[Q] 64GB unlocked developers HTC One. I have questions..

Hi all,
I'm about 90% sure that I'm going to buy the 64gb dev. HTC One. I'm still on Sprint but I think I'm done with them as they have seriously lost my confidence.
I don't have any experience with an unlocked phone that require a sim card and I'm kind of intimidated by that but I want to learn and see what kind of experience I have with an unlocked phone. I don't know how the whole sim card thing works and how it relates to Tmobile or At&t services, radio frequencies, 4glte, hspa+ etc.
I'm thinking of buying 2. One (no pun intended) for me and one for the wife. I guess my question is how do I make the transition from Sprint to Tmobile as quickly as and painless as possible. How do i explain an unlocked phone to my wife who also never been on another carrier other than sprint? What plan should I consider on Tmobile and or At&t. Which carrier's network is faster (I'm in Central NJ).
I understand the dev version has an unlocked bootloader. Does this mean it comes installed with a recovery and is it s-off / s-on?
I'm not a geek but I know how to flash roms/ kernels...basic sh*t you know.
If anyone can school me on what to expect form an unlocked phone and what I can do with it would be great. Will I be able to use sim cards from both tmobile and at&t on this phone?
Any help would be appreciated...

IIRC the Dev unit does not work on Sprint so you'd need to switch regardless.
You'll just have to get a new account and have them port the numbers over but you just won't be buying a phone on contract.
Most think it will have S-ON, but bootloader unlocked. This just means you can load ROMs, but they are locked to the kernel from HTC (not just any kernel which would be nice if you had S-OFF).
Yes, you can use a SIM from ATT and T-MO but remember that with T-MO unless you live in a new LTE zone or a refarmed 1900mhz HSPA+ band, you will be stuck with 2G speed.

The SIM cards will be given to you by T-MO or ATT when you sign up.

no problem, glad I could help
just go to T-MO or ATT store and tell them you have your own phone and simply want x-plan (whatever it is you're looking for)
obviously T-MO is nice for pre-paid, no contract, but unless you live in a new 1900mhz zone (or LTE) and the phone could possibly be flashed with t-mo's firmware (possibly opening up 1700) then stick with ATT

I just checked the refarmed 1900mhz map and I'm real close to i guess two towers. There's a **** load of them a few miles from me, but none at my address. Do you think I'll be able to pick up on that 1900mhz signal?

Wow, just checked all the area's where I usually go, NY (family), CT (work) and the 1900mhz is excellent except for where I live which is scattered but not that far away.
By they way, I just purchased 2 HTC One's. One for me and one for the wife! However, there on back order until they get there next shipment which they say is on the 24th of April. I'll keep you posted.

How close? If you're decently close to two towers you should be fine. To port your number from Sprint you will need to check four things,
1: Your account number. (Dial *2 for Sprint customer service from your Sprint phone for that)
2: Your account pin. (6-10 numbers)
3: If you have any time left on your Sprint contract. Keep in mind you most likely signed a 24 month contract, but upgrades roll around every 20 months. So even if you're elegible for upgrade there may still a early term fee from Sprint.
4 Basic information such as the main account holders name, billing address, etc.
Keep in mind that at the moment the 32 and 64gb versions are out of stock from HTC (for now) If you start up a new account on T-Mobile with unlocked devices you will be on what's called Month to Month pricing. This means that since you provided your own equipment, you will be able to cancel at any time with no termination fee. You will also have upgrades avalible from the get go since you didn't purchase subsidised equipment from them.
Good luck!

Wow, this is great information. From what I can see on the coverage maps the coverage is excellent. I just purchased 2 HTC One phones. However, as you said there out of stock and I'm on back order. I talked to representative and they said there next shipment of phones are not coming until the 24th of this month. Also. are the dev phones gsm phones as well?

