Hi all, since a couple of weeks I am the happy owner of an HTC One. Where I live (Belgium), there is currently only one carrier which provides 4G and it is limited to a few cities. However, I live in one of those cities and according to a map on their site I should have 4G reception.
Unfortunately, I tried on several locations in the city and was never able to connect to LTE. My reception is otherwise without problems and I do have 3G connectivity. Now the question is if my phone is the problem or the carrier and a spotty coverage. So I have some questions:
1) Is it possible that the modem is not functioning correctly?
2) Is there any way of telling if the phone is capable of LTE without having an actual network to test it?
3) Do you need a seperate APN for LTE aside from the one used to connect via 3G?
Info for readers that are also living in Belgium. I have Proximus with Generation Connect and live in Ghent. I tested 4G connectivity on "het zuid" and "St. Pietersplein" without any luck.
Not sure if this helps but you could also check with your service provider if the mobile plan you're on allows for LTE access.
Here in Singapore, although there is nationwide LTE coverage, not every customer can automatically access it even though the phone supports LTE. I had to sign a new mobile plan to enable LTE access.
Thx for the reply The situation is very similar in Belgium, not every mobile plan gives you acces to 4G. My plan does, so that cannot be the problem. I suspect it is just spotty coverage by the provider but there is no way of knowing for sure I fear. This afternoon I was standing next to a cell phone tower with network quality -59dBm (which is good I think) and still no LTE. I was getting 24Mbps down on 3G though.
Hmm I would like to know if there are alternative tests too
My area doesn't have lte until beginning next year, but I would absolutely love to see a confirmation that my phone is capable of it

4g and lte are two different things and 24mbs download is 4g or hspa+
I know that 4g and lte are not always the same. 24 down was on hspa+ as you suggested However in Belgium, hspa+ is known as 3g or 3g+ and lte is known as 4g. So in my case, 4g always means lte but I understand your confusion, sorry about that.

You may also need to change your simcard. Here in Malaysia, lots of people buy the phone from retailers, and their older simcard does not support LTE.

That's not strictly true. When the ITU created the ITU-Advanced spec (4G), current implementations of "4G" would probably not pass as it was between 100-1000Mbps. WiMax might. Very few countries went the WiMax route and some have given up sine and switched, most went for LTE as itbwas cheaper to convert existing technology. After the fact, the ITU decided that the 4G term could encompass LTE. So, for over 2 years now, LTE is 4G.

Just wondering if the HTC raider (international version of vivid) will be recognized by ATT's imei database. I'm trying to keep my unlimited medianet plan
No it won't. Using two of them on medianet plans
i would say they probably can, especially if you use more data than say a MEdia Net user would use, that would raise some flags.

For LTE you would need an LTE capable sim card. For 4g youd need a capable 4g sim card, for 3g you'd need a 3g capable sim card. Sim cards are backwards capable but not forwards.

No, its not an LTE capable APN. LTE has a totally seperate RAN and Core network from the 2G/3G RAN and Core Network.
PTA is LTE APN you should be using.
using the MEdia Net plan with the Vivid is like driving a Ferarri with a Yugo engine.

incorrect, you need 4 things:
1. LTE SIM Card
2. LTE Data Plan
3. LTE device
4. LTE network
even if you dont live in an LTE market, you still need 1-3. otherwise you end up changing APN's and not getting a good experience.
Its not a question of if youd gave a good time doing it. I mean if the dude wants to use a medianet plan on a lte phone obviously he dgaf bout having a good time using this thing.
It is possible as asked. No you can't get LTE but yes you can get data.

