Here is a tested Solution for unlocking network on Oppo a73(cph1725). Folkow all steps carefully. No risks,:)
  • Enter *#800# to open the MTK engineering settings.
  • Go to Telephony> Bandmode> SIM1 and enable the 850 band mode by checking the box and pressing SET.
  • After that enter *#39757# and after a message it should reboots itself.
  • After reboot check your signals
  • Done!!!!(y)
No need to buy the 16 digit unlock code assigned to your IMEI.
the phone still works fine on all networks.
This is not a permanent solution but works fine and It will revert back to locked after a factory reset.

after factory Reset do the same procedure to unlock it again.
never Update firmware version.
