GSM desk phones vs. VoIP phones What's next? Expand What is a GSM desk phone?GSM desk phones differ from regular desk phones in that they hook up to the mobile network, rather than the landline network. They’re almost like a large mobile phone (but not quite the brick from the Seventies).GSM (global system for mobile communications) refers to the mobile connection being used. And like a mobile phone, GSM desk phones use a SIM card to make calls, rather than connect to your office building’s internal telephone network. This makes them incredibly easy to set up and move – you can literally just plug in and go.Depending on the SIM card you use, the GSM connection can be 2G, 3G, or 4G. As we already know, the higher the number, the speedier the connection. These days, the majority of GSM desk phones operate with a 3G or 4G SIM, in order to keep up with modern day business demands.In some ways, GSM desk phones are similar to VoIP phones – for starters, they’re both hosted by a third party provider. The difference is GSM phones don’t tend to offer businesses the same level of functionality as VoIP phones, but often cost just as much per month to operate. We’ve dedicated a whole paragraph to VoIP vs GSM later on in the article.GSM desk phones use a mobile connection, rather than a landline connection, to make calls Save by comparing phone system prices from the best providers for you Do you already have a business phone system?
