# Send your first text

Here's how to send your first SMS from LimePhone — and the one prerequisite US senders must complete first.

## Before you text US numbers: register for 10DLC

Sending SMS to the United States requires **10DLC registration**. Open **Settings → Trust center** and complete the Brands and Campaigns registration for your business. Until you're registered, US carriers filter unregistered traffic and your messages may never arrive. Some other countries also require KYC/regulatory documents before texting — the Trust center covers those too.

Trial accounts note: trials include **inbound SMS only** — outgoing SMS is unavailable until your account is upgraded and registered.

## Send from your number's inbox

1. Sign in at [dashboard.limephone.io](https://dashboard.limephone.io). In the sidebar, under **Inboxes**, click your phone number — it opens that number's conversations (calls and texts).
2. Click **New Message** to open the composer.
3. Enter the recipient's number in the **To:** field. The message sends from whichever number's inbox is open — switch inboxes to send from another number.
4. Type your message, then send it now — or schedule it to send later by picking a date and time.

The composer also offers message templates, AI rewrite, and emoji — and conversations support assigning, tagging, and archiving.

## Text a contact

Open **Contacts**, select the person, and use the text/SMS action. The composer opens with their number filled in — type and send.

## Text from Call Logs

Just finished a call? Open **Call Logs**, find the entry, and use the SMS action to text that caller directly.

## Where your messages live

All conversations — sent and received — appear in that number's inbox and on the contact's record.

That's the getting-started basics done. Explore **AI Receptionist**, SMS campaigns (on higher plans), and the rest of the dashboard from here — or ask **Ask LimeAI** if you get stuck.
