I have a Botletics SIM7000 LTE CAT-M1/NB-IoT + GPS Arduino Shield with a Hologram SIM that has just started behaving strangely in the past 8 hours or so. With the Hologram SIM data plan, I have an associated phone number.
Previously, I was able to send SMS to the shield from my mobile device (iPhone 7) using the associated phone number. Then, all of a sudden (earlier today) this capability stopped working. Now, the only way to successfully send an SMS is using some “obscure” +ddddddddddddddd number. This number is not the SIM number of the IMEI number, but appears to be some number generated by Hologram.
Unfortunately, this creates a chicken and egg problem for me. I can’t send a message to the shield without knowing the appropriate contact number, and I can’t get the contact number without receiving an SMS from the shield. (I can work around this for testing, but the work around won’t work for the average person.)
Did something change on the Hologram side? Or am I just simply trying the wrong way
My code is pretty straight forward C, with the Botletics enhanced Adafruit FONA library.
Thanks in advance.
