How to set up MikroTik wAP R with a SIM card from MTS, with a static IP?

Question

MTS

Model MikroTik RBwAPR-2nD&R11e-LTE or MikroTik wAP R with built-in R11e-LTE modem.

I inserted a SIM card from MTS, the Internet for PC + static IP is connected to the SIM card, everything is good.
The LTE interface immediately realized that it had a SIM card in it, received an IP from the provider 100.XXX.XXX.XXX.
Moreover, the IP - DHCP Client is empty, I found the IP in the IP - Addresses tab, automatically received it, I’ll say right away in this model on the latest long-term firmware you can’t throw a DHCP Client on LTE.

The Internet works with a bang, only static does not work. I turned to the great GOOGLE there only about Megafon and Yota.

I understand that few people have such equipment, but maybe someone has at least a link to the info on how to set up a connection from MTS. By the way, for today, the second one has already gone as I am waiting for a response from MTS. At least understand how it works for them in order to try to implement it on their equipment.

Answer 1

Solution found thank you all.
After several calls and sent emails, I was given a phone number where I was told the apn for my region.
For Tyumen apn "statip.ural"

Answer 2

Most often, the operator issues an IP looking at your apn. Apparently you have a default one.
