Whether you’re joining us for the first time or adding more lines to your account, here is how to get multiple SIMs:
1. During Your Initial Sign-Up
You can order up to two SIMs in a single checkout session.
Configure your first SIM (Plan, SIM type, Device, and Number).
Look for the + Additional Plan button located just above your Order Summary.
Configure your second SIM and proceed to checkout.
2. For 3+ SIMs
To order three or more SIMs, you will need to complete your first order, then use your dashboard to add more.
Step 1: Complete your initial order for 1 or 2 SIMs.
Step 2: Log in to your Online Dashboard.
Step 3: Click the Add SIM button.
Step 4: Follow the step-by-step guide to place your next order.
💡 Pro Tip: Ordering in Bulk
Due to security and system limits, each checkout is capped at 2 SIMs.
Need 4 SIMs? Place your first order for 2, then immediately place a second order for 2 via the dashboard.
Need 10+ SIMs? For larger quantities, please contact our support team at support@onsim.uk for a streamlined setup.
