receive call from 2 iphones

[tnh]

Hi, I recently change my iphone. meaning: switching the SIMM from 1 to another and also transferring all data and application. Everything is working fine, but a funny thing is happening: I receive call now on the new phone (with SIMM) and also on the old phone (no SIMM). Note that both are on the same home wifi while this is happening. Probably not when I will be outside of my home (?). Does any one has a technical answer of this functionality?

Thanks

You are still signed up with Apple ID on the old phone.  If you log off Apple ID on old phone, then you will not see this issue.  If your old phone is off Wifi, then this should not happen also. 

With Apple devices, you can receive phone calls on iPad or macBook also when connected to Wifi.

@tnh  Yes if you haven’t done a factory data reset on the old phone and it’s still connect to wifi this is normal