Fantastic! Yes, the Developer Edition is factory unlocked GSM There are two types of phone radios CDMA (Verizon, Sprint, Boost, etc) And GSM (At&t, T-Mobile, and basically every other international carrier) A locked phone is basically a phone configured to only accept a certain carriers network baseband. Unlocked is, well.. Unlocked! :laugh:

I'm so amped, can't wait!!!
Ok, the boot loader is unlocked but will i be able to achieve s-off on this bad boy. I have a EVO 4G LTE rooted s-off phone now but how does that work with unlocked phones? Also, you mentioned updates. Will they come straight from Google like they do on the nexus phone?

I don't think anyone has been able to get s-off this early, and if so it'd require access to a PC to use fastboot commands. Once more developers get their hands on one, it'll (hopefully) be a somewhat painless process. As far as updates go it will most likely be in the same boat as the carrier versions. One more reason having the a rooted dev version would be the bomb.com.

T-Mobile Moto x question - activation

I know that tmobile moto x is not carrier/sim locked, read it in many threads here.
But does it need to be activated with tmobile sim first time?

T-Mobile Networks
Well, I hope it's true that the T-Mobile comes with the Sim unlocked... I think I'll buy it tomorrow with the promotion of the cyber-monday extension.
But I'm a little worried about the T-mobile version network support, you see, most people, including me, of my country buy Unlocked ATT variants from the US, because here we only have these networks:
850 - Movistar / C&W Panama
1900 - Claro
1800/1900 - Digicel
I'm with Claro so I'll need 1900.
Since most of the ATT variants work with those bands, people over here buy those... While T-Mobile variants don't. But now I'm seeing that the Moto X from T-Mobile supports four 2G GSM bands (850/900/1800/1900) and comes with five UMTS bands (850/900/1700/1900/2100).
I'm not checking the LTE capabilities, since my country hasn't implemented it yet, and when they will, I'll probably won't use it after some years ($$$).
So, does this phone really works for me? I thought of buying an ATT variant but it seems some persons here (xda community) had problems unlocking the sim... (I don't mind paying to get it unlocked) One even posted that couldn't unlocked, used all the tries and had to put it on sale trough eBay :crying:
Well, what do you guys think of this...? Really, really crossing my fingers here :fingers-crossed: (Just checking the bands here, not much interested on rooting the phone, actually scared too. Don't wan't to hard brick anything )

If the T-Mo one supports the bands you need then why roll the dice with the AT&T version? If you really want the AT&T version and AT&T won't unlock it for you then you can just return it. If you want to get in on the sale price and don't want to risk anything then buy one of each so at least you will have the T-Mo one to fall back on. Just some suggestions. I am not really familiar with bands and sim unlocking and how it's done.

Oh, just wanted to be extra sure that this version will work with the bands available here at Panama... Guess there's nothing weird with that variant of the Moto X having 5 UMTS bands instead of 4 like the others.
Anyway, I'll post my feedback later when I buy and get the product, wish me luck and thanks :victory:

Guys... look at this thread
http://forum.xda-developers.com/showthread.php?t=2546466&highlight=sim+network+unlock
From what the whole thread states the tmobile version is sim unlocked out of the box even through moto maker. In fact they are stating that there is little difference between the tmobile and dev edition.
So from the whole thread there I will pruchase tmobile. Verizon is unlocked but does not have the correct radios for my countries 3g network. Att does but I do not want to have to go through the hastle of unlocking it... even if its simple to buy a code.

Also go to the companies and ask what bands they work with expecially the 3g and 4g. I know first hand that Verizon does not support most of the bands in central america... Ive had verizon phones here and they only get 2g sometimes. And good luck with going to the companies... most people there have no idea... and they will stare at you with a blank look on their face when you ask about bands and will probably try to sell you a phone. So be patient.
Also... keep us updated!!

