I was always a bit hesitant to switch to a mobile service that only offered Message2Txt as the only answering service. The technology is not capable of accuracy without human review, so is not fit for such a purpose.
It simply can't handle uncommon proper nouns, different accents or words with foreign origins.
But to make the experimental technology even more useless, they impose a 10 second limit on the soon-to-be-garbled-anyway text. Here's a little sample of some recent messages I received from a switchboard number:
"Hi beater beater pumpkin. This is tundra (?) from polymer (?) grass (?). We'd like to offer you a position of employment. Due to a high volume of applicants we need confirmation by close of business. Please call me o".
Like they say, "buy nice or buy twice as many SIM cards to save some money on 4g data and stay unemployed you cheapskate loser". They're not very nice.
Telstra has the same thing so it's not just for cheaper services (and yes I hate them too; I need longer than 10 seconds to convey my message)
