The extra SIM surf & talk plus option is a flexible solution for connecting multiple devices – smartphones, tablets, laptops, smartwatches – with a single phone number. Up to eight additional SIM cards (physical or eSIM) can be controlled with one main number, without the need for multiple contracts. And the devices can be managed and configured very easily and conveniently with the Sunrise self-management tool.
Example: Imagine a company where employees use one main device and several additional devices, all of which are connected to the same number. When a call comes in, all the devices will ring at the same time. This means that any available employee can take the call, significantly reducing the response time. If multiple calls come in at the same time, teams can process them all in parallel, ensuring smooth customer support.
extra SIM surf & talk plus is the ideal multi-device solution for companies that rely on seamless communication via voice calls, SMS and collaboration apps and whose employees need to be connected on multiple devices. Whether they’re remote employees, sales teams or specialists who travel a lot, this option delivers seamless switching between different devices and increased productivity as a result. It’s perfect for industries like finance, healthcare, retail, logistics and education.
