When is 3G being shutdown?

I have a 3G ZTE Z222 of which I'm fond.   My friends with Sprint have been notified of an imminent Sprint 3G shutdown. I searched that topic on this forum and found that my phone will be good till 12/2012 or "such time as there is a national shutdown."  I need something more specific as flip-phones are getting scarcer by the week, and the only 3G flip-phone offered by AT&T right now is, bluntly, junk.   How imminent is a national shutdown?

@Delcat13Tay   Oh, for sure.  And if AT&T suffers for being short sighted, that would be pretty much how they operate.  (See what they’re doing to TV).   
   3g is going to be shut off in favor of LTE and 5g.  But there is no reason to believe 3g 850 and 1900 will become LTE 2 and 5.  5g operates on lower frequency.   Now expecting a phone with only band 5 to work in the US is ridiculous.  I can’t recall when or if I have ever seen band 5, it’s all band 17/12 in my area.  
And because AT&T uses 2,4,5,12/17,30,66 for LTE, depending on just 1 of those is just not going to work.   
To be pretty blunt, if a phone doesn’t have 12/17 (which are interchangeable) it doesn’t have hardware to work after the shutdown, even if AT&T stops blocking them, because phones with 12/17 usually have other correct bands too.

I feel the same way about Google as you do about AT&T. But Google is ten
times worse. Their people are rude all Google software is intrusive,
sneaky, and just plain disgusting. Google can not be trusted and I would
never recomend anything with their brand on it. However AT&T has been
around for many, many years and will be here for many, many more years to
come. As for the pixel 3 technology that you called cutting edge, they are
already well into pixel 4 and it is supported by AT&T so that's why I said
pixel 3 is approaching dinosour technology. The thenological industry moves
so fast and to keep the money moving companies must force people to spend
the money and upgrade in order to cover their own expenses. Leading the way
like AT&T does isn't cheap. AT&T is much more reliable and trusted than
Verizon or any other second rate, low quality, limited service out there.

@lizdance40 My current phone only supports LTE bands 2, 4 and 5 in the US.  Will that be enough for coverage on AT&T after the 3G shutdown, or should I turn to T-Mobile the next time I go to the US?  It's a dual-SIM, dual-VoLTE phone with WiFi calling support.

Thats not enough for LTE coverage right now let alone in 2022 when there is no 3g anymore.  OEM's are going to have to quit being cheap and inlcude all LTE bands in all phone period.

@Delcat13Tay  FIRST CHOICE 
 
 Best Buy has about a dozen unlocked phones that are compatible with AT&T, and a few work on Verizon, and are also world phones.  
     AT&T does sell some dirt cheap, and occasionally free with activation, prepaid phones.  In general, I discourage buying phones from AT&T because of the 6 month lock policy.  (Truth be told, I discourage buying from AT&T no matter what)
    If a traveler does come to the USA with an incompatible phone and feels buying a phone they can use back home, Verizon has a much better policy if you buy from them, and most of their prepaid phones aren’t as limited, hardware wise (CHECK SPECS).  60 days after activation a Verizon prepaid phone is unlocked, even if you aren’t paying for a second month if service.  


Still a bit of a hassle for many of us, though.  For travelers from countries where dual-SIM is a common (or in some cases, standard) feature in phones sold there (especially in Asia), it is more practical for them to buy a local SIM card upon arriving at their destination and insert it in the second SIM slot, while keeping their home network SIM roaming and inside the first SIM slot.

 

That being said, as new dual-SIM phones across all price ranges now feature dual-VoLTE and are capable of receiving LTE signals on both SIMs simultaneously (as opposed to older phones where only one SIM at a time can receive LTE signals, while the other SIM remains at 2G/3G), it is high time that AT&T open up its LTE network to ALL phones that support any of its LTE bands.  As I mentioned earlier, most budget and midrange phones sold outside the US (especially Chinese brands like Xiaomi [including Redmi], Huawei [including Honor], BBK Electronics' brands [Oppo, Vivo and Realme, which are all Oneplus' sister brands] and Meizu, among others) support the 850 MHz band on 3G, and LTE band 5, while flagship and "flagship killer" models support even more (but usually not all) US LTE bands.  Refarming the remaining 850 Mhz spectrum on 3G to LTE band 5 (and opening up AT&T's LTE network to all phones) will significantly help in making sure that international travelers can use their phones in the US, whether by roaming on AT&T's network, using an AT&T prepaid SIM, or both.


