A6 - SMS says OK, but nothing is sent.


#1

Hi Guys!

I was following along with “SMS via AT commands / SMS Service Not Subscribed?” and everything seems to be correct, but nothing is actually sent.

Here’s the play-by-play. (I’ve changed the phone number to protect the innocent.)

A6 Bootup:

^CINIT: 1, 0, 0

^CINIT: 2, 32, 41891

^CINIT: 8, 2048, 1

^CINIT: 16, 0, 1638410

^CINIT: 32, 0, 0

+CREG: 0

+CTZV:17/10/28,16:39:31,+03

+CIEV: service,  1
+CIEV: roam, 1

+CREG: 5

Here’s where I begin typing:

ATZ

OK
AT+CMGF=1

OK
AT+CGDCONT=1,"IP","hologram"

OK
AT+CSTT="hologram","",""

OK
AT+CMGS="13105551495"

> Did you get this?
[1B]
OK

Couple of notes:

  • I’m in Los Angeles
  • The manual says that CMGS is supposed to give back a unique identifier. It always give back [1B].
  • I’ve registered my SIM at hologram.io/start and see it in the dashboard.

Some more details:
