Hi,

I would like to know if there is a product that would be suitable for my needs.

I live in Australia, my partner currently lives in the Philippines.There have been a couple of issues that have left me unsure about her (but at present it is just gut feeling - I have no proof). I am about to spend a considerable amount of money to bring here so would like to know which product would be suitable for me to use to monitor/read her text messages (and possibly listen in on calls as well). I saw Blueware which looked like it would be suitable but found that it only has a range of 300ft. I use a Nokia phone but am unsure of the make and model my partner uses.

Any suggestions?

Eavesdropping on IMs or phone calls is easy but illegal in most places. Even in jurisdictions that have a one party consent rule it is considered caddish. Askme dose not give advice that aids in illegal acts. Given that you are talking about international eavesdropping or monitoring the plot thickens.
