Simple translations would (usually) work fine. We often use that in games, too.
However, remember that, when using social skills, you're limited to the language skill in question - that would be 0, here. That makes sense - when translating via commlink, with all the pauses, incorrect phrasings, etc inherent in computer translations, you won't be able to properly express yourself (remember, even with 21st century computers, perfect translations can't exist because different languages use fundamentally different concepts).
Not to mention that using a commlink to translate might come over badly to a lot of people, giving further penalties. And it's slower, much slower to communicate that way.
