The Teltonika RUT240 and RUT241 are compact 4G LTE routers with built-in Wi-Fi and GPS. This guide covers hardware setup, the manual APN configuration, an equivalent configuration script, and a few optional features worth turning on: remote access, PING reboot, and SMS reboot.

Before you start, make sure your SIM is activated in the Simbase dashboard. If it isn't, see Enable or disable a SIM card first.

For a visual walkthrough alongside this guide, see Teltonika's RUT240 setup video.

Step 1: Prepare the hardware

1. Press the SIM holder release with the included needle and remove the SIM tray.

2. Insert your Simbase SIM into the tray and slide it back into the router.

3. Screw the antennas onto their connection points. Match the Wi-Fi antenna to the Wi-Fi connector and the mobile antenna to the mobile connector.

4. Connect the power cable to the router and plug it into an outlet.

Step 2: Connect and log in

The router takes a few minutes after power-on for its Wi-Fi network to appear. The Wi-Fi name (SSID) and password are printed on the bottom of the device.

1. Connect your computer to the router's Wi-Fi.

2. Open a browser and go to 192.168.1.1.

3. Log in with username admin and password admin01.

4. If this is your first login, you'll be prompted to change the default password, follow the prompts.

5. Click MODE in the top right corner and switch to advanced mode. The remaining steps assume advanced mode is on.

Step 3: Set the APN manually

1. Go to Network → Interfaces.

2. Click the pencil icon on the MOB1S1A1 entry.

3. Turn off Auto APN.

4. Leave everything else at its default, except:

   • APN: --custom--

   • Custom APN: simbase

5. Scroll down and click Save & Apply.

Your SIM should now connect to the internet.

For background on what an APN does and how Simbase's APN profiles work, see Set up the APN.

Step 4: Or configure everything via script

If you'd rather paste a script than click through the UI, this does the same APN setup plus a set of recommended and optional extras, including renaming the router's Wi-Fi network.

1. Log in to the router and go to System → Custom Script.

2. Clear the input field.

3. Paste the script below and click Save & Apply.

# Set APN to Simbase (required)
uci set network.mob1s1a1.disabled='0'
uci set network.mob1s1a1.force_link='0'
uci set network.mob1s1a1.stp='0'
uci set network.mob1s1a1.igmp_snooping='0'
uci set network.mob1s1a1.method='nat'
uci set network.mob1s1a1.pdptype='ip'
uci set network.mob1s1a1.force_apn='-1'
uci set network.mob1s1a1.apn='simbase'
uci set network.mob1s1a1.auth='none'
uci set simcard.@sim[0].auto_apn='0'
​
# Set router config to Advanced mode (highly recommended)
uci set vuci.main.advanced='1'
​
# Set WiFi name to Simbase and set password to simb4se (optional)
uci set wireless.default_radio0.ssid='Simbase'
uci set wireless.default_radio0.key='simb4se'
​
# Disable Wifi entirely (optional, but recommended when not used)
uci set wireless.default_radio0.disabled='1'
​
# Enable remote HTTP (optional)
uci set firewall.@rule[11].enabled='1'
​
# Enable remote SSH (optional)
uci set firewall.@rule[10].enabled='1'
​
# Enable SMS reboot (optional)
uci set sms_utils.@rule[0].status_sms='0'
uci set sms_utils.@rule[0].authorization='no'
​
# Change LAN IP and subnet (optional)
uci set network.lan.ipaddr='192.168.1.1'
uci set network.lan.netmask='255.255.255.0'
uci set network.lan.proto='static'
​
# Enable PING reboot (highly recommended)
uci set ping_reboot.@ping_reboot[0].enable='1'
​
# Save all settings (required)
uci commit && reload_config
​
exit 0

The # (required), # (highly recommended), and # (optional) comments mark which blocks you can safely remove if you don't want that behaviour. The required block is the first one, it's what sets the APN to simbase. Note the final uci commit && reload_config saves everything, including any optional blocks you've kept.

For a guided version of this step, please see below :

Enable remote access

Teltonika routers support remote configuration, useful if you need to reach the device's admin panel without being on its local network. For step by step guidance, please see below:

Enable PING reboot

We strongly recommend enabling PING reboot. Once enabled, the router pings Google's DNS (8.8.8.8) every 5 minutes. If a ping fails, the router assumes there's a mobile connection problem and reboots itself, recovering from silent drops without anyone needing to notice or intervene.

For step by step instructions, check out the tutorial below:

Enable SMS reboot

If the router ever loses its data connection entirely (so it can't be reached over the internet), SMS reboot gives you a way to force a hardware reboot remotely. See Teltonika's SMS reboot walkthrough to enable it.

Once enabled, send an SMS containing the text reboot to the device's number to trigger a reboot. For how to send SMS from Simbase, see SMS.
