以下具法律效力的完整條款，以英文列出。

1. Price and term: $100 per year paid upfront, or $12.99 per month. Your plan renews automatically every year or every month (the plan you chose) unless you cancel the renewal before the renewal date.
2. No refunds: payments are non-refundable, including after cancellation and for unused time or minutes. The only exceptions: if we cannot deliver your number within 72 hours after you choose it, you get a full refund, and any refund the law of your country requires.
3. Immediate start: you choose your number right after payment and we set it up straight away. By paying you ask for the service to start immediately and you understand that, where a withdrawal (cooling-off) right applies, you lose it once the number is delivered.
4. Cancelling: you can cancel the renewal anytime in the app. Your number keeps working until the end of the year or month you paid for.
5. Your number: we rent the number to you while your plan is active. If the plan ends or a renewal is not paid, the number is suspended, kept for 30 days (90 days on the monthly plan), and then released. A released number may be given to someone else and cannot be recovered.
6. Outgoing calls: 300 minutes per month, to US and Canadian numbers only. Each call is rounded up to the next full minute. Unanswered calls are free. When your minutes run out, outgoing calls stop until your monthly reset date or until you buy a top-up.
7. Top-ups: 100 extra outgoing minutes for $5. Top-ups are used after your monthly minutes, are non-refundable, and stay valid as long as your number is active (they carry over when you renew).
8. Incoming calls: fair use up to 300 minutes per month. Above that, callers are sent to your voicemail until your monthly reset date.
9. Monthly reset: your minutes reset every month on the day you bought the number (for example the 12th). Unused minutes do not carry over.
10. Voicemail: included. Messages up to 2 minutes each, up to 30 per month, kept for 30 days.
11. SMS: you can receive texts from US and Canadian senders. Sending texts is not included. Texts from other countries usually cannot reach US numbers.
12. No emergency calls: this number cannot call 911 or any emergency service. Always use a local mobile line for emergencies.
13. Verification codes: WhatsApp and the popular apps we tested send their codes to this number. Some banks and a few services may still refuse internet (VoIP) numbers, so we cannot guarantee every single service.
14. Internet and app needed: calls and texts need an internet connection and the TripoSIM app, with notifications and the microphone allowed. Call quality depends on your connection. A phone that is off, offline or has notifications blocked will not ring; callers then reach your voicemail.
15. Fair and lawful use: personal and small-business use only. No spam, robocalls, call centres, harassment, fraud or illegal activity. We may suspend the number without refund if this rule is broken.
16. Availability: not sold to residents of, or for use in, sanctioned countries. You are responsible for following the laws on internet calling in the country where you use the app.
17. Changes: we may update these conditions with notice. Your price and allowances stay fixed for the period (year or month) you have paid for.
