If you do well in mobile, you will have a lot of money and a bright future.
I have several friends (girls) who do mobile sales. Their salary was not high at first (1000+ commission). Working for two years, the average monthly income is about 4000 RMB!
You have a high degree, which is your advantage! As long as you behave well and show your ability, it is no problem to be promoted to a regular employee, and promotion is also possible!
But remember: education does not mean ability, so work hard!
Come on!
