Connecting EC200U to one whitelisted static IP address

Hi,
I have been trying to configure ec200u such that it does not take any dynamic IP address to access the internet but so far it was unsuccessful. Can you kindly help to access the internet with one static IP address. Additionally, I did try to PPP dial but it replies with NO CARRIER.

I have been using these commands so far,
AT+CGDCONT=1,“IP”,“airteliot.com”,“xxx.xx.xx.xxx”
AT+CGATT=1
AT+CGACT =1,1

Even though I try to configure the address in AT+CGDCONT it changes as soon as the command AT+CGACT=1,1 is sent. IP address is displayed by using the command AT+CGPADDR

I have the IP address with me but I am not able to connect to EC200U using the same to access the internet. Additionally it is an M2M SIM card.

[2024-05-17 12:00:55:506_R:] AT+CGDCONT = 1,“IP”,“airteliot.com”,“xxx.xx.xx.xxx”
[2024-05-17 12:00:55:506_R:] OK
[2024-05-17 12:00:59:716_S:] AT+CGDCONT?

[2024-05-17 12:00:59:773_R:] +CGDCONT: 1,“IP”,“airteliot.com”,“xxx.xx.xx.xxx”,0,0

[2024-05-17 12:01:09:805_S:] AT+CGATT = 1
[2024-05-17 12:01:09:867_R:] AT+CGATT = 1
[2024-05-17 12:01:09:867_R:] OK

[2024-05-17 12:01:27:592_S:] AT+CGACT =1,1
[2024-05-17 12:01:27:656_R:] AT+CGACT =1,1
[2024-05-17 12:01:27:656_R:] OK
[2024-05-17 12:01:31:517_S:] AT+CGDCONT?
[2024-05-17 12:01:31:585_R:] AT+CGDCONT?
[2024-05-17 12:01:31:585_R:] +CGDCONT: 1,“IP”,“airteliot.com”,“yy.yy.yyy.yy”,0,0

[2024-05-17 12:01:31:585_R:] OK

The yy.yy.yyy.yy indicates the address change and xxx.xx.xx.xxx represents the static IP address given.

Any response is appreciated.

Hi @Navya_A
Can I ask if the SIM card is a SIM card with fixed IP? The module cannot control the IP address assigned to us by the network. Can I ask why you need a static IP?

Hi @lyman-Q ,
To answer to your first question, the network provider claims that the SIM card has a static IP address.
Secondly, we would require static IP address to make our cloud operations more secure.

Hi @Navya_A
I think for a moment, this may be related to the APN configuration, may I ask you the apn information you configured is told by the operator? There is no limit for the module to obtain the IP from the network, normally if the operator fixed the IP, then we will receive a fixed IP.

Hi @lyman-Q ,
Yes I have configured the APN according to the details given to me. I even tried to set a blank APN and still yielded the same results

Hi @Navya_A
Ok, thank you for your reply. I also want to ask if this SIM card can achieve the effect you want on other devices? In addition, do you want to obtain IPV4 or IPV6 IP?

Hi @lyman-Q ,
I have not tested in any other devices as such. Additionally it is an M2M SIM card and let me know what other devices do you recommend to test it on, as of now I have only EC200U only.
I am trying to obtain a IPV4 address.

Hi @Navya_A
Any other device will do, I just want to make sure this SIM card works.

Hi @lyman-Q ,
I will check and let you know.

Hi @lyman-Q ,
Actually the SIM card has a dynamic IP address but the destination IP address is whitelisted but still I am not able to access the internet from EC200U module.
Any suggestions on what can I do about this?
