Re: Dual Sim Help

If someone calls you on a dual sim phone, does the screen show which number that person called?

Re: Dual Sim Help

That's right @evection, depending on how the caller was using their device- the contact received should appear with the relevant details.


Check out our Guide to Dual Sims and this will provide you with some more information on the feature  -Quade

Re: Dual Sim Help

Thanks Tuong,
Just to confirm it will show my number? So that I am aware which number they are calling, eg personal number or business number?
I did read the guide to dual sims and I'm afraid it did not include this information. Thanks for your help in this.

Re: Dual Sim Help

Hey @evection, I believe it does depend on the device specifically, some may show the SIM card name on screen there for each SIM. 


If you weren't able to see anything distinguishable for that you should be able to set a ringtone for each SIM to confirm which SIM is receiving that call.
