How does mobile radio work?

• You can make calls using your cell phone or smartphone and the appropriate SIM card.
• Your smartphone searches for the next available cellular signal to set up the call.
• The better the signal, the better the quality of the call.
• Especially in rural areas or in tunnels, there may be no mobile phone signal available.
• In this case you cannot make phone calls; only the emergency call works.
• Your call partner's cell phone must be switched on for the call to work.
• In addition, it must also have a sufficient mobile signal.
• Tip: You can read the network coverage of your provider in our network test chip.
