I purchased a DIGI LTE-M module and subscribed to a AT&T data plan. I can connect and get a reply from the echo server. I can not send SMS text messages. AT&T says their IoT data plan does not support SMS Text messages. I get an error message. Anyone else had this experience? All I want to do is be able to send a SMS Text from my device to a cell phone. Would a DIGI LTE device work with an AT&T LTE North America data plan work? I would be curious if anyone has gotten the SMS example code to work with a LTE-M module with any service plan. Any help would be appreciated. ---

Hi, I have a normal AT&T Cat-1 data plan and I am able to send a text no problem using the documented MicroPython, API Mode, and Transparent mode methods. It sounds like you will need a different data plan to meet your requirements. ---

Which module and cellular plan are you using, I believe that’s pretty important in the what works/what doesn’t conversation. A SimCom Sim7000A cellular module (not XBee… I still don’t really know what XBee is) works with [Hologram.io](http://Hologram.io)’s plan, but each SMS costs 19 cents. Botletics makes an arduino shield for the SIM7000A and there are some low cost breakout boards available as well. And C++ libraries which make the SIM7000A easier to work with. @DigiFan23 - is it the Trio data plan? I’m looking at [https://marketplace.att.com/products/att-iot-dataplans-lte-m-us](https://marketplace.att.com/products/att-iot-dataplans-lte-m-us) which says nothing about SMS. Thanks- ---

I corrected my mistake. The SIM I use it technically a Cat-1 capable SIM. ---

Cool, do you know what brand / model SIM it is? ---

It is a private MVNO that uses the AT&T network. ---
