Consistency of the AT!SELRAT=? results

Can you please confirm if the AT!SELRAT=? results and/or indexes will ever get updated by firmware or operator change on EM7455?

I am getting the following results

AT!SELRAT=?
!SELRAT: Index, Name
00, Automatic
01, UMTS 3G Only
02, Not Supported
03, Not Supported
04, Not Supported
05, Not Supported
06, LTE Only
07, Not Supported
08, Not Supported
09, Not Supported
0A, Not Supported
0B, Not Supported
0C, Not Supported
0D, Not Supported
0E, Not Supported
0F, Not Supported
10, Not Supported
11, UMTS and LTE Only
12, Not Supported
13, Not Supported
14, Not Supported

I want to make sure that the updated results will not affect existing valid mappings.

Hi akn,
Please refer this ticket MC7455: !SELRAT: Unknown RAT mode
You should use AT!BAND=? instead of SELRAT

Thanks,

You can never guarantee something like that, its very unlikely to change however and obviously its not going to change for a given firmware so if you are happy with a firmware for a given product then either order the unit with that firmware or load it on in production.
