Issue getting new MC7430 Units online

[Daniel.vdl]

Hello

I have used the MC7430 modules in the past and have recently received new orders. I am having an issue where i can not get the new modeling on the network. (Telstra in this case).

I have confirmed i am running the latest FW on the older and new modules, and am using the same system for testing. The older module will connect to the LTE network fine. Using the same sim with the new model they show as only have UMTS available, and when you try to connect to the network they say they are missing an API. However even after manually entering an APN i get the same issue.

Any help would be greatly appreciated. Thank you

How about you force it to use lte with at!selrat ?

[Daniel.vdl]

Hello

I have attempted what you have suggested and ran the same command set below. After locking it to LTE only, it shows in the windows system as having no reception. This is using the same SIM and antenna as the working modem and so should have no issues getting reception.

What do you think I should try next?
