Dear mrhaav!
I changed my sim card to another provider. This provider does not have a public ip, I would get a NAT-ed IP. I modified the APN, but the script doesn't want to connect. I wonder why? Can you help me with this?
Strange
Can you run the script manually with debug=true and paste the result?
Stop the Mikrotek service first.
I can't see anything 
Sorry, I misunderstud you! I stoped the service, and start the script manually. Here are the results:
It is very interesting that there is no LTEmodem entry in the log. With the other SIM / operator there are many log registrarion
You got a network error code +CNEC_GSM: 55,1. I don't know why.
I'm on vacation right now, but I can take a closer look in mid next week.
An other interesting. If I disable the "mikrotikR11" service, that You created for me, and I use my own script on boot than I got IP, and the router is online. My old script:
#!/bin/sh
ifdown WANN
sleep 3
echo -e "AT+ZGDCONT=5,"IP","internet.telekom",0" > /dev/ttyACM0
sleep 3
echo -e "AT+ZGPCOAUTH=5,"","",0" > /dev/ttyACM0
sleep 3
echo -e "AT+CFUN=1" > /dev/ttyACM0
sleep 3
echo -e "AT+ZDHCPLEASE=216000" > /dev/ttyACM0
sleep 3
echo -e "AT+ZGACT=1,5" > /dev/ttyACM0
sleep 3

Hi
We could try to use profile number 5 instead. Change to 5 here:
# Configure PDPcontext, profile 5
atOut=$(COMMAND="AT+ZGDCONT=5,\"${PDPtype}\",\"${APN}\"" gcom -d "$modemDEV" -s /etc/gcom/run_at.gcom)
[ $debug = true ] && echo $atOut
atOut=$(COMMAND="AT+ZGPCOAUTH=5,\"${username}\",\"${password}\",0" gcom -d "$modemDEV" -s /etc/gcom/run_at.gcom)
[ $debug = true ] && echo $atOut
and here:
+CGEV )
[ $debug = true ] && echo $dateTime $URCline
if [ "$URCvalue" = 'NW PDN DEACT 5' ]
then
[ $debug = true ] || logger -t LTEmodem -p 6 Session disconnected, release DHCP lease
kill -SIGUSR2 $PIDudhcpc
elif [ "$URCvalue" = 'EPS PDN ACT 5' ] || [ "$URCvalue" = 'NW PDN ACT 5' ]
then
[ $debug = true ] || logger -t LTEmodem -p 6 Activate session
atOut=$(COMMAND="AT+ZGACT=1,5" gcom -d "$modemDEV" -s /etc/gcom/at.gcom)
fi
;;
BTW. can you run AT+CNEC?

In the script I need to change profile 1 to 5 or insert the new profile 5?
Please, include the "?".
COMMAND="AT+CNEC?" gcom -d /dev/ttyACM0 -s /etc/gcom/getrun_at.gcom
Change to profile 5. Change from 1 > 5 three times in the # Configure PDPcontext and two times in +CGEV.
After I changed the 1 to 5, the script is works i think:

Yes, I agree, it looks promising.
The endurance test starts. What is the different between profile 1 and 5?
I think profile 5 is the default profile +CGEV: NW PDN ACT 5.
So is it conceivable that the previous sim could also work with profile five?
Yes, it would probably work with profile 5 as well.
Does the profile number have anything to do with the public ip?
No, the profile number will not affect the IP address. Only your service provider can decide if you get a public IP or not.
Okay. It seems to be okay. It is online , and if necessery it reconnects.
