is there an Android app similar to IMessage that sends texts without phone service

[LisaLisa712]

Does Android have an app similar to IMessage that will still send texts to other Android phones like IMessage does to other Iphones when no phone service is available?

Thanks

Yes, there are tons of them.

But none which are integrated into the calling app the way imessage is, if that's what you are looking for.

WhatsApp is what you're looking for.

Kik messenger works over wifi. I use it with no problems at all.
