Frequently asked questions
Why does my phone look different from the guide?
Your administrator chooses which buttons and features are turned on, so layouts can differ.
Do the star codes work on every system?
No. Codes such as *72 for forwarding depends on your phone service provider. Ask your support team to confirm the ones you can use.
How do I clean the phone?
Use a soft, dry cloth only. Liquids and sprays can damage it.
Can I call emergency services from the phone?
Yes. Dial the emergency number normally. Your location and callback number are sent, so make sure your administrator has set your location correctly.
What do I do if I change my voicemail PIN?
Change the default PIN the first time you log in, so nobody else can listen to your messages.
Need help?
Contact SB Link Network support for setup, new features or any problem you cannot fix. Have your phone model and MAC address ready (Applications, then Phone information).
