Unlocked model on AT&T, HD Voice - Microsoft Surface Duo Questions & Answers

Still holding off on buying a Duo till the software issues get ironed out but one thing I was wondering if anyone knew is if the unlocked model supports HD Voice on AT&T? AT&T does have a list of non-AT&T branded phones that are supported but it doesn't look like they updated it and they don't support all non-branded phones, just some, however I would much rather the unlocked model over the branded one because of all the bloat AT&T puts in their phones, but I don't want to spend a lot of money on a phone that won't work on the network anymore in less than a year and a half.

I unlocked the AT&T device. How do I test HD voice? Happy to post the outcomes here.

Unfortunately it would need to be an actual unlocked one from Microsoft and not an unlocked AT&T duo as I believe AT&T allows it based off the devices IMEI number, so an unlocked AT&T model should be treated the same as a locked AT&T one as the IMEI number doesn't change when unlocking it.
I'm not positive how to check either unfortunately as I have an older unlocked note 8 so I don't have HD Voice support, looking online some are saying you need an app for it, others say there is a different connection icon when in a call for it, but I have no way of confirming that.

I have an unlocked model on AT&T and it does support HD voice, I get the icon on the dialer. As far as the software the issues are not that bad, more of an annoyance than anything else. Some touch freezes, little stutter from time to time, occasional app close..Beta software pretty much.

Which us cellular android phone?

Hello xda, I was Judy wondering if any of you could help me out with a problem I'm having. I might be getting an android phone, the only problem is that I'm on us cellular and there doesn't appear to be top many options. My phone options are the htc hero s, Motorola electrify, Samsung repp, htc wildfire s, htc merge and huaweii ascend ii ( sorry if I spelled that wrong).
IM looking for a phone with some support of development community behind it, whether it be on xda or some other forum/ website.
Thank you and IM sorry if this its in the wrong forum.

They are CDMA so if may be possible to activate an unlocked Verizon or maybe Sprint phone but you wouldn't get carrier subsidized pricing so it would be more expensive and may be harder to activate.
Motorola doesn't want to unlock bootloaders while HTC has recently made it possible to unlock bootloaders on recent models. Unfortunately the US Cellular versions of any android phone are going to have less dev support because US Cell is a smaller carrier meaning less device owners.

I didn't know that, (sorry I'm a noob at phones). I remember when my dad broke his phone (some cheap thing), my brother's old phone was the same model, os he went into the store and they made it his phone without a problem. Do you think they would be willing to do that if I brought in an unlocked verizon phone?
Thanks for replying.
I'm not for sure if a Verizon phone will work, technology wise it has the hardware to communicate with US Cellular since its CDMA, but it may require some software changes to work on their network. Also it depends if they will activate non carrier devices.

Yeah they probably wouldn't allow it.
Hopefully at least one of these phones has some rom development somewhere on the internet, or I can get the wildfire and just remove sense from it without a problem.

You can go for unlocked phones then. You can get XT910s for just 215$ in ebay.com.
i am not buying phone that is fully working i just want phone with working motherboard so i can change it to mine
Verizon phones are GSM capable for global networks, but not domestic. I think with the proper international firmware, you should be fine. It's got the hardware, but the Verizon software locks out the other domestic networks.

So if i buy this http://www.ebay.com/itm/OEM-Motherb...e_Replacement_Parts_Tools&hash=item3385810018 and install new software i should be fine??
I believe that will do just fine. It's already unlocked, and the description suggests it would work on domestic GSM as well (though I know you're not in the US). That said, it's only 35 USD! Give it a go. You can always turn around a sell it to someone else. As long as you have Finnish firmware and the applicable kernel, I would say your set.

Galaxy S6 Edge- Will I Lose Data Flashing My Phone To AT&T?

Android newb... will I lose anything flashing my unlocked international phone on AT&T
Hi everyone, and thanks for all the great info here. Let's assume I have my "how to root" links bookmarked and ready to go, but like a good boyscout I want to understand the gotchas/subtleties before I cliff jump. I'm also within my 15 days to exchange my s6edge AT&T for an unlocked one at Best Buy, which I plan to do today... :highfive:
(I'm technically savy, but a real newb in the world of android versions, manufacturer changes, and carrier versions and conflicts...) :crying:
1) How do I do a full ROM-level backup before beginning my adventures in rooting? Titanium Backup is no good since I need root to use it. I'd like an iPhone-style backup that I can just restore should I brick my phone.
2) After I exchange my phone I'm going to immediately airplane-mode it to prevent autoupdates (my current phone already autoupdated to unrootable OF4)... once I root how do I effectively get-latest? I'd obviously like the latest security updates, and 5.1 if I can manage it, and to maintain root.
3) AT&T doesn't have 5.1.... but if I go unlocked then can I run 5.1 on AT&T? (I've been iPhone forever -- carriers messing with you is really foreign to me). On a related note, can AT&T send some update/profile-change OTA to my phone that will conflict with updates I'm doing locally? If so any tips to avoid this?
4) An unlocked phone will perform just as well on AT&T as an AT&t phone, right? (looks like the 925F has all the AT&T bands and more, whereas the 925I is missing 1 AT&T LTE band)
Thanks for any info, help, and/or pointing me to resources where I can find the info, in advance. I'm technically savy, but a real newb when it comes to the gotcha-ridden ground of android and carriers.
Thanks again.
- Jason
So can I upgrade a 925F to 5.1 and use it on AT&T? I'm trying to work out if AT&T has _all_ edges locked down or just the official AT&T versions.

