Sprint Galaxy S5 users are getting the much awaited Wi-Fi calling update. This is a big update for many Galaxy S5 users.
After updating your phone will get a new software version G900PVPU1ANE5. Also Sprint is rolling out the update in batches, so if you did not see the notification till now, no need to worry. You will be getting the update sooner or later.
With Wi-Fi calling you can do regular voice call over the WiFi network and particularly useful when the coverage is not good in specific area. Also WiFi calling can save a lot of phone bill when you are in roaming. Say you take your phone to France. You connect to Wi-Fi Calling and call your friend in Seattle. The call is billed like a local call to the Seattle, with no international roaming fees.
