We are trying to obtain a firmware update, if available, for a set EC25-AF modules, current firmware rev EC25AFFAR07A14M4G_01.003.01.003
The modules won’t connect using the inserted SIMs, known to be functional (works in other hotspots and phones). Band support already confirmed with the carrier.
it is the latest firmware version
The EC25-AF modules do not work with our Verizon SIMs, so firmware may have been flashed improperly. We want to know the download for the firmware image and the correct Android system drivers. Otherwise we will have to use an alternative from a different vendor.
I have sent them to you,pls check
Perhaps it is worth presenting some evidence of this?
Could you please send me a copy of this latest fw for EC25-AF? Thanks
I have sent it to your email,pls check,and I hope you can click the 
for me,thx
