Questions.
Anything else? Email us.
Is SecondSim really non-VoIP?+
Yes. SecondSim provides a genuine UK mobile identity using real network routing codes (IMSI range). WhatsApp filters and bans virtual VoIP numbers — SecondSim passes these security gates natively because we are a real carrier-grade mobile number.
Will I lose my personal WhatsApp chats?+
No. Your personal WhatsApp stays exactly as it is. You download the WhatsApp Business app and verify it separately with your SecondSim number. Both run side-by-side on the same phone.
Does it work on iPhone and Android?+
Yes. Any eSIM-compatible smartphone — iPhone XR or newer, Samsung Galaxy S20 or newer, Google Pixel 3a or newer. Setup is identical on both platforms.
Can I move the number to a new phone later?+
Yes. Contact support and we'll issue a new QR activation for your new device. Your number stays the same.
What if WhatsApp doesn't verify?+
You get a 100% refund. If your SecondSim number isn't verified by WhatsApp within 7 days, we refund in full. No questions, no hassle.