You need to understand how spectrum is used in the USA they are just not going to shut down 850mhz 3g and make it LTE..  Most markets are actually 1900mhz 3g...  The US is a hodge podge of spectrum that each carrier owns some of in different areas.  In a 40 mile drive to work I see bands 2,5,12, and 30 across the drive.


Guess I'll have to find a way to unlock at least Band 12/17 on my phone.

 

And yeah, the spectrum you use there in the US can be quite confusing, like having 5 bands just for 700 MHz FDD-LTE (Bands 12, 13, 14, 17, 29), while back here in my country (and other countries in the Asia-Pacific region), we only have one band shared by networks for that specific frequency (Band 28).

@Delcat13Tay 

Yeah, you REALLY want ALL the bands AT&T uses, and probably the rest of the carriers in the US, too, at the least (per @GLIMMERMAN76 's comment, about the OEMs "stop being cheap, and including ALL the bands/frequencies").

To use ATT "effectively", you want: 2, 4, 5, 12, 14, 17, 29, 30, 66

To use all carriers (including any possible domestic-roaming), you want quite a bit more: https://www.phonearena.com/news/Cheat-sheet-which-4G-LTE-bands-do-AT-T-Verizon-T-Mobile-and-Sprint-use-in-the-USA_id77933

Man... that's a lot of LTE bands just for one country.  And to think that having support for LTE Bands 1, 3, 5, 7, 8, 20 and 28 (plus Bands 38, 40 and 41 for TDD-LTE) is way more than enough to get my midrange phone working in most places around the world (i.e. outside North America).

 

And based on my own experience with AT&T during my last trip to the US, and what I read from other users here, it's not enough that the phone supports the right LTE bands.  In fact, it was only with AT&T where I was asked for my phone's IMEI in the store before activating the SIM to see if I'll receive LTE signals on my phone.  (Well, I was using an older phone at that time, and not the current one I have, so I was only limited to 3G/HSPA+, which was already expected since my old phone did not support any of the LTE bands in the US.)

 

Nothing like that happened to me with T-Mobile during my first US trip.  (Heck, here in my country, activating a prepaid SIM is as easy as inserting it in your phone, turning your phone on, and letting the SIM sort everything out automatically.)

You cannot “unlock” something that does not exist.  The hardware is a manufacture choice.  You will eventually have to replace the phone.

I have been reading forums and websites on rooting Android devices, and it turns out that there are some phones which have some "hidden" LTE bands, as well as procedures for unlocking/enabling them through rooting and unlocking bootloaders (mostly in those using Snapdragon and Mediatek chipsets).  Not sure if they have found a way to do this on phones with Exynos and Kirin chipsets, though.

@Delcat13Tay   Unless your phone came with different models with more/different bands, that’s a really big and incorrect leap to assume it has the hardware.  And you’re likely to just brick your phone.

...which is unlocked, carrier unbranded, with dual-SIM (either two physical SIMs, or one physical and one eSIM), dual-VoLTE, and support for most US LTE bands.

@Delcat13Tay 

Sure, but this is NOT a topic for discussion, here, you have to go to some "other forums", for that kind of help...

Also, there aren't a "whole lot of phones" with "hidden bands" these days, at least not many that I'm aware of...

 

And yes, you can "get a phone to work", with "less bands/frequencies", but it will "only work until it doesn't", or "work until it needs to use a tower-radio, for a band/frequency that you don't have".

It all depends, if you only use the phone in a "limited set of places" and you know that those places have the sufficient towers/radios for your phone, then you're set (again though, unless you use it elsewhere, OR the carrier changes the tower/radio config, where you use it).

ATT has changed multiple towers/radios around us, in the past few years, if that's "any indication" or some helpful information.

 

Good luck!

@Delcat13Tay 

Yeah, the "carrier unbranded" thing is a becoming a "hard stop" for ATT right now.  A few, newer phones work, but some (even newer) ones don't, and most slightly-older ones won't work, at all (for business reasons).

This *might* change, sometime soon, or it might not, no one (customer-wise) really knows what ATT is planning here.

 

Currently, some phones that meet your description, "were working" (able to use VoLTE, and "able" to activate post 12/31), such as the OnePlus 6T, the Pixel 3a, and are now "maybe working", it depends.

Others, which are VERY current phones, are not "working at all", due to business-reasons, while ATT "sorts this out".

 

If I were you, I'd be "shopping around" your carrier, to see who has the "best deal" for your device.
