Reliable Phone Numbers for Make.com Scenarios
Ensure your Make modules never fail a WhatsApp Business check. Deploy a real UK carrier number that bypasses VoIP restrictions.
The Problem: When configuring triggers and modules in Make (formerly Integromat) that rely on WhatsApp Business, you need a dedicated phone number to authenticate the API. If you use a cheap, disposable number, your scenario is at risk.
Why VoIP Fails: WhatsApp Business actively bans recycled VoIP numbers. Even worse, if you use a temporary number and lose access to it, WhatsApp will eventually recycle the number to a new user, instantly deleting all your scenario's chat history and breaking your API connection.
The Solution: SecondSIM issues real UK carrier-grade numbers via eSIM. Your Make.com scenarios get a permanent, non-VoIP identity. As long as your subscription is active, you retain total ownership of the number, ensuring your WhatsApp Business API connection remains stable and your chat history is never wiped.

Technical FAQ
Is this better than Twilio for Make.com?
Twilio provides VoIP numbers, which are frequently blocked by WhatsApp and banking APIs. SecondSIM provides a physical carrier connection (via eSIM), bypassing VoIP blocks completely.
Will I lose my chat history?
With VoIP or temporary numbers, losing access means losing your chat history. With SecondSIM, you keep the number permanently as long as your subscription is active, securing your data.
Do you offer an API to receive SMS directly into Make?
No. SecondSIM provides the underlying carrier identity (the eSIM). You must install the eSIM on a smartphone to receive the initial verification SMS, after which you connect the verified account to your Make modules.
What if I want to cancel?
You can cancel anytime. There are no contracts. We also offer a 7-day money-back guarantee if the number fails your initial verification.
Can I use this for services other than WhatsApp?
Yes. Since it is a real UK mobile number, it works for Stripe, Google, bank 2FA, and any platform that aggressively blocks virtual numbers.
