RockBLOCK+ modem not detected #33

Hello, I am trying to use the BasicSend for sending a message to a RockBLOCK+ unit from an Arduino Mega 2560.
I have tried with several pins, such as Serial2 and Serial3 as well as using software serial on pins 10, 11, 12 and 13.

All i get is:

Starting modem...
Calling internal begin
Powering on modem...

AT
Waiting for response OK

<< >> ATT
Waiting for response OK

I am supplying the RB+ with 12V, and i can see it oscillating between 0 mA and 219mA, every second or so.
I have tried to change up the RX and TX, as mentioned in earlier issues. I have the Sleep Pin set to Pin 4.
At this point I am out of ideas. I am quite inexperienced, so I have probably overlooked something. Please help.
