Texting app that requires no internet?

So, i've got this friend. His parents blocked my number on his phone so we can't really talk anymore. Does anybody kno of a free texting app that doesn't require internet access? I have an andriod, not an iphone.

Not yet designed for your requirement.

Wait for years hopin for such kinda applications.

Just tie his parents down to the radiator and hang out with your friend

How would a texting app work without internet? Texting apps can't use your cell radio, so they use the internet to send the messages

No.

Its either through the carrier network or internet. No other way.

Unless you can text through dirt, thats your only option.