I have an Claro Chile phone using tmobile kit kat and works 2g, 3g, h/h+, 4g LTE bands without any issies

Hey, Just the thread i needed !!!
Off the research so far,
Droid 4(XT894) is a CDMA Device whose ESN is attached/programmed to a verizon mobile number ... right ?
Within the US this device does not support/accomodate a GSM SIM card ... right ?
While outside US, Verizon number works on international roaming.
meaning Calls and text(does internaltional verizon data work too) work on this phone while travelling internationally just fine ... right ?
While travelling outside US, one could load a Local GSM SIM card and this will enable this phone to work like just any other GSM phone ... right ?
Here's where my question's lie ...
When a GSM SIM card is loaded outside US what happens to the pre-programmed Verizon Number which was working on roaming ?
Does the verizon number work alongside the international GSM SIM card ?
Do calls to the Verizon Roaming number and the local GSM SIM number both work together ?
If so ... can one use Verizon Roaming number for calls, and the local GSM SIM for internet data ? ... simultaneously ?
Will it be the same like a dual-sim phone where both numbers work simultaneously ?
;
;
;
Is it true that this phone supports even a CDMA SIM Card on its SIM slot ?
thanks for reading and any info is greatly appreciated.

Really all verizon uses is the sim card, I have pulled my sim card out and used it with my XT908, XT894, and XT907 without ever contacting verizon about the change, and call, text, LTE all work fine.
The XT894 can only be connected to either cdma or gms not both.
It will not work with other USA carriers
If using outside of the USA, gms will work but suggest installing the gms patch, for improved compatibility.

thanks for the quick reply @sd_shadow ...
So that confirms that the SIM slot reads both GSM and CDMA SIM modules.
I still have a feeling that Verizon (i could be wrong, hence the question) programs these phones to work based on their ESN No. else why would people on ebay sell phones with 'CLEAN ESN' ... If a verizon CDMA SIM can work out of this phone why does one need a clean ESN, I thought clean ESN's are used to program CDMA mobile nos. through them !
Anybody here running a Droid 4 (XT894) without a verizon CDMA SIM just fine ?
OR
Droid 4 (XT894) runs only through a Verizon CDMA SIM unlike its non SIM based older cousins ?

ESN is old technology, and hasn't been used for some time.
What are ESN, MEID, and IMEI (device identifiers)?
Every device has a MEID and/or a IMEI which is used along with the sim.
Verizon will blacklist a device if it is reported stolen or you don't pay your bill.
Lots of people are using the Droid 4 outside of the USA, but only with GSM/3g
LTE only works with Verizon.
The Droid 4 will not work without a sim card, GSM nor LTE/CDMA.

@sd_shadow ... appreciate the quick response and the clarification.
I read somewhere that Droid 4 can be registered with other CDMA operators outside USA only with an ESN Number, hence my question ... if that is another way to program a device with a mobile number to run without a CDMA SIM.
With regard to LTE ... If any country has a LTE network running on a frequency(700 MHz) similar to that of Verizon, then may be this phone's LTE might work ?
Probably my original question would seem relevant to a ... GSM-SIM-SLOT-modded ... Motorola Photon Q LTE (XT897) ... as that is a device which works as a programmed phone and there is no SIM Card Slot for CDMA SIM either (or has it got one ?) !!!
Any ways thanks for the information !!!

The Droid 4 can be manually programmed via DFS CDMA Tool, but only through the stock boot process and ROM. You would have to adapt the process a bit for a foreign carrier, of course, and getting the needed info might be slightly harder.
After being manually programmed, and if Mobile Networks > Subscription Type is set to NV-only, it can be used just like an older 3g-only phone: data works, SMS/MMS works, etc. You DO need a SIM card installed in LP, though, or it constantly complains about the SIM missing and stock SMS won't send messages. Certain KK ROMS (SlimKat for instance) don't need a SIM card installed at all. Whether the SIM is old or new, active or not, etc shouldn't matter.
Assuming you get through all that, you'd also need a carrier who is willing to add your IMEI to the network to "activate" the phone. As far as I know, no Verizon-based MVNOs do this after the beginning of this year (PagePlus was probably the last, they finally stopped after Verizon started double-charging for each activation), but I'd imagine carriers outside of the US would have less of a problem with it. Again, getting the needed information to program by hand might be difficult, and the phone can't be automatically programmed OTA.
Best way I can think of to get said information would be to get a natively 3G phone, have it programmed OTA, then access it with DFS or the like to see what the programming is like. Copy the parameters to the Droid, have service transferred to its IMEI, bam, in theory you have 3g service.
While there might be other carriers using the 700mhz LTE band, depending on how standardized LTE is or isn't, they might not be using it in the exact same way as Verizon. It's certainly possible that it would work perfectly fine, but I wouldn't bet money on it.

