Are you planning to switch from your current provider to AT&T? The process is simple and hassle-free. In most cases, you can keep your existing phone number and device; just choose the plan that fits your needs and follow the steps to transfer your number. Switching is also usually free. However, if you’re still under contract with your current provider, an early termination fee may apply. You’ll also need to pay any remaining balance on your account before making the switch. Ready to get started? Continue reading for step-by-step instructions on how to switch to AT&T.

Select an AT&T Cellphone Plan That Suits Your Needs

The first step to switching to AT&T is choosing the right cellphone plan. Consider factors such as device compatibility (or whether you plan to purchase a new device from AT&T), your data usage, budget, network coverage, international calling or roaming needs, hotspot allowances, and available security features.

You may want to explore AT&T’s unlimited plans, which typically include access to 5G, hotspot data, and high-speed performance. If you’re looking to save more, consider bundling your services; for example, combining AT&T Fiber with wireless service. Contact AT&T to learn more about available bundles and offers.

Purchase a New Phone or Bring Your Own

Do you already own a device? You may be able to save up to $360 when you bring your own smartphone to AT&T. However, you’ll need to check first if your device is compatible with AT&T’s network. To do this, use AT&T’s compatibility tool; simply enter your device’s IMEI number and click Continue.

To find your IMEI number, dial *#06# on your device or go to Settings > General > About.

If your device is compatible, the next step is to unlock it. You’ll need to contact your current provider for instructions on how to unlock it.

Note: You can also purchase a new device directly from AT&T, including smartphones, tablets, and smartwatches.

Keep Your Number

Switching to AT&T doesn't mean you have to let go of your old number. You can still keep your number and enjoy the services offered by AT&T. To find out if you're number is eligible, use this tool. Just enter your 10-digit number and click Check My Number.

Once it's available, check with your provider for the transfer PIN and account number.

Your current phone service will remain active until you authorize and complete the transfer. AT&T will send you a confirmation text once the process is finished. After the transfer is complete, your previous service will be automatically canceled. If any issues arise during the transfer, AT&T will notify you via text message.

You may experience temporary mixed service for up to four hours after the transfer. If you have any concerns, contact AT&T Customer Support for assistance.

Conclusion

Ready to switch? AT&T’s most affordable option is the Unlimited Starter SL plan, which includes unlimited talk, text, and data, along with 5 GB of mobile hotspot data. Before making the switch, check with your current provider for any early termination fees first and settle any outstanding balances to avoid issues during the transfer. You may also want to use your own compatible phone to save money when switching providers. If you have additional devices, such as tablets or smartwatches, you can bring those to AT&T as well.

Why does GetHuman Write How-to Guides for AT&T Wireless Problems?

GetHuman has been working for over 10 years on sourcing information about big organizations like Comcast in order to help customers resolve customer service issues faster. We started with contact information and fastest ways to reach a human at big companies. Particularly ones with slow or complicated IVR or phone menu systems. Or companies that have self-serve help forums instead of a customer service department. From there, we realized that consumers still needed more detailed help solving the most common problems, so we expanded to this set of guides, which grows every day. And if you spot any issues with our What do I do if my Xfinity TV or internet is out? guide, please let us know by sending us feedback. We want to be as helpful as possible. If you appreciated this guide, please share it with your favorite people. Our free information and tools is powered by you, the customer. The more people that use it, the better it gets.
