I recently tried the Colt Wireless prepaid SIM card during a trip across the US, and here's my honest take.

The setup was surprisingly easy—just popped it into my unlocked iPhone, followed the activation steps, and boom! I had 50GB of data ready to go. Streaming maps and music while road-tripping through California was smooth with their 4G LTE speeds.

Where it shined: The hotspot feature saved me during a work emergency at a sketchy motel Wi-Fi zone. I tethered my laptop and finished a presentation without buffering (though I did notice throttling after hitting 50GB).

But here's the catch—like some reviewers mentioned, international use is hit-or-miss. While it worked fine for texting from Canada, my friend who tried using it in Panama got zero service despite the '90+ countries' claim. Colt clearly works best as a domestic SIM.

For $59/month renewal after the initial period, it's decent if you need lots of US data without contracts. Just don't rely on it as your sole international solution without checking coverage specifics first.