The Droid 4 can be manually programmed via DFS CDMA Tool, but only through the stock boot process and ROM. You would have to adapt the process a bit for a foreign carrier, of course, and getting the needed info might be slightly harder.
After being manually programmed, and if Mobile Networks > Subscription Type is set to NV-only, it can be used just like an older 3g-only phone: data works, SMS/MMS works, etc. You DO need a SIM card installed in LP, though, or it constantly complains about the SIM missing and stock SMS won't send messages.

thanks @Septfox ...
So if One was using SLIMCAT ROM and somehow programmed the phone to say a CDMA operator(the way you've described), say in India(from where i am) ... then without a CDMA SIM card this phone's Call, SMS & Data(3G) should work just fine ?
During such an instance if i load a GSM SIM of another operator what would be the situation ?
I am just looking at using CDMA for Call & SMS(would be good too if Data worked) ... And from my GSM SIM i would like to use only the Data !
So what are the chances of that ?

In theory, yes. As long as the channels match up, CDMA service is pretty standard as far as I know. And to be as clear as possible: you can use any ROM, if you have an LTE SIM card installed. The SIM doesn't need to be active, as it isn't actually used if the phone is manually programmed, it is simply there to make the phone stop complaining about a missing SIM.
To reiterate though, this is all in theory. As @sd_shadow said, to use 3G CDMA outside of the US, you might want to find a phone that does it natively. The Droid 4 was intended for 4G LTE/voice over CDMA in the US, and GSM internationally. Trying to get it working on a non-Verizon CDMA carrier should be done as a curiosity, not out of expectation that it will work.
As for non-Verizon carriers in the US, there are at least a couple; Boost and Sprint come to mind. Verizon is the primary CDMA operator here, most other carriers claiming CDMA service are actually MVNOs (Mobile Virtual Network Operator) who "rent" capacity on Verizon's network and resell it to customers as prepaid packages. Verizon MVNOs will refuse to activate the Droid 4 for 3G-only service, as its IMEI immediately gives it away as a 4G LTE device. Boost and Sprint probably won't care, so long as the phone operates on the same channels, but they also won't offer any assistance in programming a phone if it can't be done OTA.
Wherever you are, you would probably have an easier time finding a GSM carrier, since all of the needed information is on the SIM card. There are a lot more "ifs" and "maybes" when it comes to CDMA when it can't be automatically programmed, unfortunately. That said, if you have a particular carrier in mind, it may be worth looking around the internet to see if anyone else has tried to program this phone or the RAZR (which apparently has a similar radio); it might turn out they've already gathered all the necessary information, and it's a matter of entering it all into your phone. Finding information for Sprint and Boost should be easy; carriers outside the US might be a bit more difficult.
Lastly, it's worth pointing out that the Photon Q is a physically similar CDMA phone with technically superior specs, already on the Sprint network. It lacks a SIM slot, though, without some delicate modifications to the mainboard and case, so it can't be as readily moved to GSM service. It's also not as well-supported here (at least, the last I checked) as the Droid 4, so its ROMs might still have some outstanding bugs.
Also like sd_shadow, you can't use CDMA and GSM service at the same time. Stock and most AOSP-based ROMS are configured for Verizon 4G/CDMA service by default, and have to be patched to change over to GSM; this necessarily disables some CDMA functionality. To undo the patch, you have to reflash the ROM (or replace the files that the patch changes, if you backed them up).

MI5 - Can I Bring It to VZW In The US?

Hi Everyone,
I've been reading the reviews and specs for the MI5 Pro and am considering purchasing one. GSM/CDMA support, 128Gb Storage, etc. sounds great to me.
My plan is to have something with an unlocked BL so I can root, TWRP, and AOSP it just the way I want it.
Before I do how much of a pain will it be to getting working on Verizon's 4G/LTE networks? If I understand what I am reading correctly it supports all the frequency bands on Big Red. Any thoughts? Comments and suggestions are requested on this.
Thanks in Advance

I should also add this is not for the BYOD (Bring Your Own Device) program. I have a monthly plan and am up for a new device but don't want what they offer.

