After testing the Jolt Mobile Data Only SIM for a month, I have some thoughts to share. First off, the setup was surprisingly easy. The triple-cut SIM fits most devices, and activating it online took just a few minutes. I used it with a portable WiFi hotspot during a road trip, and the AT&T network coverage was solid in most areas.

However, not everything was smooth sailing. Like some reviewers mentioned, there were moments when the connection dropped unexpectedly, and the 'provider plan needed' error popped up despite proper activation. It's frustrating when you're in the middle of something important.

The data speeds were decent for basic browsing and emails, but don't expect to stream HD videos smoothly with just 1GB. It's perfect for IoT devices like my security camera though - reliable enough for occasional connectivity needs.

Customer service is indeed a weak point. When I had billing questions (yes, they kept charging after cancellation!), getting clear answers was like pulling teeth due to language barriers. Pro tip: Document all cancellation requests!

Would I recommend it? For temporary data needs or IoT devices - yes, but with caution. For primary internet? Probably not. The price is right, but the reliability issues and customer service headaches might not be worth it for everyone.
