Text message opt-in

Last updated October 2, 2026

This page shows, word for word, how a phone comes to receive texts from Crossline, a service operated by Skelvon Labs LLC. Crossline texts from (405) 766-7764. Nobody receives a recurring text until they have opted in from their own phone, and there is exactly one way to do that: send a keyword from the phone itself. An admin cannot enroll anyone. There is no web form, no list upload, and no import.

Program: Crossline, by Skelvon Labs LLC

What you receive: messages people post in the Discord channel you chose to follow, and in any Telegram group or other Discord channel bridged with it, relayed to your phone as [Name]: message, plus replies to your keywords. Your replies post in that channel and those groups, and reach the other phones following it.

Frequency: varies with channel activity, never more than 36 text segments an hour to one phone. Quiet hours are 10 PM to 7 AM by default.

Cost: free for people who follow a channel by text. Message and data rates may apply.

Opt out: text STOP at any time. Help: text HELP, or email support@crossline.stream.

Terms of Service and Privacy Policy. We do not share mobile numbers or opt-in data with third parties for marketing.

Opting in: the pinned notice and JOIN

When a server admin connects a Discord channel, Crossline posts this notice in the channel and pins it. It is the call to action. Every member of the channel can read it, and it carries the number, the keyword, and the disclosures. The follower count updates as people join and leave.

The same JOIN from a link or a QR code

An admin can hand out the number as a link, sms:+14057667764?&body=JOIN, or as the QR code below, on a flyer, a bulletin, or a screen. On a phone, either opens the person's own messaging app with the number and JOIN filled in. Nothing is sent until the person taps send: the text is theirs, it is the same JOIN, and it gets the same confirmation shown above. Crossline never sends the first text. A link an admin shares may fill in a short code after JOIN, like JOIN 7K3MD: the code says which channel's link was used, so the admin can see where followers came from. It identifies the channel, never the person, and JOIN on its own always works.

Some channels take new followers by approval. Their pinned notice reads Text JOIN to (405) 766-7764 to ask to follow this channel by text from Crossline. An admin approves each request. By texting JOIN you agree to receive texts from Crossline. followed by the same disclosures. The phone still texts JOIN first; it gets one reply, Crossline: You asked to follow #general on Maple Guild by text. An admin will look at it, and you'll get a text if they approve., and nothing further unless an admin approves, when it gets the same welcome and name prompt shown above. A request that is declined or not decided within seven days gets no text.

There is no other path. An admin cannot text an invite, add a number, or enroll anyone. The first text is always the phone's.
