The Virtual Landline (VLL) is a fantastic way to establish your business presence, but when your business grows and you find yourself making more outbound calls, you might want the full power of the ONSIM Landline SIM.
The transition is completely seamless—you keep the same number your customers already know, but unlock the full capabilities of the ONSIM network.
🚀 Why Upgrade?
The Landline SIM is our flagship service. It removes the "Inbound-Only" restriction of the VLL and turns your mobile into a professional business handset.
With the Landline SIM, you unlock:
Two-Way Landline Calling: Make and receive calls using your 01, 02, or 03 landline number directly from your phone’s native dialler.
Native Integration: No apps, no VoIP, and no complicated PBX systems. It works exactly like a standard mobile SIM, but with the identity of a landline.
Increased Allowance: Benefit from a fair usage policy of 5,000 minutes per month for both inbound and outbound calls.
Maximum Reliability: Calls are routed over the cellular voice network, not the internet, ensuring crystal-clear quality even in areas with poor data.
