Question s22 ultra B/E/0/N Carrier question - Samsung Galaxy S22 Ultra

Was planning on buying and seen in a eBay ad that the E version doesn't work for att/cricket. Can anyone confirm or deny?
I specifically need an international version for root purposes. So E/0/B. If any one of these three can be confirmed working on any GSM network specifically red pocket H2O AT&t cricket or whatever else is GSM I need to know soon. Thanks.

Do a google search Phones That work on At&t. If it is not on list At&t will disable your Sim. Trust me I can no longer use several of my International devices on At&t. And if you call and have them whitelist the imei that trick only works for a day or so. Their network now detects unauthorized devices. There are a few F devices on the list but not many.

How do I do that search for all the GSM carriers? Because I'm known to switch from one GSM to the next couple times a month.

[Q] Droid Maxx: Not activated on Verizon, won't work

After several long calls with Verizon and help from Motorola insiders, I have been given to understand that:
1. Droid Maxx if not activated on Verizon, before leaving US, cannot be used on other carriers (say in Europe or Asia).
The reason is the SIM unlock cannot be done by the customer support since they won't see the device in their network if it is not activated first.
2. The activation cannot happen outside US, since Verizon does not have a network.
So bottom line is get the device activated before you import it from US.
Now, my Droid Maxx is locked to Verizon. I know the boot loader can be unlocked. Will this help me in flashing something that can get rid of the SIM lock that Verizon has in place.
My device is an employee edition so perhaps there was some extra protection added there by Verizon.
Please help.
I do not have a Maxx, but I'm replying because you PM'd me asking to take a look at this thread..
It has been my experience that Verizon's 4GLte phones are sim unlocked (on the GSM side) out of the box. I thought that was a condition of VZW's 700Mhz spectrum auction win? One potential issue is does the phone support the needed bands out of the box (think Bionic where a hack was needed to enable bands needed for T-mobile).
That being said, if your Maxx is truly SIM LOCKED, then unlocking the bootloader wont help you SIM unlock, nor will flashing a 3rd party Rom after unlocking the bootloader.
where are you located, and who is your carrier? Do they use CDMA for voice, or GSM? What happens when you put a non-VZW sim in the phone?

Thanks Mark.
The phone Droid Maxx does support these bands since there are others who are using the same phone on GSM networks in the country.
The networks in India are:
2G capabilities GSM 900, GSM 1800
3G capabilities UMTS 2100
4G capabilities LTE 2300 (this one won't work with the phone, plus my carrier does not have it either)
The CDMA is CDMA 2000 - but I have not been able to try with a CDMA SIM, but that one has a higher probability of working.
When I put a non-VZ SIM, and set to Global mode, it does not detect any signal and the search network does pretty much nothing. The automatic mode tries to connect but then throws an error saying "can't connect to this network at this time"
I am using a brand new nano SIM card (which now is back in my Moto Defy with an adapter.)
Earlier I had a normal SIM converted to a nano SIM and that one did not work, but after I put in APN manually, I was able to access data.
I tried another user's cut-nano SIM and that one worked for data out of the box (another GSM provider).
Ditto for me, but I am using DroidMini... I also have DroidMAXX which is working great (even unlocked its BL and rooted it)...
I am also from India... Using it in GSM networks... I may get one Nano CDMA SIM to test later and will report here for sure...
Thanks...

Well, we have interacted on Rimweb recently.
The radio on the Droid series is the same. The difference between the mini and the maxx in your case is that the mini has never been activated on VZ network and hence it is SIM locked. Whereas, the Maxx would have been purchased as a used item (perhaps just activated and then sold off?). So that takes care of the SIM unlock part.
Yesterday I spend around 60 minutes with global support, VZ.
I escalated the issue to the supervisor.
He checked and said that the IMEI is clean and not in any sort of negative list. So there is nothing else that they can do.
He also said, the phones are unlocked by default for global use.
Obviously they don't want to dig deeper into why three phones are not working on GSM in India.
I am now running out of avenues. Does anyone have some debugging tool which can log what is happening when the phone tries to log on to the network?

