🚀 Introducing ONSIM’s Virtual Landline (VLL)

ONSIM has always been known for one thing:
Making calling simple for small businesses.

Our flagship Landline SIM turns your mobile into a true landline phone — no apps, no VoIP, no diverts, just clean and professional calling.

Now we’re introducing VLL: Virtual Landline, a lighter, lower cost and more flexible option designed for businesses who want a professional landline presence without committing to the full Landline SIM straight away.

Think of VLL as:
Landline SIM (Light) — Start simple. Upgrade when ready.

🧩 Two Ways to Use VLL

VLL is designed to fit the way you want to work. You can use it in one of two modes:

1️⃣ Call Forwarding Mode

Perfect if you want your landline number to simply ring your mobile.

• Quick and easy setup
• Works on any phone
• Fair usage policy of 2,500 inbound minutes per month
• No apps or complicated systems
• Ideal for startups, sole traders, or “just need a number” situations

This mode gives you a professional landline presence at the lowest possible commitment level.

2️⃣ Inbound-Only SIM / eSIM Mode

If you want something more powerful — but still simple — you can choose to use an ONSIM SIM or eSIM that receives calls on your landline number.

• Your mobile phone rings directly on the landline number
• Fair usage policy of 5,000 inbound minutes per month
• See it’s a business call instantly
• A clean, reliable way to receive business calls

Note: This mode is inbound only — outbound calls are still made from your normal mobile number unless you upgrade to the full Landline SIM service and you must ensure that you have a supported device.

It’s a perfect “half step” between forwarding and the full ONSIM Landline SIM.

⭐ When You’re Ready, Upgrade to the Full Landline SIM

If you want the complete experience — where your mobile becomes your landline, including outbound calls showing your landline number — the upgrade path is seamless.

With Landline SIM, you get:

• Inbound and outbound calling on your landline number
• Unlimited inbound and outbound calls (5,000 mins/month Fair Usage)
• Maximum reliability
• No apps, no PBX, no VoIP
• A truly professional presence for your business

Most customers who start on VLL eventually choose the Landline SIM once they see how powerful it is but you don’t need to upgrade

🆚 VLL vs Landline SIM — Clear & Simple

⚠️ Why VLL Matters: Avoiding the Divert Trap

We’ve seen too many businesses:

• Start with a basic divert from another provider
• Get funnelled into hosted PBX or app-based systems
• End up in long contracts
• Struggle to switch later due to cumbersome UK porting processes
• Discover the Landline SIM too late

VLL gives you a safe, simple entry point:

• No lock-in
• No complex platform to escape
• No pressure to upgrade
• A clean path to the full Landline SIM when the time is right

🎉 Start Light. Grow Confidently.

ONSIM VLL gives you flexibility from day one:

• Use forwarding
  OR
• Use an inbound-only SIM/eSIM

And when you’re ready, upgrade to the industry-leading Landline SIM that gives your business a true landline identity.

👉 Upgrade to Landline SIM whenever you want
