After testing the TALKSIM Unlimited Data SIM in my security camera and mobile hotspot for a month, I've got some real talk about this budget-friendly IoT solution.

The Good: Setup was surprisingly simple - just pop in the SIM, enter 'unet' as APN, and boom! Connected to T-Mobile's network instantly. The automatic carrier switching between AT&T/T-Mobile actually works well in urban areas (my NYC apartment got solid 4G LTE).

Watch Out: Like one reviewer experienced, rural coverage can be spotty. My trail camera in upstate NY kept dropping connection until I moved it closer to a window. Also true about the speed throttling - after burning through the 10GB trial (about 7 days of continuous streaming), the 256kbps crawl is painful.

Pro Tip: This shines for temporary setups. Used it during a road trip in my unlocked tablet and GPS tracker - worked perfectly across 5 states. But for permanent installations? Might want to compare long-term plan costs first.

The lack of customer service seems hit-or-miss based on reviews. Personally didn't need support, but that's definitely a gamble.
