Otherwise, you may be in a bit of difficulty... I believe third-party WP8 apps are not permitted to send SMS directly (because of the risk of malware texting premium services, one of several popular tactics for Android malware). It's quaint and antiquated, but does she have fax? Otherwise, there's always the option of recorded telephone calls, though those can be a pain to transcribe.
Some good thinking here especially about emailing her to her phone using <phonenumber>@<carriername>.com which I'll have a look into. I think she uses an iPhone too so seems ludicrous that she doesn't use her email (I don't know but guess you probably have to have one to have an apple account).
As you have guessed though I was hoping for something slick and polished and didn't realise third-party WP8 apps aren't permitted to send SMS directly. Thank you for helping me.
Frustrating really because I don't feel it's reasonable to demand she use a form of communication if she doesn't want to (this is hypothetical I think she must use email! maybe she really doesn't... she never was very tech... who doesn't use email?). I guess I'll have to think about writing an old fashioned letter maybe... god? has it come to this!
EDIT - just noticed I could email a conversation from whatsapp so maybe that's the answer.
