Peace be upon you. I have this router, used for only a few days. Device model: ZTE MC888A ULTR STC. The device works with all SIM cards. You can see the device's features on Google. Its basic features: Wi-Fi broadcast for long distances up to 100 meters. High connection speed for 5G and 4G networks. Suitable for institutions and companies because it can handle 256 users without speed reduction. Possibility to connect an external antenna. In short, the device is intended for large establishments and large homes. The device is guaranteed and for sale to the highest bidder. Contact me on WhatsApp due to my infrequent visits to the site. My location: Hay Munfuha Al Jadidah.
