The hidden cost of company phones.
A fraction of a traditional contract.
The average UK corporate contract with a physical handset costs around £45 per employee per month — before upfront device purchase, insurance, and 24-month lock-ins. SecondSim moves your team onto carrier-grade mobile numbers on their existing phones from £5.00/seat/month.

Do employees have to give up their personal number?+
Not at all. SecondSim sits alongside their personal SIM on the same phone. Two active numbers on one device — one personal, one strictly for work.
How many seats can I manage?+
As many as you need. Add seats one at a time as your team grows. No minimum, no maximum seat limit.
Can I keep a number if an employee leaves?+
Yes. Park the number for just £2.99/month to preserve it, then instantly reassign it to a new hire when the time comes.
Is there a free trial?+
We offer a 7-day money-back guarantee. If it doesn't work perfectly as promised — verified by WhatsApp, your bank, or any platform — you get a full, refund if verification fails.
Do the numbers work for WhatsApp Business?+
Yes, absolutely guaranteed. Our numbers are 100% real, non-VoIP UK mobile numbers — the exact technical requirement to verify and run WhatsApp Business.
Is team deployment self-service?+
100% self-service. Select your seat quantity, complete payment via Stripe, and email 1-click eSIM activation links to employees — all in under 2 minutes without contacting sales.
Are these real UK mobile numbers?+
