IoT Modules MC/EM Series

Hello ,
I’m trying to work with the MC7710 modem .
I have connect it to my minicard dev board - but all I get is “Searching…”
it seem that he is unable to connect to the network
the sim is open and working ,
I have also try to change it to work on WCDMA and north America - but he won’t save my this setting
I can see that the signal is good (-61dBm) and if I do search I can see all the network that around me
so what is the problem? even try to connect to 3G network
can someone help\guide me ?

I have download and install to the modem the latest firmware from Sierra website
SWI9200M_3.5-Release8-SWI9200X_03.05.24.00

Thanks ,

maybe the problem is in my cellular provider?
even that I try to connect GSM\WCDMA?

I know the SIM is working (using MC8790)

in the Sierra Wireless Discovery Tool -Network-Mobile Network Operator
Operator Limited Service Pelephone (name of my cellular company)
Registration LIMITED SERVICE
GPRS Registration LIMITED SERVICE

Signal strength the green bar is at max (5 lines)

what?
