Activating a RelaxedSIM data SIM is easy: there is no registration form, no app, and no carrier setup. The SIM activates itself the first time it connects to the network. Follow the steps below for any unlocked IoT device.
How to activate your SIM in an unlocked IoT device
- Power off the device.
- Insert the SIM. Punch out the correct size from your 3-in-1 card (Standard, Micro, or Nano) — see which SIM size your device needs — and insert it into the SIM slot.
- Power the device on and wait 30–60 seconds for it to register on the network.
- Confirm the connection. Your free 100MB/7-day trial starts automatically the first time the SIM connects, so you can verify signal and compatibility before buying a larger plan.
APN settings for IoT devices
On most unlocked devices the APN is applied automatically. If the device connects but has no data, set the APN manually to globaldata and leave the username and password blank. See our APN details page for the full settings, or the Reolink 4G camera guide for cameras.
Frequently Asked Questions
Do I need to activate the SIM before inserting it?
No. RelaxedSIM SIMs are pre-activated. Insert the SIM into an unlocked device and it connects automatically; the free trial and any purchased plan begin on first connection.
Why is my device connected but has no internet?
Check the APN setting (globaldata, blank username and password), make sure data roaming is enabled, and confirm the device is unlocked and not restricted to another carrier.
Is the SIM data-only?
Yes. RelaxedSIM SIMs provide mobile data only and do not support calls or SMS, which is normal for IoT and camera use.
