Rakuten mobile router, equipped with a color LCD display and built-in battery, making it convenient to carry. Standard SIM, nanoSIM, and microSIM cards can be used. - Brand: Rakuten Mobile - Model Name: WiFi Pocket R310 - Accessories: Charger and USB cable (non-genuine), SIM card size adapter (SIM card not included) - Display: Color LCD It was only powered on a few times when purchased, and I have been using a SIM card on my smartphone since then. Therefore, this device has not been used much, and I have not taken it outside. There are no noticeable scratches, but please consider it as a used item. I confirmed that it communicates normally with a Rakuten Mobile SIM card when listing it. It seems that other company's SIM cards can also be used by changing the APN settings.
