NEC mobile router Speed WiFi 5G X12 [NAR03] SIM-free. Made in China can be a concern due to the possibility of data being extracted, but this is a reliable Japanese manufacturer. It's in beautiful condition, having been used only for a short time. Operation has been confirmed. In the used market, many have scratches on the corners, but I think this is in excellent condition. There are only a few minor scratches on the surface, so I'm offering it at a bargain price for this one item. I also checked the battery life, and it hasn't changed from when it was new. I think it has plenty of battery life. This condition is valuable, as many have deteriorated batteries due to being constantly connected to a cradle. It can also be used with Rakuten Mobile, allowing you to have unlimited Wi-Fi for a low price. I use the same model with a Rakuten Mobile prepaid SIM and use 100GB per month for about 2300 yen. You can enjoy 5G even at a low price, so it's comfortable. The 5G area has expanded considerably in the past year, so it's very good. I'll be happy to share more information if you'd like. Also, if you have any concerns about APN settings, I will provide careful support. There is also a manual. I will include it if you wish. It will be shipped via Nekopos, so the box will not be shipped, but it can be shipped folded. A new dedicated case is included. The inside is microfiber, so it stays clean just by being in the case. No price reduction is possible. The main features of Speed Wi-Fi 5G X12 [NAR03] are as follows: High-speed communication: Supports 5G and Wi-Fi 6, enabling fast and stable wireless communication.
