Which SIM card do I use?
For SME’s.
If you require a landline number for your business, you can speak to your local mobile network operator who will provide you with a business SIM card that has both a landline number and mobile number connected to it. BT in the UK and Vodafone in the UK and Europe offers this service.
For SOHO’s & Private.
If you’re a private home user or a small office, you can use any network SIM card in a Tecdesk device. The number shown will be the mobile number of the SIM card.
