Refund for 1-year prepaid plan

Prepaid does not refund.

Which phone do you have?

Unfortunately, AT&T does not refund prepaid services. It doesn't matter whether you've purchased a single month or a full year.

What model phone? 

If it's not whitelisted, you will need to replace it. 

wasted 300bucks, I have a Huawei Mate 20 pro, I really don't want to change phones. 

That brand has been banned in the USA for a few years.  Even T-Mobile imei check will refuse it.

Yeah, but the customer service rep that I talked to convinced me that it will not be affected, hopefully I can get even a portion of my money.

Again they don’t refund. If you want to keep the phone then find a provider that it will work on and eat the loss. Otherwise get a compatible phone.

That's why I posted T-Mobile's IMEI check. If T-Mobile won't take that phone, no one will. Huawei is still banned.

But if he's okay owning a phone that's mining his personal information... 🤷🏼‍♀️

Let's clarify which devices are compatible with AT&T's upgraded network, markanthonyana! 

We apologize for the misinformation provided to you. It’s important to check the model numbers next to your device to make sure it’s still supported since the 3G network shutdown. The Huawei Mate 20 Pro isn't on the list of supported devices. Please take a look at the list to find a compatible prepaid device. As our ACEs mentioned, AT&T PREPAID doesn't offer refunds. We'd be more than happy to provide a courtesy credit to your acocunt for the inconvenience. If you'd like to accept this alternative, reply back and let us know.

Thank you for visiting the AT&T Community!

@ATTHelp. You are setting a precedent.

ATTHelp providing a one month credit so the OP can have time to replace his phone is reasonable. 

Huawei phones should be blocked from network by imei. 

If ATT had an imei check, it would have been blocked in the first place, rather than allowing it on the network and buy a full year's service

 I just want to refund the unused 11 months, which I paid upfront.

  We can hope they OP is happy with $25 ($300÷12).

Hi, man I had the same problem and almost same situation as you. just sharing what worked for me. Call the billing department. and ask for a refund, I got refunded the full amount with taxes and all around $327+. 

based on comments on this thread is inaccurate, who ever said you cant get a refund on services that is not rendered? that is wrong good thing I got my money back. and you should too! demand it!

switched to other carriers and never coming back to at&t . I even read some mocking your phone choice, goodluck with that mentality that at&t or iphone does not mine your data.

PREpaid?

Yes, PREpaid we have the exact same plan for 1 year. Just had a different phone, but same scenario my phone also supports 4g/5g, but not on the list. 

@formerlyknownas. Interesting bit of information.
