RC7611 over the air update question

I am looking to do OTA updates to the RC7611 modules. My question is: If someone is using a Verizon sim, should I just send the Verizon update file or does the sierra file contain module upgrades and should be sent too (or is it just for embedded sims). Sending all the files (sierra, generic, tmo, att, verizon) takes too long and sometimes leads to connection issues at restart.

Have you tried FOTA by airvantage?