The current Droid Maxx that Verizon sells supports the following..
LTE Band 13/4 700/1700
EDGE/GSM: 850/900/1800/1900,
HSPA/UMTS: 850/900/1900/2100 (download speeds to 42.2 Mbps, upload speeds to 5.76 Mbps
From what you listed, the Maxx should get GSM/Edge/HSPA/UMTS coverage there. And of course, no LTE.
The CDMA side of the Verizon phones is still "locked" so I also would not expect CDMA to work. In other words, if your carrier NEEDS CDMA, stop trying.

I've been through this with some trying the Moto X in India, and I've been through it while trying my T-Mobile and ATT sim's in my Verizon Moto X.
From what you are describing, it sounds like your APN settings for your carrier on the phone are not set right.
Example... When I put my T-Mobile SIM into my Verizon Samsung Galaxy S4, I get "unknown sim" and bars, but no network connectivity. Nothing works. By going into the mobile network settings on the phone and adding an APN with the T-Mobile settings, features like calling, SMS, data, etc. start working. I have had occasions where I thought I had the APN right, as calls and data worked, but MMS only partially worked (would send but not receive). When I do have the settings right, everything works. Similar thing happens on my Moto X with T-Mobile SIM.

Unless you have an active account with Verizon, and are trying to use their service when traveling, Verizon wont help you. In other words, unless you are trying to get your Verizon phone, working on Verizon's Global Roaming service, on your currently active Verizon account, they wont help you.
Even if you are a Verizon customer who is just traveling and popped out your VZW SIM in favor of using a local prepay sim to save data/voice costs, once you pop that VZW SIM out, they wont assist.
But you have received confirmation of what I said.. the GSM side is unlocked.
The SIM you are trying to use is from a GSM India carrier? As long as they only use GSM (no CDMA required), your only hope will be working with them. Telling them your phone is SIM Unlocked and going from there. Or finding a local message board for the carrier, and hope people are discussing use of "3rd party" phones, and you might get some help there.
I really think it will come down to the APN settings for the GSM carrier not being correct on the Maxx.
I can't offer any more than that. Sorry.

I have now put in a CDMA SIM card, but run into another problem with that. I will activate that SIM on another phone and then pop it in the Maxx again and check. But CDMA should work fine as reported by other users.
But the problem is the GSM part, because that is what we need to get working.

That is bad on the part of Verizon. I have purchased a Verizon device off-contract and that device is a global one. So I am entitled to some support from them even if I am without a service plan.

Yes. Local carrier. And for now, there are three such XDA members who have been facing the same issue. In one case, a member was able to make calls and receive calls and also use data. Then after a few minutes, the SIM invalid message popped up.

APN settings are pretty easy. I did that with my earlier SIM and I got data working. There was no voice, so I gave that SIM back to the carrier and got a brand new nano SIM. Now, nothing works. The old and new SIM are for the same number and same service provider.

Right, you got just DATA working with the APN settings, but the correct APN settings are also needed for SMS, MMS, Phone calls, etc.
I've had an issue where I had voice but no data, and it was related to APN. I've had an issue where I had voice, SMS, data but no MMS, again, it was related to APN settings for the carrier you are using.
So good luck!
the problem we sorted out to get gsm working in india first the phone must be activated on usa to get it work on india so can anyone help us > @s_u_n
So, after using the phone for a week on GSM with all application updates installed, I can safely state that
1. Verizon activation is not needed for non-VZ networks to work (at least outside US).
2. A full FXZ was installed and it probably solved the modem configuration mess that the phone might have been. Perhaps it unlocked something?
3. Four corner activation bypass method was used (as described in earlier Motorola phones).
Either 2 or 3 solved the problem
There was nothing to do with APN. Data works even without any APN settings out here, just like on my Motorola Defy.

T-Mobile Note Edge on AT&T.

I have been searching for an answer and have not gotten a clear and definitive answer. Does the T-Mobile Note Edge variant work on all AT&T LTE networks without issue after being unlocked? According to tbr Samsung website both models have the same bands with the t-mobile Edge have 2 additional bands
I have the att model but would really like to be part of the dev community. I have a week and a half to return my att model. I would buy the t-mobile model if it works completely on the networks. Anyone out there using a t-mobile Edge on ATT. Thanks

Think I can help answer a few Qs.
Am using a Straight Talk sim (ATT) in my T-Mo Note Edge. Getting 8-15+ mb/s down...2-4 mb/s up (more than enough for me). Followed rooting method posted by TekHD. Did not see unlock procedure for T-Mo Edge.
T-Mo does hold your unlock hostage for 2+ months or $100 (didn't see this stated and argued). Unlocked through a reputable unlocker through fleabay (~$24 I think - Tmo also recommended...go figure).
Hope this helps.
Wish someone can release a qualcomm kernel w OC/UV/governors and thermal control soon...