For LTE you need a LTE SIM
For "4G"(HSPA/HSPA+) you need a 3G SIM... because it's really 3G.
For "4G (UMTS that the vivid calls 4G) you need a 3G SIM
My co-worker bought a Vivid and they did not replace his SIM... his phone worked fine as far as he knew until I asked if he was digging the LTE they had turned on a day earlier... He had no LTE, but was cruising along at HSPA+ speeds just fine... went to the AT&T store, got the right SIM and PRESTO! LTE.
Same SIM he had had since his 3G Blackberry Curve... no way was it a "4G SIM"

AT&T has had 6 revisions of SIM card, as long as you have a SIM card with the digits 25 in 9th/10th place, you have an LTE SIM card, and what i was talking was requirements for LTE, separate RAN and Core network. those 4 things drive the ability for you to be provisioned in the HSS (LTE equivalent of the HLR in the 3g network) you just proved my point above, "got the right SIM and PRESTO! LTE." SIM, IMEI, rate plan drive whether or not you get provisioned in the HSS.
i could go into more detail, however, I'm feeling lazy and tired at the moment.
i am betting they can see what device he has, even if international, AT&T probably has a range of IMEI for the HTC holiday and i am betting it is within that range,
When I got my Atrix 4G they gave me a 4G sim card. 4G is different from 3G(+) It uses the same protocol yes but they upgraded the way the data is handled. As we all know 3G(+) was limited to 7.5mpbs. When I had the Atrix I was getting ~13mbps. There is a difference, and I've seen and researched it. Don't think I would put something in the General Knowledge Thread if I knew nothing about it

the Atrix is a 14.4mbps device. APN you probably were using was Phone, its not as limited like wap.cingular is.
HSDPA devices were 7.2, HSPA+ devices are usually 14.4 or higher
Original "4G" devices:
Inspire: 14.4mbps
Infuse: 21.mps
Atrix: 14.4mbps
Thrill:14.4mbps
does the SIM card have the digits 25 in the 9th and 10th place? they have had 4G sim's out for a while.
You have to have 4G sim to access the APN is what I'm getting at. Just like you have to have an LTE sim to acess the LTE APN. I'm just dumbing it down so someone won't expect changing their APN to work. Now I have an LTE sim, I exchanged phones quite a few times before I stuck with this one.
As for actually data speeds I've gotten -
3G is ~1 (tested on iPhone4, bud hasn't changed his simcard in years)
3G+ is ~5 (tested on LG Quantum)
4G is ~13 (tested on Atrix 2)
4G LTE is ~ 26 (tested on HTC Vivid)

yes, that sounds about right, i dunno where you are man, I've only seen 10mbps down and that was at 2:30 AM. LTE i have averaged that in NYC.
Around the Charlotte, NC area. It really depends on where I am. Some towers give me ~23. Others ~28. I got ~5mps in Concord, NC. Its horrible how much it varies in just a couple of miles.

Yup. I like having AT&T here. We got the backhaul (4G) a month after the Inspire's release. A good 70% of 3G areas don't even have the backhaul implemented yet (hence the reason people stating they switched cards and got no speed difference). This one guy had an inspire was only getting E around here. He got his sim card switched and out of nowhere he got 4G. Its kinda funny how the coverage doesn't overlap like one would imagine.

Hmmm, very interesting, I wouldn't like Charlotte as its a mostly 1900mhz market. Poor building penetration.
I've heard people say that, and honestly I've had no issue what so ever with it. I have never dropped signal inside a building. I do get poor signal in parking garages, and old buildings though, but thats kind of expected. Haha.
Has anyone gotten their z1 LTE working on canada fido?
i've got a 6903, and i swear before i inserted the apn manually i've seen 4g on my status bar. could be just my imagination.
i've tried internet.fido.ca for apn and i'm limited to H+. when i go online and they suggested ltemobile.apn, i couldn't get data at all.

I'm on Rogers, which is the same service and I get 4G using ltemobile.apn. I'm more than happy with this and have been getting 38 mbit on speedtest.
I've not seen the LTE icon tho, and either I cannot get it in this area (which seems unlikely as I am in downtown Vancouver) or this phone will not do LTE as it does not have the 700 band.

