I did a little research on them, bowser, and wasn't reassured.

First I visited their Web site, and tried to make sense of their FAQ and terms and conditions. I got a strong sense that the difficulty pinning down their terms is deliberate. Two things I'm pretty sure of:

Their "unlimited" data plan is limited. In the terms they don't specify a quantity of data, but paragraphs 6 and 7 go on and on about what you can and can't do with their service, with disconnection the threatened penalty; and there's a clause that lets them disconnect or cripple your service if you "abuse" it; "abuse" defined at their sole discretion.

It looks like their system runs the old GSM cell phone standard, aka "2G". Here too they went out of their way to be deceptive: The FAQ mentions GSM in passing, but also contains a gratuitous definition of 3G without ever saying they offer 3G. It's only in a footnote (!) that they clearly state the service works only with GSM phones.

As for reviews, with so many things google, it's all in how you phrase the question. Try googling "straighttalk complaints" and even "straighttalk scam" (note that Google offered up those as common searches--lots of people search for straighttalk that way).

As I said up front, the material was confusing and it's hard to pin down anything for certain about those guys; I may be wrong. But to me, the obfuscation in itself is a red flag. I'd be nervous about straighttalk, bowser. I hope you'll investigate further on your own.

I wish I could recommend a real unlimited data plan, but no such thing exists as far as I know. I'm pretty sure that even if you pay a premium price above $100, the fine print will still find a way to transform "unlimited" into "limited".

Sux.
