I am trying to determine if any Teltonika routers/gateways can send and receive SMS messages over 4G. I need to verify 4G SMS before I purchase a Teltonika device.
I have looked through the user manuals for several routers/gateways that support SMS. The device user manual’s state that the device must be connected to a GSM network for sending SMS messages. Is this correct, or is that claim outdated?
Is anyone using a Teltonika device to send and receive SMS messages over 4G?
Obviously the device must be connected to a GSM network, how else should it be able to send/receive?
I’ve owned a RUT950 for several years and now have a RTX50 that both work perfectly well with SMS.
4G supports SMS over IMS or NAS, GSM is not available. By GSM network, does Teltonika mean a 2G or 3G network, or does it mean a network that supports the GSM message format? 4G does use the GSM message format.
I have seen some questions on this forum asking for help on sending SMS over 4G, and some advice given. It is not clear if the advice worked or not.
Hi,
Yes, most of the devices support SMS over IMS or NAS. I’m saying some, as certain LTE modules are data-only. Could you clarify what device in particular you’re interested in?
I need to use the device with AT&T in the United States. I am looking at AT&T’s list of certified devices at https://iotdevices.att.com/certified-devices.aspx
RUT240AF
RUT956AF
RUTM50
