The TALKSIM USA Unlimited Data Only SIM Card is designed for IoT devices, offering 5G and 4G LTE coverage through AT&T or T-Mobile networks. It includes 10GB of high-speed data for 30 days, with unlimited data at reduced speeds thereafter. This review delves into its performance, setup, and user experiences.

Performance and Coverage: Users report mixed experiences with network reliability. While some found the connection stable and efficient, others faced issues with dropped connections, particularly on the T-Mobile network in areas with poor coverage. The SIM card automatically selects the best available carrier signal, but this doesn't always guarantee optimal performance.

Setup and Compatibility: Installation is straightforward—insert the SIM, update the APN to 'unet', and restart your device. The SIM is compatible with a wide range of unlocked 4G/5G IoT devices, including security cameras, GPS trackers, and mobile hotspots. However, it does not support voice or text services.

User Experience: Many users appreciate the no-contract, no-credit-check policy and the absence of hidden fees. The initial 10GB trial data is sufficient for testing purposes. However, some users noted that post-trial data plans are more expensive compared to other providers.

Customer Support: While some users found customer support helpful, others struggled to resolve connectivity issues despite multiple attempts. This inconsistency in support quality is a notable drawback.

In summary, the TALKSIM USA Unlimited Data Only SIM Card offers a flexible and cost-effective solution for IoT device connectivity but may require patience with network reliability and customer support.
