MAs will enter as PF2. Depending on the BU you are in, you will get varying titles.
Generally:
PF1/PF2 -> Engineer/Associate
PF2/PF3/PF4 -> Manager
PF5 -> Senior Manager
I would generally advice against joining the telcos if your goal is to achieve a high salary. Their revenue has been eroded over the years. I would only recommend it if you are there to gain exposure and then FO from there.
