Google make available video and voice chat for Android OS. Means soon you will be able to make call through Google talk over Wi-Fi, 3G and 4G data networks. But it will depend on your network service provider that it supports or not. The Android plus Google Chat users both will be able to use the service.

The company plans to release the service beginning with Samsung Nexus S smartphone owners. The owners will receive an over the air software update in next few weeks and they will be able to use the chat option.

But still here is some limitation, if you are not using latest version of Android on your mobile phone version 2.3 aka Gingerbread then you won’t be able to use the new features.

Even the new releases phones being sold with out-of-date software. And manufacturer companies’ often combat customer concerns around the software updates because they first confirm an upgrade will be possible in the future. Android developers are providing software updates to users such as DIY software updates.
