Milesight Routers and Gateways: SIM Setup Guide

Milesight makes compact UR industrial routers and UG LoRaWAN gateways that send their sensors' data over 4G. A ThingSIM gives each gateway its uplink on whichever Irish network reaches the site, from a city building to a farm in the West.

How to set it up See the 16 models

Setting up a ThingSIM in the Milesight router and gateway web interface

The APN goes in Network → Interface → Cellular. Copy it from the SIM's page in the ThingSIM portal; there is no username or password.

  1. Activate the SIM in the ThingSIM portal, then insert it in SIM1 before powering on, with all cellular antennas connected.
  2. Go to Network → Interface → Cellular (on UG gateways, Cellular Setting).
  3. Edit SIM1. In SIM-APN switch Auto APN off, enter the APN from the portal and set Authentication Type to None.
  4. In SIM Setting turn Roaming on. A ThingSIM always connects as a roaming SIM and will not register without it.
  5. Click Save, then Apply.
  6. On routers, enable the cellular interface under Network → Interface → Link Failover.
  7. Status → Cellular should show Connected.

Two SIMs for failover

Two-SIM routers use one SIM at a time. Priority is set in Network → Interface → Link Failover, and each SIM can switch on data limit, dial failure or ping failure. UG gateways take one SIM.

Checking it works

Status → Cellular shows the current SIM, network, signal quality and monthly data usage.

Questions people ask

How much data does a Milesight LoRaWAN gateway use?

Sensor traffic is small; most gateways fit in 250 MB a month, €1.29 on Ireland multi-network. Check usage in the portal after the first month.

Does a ThingSIM work in a Milesight UR32?

Yes. Insert the SIM, set the APN from the portal in the cellular settings and the router connects on the strongest of Vodafone, Three and eir.
