Has anyone actually gotten these SIM7000 with the Hologram sim card on an ATT network (or any network for that matter) to actually work right? I got the SIM7000A board, hologram SIM card, a number signed to the SIM card, and was able to load the LTE demo. Everything worked, ATT network, gps etc except I'm not able to get SMS from the 7000. I can active the send command, type in my number to send the sms too, type in the sms, and it says it sent successful, hologram charges me the .19 cents. But the message never comes through on any of the 3 phones I've tried that are on the ATT network as well. The arduino does receive messages sent to it. Any suggestions before I trash this entire thing and get something commercial?

Is your phone blocking hologram's number as spam or something?

No. The phones don't seem to have the number blocked.

And you're typing a "1" (country code) in front of the phone number you're sending to?

I think it's a Hologram issue because it definitely worked before. I just tested mine and it says "Sent!", but on the Hologram dashboard it doesn't show any SMS was sent out or any data was used. But when I send an SMS to the device from the Hologram dashboard, it gets it instantly... I'll contact Hologram and see what's going on.

Yes I tried typing a 1 in front of my number. I am wondering if ATT has changed as well. Seems like you are having the same issue now I also saw using mine. I also got a call into hologram and will report back if I hear anything from them. Going to pursue ATT a bit more as well, Im wondering if they changed their plans to now not recieve out of country texts. Thank you for your help so far on this!

I figured it out! You have to put your country code in front of the number you are dialing. Since hologram outgoing numbers come from United Arab Emirates(882 prefix as documented on their website) ... You have to prefix your phone number you are dialing here in the US with 00. For example to send SMS to my phone...I have to have my arduino dial 001231xxxx. 00 being the USA country code FROM UAE... The 1 for us long distance calling... The 231 in my example as my area code.. Then the last 4 digits. So the firmware for dialing a number in the US is 0001xxxxxxx Hope this helps someone else.

Super helpful, thanks! That did it for me too. Strange that "1" used to work before, but "001" comes through instantly!

I will soon be a newbie to the Botletics SIM7000A LTE CAT-M1 NB-IoT Shield if I can first be satisfied that I will be able to programmatically send and receive LTE text messages via both T-Mobile and ATT. I have not yet found an example of either. Where can I download working examples? I plan to use the SIM7000A to replace my MKR GSM 1400 (2G/3G). I tried the MKE NB 1500 (LTE) and it is useless. The Firmware and/or Library has known and unresolved issues as of this date 2023.09.17. After being burned by many wasted hours on the 1500 I want to be reasonably assured I will have success with the SIM7000A before purchasing.
Thanks in advance for your help.

It'll at least work on AT&T with LTE CAT-M in the US. T-Mobile should also work. Examples are all on GitHub, tried and tested. |
