The Sim card costed 30MVR in february 2012, see: http://www.wataniya.mv/page/products/wprepaid

Data Package

there are different Data Packages available which can be activated by sending "GO" to a special number depending on the package, see on the same page as before: http://www.wataniya.mv/page/products/wprepaid

without these packages the internet access is rather expansive, so use these.
