How to enable Internet on MikroTik SXT 4G kit?

Question

Mikrotik

I bought a MikroTik SXT 4G kit (RBSXTR & R11e-4G) I inserted a
SIM card, connected it via PoE, plugged an ethernet cable into the computer
(I tried Tele2, MTS, Beeline cards in turn, the result is the same) I
installed APN in the web interface (for tele2 intenet.tele2. ru, for MTS internet.mts.ru, for Beeline internet.beeline.ru)
The interface shows a normal signal (I'm testing in the city for a start ) computer from Mikrotik itself (tried addresses 8.8.8.8 and 1.1.1.1) The only thing when it passes (responses come) is if pinging on Mikrotik with the ARP Ping DNS option does not work the same way. What to do?


Maybe the problem is in the tariffs, and the SIM with the tariffs for the smartphone is blocked by the operator when it is inserted into the modem?
But I checked with three operators, one of them must pass at least some traffic ...

The SIM cards themselves, when inserted into the phone, work fine, more than 10 Mbps according to Speedtest ...

UPDATE: everything was decided by resetting the settings. After that, everything worked, ping, DNS, and everything else.
It looks like it was sold with some settings that prevent it from working

Well, if Mikrotik is configured correctly and there is a masquarade rule for the WAN interface in the firewall, then the problem is in the SIM card tariff.
Mikrotik is not just a sim inserted and flew, it still needs to be configured
. Ask this question to Google. There are a lot of manuals

Ping not Google, but your uplink. If the ping goes to the uplink, then deal with the sim card.
