Hello,
we are facing troubles using sim hotswap feature.
We did dual sim interface accordingly to SL guidelines but no matter of AT!CUSTOM=“SIMHOTSWAPDIS” param we always get IMSI (AT+CIMI) of primary sim card. SL forum doesn’t say anything. In manuals nothing much about it. How to switch data connections between 2 sims ?
How to get access to secondary SIM thru GobiSerial (to disable PIN code for example)?
Try to execute AT$QCSIMAPP? command (with both SIM cards inserted) first and show the answer here.
AT$QCSIMAPP?
$QCSIMAPP: 0,“SUB1”,“L”
both of sims inserted…
Well, now check if second SIM intreface is enabled:
AT!CUSTOM?
You have to see the UIM2ENABLE variable set to 1.
If it’s not set, try to do this:
AT!ENTERCND="A710"
AT!CUSTOM="UIM2ENABLE",1
If above operation is succsessful, you will get an ability to select 2nd SIM with !UIMS command:
AT!UIMS=1
and switch back to 1st SIM with
AT!UIMS=0
