Mangoh green sim detect


#1

Mangoh green cannot detect sim card
root@swi-mdm9x15:~# cm radio
Power: ON
Current Network Operator:
RAT: UMTS network (LE_MRC_RAT_UMTS)
Status: Not registered but currently searching for a new operator (LE_MRC_REG_SEARCHING)
Signal: Strong signal strength (4)

root@swi-mdm9x15:~# cm sim
SIM card is absent (LE_SIM_ABSENT).

I tried to change sim2, it was not working
root@swi-mdm9x15:~# cm sim select EXTERNAL_SLOT_2
Unable to select ‘EXTERNAL_SLOT_2’.

Any ideas what I could try?

Have you power cycled the device after inserting the SIM card?


#3

Yes ofcourse. Also checked that sim_detect GPIO3 works. Stil wp7502 cannot find sim.


#4

A few more basic questions:

  1. Are you trying to use the standard SIM or micro SIM slot?
  2. Have you verified that the SIM is installed in the correct orientation?
  3. Have you successfully used this SIM in any other devices?

Try to enable USIM2 detection with at+uims=1 then power cycle. Works on WP8548.


#6

I have tried both sim slots. Sim cards are positioned right way and they are active, working well with wismo228 modem.

I changed to mangoh Red and its working. No problem with sim detection. So this is ok now.