Yes, Using one right now. You do not need to unlock it at all it will work right out of the box with an AT&T sim as will all T-Mobile Phones.. This has been a thing for years. There might be some obscure T-Mobile phones without perfect LTE Band or Data support. Every major model will work perfect with absolutely no unlock don't waste your money. I actually called T-Mobile before throwing my gophone sim into the Note Edge T-Mobile variant and cautiously asked if they will blacklist the imei of a phone that is using an AT&T sim. The T-Mobile representative kindly, calmly, and with conviction said that no you will not have your device blacklisted, and that all T-Mobile phones should work out of the box on AT&T. Enjoy not paying for an unlock code! I'll upload pictures of my note edge running AT&T data services via an AT&T gophone sim if you don't believe me. It actually put the APN information in for me automatically too! Meaning I did not have to enter in carrier specific AT&T APN, the software on the Note Edge T-Mo variant picked up the different carrier and entered the APN settings automatically. Woot woot

Unlocked Galaxy S6 and S6 Edge from other Carriers

Here is confirmation for anyone wonder if the Galaxy S6 unlocked from ATT or Tmoibile will work on Verizon just like the iPhones 6 6+ or Nexus 6
I have both ATT and Tmobile Galaxy S6 in hands, unlocked, inserted Verizon sim card in and there is no signal
However, when I check "About Device" it shows my phone number
Mobile Network Type: LTE
Service State: Out of Service
and LTE came up for a second and never came back on
I think they blocked the LTE bands or so to stop people unlock their phones using on another carrier

Unlocking att s6
Hi was it easy to get the att version unlocked from a 3rd party website or did you get it unlocked from ATT?
thats why i prefer buying unlocked phones from Amazon and use on any network on my choice. i wonder if this locking phones is cant be investigated for being anti competitive or messing with our rights somehow

You guys are confusing "unlocked" terms. There's a carrier unlock and a bootloader unlock. VZW phones are carrier unlocked and work on any network as long as the radio has the proper frequency support. But VZW phones are bootloader locked, meaning you can't flash unsigned packages to the device i..e. no root yet.
S6 att unlock
hi was it easy to get the att s6 unlocked. Thanks.
Mostly correct except root does not necessarily depend on unlocked bootloader, which you somewhat implied by the end of your statement.
I'm thinking about purchasing a unlocked Sprint Galaxy S6 on craigslist and bringing it to Verizon. Does anyone know if this will work?
Thanks
~Tom
I want the S6 but not if the bootloader is locked. I know that Verizon and ATT are the two carriers who will lock the bootloader. I'm not sure if a T-Mobile line would work due to their using GSM rather than CDMA, but doesn't Sprint use CDMA? Would we be able to purchase a Sprint variant that doesn't have a locked bootloader and then use that phone on Verizon?
Would a Vzw version work on GSM carriers including LTE? I am thinking of buying one off contract for the wife, but want it to be able to go to a cheaper prepaid service later once our contract expires.
t mobile phone on Verizon network
Would the T mobile S6 work with Verizon LTE data only? Did you try to surf the Internet?
Will a Verizon S6 work on T-Mobile? LTE as well?
It should work fine but be aware that VZW uses different LTE bands than TMO. VZW uses Bands 13/4 with 13 as Primary and TMO uses primarily Band 4 but will enable band 12 soon.

