When i make a call with my nokia 7020 i can hear the contact but they can't hear me


First you should locate the problem; phone or sim.
CHECKING FOR SIM
Put another sim in your phone.

Does the problem persitst?
Yes (The problem is not from the sim)
No (The problem is from the sim - to solve it, get another sim of your same network, call your mobile service operators, and inform them. They should help further).

Or

Put your sim in another phone.

Does the problem persist?
No (the problem is from YOUR phone).
Yes (It confirms the sim problem, and solve it as such.)

TREATING THE PHONE
The problem with the phone is that the microphone's bad. This should be replaced, and can be done at the local phone repairs.
Pending that repair, you can conveniently make your calls using a hands free device.

I hope that solved your problem?
Do have a great day.
