Makes sense. I just looked a second time at the Roamer App in the appstore for iOS and its Google equivalent. They have lowered their price for international forwarding, added a VOIP module, a voicemail to email module, and a simplified procedure to get online with a SIM brought on arrival.

I can beat their rates, but they are agressive.

Agree. As long as you have good internet connection, a VoIP might be a good idea.

Keku service works well for my purposes
