NEC's mobile router, Speed WiFi 5G X12 [NAR03], is SIM-free. While there are concerns about data being extracted from products made in China, this one is from a reliable Japanese manufacturer. This is a valuable, brand-new, unused item. The initial protective film is still attached. It can 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 get 100GB per month for about 2300 yen. 5G is available even at a low cost, making it comfortable to use. The 5G area has expanded considerably in the past year, which is very good. I will gladly provide information to those who are interested. Also, if you are unsure about APN settings, I will provide careful support. There is also a manual. I will include it if you wish. The box will not be shipped due to shipping via Nekopos, but I will ship it folded if you wish. A new dedicated case is included. The inside is made of 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. Achieves a maximum download speed of 3.9Gbps. Supports SA 5G, the first for a WiMAX mobile router. Security: Supports the latest Wi-Fi security standard WPA3, enabling stronger security measures. Convenience: Lightweight and compact design for easy portability. Equipped with a 4000mAh battery for long hours of continuous communication. Supports Wi-Fi connection settings via QR code. By using a separately sold dedicated cradle, wired connection and more stable 5G communication are possible. Other: You can easily manage the device and check data usage with the dedicated smartphone app.
