turn off data and use WiFi

[speedlever]

Adara, I can't speak for operations abroad, but here in the USA, your assessment is essentially correct:

According to this link, calls and SMS go over 1x. MMS (picture messages and group messages) go over 3g/4g. Wifi is for data only, not voice calls or SMS/MMS. Or that's what I get out of it.

I assume it works the same on AT&T, TMo and Sprint too.

I have no idea if/how VoLTE will affect that dynamic.

I'm with you speedlever - your comment was reasonable and didn't deserve to be quoted in a disagreeing manner. In the end you guys all agree so... no disagreeement.

Moved into the Galaxy s4 forum.

Btw, as long as your connected to WiFi, carrier data won't be used regardless

Cheers :thumbup:

Thanks for your knowledge. if you have time can you give your opinion on chip sets I choose to go with the quad processer and (snapdragon) over the dual quad...thoughts? this is all new but I have done some research

I've had my s4 i9500 for a week or two now. On my OS I can simply un-check data and it does exactly what I had hoped it would do, only connect using Wi-Fi and no data charges on my bill. Using 4.2.2 jellybean.
Thanks for all of the help and feedback from all who replied. Your help was what made me decide to go Samsung.

Adara, do you know if it is the same with the newest firmware update?
