Hy All!

I've read topics related Neoway M590 module, but i can't find answer about why my M590 module can not register the SIM to the network. Of course if i put SIM card to any other device (phone,tablet) works! No pin code setted either...

After startup Neoway says:

MODEM : STARTUP
+PBREADY

After this i ask the register status, it's sometimes
AT+CREG?
+CREG: 0,4

sometimes 0,2

but never 0,1

Regarding to AT command set 0,2 means connection refused by network
0,4 means unknown code (i think means unknown problem occoured).

When i check signal strength, it says:

AT+CSQ
+CSQ: 3,99
OK

what is not too bad... sometime i measured 5,99..

Please help me out, theoretically M590 need to handle all network provider's SIM
(This one is telenor).
