Start with a base plan, then add the features you want, so you only pay for what matters to you. * * * Create a planCreate a planManage Build-A-Plan accountManage Build-A-Plan account ### About Build-A-Plan Build-A-Plan works with an unlocked, AT&T-compatible smartphone with eSIM. You begin with a base plan and update the features as your needs change, so your monthly cost is based on the features you choose. When you create your Build-A-Plan account, you can choose to transfer your current number or get a new one. To transfer your number from another provider, make sure you choose __Transfer my number__ and provide the requested info from your current provider, including your [number transfer PIN](https://www.att.com/wireless/transfer-your-number/ "Link opens in new window"). ### Sign up for Build-A-Plan 1. Go to [att.com/buildaplan](http://www.att.com/plans/build-a-plan "Link opens in new window"). 2. Select your plan. The default plan includes unlimited talk and text and 1GB of data. 3. Choose your data and hotspot options, if you want to add them. If you want hotspot data, make sure you have an equal or greater amount of wireless data. 4. Enter your address and select __Submit__. Then select __Continue__. 5. Provide your device IMEI number (your EID number might also be required; you can find these by pressing __\*#06#__ on your smartphone). 6. Follow the steps to create an account and password, transfer your phone number or get a new one, and add your payment info. __FYI:__ Build-A-Plan currently supports single-line accounts only. If you need another line, each line or user will need their own account. ### Check Build-A-Plan usage and balance To view your usage details: 1. [Sign in](https://www.att.com/acctmgmt/mywireless "Link opens in new window") to your Build-A-Plan account. 2.

[Sign in](https://www.att.com/acctmgmt/mywireless "Link opens in new window") to your account, then choose __Make changes to plan__. If you upgrade your monthly data amount or add hotspot data, changes take effect immediately. If you downgrade or remove data add-ons, changes will take place at the start of your next renewal period. What happens if I use all my Build-A-Plan data? If you use all your plan data, your speeds slow to 128Kbps until your renewal date. Need more data? You can purchase the __5GB for 5 days__ add-on for your line or hotspot. 1. [Sign in](https://www.att.com/acctmgmt/mywireless "Link opens in new window") to your Build-A-Plan account. 2. Select __Explore other add-ons__. 3. Choose __5GB of additional mobile data for 5 days__, then follow the prompts to confirm. What is Wireless Account Lock, and how do I turn it on or off?

Tap the __person__ icon. 3. Scroll to and select __Wireless account lock__. 4.
