Carrier-Grade Identity for n8n Workflows
Bypass HLR lookups and VoIP blocks with a genuine UK Mobile Network Code (MNC) and clean IMSI range.
The Problem: Technical users deploying n8n workflows often hit authentication roadblocks when integrating with rigid APIs (like WhatsApp Business or financial platforms) that require SMS verification.
Why VoIP Fails: Standard programmable communications providers issue numbers from known VoIP ranges. When a platform performs an HLR (Home Location Register) lookup or checks the telecom routing data, it easily identifies the number as virtual and blocks the verification payload.
The Solution: SecondSIM provisions numbers from a Tier-1 UK Mobile Network Operator (MNO). This means your number has a legitimate Mobile Network Code (MNC) and a clean IMSI (International Mobile Subscriber Identity) range. To any external API performing an HLR lookup, your n8n identity appears as a standard, trusted physical handset.
Provisioning your n8n Phone Identity
Acquire Carrier Identity
Select a plan starting at £4.99/month. We dynamically assign a real UK mobile number from a Tier-1 MNO allocation.
Deploy eSIM Payload
Scan the provided QR code to install the eSIM profile on an iOS (2018+) or Android device. This establishes the physical network connection.
Intercept Verification SMS
Trigger the verification payload from your target API (e.g., WhatsApp Business). The SMS routes through the carrier network directly to your device.
Bind to n8n
With the service authenticated against a trusted carrier identity, link the resulting session or API token to your n8n workflow.
Technical FAQ
Do you provide the raw IMSI or Ki for programmatic access?
No. We provide a consumer-ready eSIM QR code. You must install the profile on a standard baseband device (smartphone) to terminate the connection and receive SMS.
Are these numbers MVNO or direct Tier-1?
Our numbers are routed through a Tier-1 UK carrier network, ensuring they pass strict HLR and line-type lookups as "Mobile" rather than "VoIP" or "Fixed-Line".
Can I route inbound SMS directly to a webhook in n8n?
SecondSIM provides the network layer, not the application layer. You receive the SMS on the physical device. You cannot natively webhook the SMS directly from our infrastructure.
Do you recycle numbers?
We quarantine and cycle numbers strictly according to Ofcom guidelines. As long as your subscription remains active, the number is exclusively assigned to you.
What is the commitment?
Zero lock-in. Cancel anytime. 7-day money-back guarantee if the number fails the specific verification you require.
