According to the creator of this app https://play.google.com/store/apps/details?id=com.bamf.smslimittool.donate&hl=en, the limit, since 4.4.1, is 30 messages in 30 minutes.

It also notes that the limit is present to safeguard against malicous programs, so setting it very high is potentially a bad idea.
