Zain 5G modem with Zain Internet SIM card, old open system that is 171 per month

The modem comes with an internet SIM card, open usage. I have used the modem for a year and am selling it along with the SIM card. It supports 5G, has no issues, but my large signal was transferred; it doesn't support 5G anymore. The internet renewal was 171 monthly. Selling the modem and SIM card together
