Secure Phone Numbers for ChatGPT Bots
Connect your OpenAI-powered bots to WhatsApp Business using a real UK carrier number that never gets blocked for being VoIP.
The Problem: You are building a custom ChatGPT bot (using the OpenAI API) and want it to communicate with users on WhatsApp. To set up the WhatsApp Business API, your bot requires a unique phone number to receive the verification SMS.
Why VoIP Fails: OpenAI developers often try to use cheap virtual numbers. However, Meta (WhatsApp's parent company) strictly enforces anti-spam policies. They cross-reference numbers against telecom databases, immediately identifying and permanently banning VoIP and virtual landlines.
The Solution: SecondSIM provides real, carrier-grade UK mobile numbers via eSIM. Because our numbers sit on a Tier-1 cellular network, Meta recognizes them as legitimate physical mobile phones. Your ChatGPT bot gets a highly trusted, permanent identity that sails through WhatsApp's verification process.

Technical FAQ
Does this work for OpenAI SMS verification too?
Yes. If you need a phone number to verify your own OpenAI developer account, a SecondSIM number will pass the SMS check perfectly since it is not VoIP.
Is there a risk of the number being recycled?
As long as you maintain your SecondSIM subscription, the number belongs to you. We do not recycle active numbers, ensuring your bot's identity remains secure.
Do I need a second smartphone for the bot?
No. You can install the SecondSIM eSIM on your primary smartphone alongside your personal SIM. Once the WhatsApp Business account is verified, your bot runs in the cloud.
What if the verification code doesn't arrive?
Our numbers run on a Tier-1 UK network with excellent SMS delivery rates. If you encounter issues verifying your required service, we offer a 7-day money-back guarantee.
Is this a monthly subscription?
Yes, plans start at £4.99/month, and you can cancel anytime. There are no hidden fees or long-term contracts.
