The modem is detected and drivers are loaded, I see no Quectel related issue.
From what I can see, EM05 is supported by ModemManager.

Kde/jak nastavujete APN?
Zkousel jste nastartovat network? Napr. pomoci
mbim-network /dev/cdc-wdm0 start

Jinak viz napr. navody na Techshipu (prodejci LTE modulu): https://techship.com/support/faq/how-to-set-up-a-simple-data-connection-over-the-mbim-interface-using-libmbim-and-driver-cdc-mbim-in-linux/

resi si to NetworkManager, ale i kdyz to udelam pres mbim-network, tak je vysledek stejny, tj nastaveny interface a route, ale ping neprojde

dostal jsem odpoved na foru vyrobce modemu:

Unless it is private network, you cannot ping the gateway.
Actually the IP 100.75.215.174 is not a public IP address, it is assigned by the network operator.

a dostal jsem taky odpoved od T-Mobile

neděláme podporu zákaznických modemu,
jedná se o problém modemu že se na segmentu nedopinga na defGW,
pokud to má být interface do mobilní sítě, tak je to špatně.

tak ted fakt nevim: vyrobce tvrdi, ze problem je operator a operator tvrdi, ze problem je v modemu

Nekteri operatori neradi vidi hlasove SIMkarty
v datovych terminalech. (protoze za DATOVE only uctuji vice ...)

Je mozne ze T-Mobile je jeden z nich?

Je ta SIMka vedena jako pro hlasove hovory
a nebo pro datove zarizeni?

Muzete vyzkouset i SIMku jeneho CZ operatora?

ano, je to hlasova SIM-ka

objednal jsem si datovou od O2, tak uvidim jestli to pomuze
