These Terms & Conditions (the “Terms”) govern your access to and use of the apps, websites, virtual numbers, voice, messaging, and related products and services provided by Tierra Digital Ltd (“SimBuster“, “we”, “us” or “our”) (collectively, the “Services”). By creating an account, purchasing, or using any Services, you agree to these Terms. If you do not agree, do not use the Services.
Important: The Services do not provide access to 999/112/911 or other emergency services and are not a replacement for traditional telephone services.
1. Eligibility & Accounts
1.1 Eligibility. You must be at least 13 years old to use the Services. If you are under 18 (or the age of majority in your jurisdiction), you may use the Services only with the consent of a parent or legal guardian. Certain features may be restricted to users 18+.
1.2 Account Registration. You must provide accurate and complete information, including a verified email and mobile number, and keep it up to date. You are responsible for all activity on your account. Keep your credentials secure and notify us immediately of any unauthorised use at support@simbuster.com.

2.1 Overview. SimBuster provides software applications and connectivity that enable calling and messaging using virtual telephone numbers (“Virtual Numbers”). Some features are free, others require payment (“Paid Services”).
2.2 Consumer Use Only. SimBuster is for personal communications with your known contacts. Marketing, advertising, promotional, or other business messaging/calling is not permitted.
2.3 No Emergency Calling. Calls or messages placed via the Services cannot connect you to 999/112/911 or other emergency numbers. Keep a traditional phone service available for emergencies.

2.5 Third‑Party Dependencies. Service quality depends on your device, operating system, data/Wi‑Fi connection, and third‑party networks outside our control. We make no guarantee of uninterrupted or error‑free service.
3. Virtual Numbers
3.1 Allocation. We may allocate one or more Virtual Numbers to your account. Numbers are licensed—not sold—to you for your subscription term. We may change, reclaim, or reassign numbers as required by regulators or carriers.
3.2 Inactivity & Reclamation. Numbers may be reclaimed after non‑payment, expiry, or prolonged inactivity. Reclaimed numbers may be reissued and cannot be guaranteed for re‑assignment to you.
3.3 Caller ID. We may present a SimBuster or carrier‑provided caller ID. You must not spoof or manipulate caller ID to mislead recipients.
4. Messaging & Calling Rules (Acceptable Use)
You must comply with all applicable laws and the rules of carrier networks. Prohibited uses include:
- Any business, commercial, marketing, or promotional communications.
- Bulk/mass messaging, auto‑dialers, or automated/templated campaigns.
- API access, integrations, or automation (we do not provide an API); each message must be composed and sent manually by a human user in the app.
- Spam, phishing, scams, fraud, harassment, threats, hate speech, or abusive content.
- Illegal content or activity; child sexual abuse material (CSAM); sexual exploitation; promotion of violence; instructions for illegal acts.

We may investigate suspected violations and suspend or terminate access to protect users, networks, and partners.
5. US/Canada Consumer SMS Compliance
5.1 Personal Use. SimBuster messaging is for personal communications with known contacts. Marketing, advertising, or promotional messages are not permitted.

- STOP (also CANCEL, END, QUIT, UNSUBSCRIBE): we block further messages to that recipient from your number.
- HELP: we return a help message with basic info.

6. App EULA (End User Licence Agreement) & Software
6.1 Licence Grant. Subject to these Terms, SimBuster grants you a personal, revocable, limited, non-exclusive, non-transferable, non-sublicensable licence to download, install, and use the SimBuster app(s) and related software (the “App”) on devices you own or control, solely for your personal consumer use, in accordance with these Terms and any applicable app store rules.

The App may include or interact with third-party software development kits, libraries, or services (including operating system features, push notifications, analytics, and payment systems).
