EM7421 No internet Access

I tried only “sphone.pelephone.net.il”

Then you need to do more test

Do you have specific tests that could help me solve the issue?

Hi,
I have two EM7421 cellular modems:
Both have the same chipset (QUALCOMM 4G) but one is a product of China and one is a product of Vietnam.

Those modules behave a little bit differently, then I want to know
Does this mean that the modems were made in different factories, or does it mean something else?

As said before, try other APN

Yes, they are from different facotries

Hi,
I’ve tried to change the APN, but I’ve been unsuccessful.
The APN that is currently filled in the modem is “internet.rl”, which is an APN for a different cellular operator in Israel.
it seems that I can’t change it.
Could you please help me to make a factory reset to the cellular modem.
Thank you,
Roei

Who fill the apn to be “internel.rl”?
It seems your windows will change module’s apn…
Can you change it after at+cfun=0 ?
You can check at!rmareset for factory reset

Hi,
I have finally resolved the issue with the APN on my cellular modem. I was able to get internet access by following these steps:

I factory reset the EM7421. This caused the APN to disappear from the At+cgdcont command.
I updated the firmware of the modem.
I updated the AT!USBCOMP command to 100D.
I made a reset with AT!RESET.
After following these steps, I was able to get internet access on my cellular modem.

I would like to thank you for your patience and help in resolving this issue.

Best regards,
Roei
