Thanks for reaching out, and I am sorry to hear of you having network difficulties after an update. This forum is for support of US products and customers. As your product is a non-US model and support for these models is very limited, please seek a support team for your area. You can do so by using this link: https://www.samsung.com/us/common/visitlocationsite.html
In addition, since this has to do with your network, contacting your carrier would be the best recommendation, since they manage your network.
