We have been asked why the SXT LTE and other LTE MikroTik devices wont connect to the cellular network.

MikroTik have a default APN setting that works for many SIM cards however we suggest you put the SIM card in a phone and prove it works.

Once the phone has internet access (via cellular and not Wi-Fi), check the APN in the phone network settings. There will most likely be the following details:

  • Name
  • APN
  • User
  • Password
  • Authentication type

Make a note of all of them.

On the Mikrotik, navigate to interfaces -> LTE ->APN

Add an APN with the details you noted above.

Now click back on the LTE interface, select the new APN and click apply.
Click disable, enable, wait 20 seconds and check internet access.


As an alternative if you like CLI

/interface lte apn
add apn=pp.vodafone.co.uk authentication=pap default-route-distance=1 name=\
“Vodaphone PAYG Internet” password=wap user=wap
add apn=payandgo.o2.co.uk authentication=pap default-route-distance=1 name=”o2 Internet” \
password=password user=payandgo
add apn=everywhere authentication=pap default-route-distance=1 name=Internet password=secure \
