Buyer guidance
What to know before ordering.
Low-data tracking plans
GPS trackers usually send small location and status packets, so annual low-data plans can be enough for many devices. High-frequency tracking uses more data.
SMS setup note
Many GPS trackers require SMS commands to set APN. Because SpectrumSIM is data-only, some trackers need to be configured with an SMS-capable SIM first, then switched back to SpectrumSIM.
Setup path
Get online in four steps.
Confirm the device is unlocked and supports US 4G LTE or compatible 5G bands.
Choose Plan A for AT&T and T-Mobile or Plan B for AT&T, T-Mobile, and Verizon.
Activate online, choose a data plan, and complete payment before final setup.
Use puffin as the APN for most current SpectrumSIM cards and enable data roaming if available.
