Turn incoming calls of, keep viber on 3G ?

[Anon]

iPhone 5; iOS 7.1

I know I can turn on Airport Mode and then turn wifi back on, so that I can stay on email and Viber but avoid phone calls. 

Can I somehow achieve the same thing when on 3G ? sometimes I want to avoid incoming calls but stay on email and Viber/skype ... ?

Any use?

I guess no is the answer.

Think the way described in that Apple thread is the only approximation.

I'm surprised that you can turn on Airplane mode and then re-enable wifi to get just wifi access but everything else disabled...

Yep. Using that for a few years now. Very handy.

I assumed it didn't work that way on Android but I just tried it and it does. Thanks.

Great way to avoid incoming when not in the mood ... But still work on email and social texting.
