What is a mobile landline SIM?

"A MOBILE SIM WITH A UK LANDLINE NUMBER"

section-02055b7

A mobile landline SIM (such as our ONSIM Landline SIM) is a SIM (Subscriber Identity Module) card that can have a UK landline number (starting 01, 02, 03 or 08) as well as a UK mobile number (starting 07). This offers a choice of number that is displayed to the callee on an outbound call. Mobile landline SIM’s are typically used by businesses who want to present a professional image to their customers but where it’s not feasible or desirable to install a traditional fixed/cable landline. Other (but not all reasons) someone would choose to use a mobile landline SIM are;

  • Mobile Working - being able to answer and make calls from your landline on the move

  • Cost Savings (for both the owner and those calling the landline)

  • Separation of business and personal numbers for privacy

  • Monitoring usage / staff

  • Scalability - multiple users can share the same number

  • Redundancy for other phone solutions

  • Where internet speeds aren’t stable enough for VoIP (Voice Over IP)

  • Time sensitive setup - no installation means they can be set up instantly

  • Compliance requirements

Because of their deep integration into our unique cloud based mobile PBX (MPBX) mobile landline SIM’s also have a wide range of other features normally only found on traditional office phone systems such as call recording, hold and transfer, group features and more. These converged services allow greater flexibility and mobility of existing workforces giving businesses “The best bits from your regular office phones but with the freedom of a mobile”.

How do mobile landline SIM’s compare to other solutions?

There are lots of providers in the UK that claim to offer ‘mobile landlines’ or 'virtual landlines'. These fall into one of two categories; ‘Diverts' and ‘Apps'.  As you can see below, neither solution truly offers the simplicity or power that you get with a mobile landline SIM.

section-a61c9e7

Landline Diverts / Virtual Landlines

This solution involves a phone provider supplying a virtual or hosted landline number that is on a permanent divert to a mobile number of your choice. There are a couple of issues with this approach:

  • The divert is always chargeable, meaning that you will be either capped to a certain number of inbound minutes per month or you will pay by the minute to answer your calls. What happens when you run out of inbound minutes? Blocked calls and extra charges.

  • If you are using a personal mobile it might also be hard to distinguish between business and personal calls leading to confusion, missed calls and embarrassing situations.

  • Voicemail can also be a big issue with virtual landlines and diverts as often a personal voicemail kicks in before the system voicemail giving away to your caller that this call is on divert.

  • Possibly the biggest issue with virtual landlines is what if you miss the call and want to return it? If you call back from your mobile the caller has your personal mobile and won’t call your landline again. If you call back and withhold your number they might not recognise or answer it (lots of customers we survey tell us they do not answer withheld numbers). Some customers might consider this to be unprofessional and cast doubts around the size and legitimacy of your organisation - there is a real stigma around mobile and landline numbers in the UK.

  • Another question to consider is "What if you aren’t the only one that answers calls?” If you need a group of people to share the burden of answering calls virtual landlines often won’t scale very well past one or two users.

Although there are some drawbacks of using a virtual landline forwarded to your mobile, they are often a good start for a company phone line. If you already have a virtual landline or are looking for something a bit more feature rich, why not take a look at our Landline SIM.

landline app

Mobile Landline Soft-phone Apps

Essentially these solutions are 'soft-phone’ (software phone) apps installed on a smartphone that connect over a data connection to a VoIP system and allow you to make and receive calls. This solution is touted as the future of unified communications and it sounds great. Unfortunately, in the real world WiFi and Data networks simply don’t provide a consistent enough connection for high quality calls. Buffering and dropped calls will make you sound like you’re underwater and frustrate both you and your customers and within a short time you will give up on it. Furthermore, you can only make and receive the calls when you have the app on or on background refresh which will deplete your mobile phone battery very quickly.

Although there are some drawbacks to using mobile apps, largely due to current mobile data limitations, they work ok alongside our mobile landline SIM’s. Our customers often use soft phone apps to cost effectively make and receive calls on their landline when they are outside the EU or for remote workers.
