Our customer wants to use EM7565. They have sites in many countries around the world. While testing in the US. I had to load the PRI file for ATT to connect. The SIM we use works in all countries. Do need to load a PRI file for each specific LTE carrier?
Is the sim from ATT?
The SIM is from Webbing and can use many different carriers. Before I loaded the PRI file for ATT it kept trying to connect to non US Carriers. The goal is for the LTE card and SIM to work in any country. The SIM can be tailored via a web portal. We would prefer not to have to download firmware updates after the units ship to their destination.
I remember for webbing sim, generic pri firmware should be used.
For the APN, you need to check with webbing
