Peace be upon you I have an upgraded ZTE MC801A1 modem that works with all SIM cards and supports 5G frequency aggregation. The device is clean and working at the moment the modem was photographed. The "World of Routers" B7 update has been installed, and it now works with all SIM cards and supports 5G frequency aggregation. This update was installed and the IMEI was changed to my Jawwal number. I have a professional technician, and this change cost 100 SAR. =============== Location: Al-Qassim, Al-Khabara. Hand-to-hand delivery in Al-Qassim.
