I used this for about two months when I first bought it. After that, I bought another device, so I stored it without using it. I am selling it to organize my belongings. The Aterm MP01LN is a mobile router with a built-in battery and USB connectivity. What looks like a scratch on the screen is actually the screen protector, which has not been peeled off. - Rechargeable - SIM-free - Dual SIM - Brand: Aterm - Included items: USB cable, main unit - Model: NEC Aterm MP04LN - Battery: Built-in lithium-ion battery - Power: 5V 1.5A Thank you for looking.
