be wiped centrally
Data usage for legal apps is modest — typically well under 2GB per month per user — so a standard 20-50GB business data plan is more than enough once email, Teams and web browsing are included.
Multi-Line Deals for Law Firms
A three-partner high-street firm with paralegals, a legal secretary and a receptionist typically runs 6-10 mobile lines. Mid-size commercial firms run 30-100+. Multi-line business mobile discounts:
| Lines | Typical savings vs individual plans |
|---|---|
| 5-9 | 10-15 percent |
| 10-19 | 15-20 percent |
| 20+ | 20-25+ percent |
Shared data pools, single billing and centralised MDM usually pay for the switch to a business contract on their own. Contracts are 24 months, which is the UK business mobile standard.
Typical Pricing for Legal Practice Mobile Deals
Indicative ex-VAT pricing for UK law firms in 2026:
| Plan type | Typical cost | Good for |
|---|---|---|
| SIM only, 20-50GB | From around £11+VAT per month | Back-office staff and BYOD fee earners |
| SIM + iPhone 16 / Galaxy S25 | From around £35+VAT per month | Partners and client-facing solicitors |
| SIM + call-recording bolt-on | Add around £5-10+VAT per month | Any line handling recorded calls |

Frequently Asked Questions
Can solicitors record calls on a business mobile in the UK?
Yes. EE, Vodafone, O2 and Three offer call-recording bolt-ons on business mobile contracts, and most cloud phone systems used by law firms will record any call that passes through them. Any recording must comply with UK GDPR and PECR — typically by notifying the caller at the start of the call, storing recordings securely, and retaining them only for as long as needed. We can quote network-level recording or a paired cloud-phone plus mobile setup.
Are business mobile contracts SRA-compliant for solicitors?
A business mobile contract is not itself "SRA-compliant" — compliance sits with how the firm uses the device and handles client data. What a business contract contributes is account-level control such as MDM, remote wipe, passcode enforcement, call recording and central billing. The firm still needs a documented mobile-device policy, ICO registration, MFA on client systems and a lost-device procedure.
Does legal professional privilege apply to WhatsApp and Signal messages?
Privilege can apply to messages on any medium if the content qualifies, but privilege does not create technical security. WhatsApp and Signal are both end-to-end encrypted, which reduces the risk of interception in transit, but firms still need a policy on what can be discussed on these channels and whether chat logs should be retained alongside email for matter records. A business mobile contract does not change this — both apps run on any smartphone.
How do I secure a solicitor's mobile phone against loss or theft?
Enrol every firm-issued or BYOD device in Mobile Device Management (MDM). Enforce a strong passcode or biometric lock, enable device encryption (standard on iPhone and modern Galaxy), install only firm-approved apps, and ensure the firm can remotely wipe the device. Business mobile contracts from all four UK networks support MDM out of the box.
Can law firms claim VAT on business mobile contracts?
Yes, if the firm is VAT-registered. A mobile contract taken in the firm's name and used for legal work is a fully tax-deductible expense, and 100 percent of the VAT can be reclaimed on business-only usage. For mixed personal and business usage, HMRC requires a reasonable apportionment of the reclaim.
What happens to a solicitor's mobile number when they leave the firm?
If the contract is in the firm's name, the number stays with the firm and can be reassigned or put on voicemail redirect. If the contract is in the individual's name (a common weakness of BYOD setups), the number and any client communication on it leaves with them. This is one of the strongest practical reasons for firms to issue handsets and hold contracts centrally.
Do law firms need call recording on every mobile line?
Not necessarily. Call recording is typically required only on lines handling regulated or contentious work, and is a common requirement on client-facing direct-dial lines. Partners, associates and paralegals handling non-contentious work often do not need recording on their mobile. We can split the fleet so only the lines that need recording carry the bolt-on, which keeps costs down.
