Hi!

By mistake, I bought five RUT240 instead of five TRB140. crying sad

I need the devices exclusively for sending status SMS.
How can I configure the RUT240 so that neither WiFi nor mobile data are used?
The communication must run exclusively in this direction:

Server ==http==> [LAN] RUT240 ==SMS==> Mobile phone

How can I disable mobile data completely and allow only SMS sending?

Thank you very much!

Hello,

I would like to suggest navigating Network > WAN and leave mobile and WiFi unchecked at all. By doing that your SIM card will not use any data, but you should be able to send SMS messages.

Regards.
