The GL09 arrived not overly fast but OK. The packaging was good. Unfortunately I did not manage to make it work. I tried 2 different SIM cards (Swisscom and M-Budget) with the same effect: the card's presence is recognized (MCU is blinking slow) but it doesn't register with the network (NET is blinking fast, no SMSs sent to GL09 are received by the unit). Manufacturer's support (e-mail and Skype) just doesn't respond. The seller here on Ali made a couple of obvious remarks but did not really help either. Beware 1: you gonna disable PIN query on your SIM card. Beware 2: this unit is 2G, check with your operator when 2G will be switched off in your country (Swisscom supports until 2020 only).
