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?
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.
