What is a landline SIM?
A landline SIM is like a regular mobile SIM card from other mobile networks but with a landline number (01,02,03,08,etc) instead of a mobile number (07). When you dial out the person you call will see your landline number not a mobile number and when someone calls you on your landline number it rings straight through to you - it's not a divert or trick, there are no apps to install it works just like a regular mobile SIM.
Can I have a landline and a mobile number?
Yes – 2 numbers, 1 phone!
You can use your mobile phone to answer calls on your existing landline number and your mobile number, without needing a second phone. Giving you the flexibility of a mobile with the professionalism of a landline number—no need to carry multiple devices.
Can I use an existing landline or mobile number?
Yes – you can transfer (port) your current landline or mobile number to our service. This way, your customers can keep calling the same number they already trust, but you’ll have the flexibility to take those calls wherever you are.
What number is displayed to the person I'm calling?
You can set the caller ID to any number you own. Landline or Mobile.
How would using a landline SIM benefit me/my company?
Stay professional: Use a trusted landline number on your mobile.
Never miss a call: Answer landline calls anywhere you are.
Work smarter: Transfer or forward calls with ease.
Save money: Combine landline and mobile in one device.
Keep your number: No disruption for your customers.
"More calls answered = more jobs won."
Are there any other features?
Yes. Loads! We can provide everything you would need from a traditional office phone service but without the high cost and poor quality – our support team are on hand to talk you through the solutions we can provide and answer any questions you may have.
Is this VoIP?
No – VoIP uses the internet to make and receive calls, which means you need a reliable internet connection. ONSIM uses mobile networks, so calls come through just like on your mobile. No internet, apps or Wi-Fi required.
