Remove Sms hour limit (and other limits) for Android 6 ( MM )

I have a problem when sending many sms. I get that warning from Android, on which I have to choose if I allow or decline . By default I think the limit is for 30 sms/hours

How can I solve this for Android 6 Marshmallow?
I know there are some tricks for other versions of Android, but for Android 6 does anyone succeeded in some way to disable the sms hour limit?

Thank you :)
