To send a text from your app without a sim card through wifi, you can implement a SMS Gateway API BUT, but the receiver must be using a SIM Card.

You can do this using Nexmo.

After signing up for the free trial, you will receive an api_key, api_secret, number (from), and will be allowed to test out this with up to 10 whitelisted numbers.

You can use Nexmo's API by making a simple HTTP call to: https://rest.nexmo.com/sms/json?

Include the required parameters (api_key, api_secret, from, to, text) and the optional parameters you choose (if any) and you are ready to send your first text.

Also, our Android SDK is coming out soon so make sure to keep an eye out for that!

Full disclosure, I work at Nexmo

For more information on how to implement this you can check out the docs here
