Decision sheet — What a tracker can do
SIM card and SMS tracking claims
You saw a claim that a SIM or SMS can be tracked.
Verdict
Separate access
A SIM identifier is not a general permission to read SMS or locate a phone. SMS access is separate from location access and is controlled by the device and service.
How to check
- Separate the claim into location, SMS and account access.
- Review the specific permission and device requirements.
- Use your carrier for a lost or compromised SIM.
The honest limit
Do not treat a SIM number as a key to someone else’s messages.
