Jim uses AT&T.net and had a similar login issue as Cheryl. It took him three days to find a US number to solve the problem. Customers can call AT&T at 800-772-3140. It's based in Tustin, CA, they should be able to help.
Cheryl is having trouble logging into her SBC email. Leo says that Cheryl has a "legacy email," with SBCGlobal, which was sold to AT&T and then outsourced to Yahoo. As such, Leo just thinks that the SBC log-in has expired and is no longer working. So Cheryl will likely have to transition to ATT.net for all her email needs if she wants to stick with that company. Try going to AT&T's web portal and try signing in with the same credentials.
Patrick is a rideshare driver, and he uses Number Sync to connect his iPad to his mobile phone. It's from AT&T. Do other carriers do it? Leo says that it's exclusive to AT&T. TMobile does have its own called "Digits." So check that out. Either way, it allows you to make and receive calls on any compatible device. But it isn't perfect.
Karen has a Windows 10 computer that gives her a message saying her settings are out of date. Leo says Windows won't send that message to her. But her mail program would. And since her mail has disappeared, then it may be that since Verizon is selling Yahoo, AT&T is telling Karen to update her settings. She will want to go into the mail program and delete the account. It won't delete the mail, just the portal to get it. Then Karen will have to re-add it using her login and password. The credentials Karen used to use won't work anymore. Use mail.yahoo.com moving forward.
Elaine recently had AT&T rewire her house for UVerse service, but a day later, her phone won't dial out. Leo says a call to AT&T to ensure Diane has an outbound calling plan is a good idea. It may also be that Diane's phone is an old analog phone and so it doesn't make the tones that UVerse looks for. Leo says to check out Pioneershoppe.com for one that supports UVerse. There's also DialGizmo.com.
Bill got a Samsung Galaxy Fold 2 for his birthday and he keeps getting knocked off the internet with it while being on the phone, through AT&T. Leo says it could be the location, with a cellphone tower that is having trouble. Leo says that it would be a good idea to go back to the AT&T store and have them reset it. From the chatroom ... here is a conversation about how to reset it.
Randy wants to know when the 5G iPhone be announced? Leo says it was expected this week, but Apple didn't. Nor did they hint it would be coming soon. But in the last quarterly results phonecall, Tim Cook said the iPhone 12 would be delayed. But the word on the street is, that Apple will announce it next month. Just in time for the holiday season.
Tony moved from AT&T to Comcast for his landline service, and while he was out of service for 4-5 days, the service so far has been wonderful.
Every day, data goes out from his iPhone at the same time (3,6,9 pm). Sometimes it is a small amount, sometimes it's 300 MB. What gives? Leo says what AT&T is doing is listing the data in "chunks", not what is actually happening, If it was minute by minute, Bill's bill would be 50 pages. Most likely the phone is "phoning home" to various apps, doing app updates, etc.
Alex would like to use his own router with AT&T U-verse, can he? Leo says only if you aren't getting your TV service from U-verse. That requires AT&T's proprietary router. You could turn the AT&T router into bridge mode or IP Pass through, and then use your router with it. That's possible. Will it affect the speed? Leo says no, but it could affect whether you can select your own DNS service. You can also try using DNS over HTTPS using Cloudflare to eliminate the ability for AT&T to see what you're doing. But that's advanced stuff.
