A:Answer No SIM card, that's what your wireless provider gives you to connect to their service. You can connect with any device that has a Wifi option, so any brand phone, tablet or computer will work. You just turn on Wifi, push the wifi button on the printer and then select the printer on your device. Once connected, you go to the photo, choose print on your device, and choose that printer. You can also password protect it.
You can also insert an SD card. (We use a micro SD with adapter. ) No phone app required.
