I've tried the free trial, which is 10 SMS and went through them in half an hour or so (and that's because they don't reply very quickly). Haven't even got to the parts that I customized, I was still at "Hello there, how are you!", "Did you have a great day?" "Oh, and your?".

That's 4 SMS a day or so. At this point, I would simply use a chatbot, since they are fine with the basic conversations that I would manage to get to in 4 sms.

I guess you could have two 50 SMS conversations a month, but even then, good luck fooling someone into thinking this is your real lover.

The only plus I can see is that you can have someone tell you "Alright, if she is really your girlfriend, ask her something only your close friends know about you" and "she" would manage to answer.

Not very convinced about the service.
