RelaxedSIM Data Only SIM Card

Best for hunting and trail cameras that need seamless data without activation steps. This SIM card provides true plug-and-play operation: insert and power on, with automatic network switching among AT&T, T-Mobile, and Verizon to maximize signal. A 100MB free trial period (7 days) lets you test device compatibility before your main plan starts. Suitable for devices requiring auto-connectivity and broad U.S. coverage. Best for data-focused deployments where quick setup matters and no voice service is needed.
Caution: Activation-free use relies on the device recognizing the SIM, and the initial 100MB trial is limited. If your camera requires consistent, higher data usage from day one, plan for ongoing data beyond the trial.
Mint Mobile SIM Card (3-Month Plan)
Best for budget-conscious users who want a short-term data boost on unlocked devices. This 3-in-1 SIM card provides nationwide service with a simple activation process and is suitable for tablets, mobile hotspots, or cameras needing a compact plan. Choose this if you want bundled talk/text/data for a limited period and can manage program renewal later. Limitation: the plan is time-bound and requires renewal to maintain service.
EIOTCLUB Data SIM Card (360 Days)
Best for security and hunting cameras that require year-long data without recurring contracts. This SIM card advertises nationwide 5G/4G/LTE data across major networks and operates without a traditional voice plan. It’s well-suited for IoT devices and cameras that need stable data in remote locations. Choose this if you want a long-term, contract-free option with universal device compatibility. Limitation: data-only service means no voice or text capabilities.
Prepaid 10GB Data SIM Card (90 Days)

Best for unlocked phones and routers that only need data with a modest initial allotment and a defined validity period. The 10GB plan covers general data use for a few months and is suitable for temporary deployments or travel scenarios. Choose this if you want a straightforward, no-frup contract option without voice or SMS. Limitation: 10GB may run out quickly for high-traffic devices or cameras with frequent uploads.
EIOTCLUB Data SIM Card (No Contract)

Best for nationwide IoT device networks and security cameras that require a data-only SIM with no contract. This card emphasizes 5G/4G LTE data across major U.S. networks and supports triple-cut SIM formats for compatibility. Best for devices needing flexible, no-commitment data plans. Caution: Verify the exact data levels and renewal terms, as listed features emphasize flexibility rather than fixed data quantities.
Buying Guide
What should you consider when choosing a data-only SIM card plan?
