Has anyone used the free version of the MagicJack app to call a non-smartphone or US land line from Ireland and/or England? My parents do not have smartphones, and don't use Skype, etc. via the computer. We do have 2 phones from Mobal.com, but using them is going to cost $1.25-$1.50/minute to call home. Just wondering if anyone has actually used this magicJack app, or if it's "too good to be true".
