Hello,
I’m using the EC200S with support for the 450 MHz LTE bands 31 and 72.
The module works fine if using our “normal” providers like Telekom, Vodafone and Telefonica.
However, I’m struggling with the dial-in for our provider with the 450 MHz (450connect, plmn = 26219).
For this provider, I’m configuring the bands for band 31 and 72 only.
If I try to establish a connection via AT+COPS=1,2,…, I get a “phone failure” error.
Btw., he more or less same procedure works fine with our BG95 Modem if I try to register for LTE-M.
Any idea on how to find the root cause for the “phone failure”?
