For sale: Zain router, National Day edition, with a Huawei network booster. All devices come with their original boxes. Selling to the highest bidder. Location: Tuwaiq district. Contact via WhatsApp or private messages. **Regarding the router, I am using a Zain SIM card on it, so I don't know if it works with all networks or not.** I think you need to unblock it from the main Zain and Mobily branch and insert your own SIM card.
