## 1. Purpose

Vocat ("the Software") is a source-available telecommunications hardware testing system intended for research, education, development, and functional validation of Qualcomm-based cellular modules, including developer-built EC20-based hardware.

This License grants limited permission to access and use the Software only under the conditions described below.

## 2. Permitted Use

Subject to full compliance with this License, you may use the Software solely for:

a. personal, non-commercial hardware development;

b. academic or educational research;

c. use by schools, universities, laboratories, or non-profit organizations;

d. functional testing of telecommunications modules that you own or are explicitly authorized to test; and

e. testing performed with authorized test SIM cards, test eSIM profiles, development credentials, and approved testing infrastructure.

No other rights are granted unless separately authorized in writing by the copyright holder.

## 3. Non-Commercial Restriction

The Software may not be used, directly or indirectly, for commercial or profit-oriented activities without prior written authorization from the copyright holder.

Prohibited commercial activities include, but are not limited to:

a. selling access to the Software;

b. providing paid module-testing services using the Software;

c. incorporating the Software into a commercial product or service;

d. operating the Software as part of a revenue-generating telecommunications platform; or

e. distributing modified versions for commercial benefit.

## 4. Geographic Authorization

Unless separately authorized in writing, operation of the Software is permitted only within the United States.

Compilation, deployment, operation, or execution of the Software from unauthorized jurisdictions is prohibited.

The Software may implement technical controls designed to verify whether an execution environment satisfies applicable geographic authorization requirements.

## 5. Authorized SIM and eSIM Testing

The Software may only be used with SIM cards, eSIM profiles, subscriber identities, credentials, or telecommunications resources that:

a. are specifically designated for testing or development; or

b. the user has explicit authorization to use for such testing.

Users must not use production subscriber credentials belonging to another person or organization without authorization.

The Software may reject SIM/eSIM resources that do not satisfy its testing policies.

## 6. Restricted MCC/MNC Access

For security, compliance, and anti-abuse purposes, certain Mobile Country Codes (MCCs), Mobile Network Codes (MNCs), operators, subscriber identities, or network environments may be restricted.

This may include, without limitation, SIM cards associated with MCC 460.

Users must not circumvent such restrictions by modifying subscriber identifiers, device configuration, runtime state, network routing, source code, binaries, or other technical mechanisms.

## 7. Device Limits

The Software may impose restrictions on the number of modules, modems, SIM/eSIM resources, computers, or testing devices that may be registered or tested.

Users must not circumvent or artificially expand these limits.

## 8. Evaluation Period

Unless otherwise authorized, each authorized installation of the Software is provided for a maximum evaluation period of fourteen (14) days.

After completing the applicable testing activity or reaching the end of the authorized evaluation period, whichever occurs first, the user must discontinue use of the Software and remove the applicable installation.

A separate written authorization may extend this period.

## 9. Security and Anti-Abuse Controls

The Software may contain technical safeguards intended to enforce licensing, security, testing, and anti-abuse requirements.

Such safeguards may include:

* authorization validation;
* integrity verification;
* SIM/eSIM eligibility validation;
* MCC/MNC restrictions;
* geographic restrictions;
* device registration limits;
* expiration controls;
* runtime integrity checks; and
* automatic disablement or secure cleanup mechanisms.

You may not intentionally circumvent, disable, remove, patch, spoof, interfere with, or otherwise defeat these safeguards.

## 10. Modification

You may modify the Software solely for your own authorized research, development, or educational purposes.

Any modification must continue to comply with this License.

Modification of the Software for the primary purpose of circumventing licensing restrictions, security protections, geographic restrictions, SIM/eSIM restrictions, device limits, authorization mechanisms, or anti-abuse controls is prohibited.

## 11. Redistribution and Forks

Public or private forks may be created solely for legitimate development or research purposes, provided that the fork continues to comply with this License.

You may not publish, distribute, advertise, or make available a modified version of Vocat that intentionally:

a. removes or disables the anti-abuse mechanisms;

b. bypasses geographic restrictions;

c. bypasses SIM/eSIM eligibility checks;

d. bypasses device-count restrictions;

e. bypasses authorization expiration;

f. disables integrity validation; or

g. facilitates activity otherwise prohibited by this License.

Redistribution of a permitted modified version must retain:

* this License;
* applicable copyright notices;
* attribution notices; and
* notices identifying material modifications made to the Software.

## 12. Prohibited Uses

The Software must not be used to:

a. access telecommunications networks without authorization;

b. impersonate another subscriber or device;

c. use stolen, leaked, cloned, or otherwise unauthorized SIM/eSIM credentials;

d. interfere with mobile network infrastructure;

e. evade carrier security or access controls;

f. bypass lawful carrier restrictions;

g. facilitate telecommunications fraud;

h. conduct unauthorized interception or surveillance;

i. damage telecommunications equipment or networks; or

j. violate applicable law or applicable carrier/network policies.

## 13. Automatic Enforcement

Where technically implemented, violation of authorization requirements may cause the Software to automatically refuse operation or disable affected functionality.

Security-sensitive information, temporary credentials, cached testing information, or locally deployed runtime components may also be securely removed when required by the Software's security architecture.

Such mechanisms are intended solely to protect the Software and associated testing infrastructure.

## 14. No Warranty

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, RELIABILITY, AVAILABILITY, OR FITNESS FOR TELECOMMUNICATIONS USE.
