@jmakiv does it mean you have a functioning dataconnection?
If you do, would you e willing to give some more hints?
Thanks!

Same here, I can get a connection to the network, but no ping or anything.
Did you get it to work @Procrasto ?
I see the unit is out of stock on the M5 store and can not find anybody on the net with a success story...
Could it be this unit is not capable of working in europe?

I have the same problems.
My experience:

AT+CFUN=1
+CREG: 2
+CGREG: 2
OK
+CEREG: 2
+CGEV: ME PDN ACT 1
+CREG: 1
^MODE: 17,10
+CREG: 1
+CEN1: 1,204
+CEREG: 1
+CIREPI: 0
+CNEMS1: 0

at+cops=?
+COPS: (2,"T-Mobile NL","T-Mobile NL","20416",7,1),,(0-4),(0-2)
OK
AT+IPSTART=1,"TCP","185.78.197.71",3000
+CME ERROR: 30

I too get +CME ERROR: 30 on all ping actions.
The sim is ok, I get data when I use it in a smartphone.

Is anybody out there successfully transmitting data with this unit?

any help would be greatly appreciated!
