oppo f1s

I bought an oppo f1s and unlocked it from the optus network to use my telstra sim but i cant make or recieve any calls. It has full bars of service but still wont make or recieve calls. I can still use my data and text. Whenever someone tries to call me i goes straight to message bank and i get a text that i missed a call. How do i fix this?

Re: oppo f1s

Really sorry to hear that @tiahb 😞 

 

Hmm as the service isn't with Optus it's likely that you'll need to contact Telstra as there may be a setting on your voicemail which is causing all of your calls to be sent straight to voicemail.

 

Let us know how you go.

 

Cheers.

Re: oppo f1s

No the problem is that Optus disables the other carrier bands (specifically UMTS - WCDMA-CLR-850, and LTE Mode Bands 5 and 8). I have the same problem and was told that it could be unlocked (obviously to use with another network) they did not pass on the info that they change the specs to what is actually on the OPPO site to stop it being able to be used on other networks.
