Question about Netgear AirCard 810

1. it needs a "Micro" size SIM card. I strongly advise against using a mini SIM card together with an adapter. Reason: The slot is very narrow. You can get the combination (mini SIM + adapter) into the device, but when you slide it out later, the contact feet can break off... (unfortunately this happened to me once - then you can scrap the part).

2) Yes, a (rather clumsy) USB power supply is included in the delivery. It works with 100 volts to max. 240 volts, and adapters for other countries are included. But you could also use your own (strong) USB charger - weak chargers don't work. A (rather short) USB charging cable is included that connects to the AirCard with USB 3.0 Micro-B (this connector is much wider than the usual USB charging cables for smartphones).