At&t does not have the power to lock down all variants; only the variant with its branding. Just make sure 925F is compatible with the network of you want to use that variant.

Thanks so much. Is there a reason I can't to seem to find any people running 5.1 or rooted phones on AT&T? Just that not many people are buying unlocked phones?

The at&t variant is the only variant not to receive 5.1 yet. It has nothing to do with root and everything to do with at&t's corporate policies. Most people who use a smartphone in the USA buy it through their carrier. So those users on at&t likely bought there phone from them. This is why no 5.1 for them.

Will Straighttalk SIM work on unlocked H901?

Hello
I'm with ATT, but I want to switch to StraightTalk, since here in Miami, they use ATT anyways.
I also want to upgrade to the LG V10, but I want to get the T-Mobile variant (H901) since that one can be rooted.
So. Can I buy an H901 from ebay, wherever that is unlocked, and use the StraightTalk SIM on it? I will be able to root it, and get a sim card from StraightTalk that will work with ATT. Right?
Thanks
There should be no issue I have unlocked att phones I have use with t-mobile before might check to see what bands of lte att uses most In your area and check what bands the h901 uses
Buy an already unlocked Tmo phone if you can. If not, still OK, just get it unlocked. I would suggest buying from Amazon over eBay, better quality overall, less like to get ripped off, better sellers. As long as the device itself is fully paid they should unlock it. I've gone through major hassles getting my H901 unlocked, but it's done, as of today.
As far as Straight Talk, it should work. Tmo and ATT are mostly compatible with each other as far as networks are concerned. But check first. They both use SIM cards, so does ST. You should be able to switch pretty easily.
At work, we are affiliated with mywit.com, where we can buy refurbished phones in very good condition.
If I buy a T-Mobile phone that is locked to T-Mobile (as it says in the description), how would I use it on ATT until I decide to switch to StraightTalk?
The switch to Straight Talk involves our 3 phones, so it's something that I have to plan out; one of the phones lives in another city. So, I have to remain with ATT for now. How do I get this H901 to work with ATT? Can I do that somehow?
@nabril15: The answer is simple:
You cant use the phones with ATT or ST until they are unlocked from T-Mo's network. You can use T-Mo's Device Unlock app to get a temp unlock, but that only lasts 30 days. On the other hand, you should theoretically have no issues getting unlocks for all devices involved, if they are paid in full.

And I can get this done by calling TMobile to unlock it even though I am NOT a customer of theirs?

No, t mobile won't unlock it for you if you're not a customer, feel free to try but i doubt they will
Check Swappa, usually on of the best prices and sellers will say if unlocked - also i believe i saw them on eBay for like 250$ unlocked and refurbished
I recently purchased the H901 unlocked from the guys at Mytecell on Swappa. I'm on att. Had to do some research on entering a new APN to get data and MMS to work, but overall satisfied.
Does anyone know if root or which roms will allow wifi calling on att networks?
To my knowledge you can only use WiFi calling on a Tmo-issued phone if you are on Tmo's network. Doesnt matter if you're rooted or what ROM you use, there is probably a server side check. And you generally can only use Tmo wifi-calling on stock based ROMs, no AOSP/CM.

Question Locked AT&T S23U vs Unlocked S23U

Since the Galaxy S6 Edge days I've been getting AT&T branded Samsung phones. This time around due to initial perks of a trade in were better for the unlocked version of S23U, I went ahead and pre-ordered the unlocked version. Are there any drawbacks anyone has experienced with the unlocked version that would warrant me to cancel the order? Are there any AT&T features such as visual voicemail, personal hotspot or HD voice that isn't compatible with the unlocked, non carrier version? Any help would be appreciated as i believe I can still cancel the order.
Thank you.
With an unlocked phone, you cant call. But if you add a sim card into it you can do anything such as mobile data, call, hotspot, etc. An unlocked phone can work on any carrier. But it is still the same thing as an at&t version unless you add the sim card in it.
So I assumed if i insert my AT&T simcard it'll work just like an AT&T phone?

That's what I have done for every phone I have had since the S7 Edge on T-Mobile. Still using the same simcard since I started out with the (S7 Edge), then Note 8, S20U, S22U and now S23U and has worked fine with T-Mobile but without the carrier bloat. The only downside is Unlocked versions always get the updates last.
You can always flash U (carrier firmware) that is bit different from from U1 (factory unlocked) firmware. This way you'll get exactly the same experience as for the phone of any carrier directly. You can always switch back and forth with data wipe.

First time Sammy user here, so possibly a stupid question but... from my search it appears that other than carrier bloatware you don't loose anything by going to U1 firmware and possibly gain faster updates. Is that a correct? Seems to be the case for WiFi calling but what about ATT wifi hotspots for example?
Unlocked phones were useful for sticking local SIMs in them for international travel but with the new international plans pricing is actually reasonable so it is not worth the hassle.

I was in the same situation as you, and ordered the Unlocked version this time instead of the AT&T version. I am happy to report that everything is working. Visual Voicemail (Samsungs App), Personal Hotspot (aka Mobile Hotspot), HD Voice (VoLTE), and WiFi Calling.
