Secure the app millions of subscribers carry.
A carrier self-care app touches identity, billing, usage and account control at national scale - so a single binary-level flaw becomes a fraud engine. Mobexa tests the exact build subscribers install, proves where SIM, billing and API flows hold, and maps it to GDPR and KVKK.
Where carrier apps get abused
At subscriber scale, the device and the API edge are the surfaces fraudsters study first.
Subscriber & billing
Identity, MSISDN, usage and billing data stored or transmitted without proper protection.
SIM, eSIM & APIs
Provisioning, device binding and account-control APIs - the flows that turn a flaw into takeover or fraud.
SDK supply chain
Bundled analytics and partner libraries inventoried and matched to known CVEs - third-party risk at scale.
Coverage that matches your subscriber base
A flaw in a carrier app is multiplied by millions of installs. Mobexa runs on every release, re-checks the dependency set, and produces evidence tied to the privacy and security duties a regulator and your own assurance team expect.
- Every release tested, gated only on new criticals.
- GDPR, KVKK, ISO 27001, NIST mappings on every finding.
- SIM, eSIM and API-flow coverage proven at runtime.
- Self-hosted option for sensitive subscriber data.
One picture across the estate
Self-care, top-up, TV and IoT companion apps - findings land in one deduplicated backlog with severity, ownership and SLA timers, giving assurance leadership a single, reportable view across Android and iOS.
The exposure pattern of subscriber self-care apps
A telecom app is an identity system for millions of subscribers: SIM, billing and account control in one place. The binary usually carries more privilege than anyone intended.
Subscriber identifiers over-exposed
MSISDN, IMSI-derived values and contract identifiers cached on device and echoed through analytics calls.
SIM and eSIM flows weakly gated
Number-change and eSIM activation flows relying on client-side checks that a modified build can skip.
Internal API topology disclosed
Hardcoded internal hostnames and staging gateways mapping the operator estate for an attacker.
Legacy WebView bridges
JavaScript bridges from campaign and top-up webviews into native code, reachable from injected content.
Telecom mobile security, answered plainly
How do you secure a telecom self-care app?
You test the build subscribers install. Mobexa decompiles the shipped app, runs it on an instrumented device, and finds where subscriber identity, billing data and provisioning tokens are exposed - weak storage, hardcoded keys, unsafe SIM and eSIM flows, exposed APIs - and maps each finding to the regulation behind it.
Why are carrier apps a high-value target?
A self-care app reaches a huge subscriber base and touches identity, billing, usage and account-control functions. At that scale, a single binary-level flaw - an exposed key, a weak token, an over-trusting API - becomes a fraud and account-takeover engine, which is exactly the surface Mobexa is built to read.
Do you cover SIM, eSIM and provisioning flows?
Yes. Mobexa inspects how the app handles SIM and eSIM provisioning, device binding and the secrets behind them, and proves at runtime whether transport security and request integrity actually hold for those sensitive flows.
What evidence does it produce for audits?
Findings map to OWASP MASVS and roll up to GDPR, KVKK, ISO 27001 and NIST, with a traceable trail from the headline risk to the proof - the documentation a telecom security and privacy review expects.
Test your self-care app before fraudsters do.
We will run a build through static, dynamic and API-flow analysis, map it to your privacy duties, and show the gate in your pipeline.
