Device regulatory compliance
Regulator orders on devices are executed in the network, with every transaction recorded.
The demand on the operator
The regulator requires blocking reported devices, applying national and international lists and reporting with evidence. Every order must reach the network without affecting legitimate devices.
ATC's response
Sx-EIR applies lists by IMEI and by type-approved model at every network check. Every response is recorded and presented by area in compliance dashboards.
Regulatory framework · Latin America
What each regulator requires of the operator on the IMEI, IMSI and MSISDN
Seven countries, one trend: from blocking the IMEI to linking IMEI–IMSI–MSISDN to an identified holder. Sx-EIR applies on the network the rule each regulation sets and records every response.

Anatel · Agência Nacional de Telecomunicações
CEMI (national register of barred devices), the Celular Legal project and Anatel Resolution 777/2025
- Activate only devices with certification accepted by Anatel and detect irregular ones.
- Notify the user of an irregular device by SMS and block it after 60 days.
- Block devices reported stolen or lost and replicate them in the CEMI for all providers.
- Block and observation lists synchronized with the national register.
- Subscriber notice and scheduled blocking, with every response recorded.
Regional mechanisms
- GSMA Device RegistryPractice FS.45 asks operators to upload their reports and download the global IMEI block list every hour.
- Andean Community · Decision 786Bolivia, Colombia, Ecuador and Peru must exchange stolen-device reports daily and block within 48 hours at most.
- 2025–2026 trendChile and Peru move from the IMEI alone to the IMEI–IMSI link; Mexico identifies the holder of each mobile service.

Technical dossier under confidentiality
Configuration, interface and deployment detail, in a document for your team
Configurations, interface requirements per module, reference architecture, sizing, the migration plan and the compliance table for tender pre-qualification are delivered in a dossier under a confidentiality agreement, after a first conversation with the ATC team.
How it operates in the network
Current lists
Lists from the operator, the regulator and international sources are integrated and migrated from the previous platform.
Response in the network
The switch queries the IMEI and Sx-EIR responds: allowed, observed or blocked.
Traceability
Every transaction is recorded and available for audit and regulatory reporting.
Results for the operator
- Regulator orders executed in the network
- Legitimate devices unaffected
- Reports with evidence of every response

Data is processed on the infrastructure the operator designates, under its control.
ATC reviews the platform the operator prioritizes and proposes the appropriate configuration. Sizing and review are provided at no cost.
- Review of the platform and the network interfaces
- Sizing according to the operator's infrastructure
- Staged proposal: module, platform or delegated operation
