Yes. Put your phone in Airplane mode and activate WiFi.
If you can still send and receive SMS, you're good!
I tested this the other day with other users who had their RCS enhanced features enabled, had airplane mode on, mobile network off, and wifi on.
Only messages between RCS enabled clients will be sent over wifi. if you send a message to someone who is not RCS enabled or just uses SMS, the message will not send until you turn on mobile network connection.
So RCS to RCS works over wifi, but not RCS to SMS.
Thanks Pauly for detail explanation.
Is there any other advantage of goole messenger (RCS) over regular SMS service? I mean whats difference except send message over wi-fi to RCS enable device.
Rogers/Samsung are offering the S7 Galaxy for $0, beware as there are issues with the phone, I have the S7 Galaxy, albeit with AT&T, nevertheless, the Enhanced LTE Services and Advanced Messaging features do not function properly or do not work, whether this is an issue in Canada I don't know, ask the question before committing. My text messaging receive feature only works intermittently, meaning when a text is sent to me, I do not receive it immediately, it takes four to five days to receive it and when I do, I receive them all at one time, then after a day or two, the text receive feature shuts down again. I have talked extensively with AT&T and the ICU division about the problems, they finally admitted that the phone has problems. They say they have isolated the issues but it's in the phone, they will replace it at no charge, ... if you go with it, ask for the lastest version to save yourself a lot of grief and a guarantee of no hassles. I can not say if the newer version works correctly, I'm in Canada for another six weeks and will exchange it for the newer version when I get back.
How can I enable RCS on my Rogers Wireless line?
I have a OnePlus 3 running Nougat, with the latest version of Google Messenger installed (it actually came pre-installed on the phone, and has since been updated to "Messages").
However Rogers still thinks I have an LG G4 since that is the last phone I bought through them via HUP.
I am concerned that since Rogers thinks I still have a G4, that they are not enabling RCS on my line.
Thank you for posting your query in the Community. I heard good reviews of OnePlus 3, hope you are enjoying it. The service, RCS is enabled at our end and it's not account or device specific as long as it is running Android 4.4 or above.
There is no action you have to take from your side except to enable the Enhanced features. You can find this option in Settings/Advanced. If you don't see the "Enhanced features" option yet, eventually your device will receive the prompt from Google to enable it. The prompt will look similar to the image below;
Thank you for your patience!
