SMS numbers

$3 for the first month, then $2 a month, paid once for 1, 3, 6 or 12 months through Razorpay. It doesn’t renew by itself. It’s a separate plan: the number isn’t paid with credits. Each plan-month includes 10 inbound text parts and 1 voicemail (up to 60 seconds, US numbers); extra texts and voicemails are paid with credits: 1 credit ($0.01) per inbound text part, 3 credits ($0.03) per picture-message (MMS) part, and 2 credits ($0.02) per started voicemail minute, taken from your credits.

Each plan-month includes 10 inbound text parts and 1 voicemail (up to 60 seconds, US numbers). Beyond that: 1 credit ($0.01) per inbound text part, 3 credits ($0.03) per picture-message (MMS) part, and 2 credits ($0.02) per started voicemail minute, taken from your credits. You can use your whole credit balance, with no minimum. When the free allowance is used and your balance can’t pay the next text, the number stops immediately: texts and calls sent to it are dropped and never shown, with no grace period and no free use. It reconnects automatically when you top up or when the next plan-month starts. To protect your credits from floods of texts, each number also pauses for the rest of the day (UTC) after 200 texts; it resumes the next day and is never suspended for this.

Not for the number or its free allowance. Credits are only used for texts and voicemails beyond the free allowance, and you can use your whole balance, with no minimum.

When you buy a number, you agree: I will use this number only for the allowed uses in the SMS terms. I won’t use it to persistently receive one-time passcodes or verification codes from other services, which our carrier, Telnyx, prohibits, and I understand that delivery of codes from third parties isn’t guaranteed.

Two things only: testing your own SMS flows (messages your own app or system sends, staging and automated tests, and building inbound SMS features), and a business contact line that your customers and contacts can text.

No. Our carrier, Telnyx, prohibits persistently receiving one-time passcodes or verification codes from or on behalf of other service providers. Delivery of third-party codes isn’t guaranteed: these are internet (VoIP) numbers, and many banks, payment apps, WhatsApp, Telegram, Google and other services refuse them or never send them a code. Numbers that keep receiving codes from other services are flagged for review and can be suspended.

Persistently receiving verification codes from other services, creating accounts in bulk, getting around another service’s limits or bans, pretending to be someone else, fraud, phishing, spam, and content our carrier prohibits: sexual or adult content, firearms, alcohol, tobacco or illegal drugs, high-risk financial content (loans, credit repair, debt collection, tax relief, cryptocurrency including crypto codes, investment offers), gambling and multilevel marketing. See our Terms and Telnyx’s Acceptable Use Policy and Messaging Acceptable Use Policy. Numbers that receive sign-in codes from several different senders are flagged and reviewed by a person; we never suspend a number automatically because of texts other people send to it. If the review finds the owner is using it to receive other services’ codes, it can be suspended without refund. Codes from a single sender, such as your own app under test, are fine.

Anyone 18 or older with a Wivrix Cloud account under their own permanent email address, using a Gmail address or signed in with a verified Google account. Temporary and disposable email addresses can’t buy numbers. One number per account.

The number stops receiving and is released to Telnyx the moment your plan ends. No grace period, no free days. Released numbers can’t be recovered, and we never give a number to another Wivrix Cloud user.

If a number gets an unusual burst of texts (30 or more texts, or texts from 10 or more different senders, within 10 minutes), we pause it temporarily to protect your credits. While it is paused, texts and calls to it are dropped and not charged. We email you once, show a notice on your dashboard, and reconnect it automatically after 60 minutes (if your plan and balance still cover it). You can resume it yourself after 15 minutes. A flood pause is never a suspension. Separately, each number takes up to 200 texts a day.

Email support@wivrix.com with the number and what happened. We review every report, suspend numbers that break the rules and cooperate with our carrier and with authorities.

Incoming calls to US numbers go to voicemail: a short greeting, then up to 60 seconds of recording. We email you a link and you play it on this page. Recordings stay with our carrier, Telnyx, and are deleted after 10 days. Voicemail on Canadian numbers isn’t available yet. You can’t answer calls live, make calls, or send texts. Picture messages show as an attachment note without the image. Each number takes one call at a time and up to 10 calls a day (UTC); other calls are rejected. A paid voicemail’s credits are taken when the call is answered and anything unused is refunded when it ends.

Not on our servers. When a text arrives we only record its ID, time, and a scrambled form of the sender’s number. When you open your inbox, we fetch the text from our carrier, Telnyx, which keeps it for 10 days, and show it to you. After 10 days it can’t be read any more.
