What do experts say about SMS used as a verb?

A short essay which raises a good question. Is it okay to use SMS as a verb as it really stands for "Short Message Service". Like in:

1. I'll SMS you later

2. I am SMSing my girlfriend

3. He SMSed me last night

"In the opinion of this journalist (for the Malaysia Star), it is acceptable to use ‘SMS' as a verb. This is not blind or foolish acceptance. It stems from our knowledge that a word can change its class (e.g. from noun to verb). Language is, after all, dynamic.
