Move SIM to new device?


#1

I want to use my SIM in a different device (Feather FONA) from the one it was activated on. Should this work, or does it require changes on the Hologram server side?


#2

I’ve moved SIM’s around on various devices, including iPhones, with no problems. I believe the Hologram activation is fortunately only SIM-specific, and not device-specific.


#3

Hmmm…I’ve got it working on a Fona808, but when I move it to a FeatherFONA (800) it no longer get a cell connection.

All other commands seem to work fine, but AT+CIICR fails every time.

Interesting. There might be an issue with FONA or the library/code. As this post also mentioned. SIM808 (FONA), good signal but no IP (ERROR: Timeout when calling AT+CIFSR)

It is highly unlikely it would be a SIM/network issue if it works in one device and not another.


#5

That other thread is me also. Slightly different problem. I can get things working well enough in the SIM808 this morning, but when I move the SIM to the 800 it fails.

I may just give up and order another SIM.

More info…the Hologram SIM never registers with the carrier in the 800 device:

AT+CREG?
+CREG: 1,0
OK

Even if I issue an AT+CREG=1 command.

In the SIM808 it registers within a few seconds. This leads me to believe that there is something on the carrier side that is device-specific. With a Ting SIM I needed to contact them to move their SIM from one device to another. I was hoping that wouldn’t be necessary with Hologram.

Hi Daniel - Our Hologram SIMs by default do not lock to any specific IMEI as @MichaelM mentioned.
A few things:

  1. What list of operators is returned in the 800? AT+COPS=?
  2. Can you provide our SIM # to support@hologram.io ? Would like to take a further look from the network side

#8
AT+COPS=?
+COPS: (2,"T-Mobile USA","TMO","310260"),,(0-4),(0-2)

I’ll send the SIM # via email.

Thanks for your help.

Nevermind, guys - I think the device is defective. I tried it with a Ting SIM and it reports itself as a 800L instead of an 800H, and can’t read the CCID at all.
