Every RelaxedSIM data plan has two limits: a data allowance (for example 24GB) and a validity window (for example 360 days). Your plan ends when either limit is reached — whichever comes first.
How a RelaxedSIM data plan works
- Example: 24GB/360 days. You can use 24GB over 360 days. If you use all 24GB before day 360, the plan ends early. If day 360 arrives with data left, the plan still ends.
- Free trial first. Every SIM starts with a free 100MB/7-day trial the first time it connects. After the trial is used up or expires, the purchased plan begins automatically.
- Data-only service. RelaxedSIM plans provide mobile data for unlocked phones, hotspots, security cameras, trail cameras, GPS trackers, and other IoT devices. They do not include calls or SMS.
- Top up anytime. When a plan ends, recharge the same SIM through the ICCID box on relaxedsim.com — see how to buy a data plan — to add a new plan.
This design gives you flexibility: you control how fast the data is used, and the validity window gives you plenty of time to use it.
Frequently Asked Questions
What happens when my data runs out before the validity date?
The plan ends when the data allowance is fully used. Inserting the SIM into a device after that will not work until you buy a new plan for the same SIM.
What happens when the validity date passes with data left?
The plan expires on the validity date even if data remains. Recharge the SIM to start a new plan.
Are these AT&T prepaid data-only plans or T-Mobile data-only plans?
RelaxedSIM plans are not carrier-store plans, but they are prepaid data-only plans that use the AT&T, T-Mobile, and Verizon networks. The SIM is not tied to one carrier and is pre-activated, so the same card works in phones, hotspots, cameras, and IoT devices without AT&T activations or a T-Mobile.com SIM order.
Does the free trial count against my purchased data?
No. The 100MB/7-day free trial is separate and is used first. Your purchased plan starts only after the trial is used up or expires.
