When I am using TRB245 with FW TRB2_R_00.07.00. I could not set the custom APN to "mobiledata", as the system always revert back to "3gpronto". Due to this, I could not have 3/4G data from this SIM card in this TRB245.
When I set the FW to TRB2_R_00.02.06.1, I can correctly set the custom APN, and the SIM card is working OK.
Would you please help to check this out.