I highly doubt you'll be able to get it to work on Verizon. Even unlocking GSM bands is a pain.

VZW is CDMA. The specs say it supports all the needed bands I just don't know if they are "active" out of the box.

I don't specifically know about verizon, but our local CDMA carriers do work with the Mi5.

Cdma carriers the us only allows approved devices.
No hope.

You can be the guniea pig and try it out but your chances of getting it to work on Verizon are slim to none.

The more I research this the more dim the results look. It seems that the problem with bringing it to a CDMA network is lack of 4G functionality. Definitely a deal breaker for sure......

Verizon only allows approved devices on their network (read: their branded devices). So there's pretty much no chance of your Mi5 (an unapproved, semi-compatible, and untested device as far as they are concerned) getting on the network, as your MEID needs to be in their system for you to connect to their network.
Stick with an actual GSM carrier.

I knew that was how they were in the past but I thought maybe they loosened up on it. They now have a Bring Your Own Device program. Still doesn't get past getting 4G working flawlessly on CDMA.
I need to look deeper at GSM carriers in the US. Coverage in my area is important for work.

I just saw you message and it is a bit late, but I have the Mi5 and use it on Verizon. It is only 3G on that. I can also use both my Verizon Sim card and my AT&T sim at the same time and have two carriers with two different numbers on the same phone. I had to do nothing to get it to work on Verizon other than pop in the sim card. I hope this helps.

Thanks DFSPCC, I was wondering the same thing and having it listed to work with VZN in the US on willmyphonework.net up to 3G speeds, which is fine by me. Considering the low price at the moment for the Mi5, I think is a great option.

Never to late
I'm considering on getting this phone... 5.7 inch with OK specs to work with Verizon only thing is you said 3g but that's OK its just to play and test hopefully I can root it... Don't knkw if they have any Roms for it..... Ive been HTC for over 10 yrs and they have let me down been waiting for a 5.7 or bigger... The max was nice but bad specs realy slow so.... I was going to do the s8 plus but now I see the U12 coming soon. But i don't know if Verizon will carry it... They don't carry the U11 don't know why.... What do you think? And thanks again for your time and help god bless....

H speed on ATT

So here's my question. I'm considering the OnePlus 3T. I ordered the OnePlus 3 from Amazon to give it a test drive (and have since returned it). I noticed that most of the I was getting H speed on ATT.
Every other phone I've got (Moto X Pure) and Axon 7 (as well as my prior Nexus 6p) was regularly getting 4G or LTE in the same locations.
I'm assuming it's reasonable to assume this is a OnePlus issue.
Has anyone who has the 3T (or considering it) has a similar problem? Thanks.

I assume you're in the US? You might've gotten a phone built for another market, such as China. Also, your APN settings might've been wrong... I'm getting mostly 4G/4G+ on my 3T, which I believe is LTE on OxygenOS. I may swing by my local AT&T store to verify my SIM is a-okay.

Most of the resellers on Amazon/eBay buy devices from the Chinese market which, for the most part, have bands that are unsupported by US carriers. If you buy the correct model for the US, you should get good signal on ATT.

False. Read the T-Mobile LTE thread. The issue is software based. It's affecting everyone.

I'm having no false read issues here in Seattle Region on T-Mobile. I also had someone attempt an AT&T SIM as well, no problems. It may have something to do with the "General Fixes" mentioned for 3.5.3.

I've got my OP3T on AT&T and on OxygenOS, it never shows an LTE icon. However, using LTE Discovery, it states I'm on LTE. I even get LTE B30 (2300 WCS) at work while my OP2 could barely keep a cellular connection. B30 is an LTE band that AT&T rolled out a year ago. Only a handful of phones support it, including the OP3 and OP3T.

