Phone won't make or receive calls

@blkopns

Your Note 10 plus as a model number. Look for it in settings.  About phone. 

Unlocked model that will work: Galaxy Note 10+1 (N975U1)

Or

Galaxy Note10+ (At&t branded N975U,

N975U1*,  N975F, N975F/DS)
• AT&T branded Galaxy Note10+ 5G (N976U)

Wow, @formerlyknownas , that is pretty crazy if they won't help after last Tuesday. Before Tuesday there was zero indication to me that my 4G LTE phone would stop working because AT&T was killing off the 3G network. Why would anybody be worried?

I also don't see the need of requiring VoLTE as a part of the network upgrade. It seems to be that it's something AT&T people without any feel for their customers came up to cut costs, ignoring that people are actually using 4G LTE.

I helped family and friends, who received proper notifications from Ting, Cricket, T-Mobile, and even a senior-alarm company to upgrade. But there was nothing, absolutely nothing from AT&T. Nothing. Even on their website it was hard to find information on the 3G demise, let alone any info on the collateral damage to 4G LTE users. Disgusting.

@formerlyknownas it is N976U, however not AT&T branded. It is unlocked originally from TMobile. Although it is actually prefixed by an "SM" (SM-N976U) in my phone.

@blkopns

That's why.

If you are capable of flashing AT&T firmware for that model, I suggest you do so. Otherwise you have to replace the phone or go back to T-Mobile.

I also don't see the need of requiring VoLTE as a part of the network upgrade.

How exactly is your phone going to make a phone call if it is not VoLTE (voice over LTE capable) ? The only network available after the shutdown is AT&T LTE and 5G Network.   3g/4g is gone.

The FCC requires that phones on the network be capable of making an emergency 911 phone call which cannot be made from a virtual number and still be compliant with e911 requirements. 

If you're using a note 10 plus are you really going to be happy with a 16gb calypso that is sold for 40 bucks off of the prepaid page? Because that's the free phone they've been handing out, or something very similar like the maestro, etc.   A few people were able to get older Samsung phones that have been refurbished.   Complaints are pretty ugly. 

AT&T doesn't owe anyone a free replacement phone. Most of the people that I know who have received replacements got cheap prepaid phones.  

I have no idea how you didn't get a notification. There have been complaints on this forum for nearly two years because their phones have been rejected.

More in the past month than I can count.

#formerlyknownas That sounds like an AT&T problem, not a me problem. If the firmware needs updating one of their techs should do it as they knew the phone I was bringing and I  have a family account. Otherwise they need to provide me with the payoff I paid to T-Mobile to come to AT&Ts network. Hoping they will see this and it is determined and fixed by the ticket or some solutions that benefits me, the customer, in the end. The current situation, for this long a period, is unacceptable for any company that wants to maintain its clients.

Agree #formerlyknowas, AT&T is not currently e911 compliant. 

@blkopns

That sounds like an AT&T problem, not a me problem.

Which they can resolve by kicking you off the network. You are no longer AT&T's problem and now the problem becomes Just Your Problem. AT&T can refuse to take your money and refused to provide service. 

If the firmware needs updating one of their techs should do it as they knew the phone I was bringing and I  have a family account.

AT&T is not allowed to alter software that does not belong to them.  

If you want to alter it yourself you can Flash the AT&T firmware.  

Otherwise they need to provide me with the payoff I paid to T-Mobile to come to AT&Ts network

No, AT&T is not financially responsible because you bought a phone elsewhere, then brought it to at&t network when it's not capable of working anymore. 

You still on the phone, you could have traded it in under one of AT&T deals, you can still go back to T-Mobile or use Google fi. Or figure out the software issue yourself.  

Hi blkopns! We are here to address your unlocked Samsung Galaxy (N976U) call concern!

Due to the 3G shutdown, your unlocked device may not work on our network as only the AT&T branded Galaxy Note10+ 5G (N976U) device will work after the 3G shutdown as formerlyknownas stated. We recommend upgrading your device to a 4G/5G device that is compatible on our network, check out our available AT&T devices and the current offers we have. 

Please check out the service capabilities of your unlocked device. HD Voice for voice calls is required for unlocked devices to work on our network. Also, check out the AT&T branded devices that will work after the 3G shutdown, we are phasing out of the 3G network to make room for an even better network. 

We hope this helps! Reach back out to us if you have additional questions. Thank you for reaching out to the AT&T Community Forums!

Rhoda,

  My phone is a Samsung Galaxy Note10+ 5G. Notice the end was "5G" not 3G or LTE. Are you trying to say that the entire time I have been on the AT&T network with my T-Mobile purchased phone that I have been operating on 3G?

  The answer is clearly no, especially since my phone has very often showed 5G next to the 5 bars. So the 3G shutdown should not have affected my phone on AT&Ts network... Unless AT&T is trying to disguise unscrupulous changes to their network which are forcing people who joined from outside the network to buy newer phones from them?

  Additionally, my wife, on my AT&T plan, has an iPhone 11 Pro Max which we also brought over from T-Mobile and does not have 5G. Yet, her phone works perfectly fine. So please, until you actually know what you are talking about, do not start telling me I need to buy new equipment. It is that same kind of lazy thought and response which causes companies to lose business. Are you trying to disguard my entire family's business with your company that frivolously? That is just the kind of comment that caused me to leave Verizon before I went to T-Mobile. So many people open their mouth without thinking or in this case type, which actually requires more thought. WOW!!! You thought I was upset about this before? Just WOW!!! This may need some elevation.

  I'll be standing by waiting for the "technician" to tell me the results of my ticket.
