USA Data Sim Card

RelaxedSIM sells no-activation prepaid data SIM cards for the USA. Insert a SIM into any unlocked phone, 4G hotspot, security camera, trail camera, GPS tracker, or other IoT device and it connects automatically on the AT&T, T-Mobile, or Verizon networks — no contracts, no credit checks, no carrier lock. Every plan starts with a free 100MB/7-day trial so you can confirm coverage and device compatibility before your paid data begins.

Frequently Asked Questions
Do I need to activate a RelaxedSIM USA data SIM?
No. RelaxedSIM data SIMs are pre-activated and plug-and-play. Insert the SIM into an unlocked device and it connects automatically; there is no app registration, activation form, or credit check.
Which RelaxedSIM plan should I choose?
Start with the 100MB/7-day trial if you only want to verify coverage and device compatibility. Choose 3GB/30 days for a short project, 6GB/90 days for seasonal use, or 12GB/180 days and 24GB/360 days for cameras and IoT devices that run for months.
Which devices work with these SIMs?
Any unlocked phone, tablet, 4G hotspot, router, security camera (including Reolink), trail camera, GPS tracker, or other IoT device that accepts a standard 3-in-1 SIM. The SIMs are data-only and do not support calls or SMS.
What are the APN settings?
APN: globaldata. Username and password: leave blank. Most unlocked devices set the APN automatically; see our APN guides if your device needs manual setup.
Which US networks are supported?
AT&T, T-Mobile, and Verizon. The SIM automatically connects to the strongest available signal and routes data through low-latency US servers.
Do you sell AT&T, T-Mobile, or Verizon prepaid SIM cards?
RelaxedSIM is not a carrier store. Our prepaid SIM cards are data-only and pre-activated, and they connect on the AT&T, T-Mobile, and Verizon networks without AT&T activations, a T-Mobile prepaid card, or a Verizon Wireless prepaid SIM card setup. You buy a SIM card online, insert it into an unlocked device, and top up the same card whenever you need more data.
