I have entered the unlock code into my oppo F1, restarted the phone with new network sim card in it, BUT phone cannnot connect to new mobile network
Are you receiving an error prompt of any sort?
You're welcome to send us a private message. I need the IMEI and the unlock code that's been generated.
I just want to compare the code with what we have on record. If necessary I can always request a master unlock code for you.
