Difference between globallink 520 and GX LTE 4G

I'm using a cerbo GX and I'm looking at a way to connect my system to the cellular network.

In the description of the globallink 520 it says that it comes with a 5 year sim-card.

1. Does the GX LTE 4G come with a similar 5 year sim-card?

Or since the globallink 520 is about the same price as the GX LTE 4G.

2. Can u use the globallink 520 with the Cerbo GX?

Thank you guys in advance for the help!

Cerbo GX and 4G-LTE settings


I have the Cerbo GX with the optional LTE-4G-Modem. The APN settings in the Modem settings only allows you to type in the APN name, but NOT the username and password.

I purchased an inexpensive prepaid SIM card for 365 days with 20GB of data. But I just can’t get the GX-LTE-4G modem to go online. The SIM card works fine on my iPhone if I type in the complete APN information. So I’m assuming it’s something to do with the APN. The unit detects 3 bars of the Antenna signal and the Carrier service, but the internet continues to be “offline”.

Any reason why it doesn’t let you type in the complete APN settings?

GX-LTE-4G-E in Japan?


Does the LTE-4G-e modem work in Japan?

Purchased a prepaid SIM card but can’t get it to work. The APN settings page only allows you to type in the name, but no username and password that you can type in.

I tried the SIM card on my iPhone and I’m able to connect to the LTE network, so it looks like the SIM itself is working.

Data use for GX LTE 4G

Anyone know what the data use is for the data use for GX LTE 4G. Some telco's have IOT SIM plans which are cheaper than a normal data SIM. But the data limits are small.

Victron GX LTE as a failover

Does anyone here uses Victron GX LTE as a failover for their GX device? I'd like my Cerbo to use my wifi router by default and automatically switch to GX LTE when I switch off the router to save energy. According to manual the Cerbo does automatically switch between Ethernet and WIFI, but no mention of LTE https://www.victronenergy.com/media/pg/Cerbo_GX/en/internet-connectivity.html#UUID-3d87b06d-37ea-8e8c-64e2-3723b602fe88

GX LTE 4G: SIM not inserted, but it is.


I have bought a GX LTE 4G module and have inserted a sim card. But it keeps telling me that there is no sim inserted. It doesn't recognise the sim card but when I insert it into my phone it works fine.

It is a normal mobile sim (data and phone) that is inserted into the module. Do I need an only data sim card? Will this fix my problem?

It is inserted into a Multiplus II GX and is running firmware v2.84
Thank you in advance!

GX LTE 4G-A not transmitting to VRM

Hello everyone,

I am having an issue with the GX LTE-A transmitting data to VRM. I have a T-Mobile unlimited data SIM card. The GX LTE shows that it is connected to the T-Mobile network. Internet-Online, Sim status-Ready. I have also manually entered the APN (fast.t-mobile.com).

When I look at VRM online portal I see error #159.

If I turn off Use Secure Connection (HTTPS) I get error #150

Please see photos for reference.

Any help on the matter would be greatly apricated.

Can the GX LTE 4G-A use an AT&T LTE-M SIM? Or will they be making one?

I looked at the GlobalLink but it doesn't have enough VE direct ports to replace my CerboGX. With AT&T selling $30 a year unlimited data M1 plans, keeping VRM updated with less of an monthly outflow of cash would be a great thing and they work pretty much everywhere in the US, Canada & Mexico. Of course, if they made one specifically for that (low power) that would be better. The GL just falls very short on the capabilities and cannot really replace a Cerbo. -Bill

I have a rather large Victron System that was recently commissioned and all was great. We added a GSM 4G-LTE and everything went haywire in regards to the MFD Integration. If the GSM is unplugged the APP on the SIMRAD MFD works great. And if the SIMRAD is unplugged the GSM works great and will work as intended. WIth Both plugged into the CERBO the APP stops working on the MFD and we lose INTERNET DATA and connection to the VRM. Sometimes the MFD will pop up a screen saying to "Make sure MQTT Plaintext is on", which it is. I have a feeling this has to do with SIMRADS DHCP server in their system and addressing conflicts, but I am not sure. Have you ever had this issue before? What can I do to remedy this?

Cerbo GX Error 153 on 4G

Good time of day!

I have an issue with Cerbo GX connecting to the VRM server over 4G. WiFi works fine, however when I switch over to 4G using the Victron modem it cuts out. It throws Error 153 (more detail on image).


SIM card is definitely working, tried 3 different ones including one I normally use on my phone.

What should I do to get it working?

Thanks in advance!

Which GX device would you recommend? And LTE 4G, or router?


I've tried reading up on the different GX devices, but I don't have the full overview. I'd like some input in regards to what others would choose.

My needs, in prioritized order, is to remotely:

- Open a relay to start the generator. This is an old yanmar diesel with a starter engine, so the relay needs to be open for a few seconds to connect the starter battery with the starter engine, and then the relay needs to close again.

- Turn on and off the inverter part of the Multiplus

- Turn on and off the charger part of the Multiplus

- Any BMS functionality is an added bonus, but not strictly needed

Which GX would you choose?

I don't have wifi with the system yet, so the next question is:

would you choose a victron LTE 4G to remotely operate this, or a standard 12v router?
