# How to Purchase and Assign Phone Numbers in TwinsAI
This guide will walk you through increasing your phone number capacity and assigning a specific phone number to your account. This is the first step toward utilizing features like Smart Dialing (automatic number rotation).
### **Phase 1: Purchasing Number Capacity**
Before selecting a specific phone number, you must first purchase a "bundle" or capacity slot for it in your Billing Settings.
1. **Navigate to Settings:**From your main dashboard, go to your **Profile** and click (the circle with your initial in it in the bottom left hand of the app), then select **Settings**.
2. **Locate Account and Billing:**Once in Settings, look for the **Account and Billing** section. Scroll down until you see your current phone number capacity.
3. **Select a Bundle Options:**Click on **Bundle Options**. Here, you can select how many numbers you wish to add to your plan (e.g., a bundle of 5 numbers).
*Note: You will see the monthly cost associated with the bundle size you select.*
4. **Complete Payment:**You will be redirected to a **Stripe** payment page. Enter your credit card information to finalize the transaction.
5. **Verify Capacity:**After payment, you will be redirected back to TwinsAI. Check the **Account and Billing** section again to confirm that your capacity has increased (e.g., from 1 to 2).