EDIT: I'm seeing performance equal to or better than my previous phone.
Most importantly I don't have a good baseline to compare to so take this as an extra small grain of salt.
I thought things were fine but upon further investigation my speeds will not keep steady over 10mbs down. I haven't tried changing the apn or anything to correct it yet but according based on others I'm thinking it's software related and can hopefully be sorted out. I'm not giving up on it, for the cost, features, and quality of everything else I'm going to try some things.
I should mention I'm not in a city and my particular area hasn't always had the best speeds.

Using OP3T on AT&T
Never owning a OPO device I wondered about this too when I got my OP3T. I didn't know if this device had to show LTE to get LTE.
I didn't have any issues with data speeds but after reading about other people questioning this on the forums I decided to look into it. I downloaded an app and it showed my device was getting LTE even though it didn't say it up top (it shows 4G). I forgot what band it said I was getting. I didn't call AT&T at any time either.
*The speed test is from indoors and I wouldn't be surprised if I can get way better speeds out and about.

That thread refers to an issue that has been determined to be T-Mobile specific, likely to do with carrier aggregation and/or band 12 exclusively. AT&T does not use band 12, and CA works perfectly on AT&T including, as another poster mentioned below, band 30 which only is supported on a few phones.

The current version of OOS on the 3T doesn't use the "LTE" label, it uses 4G to denote LTE, and 4G+ for LTE CA.

If you read the T-Mobile threads (one here and one on OnePlus forum) , then you'll see that the T-Mobile issue is only a T-Mobile issue. I'm in that thread just to double-check that the fix they made for the T-Mobile problem didn't screw up anything on other carriers and it didn't. It's not affecting everyone, but it was affecting some T-Mobile users, not ATT.
Also, a lot of people seem more upset by symbology (which icon LTE, 4G, 4G+, etc) is used than their actual speeds. I'm not seeing what difference that makes unless you'd rather have a certain icon than speed. No doubt that's a simple fix or even an xposed type of fix.
Oh yeah: I should've also mentioned that I'm an att 3t user with LTE speeds about double that of my prior phone, a galaxy (a current one). I'm in a fringe area but getting ~20Mbps down, 5-15 up. My "icon" constantly is switching from 4g to 4g+.

Huh? It's not affecting ATT users in the USA.

I can confirm it is affecting AT&T users as well - there have been many reported instances on this site, on the OnePlus forums, on Reddit, and on other sites of not being able to get LTE on AT&T. Last week, I chatted with AT&T tech support and they told me the issue is on their end with the network. They need to add the IMEI ranges for our OP3Ts to their database. They told me that they should have the problem fixed by December 5th (today); so far it doesn't seem fixed yet but I'm going to keep waiting another day or two before I contact them again.

Yes, but you can actually reply in complete sentences so I have to take you more seriously . ;
I somehow managed to post that before I'd really typed anything (which might have been a good idea damnit!). Anyway: I think that some of us (almost regardless of carrier) have just popped in our known good SIM cards and then had trouble free service , and fast speeds. It's possible that if I had went over to ATT and gotten a new SIM, that I'd be in some hellhole range of people that are having problems, but isn't that a carrier based problem?
Anyway, thanks.

Exactly. There are two different issues. The T-Mobile band 12/CA issue, which OnePlus is addressing via a software update of some sort, and the AT&T provisioning issue, which AT&T needs to address. Consensus is that if you use an already LTE provisioned SIM card you'll be fine; if you need a new SIM card and give them your OnePlus IMEI, you will not be provisioned with LTE. This is the same issue that the original OnePlus (and many other non AT&T unlocked phones) had, there is a very lengthy thread on this subject over at the OP3 forum.
Also, with regards to 4G not getting LTE speeds...the "4G" and "4G+" icons on 3.5.3 on the 3T are LTE.

i second this. i too had to change my sim card from micro to nano and after that is where i lost my LTE i believe. On att i only get H speeds, though i am a bit bothered for lack of highspeeds the reception service on my OP3T is excellent, i almost always have near full bars.
I read somewhere that after the 5th (today) ATT will correct some of the provisions for the OP3T, so im waiting till tomorrow to call them again to complain about the issue, if it doesn't correct itself.
