MC7430 cannot attach to network

IoT Modules MC/EM Series
1

Hi,
I’ve an issue with one MC7430 that will not attach/register to the network. Its working with its sibling (also an MC7430) with the same SimCard, on the exact same machine. We’ve also updated the modem firmware. Only visible difference between the two modems is in the !BAND? (TDS mask is 00…0020 on other one) and !HWID (revision is 1.0 on other one).

Hope you’ll be able to help (Thanks in advance). I’m kind of desperate right now :-/
Have a nice day,

Hi @john.dursel

Could you please provide some information about your module using below commands?

AT!IMPREF?
AT!IMAGE?

Hi @Donald ,
Thank you for your answer. Here is the result of the two AT commands.
AT!IMPREF?
!IMPREF:

For the AT!IMAGE command, I’ll post it as soon as I can get it (working in remote today).

HI @jean-francois.meyer

This means your module can be attached to 3G networks.

You can use AT!SELRAT=06 to force module to only LTE and check that your SIM card supports LTE from your mobile service provider.

You need to enter AT!ENTERCND="A710" command to unlock password.

Please help to tick “Solution” if your question is answered.

Hi @john.dursel, @jean-francois.meyer

This problem is caused by an old hardware version 0.2. This one maybe doesn’t allow newer firmware versions on it. You can try downloading the firmware 01.08.07.

Please refer to My EM7455 has no carrier pri and a carrier/config name missmatch
Firmware updating Dell 5811e with ancient firmware (SWI9X30C_00.08.02.00) - #16 by ctx1001

Hi @Donald,

As you’ve seen, @jean-francois.meyer has took over the subject. Thank you already for your time and your advices. We’ll test the old firmware and let you (and the forum) know if it has solved this issue.
