Hi user!
If you have high permissions but cannot change the configuration, please contact the carrier to obtain the support.
We have Huawei Community support (https://consumer.huawei.com/en/community/list/?forumId=10014), where you can get the answer online and also service hotlines for each country or region. You can get the regional hotline number via https://consumer.huawei.com/en/support/hotline.
Thanks!
