Buying Guide
Key considerations for choosing prepaid mobile data:
- Coverage and network: Confirm which networks the SIM supports and where you’ll use it most (US-only, or cross-border in Canada/Mexico).
- Data priorities: Do you need unlimited data, or is a high-speed cap acceptable? Some plans slow data after a threshold.
- Device compatibility: Check if your phone is unlocked and GSM-compatible. Some plans prohibit use in modems or non-phone devices.
- Activation timing: Some SIMs require advance activation or scheduling; plan accordingly if you need immediate service.
- Hotspot and extra features: If you rely on hotspot or international calls, verify hotspot speeds and international options.
- BYOP readiness: Bring Your Own Phone programs can save money but require self-activation steps.
