Unfortunately, when we asked Buzzirk what network they used, they couldn’t answer.
When we asked what frequencies their phones operated on, they gave an answer that can only be paraphrased as “all of them.”
And yes, we have emails that say the same thing from Buzzirk.
Bottom line, once a scam, always a scam. Avoid Buzzirk. This year’s CES March to Boredom has many things that are almost interesting along the way.
