BLUF:

Telecom providers process extensive personal data: customer details, call records, location data, billing information. UK GDPR applies fully. If you use AI for fraud detection or service decisions, Article 22 requires human oversight. ICO can fine up to £17.5 million or 4% of global turnover.


Personal Data in Telecoms

Communication providers handle several categories of personal data:

Data TypeExamplesSensitivity
Customer DataName, address, payment detailsStandard
Traffic DataCall records, timestamps, numbers calledHigher (reveals behaviour)
Location DataCell tower data, IP addressesHigh (reveals movements)
Content DataVoicemails, messagesVery High
Billing DataUsage patterns, spend historyStandard

Key GDPR Principles for Telecoms

Lawful Basis

Document why you process each data category:

  • Contract: Processing customer details, billing, service delivery
  • Legal obligation: Law enforcement requests, Ofcom compliance
  • Legitimate interest: Fraud detection, network security
  • Consent: Marketing, optional services, location features

Data Minimisation

Only collect what's necessary. Telecom-specific considerations:

  • CDRs: Retain necessary fields, not full recordings
  • Customer verification: Minimal ID data for KYC
  • Location: Only if needed for service or with consent

Storage Limitation

Define retention periods for each data type:

Data TypeTypical RetentionLegal Basis
CDRs (billing)12-24 monthsContract + disputes
CDRs (law enforcement)12 monthsData Retention Regulations
Customer contracts6 years post-terminationLimitation Act
Marketing consentUntil withdrawn + 6 monthsEvidence of consent

Article 22: Automated Decision-Making

If you use AI or automated systems to make decisions affecting customers, UK GDPR Article 22 applies:

What Triggers Article 22?

  • Automated credit scoring for service approval
  • AI fraud detection that blocks accounts
  • Automated service suspension for non-payment
  • Risk scoring that affects pricing or access

Requirements

  • Human oversight: Human review for significant decisions
  • Right to explanation: Explain decision logic to customers
  • Right to contest: Mechanism to challenge automated decisions
  • DPIA: Data Protection Impact Assessment required

TELECOM COMPLIANCE Approach: Our Telecompliance AI implements Human-in-the-Loop (HITL) triggers. When the system detects a high-risk decision (service suspension, fraud block), it pauses and generates a Decision Justification Brief for human approval.


Data Subject Rights

Customers have rights over their personal data. Telecom-specific responses:

RightResponse RequiredTelecom Considerations
Access (SAR)30 daysProvide CDRs, account history
RectificationWithout undue delayUpdate contact/billing details
ErasureWithout undue delayMay conflict with retention obligations
Portability30 daysExport account data in standard format
ObjectionWithout undue delayMarketing opt-outs, fraud processing

Exemptions

You can refuse some requests where legal obligations apply:

  • CDRs retained for law enforcement purposes
  • Data needed for ongoing legal disputes
  • Records required by Ofcom regulations

Data Processor Agreements

If you use third parties (cloud platforms, billing systems), ensure Data Processing Agreements cover:

  • Processing only on documented instructions
  • Appropriate security measures
  • Subprocessor approval and flow-down
  • Assistance with data subject requests
  • Return or deletion at contract end
  • Audit rights