I see a 4G icon and have not seen the LTE icon. I've read the manual and it mentions a LTE icon but not a 4G icon, but that's what I have. For all I know I am actually getting LTE.
I had thought that LTE was even faster then this, especially in major cities near antennas.
But from what I have read a lot of LTE users do not even get the speeds I am seeing so I am quite pleased with this phone's data connection as it is.
I am on TELUS and when i originally got the phone it only showed 4G. I have however updated to 534 and it now shows LTE. Hope that helps?

I'm on 534 now. Can I ask what sort of speeds you are getting?
LTE coverage on the Z1 is more spotty though compared to my previous Note 2. Also Telus lacks access to 2600mhz LTE from Bell/Rogers which offers higher speeds.
hey guys, if you are getting anything above 30mbps/download.. especially member 30 Seconds who is getting 48mbps, that's definitely LTE. I just wanted to confirm that you DONT need the 700Mhz to be on LTE. I called Fido on separate occasions due an initial 'not-so-bright' rep who take ages to answer my question and eventually needed to ask her co-worker for help (I don't know how they get hired.. lol) and both Fido employees have stated that ONLY 2100 and 2600 Mhz is needed for LTE. I questioned if support for 700Mhz is needed and they said no. I still am not able to test out my Z1 yet which is still in the box so hopefully somebody can come forward and verify that they see their C6903 showing the LTE symbol on Fido or Rogers.
The frequencies are used differently.
High frequency in urban areas for throughput. Low frequency for less dense areas, more range and penetration. So, what you"need" depends on where you are basically.

I steered away from this for a while after someone told me that AT&T doesn't use band 4 LTE. But I'm hearing isolated reports of people with LTE on straight talk getting 8 to 10 Mbps. I'm all stock right now and just got a new ST sim that works with "tfdata". Anyone care to share how they got it working?

You said you're all stock now. For LTE to work, you need to flash an LTE-capable radio. There are lots of threads that can help you with that, but here's one to start with: http://forum.xda-developers.com/showthread.php?t=2358931 [NOTE: I'm not sure all parts of that guide work with KitKat, so ask someone to make sure.]
Also, are you sure you're in one of the areas where AT&T has band 4 LTE? The easiest way to check is to go here: http://reboot.fcc.gov/spectrumdashboard/searchMap.seam
Click on your state, then filter by name (AT&T) and by license category (AWS-1). If your area doesn't show up there, you're out of luck. If it does, there's a chance, but no guarantee, that you can get LTE service.
I'm on Net10, which is functionally identical to Straight Talk for this kind of thing, and mine instantly worked once I activated a SIM card after LTE service went live. I got speeds as high as 18mbps down, but ping times were around 150 ms, not any better than HSPA. Also, I had issues where the radio would fail to switch back to HSPA sometimes after I left an LTE area, and I would have to go into the phone settings menu to disable LTE data to get it working again. Because of those issues, I haven't had LTE enabled lately, but I'll probably go back because there are areas I go where the HSPA network is too congested to get a usable connection.
Okay Thanx. I just confirmed AT&T doesn't have AWS (frq 1730 - 2135) in my area. However, MetroPCS, Verizon and T-Mobile did. How would you go about going with MetroPCS or Verizon?? I thought they were CDMA carriers.

Has anyone else not be able to use voice and data together?

