Sprint offers free international WiFi calls for your next overseas jaunt

There's just enough time to pop off for a far-flung holiday before summer ends, and Sprint's trying to make calling home from Guangzhou a little easier. The canary-hued carrier announced the other day that it's launching free international WiFi calling for a handful of compatible Android smartphones.

For better or worse, some older hardware is getting the nod first: S
amsung's Spark-friendly Galaxy S 4 will get the update before the ten other devices capable of making WiFi calls. Curiously enough, the name Sprint chose is actually sort of a misnomer. Yes, you can gab with your folks back home over WiFi, but you can fire off messages free of charge too.

Just remember that it's only WiFi calls to the US from abroad that don't cost anything -- WiFi calling Bangkok from the States will hit your wallet, as will international Wi-Fi calls to non-US numbers. Got it? Good.
