We purchased a phone number for our Hologram SIM, thinking we should be able to use it like other SIMs we have obtained from other carriers/MVNOs, but it doesn’t seem to be working. For what it is worth, we are using the Hologram SIM in a MultiTech MTSMC-LAT3 (or -H5 or -MAT1) socketmodem module, and this is what we are trying to do:
- Send a special text message from a cell phone to the cell phone number assigned by Hologram, that we think should cause an unsolicited response (at the socketmodem end):
CMTI: “SM”,xx where xx is an index number of the number of unread messages stored
then when we see this unsolicited response, we read the contents of the message that was sent with:
and then we decide what to do based on the “actual text” of the received message.
- Dial the cell number with a cell (or landline) phone, that we think should cause an unsolicited response
every time the line rings at the socketmodem end, which we would use to wake up the remote device.
- In addition to sending a text message from a cell phone (as described in 1. above), with other carriers/MVNOs, we are also able to send an email to text using the assigned cellphone number as in:
Does Hologram have a way to send an email to text (ie. should it be sent to “10-digit number@Hologram.io” or what?).
Currently when we try option 1. above, with the Hologram assigned phone number we received, we never see the unsolicited “CMTI: …” response at the socketmodem end. When we try to dial 1+phone number for option 2. above, we immediately hear a fast busy signal in the calling phone receiver, and never see the “RING” response at the socketmodem end.
What are we doing wrong, or do your phone numbers work this way? If not, why pay the extra $1 to have one assigned?
