RUT240 won't connect to mobile network

Teltonika Networks

Hi,
I have a new RUT240 router, bought from digi-key in the US. I am in Denmark, attempting to use the router, but it does not seem to be able to connect to any mobile networks. I have tried 2 sim cards, with identical results.

The modem doesn’t appear to be able to find a network at all. When I do a scan for network operators, for instance, i get no results (empty list). I am in a city, with excellent network reception on my phone with the same sim cards.

I’ve tried everything I can think of (trying different Sim card setting, APN settings etc), but the modem simply never sees a network, whatever I do. The web UI never actually reports an error (problem with sim card etc) it just never seems to see a network.

In case anyone can help me - here’s the start of the “GSM.log” file in the troubleshooting info :

For anyone else having this same problem - I think I discovered the cause.
The model of router I got only works in the US, and doesn’t seem to work anywhere else in the world. You need to very carefully check the model number before ordering, because different models cover different network bands and work in different places. Very confusing.

I may have the same issue with 12 RUT955s purchased in the USA and used in the UK how can I tell if this RUT955 will work in the UK

Cheers John

Hello,

@Jbaggott

You can check the product code of you device to see if it can be used in your region. You can find this information on the RUT955 product page here in the Ordering -> Available versions section.

Kind Regards,
