How to Manage Multiple Business eSIMs for Your Team

Last Updated: July 2026

Say goodbye to tracking bulky corporate phones. Discover how to instantly issue secure business communication lines to your startup team's personal devices.

The Danger of "Shadow IT" and Employee-Owned Numbers

When you ask staff to download cheap VoIP apps or buy their own secondary SIMs, you lose control of your business communications. This "Shadow IT" approach means numbers are disconnected when staff leave, client contacts are lost, and you are left managing dozens of disparate expenses.

Centralized eSIM Billing & Management

SecondSim solves this by bringing the real UK mobile network directly to your dashboard. Founders and Operations Managers can purchase blocks of Tier-1 carrier-grade numbers with a single centralized invoice.

No more courier deliveries for heavy work phones, and no more dropped calls from Wi-Fi dependent apps. Staff receive a native UK line right on their existing personal phone.

The 3-Step Process for Issuing Numbers

  1. Acquire Licenses: Select your bundle tier inside the SecondSim Team Dashboard.
  2. Provision via Email: Send a unique QR code payload directly to your new hire's inbox.
  3. Instant Scan: The employee scans the code and the business line establishes native call-routing capabilities side-by-side with their personal network.

Protecting Corporate Assets and WhatsApp Data

Because SecondSim numbers are true GSM lines, they pass all security checks for WhatsApp Business. This allows your team to keep client conversations entirely separate from their personal WhatsApp. When an employee departs, you simply revoke the QR profile and reassign the number to their replacement—ensuring you never lose a client lead again.
