I like your idea Amanda. I especially like your low-tech solutions. I think women could find huge comfort in these contacts even if these are not immediate (which is probably more an issue in our fast paced society than in other areas of the world)
I was just thinking about one issue, how can it be prevented that 'the wrong people' enter into the matchmaking service and obtaining valuable, private information from partners of detainees?
Maybe some kind of check or screening could be possible (although this would make the overall concept more complex).
Or participants could be instructed in some way to discuss issues without providing vital, personal information.
Like your idea Amjad. As an extension on the phone idea: Maybe a solution like Skype (out) could work to make it cheaper in use. Also person in need could text, or make a 'missed call' to an information number, and they could be called back (so the people in need of advice do not need to spend their scarce money). You could also make this into a marketing vehicle, that people can donate telephone minutes to Amnesty (maybe also left-over minutes from their mobile phone subscription).