Well, when carriers started putting up powers that supported LTE, the phone manufacturers were releasing phones that supported CDMA and LTE because LTE wasn't widespread enough to get an LTE signal. CDMA technology will eventually be replaced by LTE. Qualcomm owns all the parents for CDMA, so whenever anyone makes a call using CDMA, QCOM collects their revenue checks, which used to represent 51% of total revenues. It's cheaper for the carriers to run LTE because QCOM doesn't own the entire technology and they won't have to pay the royalties to QCOM for using their technology (kind of like using H.265 vs VP9 for 4K video compression. Royalties using the older H.265 compression maxed out at $5 million a year. H. 265 maxes out at $25 million vs Google's VP9 free open-source technology for video compression.
Once enough towers are up that support LTE, handsets won't come with the availability to use CDMA technology anymore. Next thing we'll see are cable providers putting up hotspot all around the city (I've already seen it with Comcast, but this could really hurt the phone companies since people won't even be using LTE anymore, just like when people had to use much slower data connections in rural areas on their cell phones because they didn't have towers. VOIP will also hurt the carriers.
So, to answer that, I wouldn't be surprised if they weren't built to support CDMA anymore. These balloons that just started being launched by Google to provide Internet access to everyone in the world will be interesting to see how functional it is. It would be nice top have a high speed connection anywhere in the world.
Sprint and Verizon uses CDMA while AT&T and T-Mobile uses GSM. So trying to use an unlocked S6 for Verizon won't work since unlocked versions are usually GSM. So nope.

I had the exact same problem with my one plus one. I'm 99% certain it's not about the bands being blocked in the phone but about verizon network non-verizon phones. The fact that you can select verizon if you search for a network means the bands are compatible.
Verizon is being evil by blocking the phones. I'm just not sure how (could be that any phone not wishlisted cannot be activated i.e. s13 interface )

Problem is Verizon whitelists all IMEIs for phones that they'll "support." Even if you get it working, it 1) doesn't have CDMA, so you can't make calls unless you're strictly in VoLTE areas, and 2) you won't be able to make any plan changes or get a M2M discount since the phone would be a "Non-VZW Device."

Right, that's been my speculation for a while, but i have no inside info. Whitelisting every device would be a major PITA though...unless they bulk-whitelist then using data from the manufacturers. ..that also doesnt explain why people report being able to bring an iphone 6 or a nexus 6 over from other nwtworks (not sure if rhey have only gotten lte working and not the cdma part)
I do know the cdma functionality wouldn't be available, but tthe discussion was more along the lines of why it attached to lte ans then nothing.
The strange part is that both OP and I saw LTE eveb if for a split second. ..i would expect N attach reject if it's due to the Whitelisting.

The most likely reason is that you did something wrong. I have personally used verizon s3, verizon s4 and htc rezound in tmobile and other gsm networks. (I will test my s6 soon for t-mobile and cricket)
it's well known that most verizon lte phones are unlocked and have gsm functionality.
My most logical guess is that you didn't set up something like the APN.
Your anecdotal experience does not a rule make. (most common fallacy i see in real life: it didnt work for me so it doesnt work!)

Do dual network Phones Exist?

Hello, I currently have Sprint in the USA and locked into a contract but when travelling, the service is spotty. I have to take a 2nd phone that I have with tmobile. I understand I can buy like a new Sprint iphone or the new nexus and just swap sim cards and that will work? That is one option. I was also wondering if there is like a single phone that will work with both sprint and tmobile at the same time. Kinda like the samsung duos phones but those only work with 2 gsm carriers. Tried a search but didnt get anywhere. Thanks. Just weighing my options here.

I was also wondering if there is like a single phone that will work with both sprint and tmobile at the same time. Kinda like the samsung duos phones but those only work with 2 gsm carriers. Tried a search but didnt get anywhere. Thanks. Just weighing my options here.

Not with Sprint. As you've no doubt seen, dual SIM phones aren't exactly common in the US. The few that are are imports, and fewer still will even support North American GSM bands. And of course, Sprint uses CDMA for telephony, and only Sprint phones work on their own network. Your only option would be to switch to AT&T and/or T-Mobile or their MVNOs that work on those networks, and find the rare phone that has LTE for both. But if you're sticking with Sprint, you'll either have to swap SIMs on a device that works with any (as you said, iPhone, Nexus...I think the Moto X Pure does too), or carry a 2nd phone for a different carrier.

Sprint version on verizon ?

Does any one know if a sprint version U11 will work on verizon ? Yes no CDMA compatible with verizon but as published on line verizon no longer requires a phone to have CDMA as per the unlocked version being able to work on verizon and the verizon version itself having no CDMA support either.
I"am asking because I know someone that can get me a discount on a sprint U11 I just need to know if it will work on verizon.
I tried looking up the gsm bands and all I get is one set I cant find any just specific to the sprint version. I know that even if verizon wont activate it I could just pop in a sim that was activated in a verizon phone previously.
Here is a link to an article that lists verizon no longer requires phones to support CDMA to be activated on their network as they are getting rid of CDMA.
