Peace, mercy, and blessings of God be upon you. A 5G router from STC. The device only works with STC SIM cards. The device is very clean. Note (As soon as the SIM card is inserted, the device appears restricted, then after about an hour, the device recognizes the SIM card and works). I give you a 3-day warranty. If there is any issue, it can be returned. My price is 350. Please only serious buyers should bid.
