Customer types


A mobile network operator or MNO is a provider of wireless communications services that owns or controls all the elements necessary to sell and deliver services to an end user. In addition to obtaining revenue by offering retail services under its own brand, an MNO may also sell access to network services at wholesale rates to mobile virtual network operators or MVNO's.


A Mobile Virtual Network Enabler (or MVNE) is a company that provides services to mobile virtual network operators (MVNO), such as billing, network element provisioning, administration, operations, support of business support systems and operations support systems, and provision of back end network elements, to enable provision of mobile network services.

Solution Provider

A Solution Provider is a vendor, service provider or value-added reseller that offers any combination of hardware, software or consulting services through a third party channel. For selected services Comfone cooperates with Value-Added-Resellers and other 3rd parties such as Telco equipment vendors, global carriers and messaging providers that comprehensively handle their clients overall project needs from concept to implementation.


A wireless Internet service provider (WISP) is an Internet service provider (ISP) that allows subscribers to connect to a server at designated hot spots (access points) using a wireless connection such as Wi-Fi. This type of ISP offers broadband service and allows subscriber computers, called stations, to access the Internet and the Web from anywhere within the zone of coverage provided by the server antenna. This is usually a region with a radius of several kilometers.

We have worked with the Key2roam Roaming Hub for several years. It is been a welcome complement to direct relationships for us, allowing swift launches and extra coverage that would have been difficult to achieve in-house. I particularly appreciate the hassle-free testing procedures, and the overall safe and carefree feeling provided by the service.

Kudos to the Key2roam hubbing team – always helpful and efficient, and consistently topping that off with friendliness. It is one thing to make it work – it’s another to make it a pleasure for customers.

With these few words, I want to express all my gratitude to the whole Comfone team, and especially to Ms Katherine Buschang who has always been there where I needed her support.
You are great colleagues and I am really happy to work with people like you.
If my words count for some, I will recommend you on a large scale.
