2G is not at the top of most carriers' list, ATT fully preserves it. My T-Mobile 2G signal is 0 to 2 bars on my phone. For the best connection, use the Pulse Larsen SB698SMA3 small patch antenna. For example, a call forwarding function to check the balance of a SIM card. One improvement is to limit the number of door alarms to a set value. Now it fires every 3 minutes. Also, the guide may be more detailed in separate sections. My green GPS light blinks and sometimes stays on. I would like to know what the difference is. Again a very good product. I wish they released a 4G version so I can use ATT which has the best coverage in my area.
