Client advice.
Agency-owned numbers.
Deploy real UK mobile numbers to your consulting team in 60 seconds via eSIM. Equip associates with dedicated WhatsApp Business for client engagements while retaining full ownership of client contacts and history.
Three problems, one line
Associates leaving with client address books
When consultants communicate on personal WhatsApp, client relationships leave with them when they exit. With SecondSim, your agency owns the number and can reassign it to a replacement hire in seconds.
Dozens of messy monthly mobile expense claims
Finance teams shouldn't spend hours checking £10–£15 reimbursable personal phone receipts. SecondSim consolidates all consultant lines into one clean, VAT-compliant monthly corporate invoice.
Carrying two bulky iPhones to client sites
Buying and insuring secondary corporate work phones is expensive and annoying for consultants traveling between client offices. SecondSim runs cleanly as an eSIM on their existing smartphone.
“We run a management consultancy in London with 12 associates. Giving consultants SecondSim on their own iPhones eliminated mobile expense claims entirely. More importantly, when an associate moved on, our client WhatsApp history stayed with our agency.”
Equip your practice in minutes.
Add consultant emails, send 1-click install links, and have your team communicating via dedicated agency lines before tomorrow's client presentation.

How does central billing work for consulting teams?+
All consultant lines are grouped under one central dashboard with a single monthly VAT invoice. You can add or remove team lines as project requirements change.
What happens to client chats when a consultant leaves?+
Your agency owns the phone number. When an associate leaves, you can instantly reassign the number to an incoming consultant, preserving client relationship continuity.
Do consultants need secondary company phones?+
No. SecondSim deploys via eSIM directly to your consultants' existing smartphones. They maintain their personal SIM alongside their dedicated client line with zero hardware bulk.
Can associates run personal and client WhatsApp on the same phone?+
Yes. Consultants run personal WhatsApp on their personal number and download the official WhatsApp Business app linked to their SecondSim line on the exact same device.
Can we port our existing agency numbers to SecondSim?+
Yes. We support standard UK PAC porting. If your consultancy already has numbers on legacy carriers, you can port them directly into SecondSim eSIMs without downtime.
