You can identify that the Super-G has no connection when you see crossed out SIM icon on the watch screen. In this case, make sure that:
- SIM card inserted properly. (How do I insert a SIM card?);
- The SIM card was inserted into the device when it was switched off (if it was on – restart the watch);
- PIN code protection on the SIM card is disabled;
- SIM card is activated (for example prepaid SIM cards).
