Have this module but Sptint is shutting down B25, B26, B41. The only options using T-Mobile is B2/B12, which does not work well in my area. Any suggestions?
According to Technical Specifications MC7455:
The MC7455 module supports 4G LTE Frequency Bands: B1, B2, B3, B4, B5, B7, B8, B12, B13, B20, B25, B26, B29, B30, B41.
Please refer to the below link for more details:
You can use the latest FW Generic SWI9X30C_02.38.00.00.
EM/MC74xx Approved FW Packages
You can use the below command to check Frequency Bands support:
So the 7455 generically supports these bands and this CA combo as per the PTS. We will not have a specific firmware to enable support it, if the bands are enabled on the unit then the firmware will automatically use it (assuming it is assigned by the network).
