Do you want to encrypt the message that is saved on the device?

Messages sent with PhoneSms will not be added automatically to the device sms store.

SMS is limited to 160 text characters.

If the message is short enough then you can encrypt it, convert it to a string with base 64 encoding and send it.

For longer messages you can the code posted here: https://www.b4x.com/android/forum/threads/max-length-of-sms-message.20006/#post-115689

You can send with multi, part sms. Not importanst your message char length . Only change your sms cost I thiink you can fisrt step ecrypt your mesage. After you convert hex code.
;After you can send with out problem.

You can use my lib SMS Extra or Phone lib.

tjhose lib automatic cut your message and send. your customer (Reciver phone) get only 1 long message.
