D-Link DWR-921 LTE (T-mobile) - configuration of incoming connections to the rou

Hello
I have a D-Link DWR-921 LTE router in the branded version of T-mobile.
I have a problem setting incoming connections, e.g. remote access.
DMZ and virtual servers also arranged and still after the current address I can not get "from the world" to the router page.
Someone has an idea how to make it possible to remotely access this router and be able to start some server.

best regards

Mobile operators usually block incoming calls.
And two is the router must have a public IP on the WAN port, and has? what is this IP

Should remote access be used only to manage the router or also as access to e.g. a server in your local network?
What does the ping command show, and what tracert released on the computer where you want to get to the router?
What URL is entered into the browser when trying to connect and what protocol (HTTP / HTTPS)?
Are you sure the router address is correct? Remember about NAT / PAT address translation.

A SIM card is used to connect to the internet, so the wan port is empty, but after the temporary address and changed by ddns no-ip to the name I can not get to either manage the modem or enter the remote server.
As I had a netie it worked and here either t-mobile is blocking something, or this branded router soft is something wrong.

T-Mobile does not offer a public IP address with external access for individual offers, it blocks incoming traffic. You won't do anything about it. Such access can be obtained in Plus / CP or Orange.

Hmm, it's a bit weird, I tested it a moment ago on the Netia card (only for the Internet card) and Plus on the LTE card, and you still can't stick to the router itself.
Is it possible that by default every operator will block incoming calls?

And from what I see t-mobile has something like this on offer.
I just have to check in the contract whether this is internet for business because in total it was bought for the company.
