The 3G mobile network is outdated. We recommend switching to a 5G-capable mobile phone. As a general rule and whenever possible, it’s good to opt for the latest generation of devices and to install the latest device software (iOS, Android, etc.).
The fifth generation of mobile communications offers plenty of advantages: significantly higher upload and download speeds, low latency and much more. At Sunrise Business, we’ve got a range of offers available for you: 5G-compatible devices and the perfect mobile subscriptions.
Is 5G perhaps already available on your device, but you’ve somehow deactivated it? Maybe even on purpose, to save battery life? Check your phone settings. We recommend that you select «5G automatically» for lightning-fast Internet.
VoLTE stands for Voice over LTE and allows you to make calls via the 4G/LTE mobile network. We’ve noticed that many of our customers have deactivated this function on their 4G devices. Activate VoLTE and benefit from crystal-clear sound quality, fast connection and a significantly reduced dropped-call rate.
You’ve got a 4G mobile phone and are struggling to make calls abroad? Then be sure to activate VoLTE when you’re abroad. But it’s best to make calls via Wi-Fi in countries where VoLTE isn’t available.
If your mobile network quality inside a building isn’t great, we first recommend activating the «Wi-Fi Calling» option. If no Wi-Fi is available, our Business Indoor Coverage solutions are a great option.
If the mobile phone cells are overloaded, the transmission may be interrupted when using video- and audio-calling apps such as WhatsApp, Microsoft Teams, etc. For a better connection, we recommend using the Sunrise services VoLTE or Wi-Fi Calling.
To get the best reception, we recommend using the excellent Sunrise network together with high-performance devices.
Are you looking to upgrade individual devices or planning on renewing your entire device fleet? We can offer you the perfect solution for any situation.
