How to mirror sms and calls to another phone out of country Is there any app that allows you to use your phone out of country? sorry I don't really know how to word it.

the situation im thinking of is like this:

your main phone(left out your house and left on)

and a secondary device(that you're using outside of the country)

So say I'm in the Philippines on vacation but don't want to miss any calls or texts,

would I be able to use the phone, kinda of like a proxy? 

ex:

device in Philippines connecting to device at home over internet, calls and texts that go to main phone at home get sent to device in other country over internet. and can send text and make calls on main phone but doing so on out of country device.

sorry if it sounds a bit confusing
You could try an app like this. I haven't tried it myself, but the description seems to fit your needs.