That's been like since the Evo 4G LTE days.
From s4gru dot com (can't post link for being too much of a noob on this site still)
"In previous Sprint LTE phones, when a device was in Sprint LTE coverage it would park in both the LTE and CDMA Sprint networks at the same time. When a voice call came in, it would just go straight through to the device. And signal to the LTE network would be maintained the whole time while the call was active.
In contrast, a Sprint Triband LTE device can only stay on one technology at a time. CDMA or LTE, not both. So when a Sprint LTE Triband device is in Sprint LTE coverage it parks only in LTE. And doing so means it cannot transmit calls without Circuit Switched Fallback (CSFB) on the network side. CSFB and eCSFB (Enhanced Circuit Switched Fallback) are network controls that will allow a single mode/single path network to operate in two modes, both CDMA and LTE.
Here is how it works in the simplest way I can describe. When your Triband LTE device has an LTE signal, it cannot receive or make calls on its own. It is just using LTE data happily. However, what if someone calls you? How does it get through the CDMA network to your device? Via CSFB.
When the Sprint network tries to forward a call to your device but cannot see it via CDMA, it then checks for an LTE connection to your device. If it sees one, it tells your device to disconnect from LTE for a moment and reconnect to CDMA. Your device then jumps over to take the call on Sprint CDMA and the LTE session is interrupted. This happens very fast and seamlessly. Except for the loss of data availability. If you receive a text, the Sprint network is able to route it to your device via LTE."
This is why I tried to upgrade from the EVO 4G to the EVO 4G LTE recently, I was trying to get a phone that handled LTE and had SVLTE, but it didn't work out reception-wise in my area, so bit the bullet and got the M8, knowing that if I use it for tethering will have to figure out if there is a way to force it to stay in LTE and have phone calls go straight to voice mail.

Thanks for the info. I just came from the HTC Evo 4G LTE. Never had any problems with Simultaneous Voice and Data so I was very surprised when I couldn't talk and use data on this phone. Of course Sprint tech support was useless. They believe it should work just fine.

Yes that's exactly what it means. After discussing this on various forums it seems that no new phones on Sprint will be able to do voice and data simultaneously. The tri-band doesn't all these phones to operate on both the LTE band and the CDMA band at the same time. I'm trying to decide now if I'm going to return my M8 and switch to T-Mobile. Then purchase it from them.
this may be a deal breaker for me as well. i have been paying for wimax wifi untill lte deployed in my area... that the phone i want wont allow the vlte is very disapointing.
I thought I heard a while ago that is a thing of the past. GS3 (and apparently the Evo 4G lte) was the last to be able to do that. They removed that feature from the S4, and any device from that point on iirc. Not 100% on all that, but I know I read something like that before.
Never investigated as to why, but the only thing I can think of would be for safety reasons. Its bad enough that people text and drive, and I can just imagine how many would be driving, on the phone, and texting, or trying to browse the web.
Certainly a feature I will miss though, coming from an S3. Neither my wife nor mom want to upgrade because they don't want to lose that capability.

Fair enough. I wasn't 100% sure, I just remember seeing somewhere that they were doing away with that capability at some point. It's stupid though either way. There's been plenty of times while talking about something on the phone where I've said "hold on, I'll Google it", or had the other person send me a picture of something. Will miss that feature.

For clarity, please confirm is my understanding is true: this issue will be fixed in time, but we just don't know when - and Sprint is being shady about it.
I am an AT&T customer on the old Skyrocket. Long overdue for an upgrade, and I've been leaning toward switching to Sprint and getting the m8 ('real' unlimited data is a major factor). Now I'm weighing this issue, deciding whether it's significant enough to not make the switch after all.

No, this is not really an “issue” since it’s not a feature that’s performing improperly. SVDO and SVLTE (being able to hold a call while on 3G or LTE, respectively) is simply not possible due to the new antenna design.
On the EVO 4G LTE, SVDO and SVLTE were both possible, but that phone wasn’t the greatest RF performer. On the One M7, SVLTE was still possible, but SVDO was removed to help offset RF fade so that the signal could be improved. I suspect that the antenna design was changed again on the M8 to further increase performance, but at the cost of only being able to do voice OR data at any given time. Also, there appears to be a network limitation with tri-band LTE devices. See the post from rhe12:

Apparently in a theoretical future, when Sprint rolls out voice over LTE, this issue would, well, not be an issue anymore.
"Schlageter said the tri-mode LTE smartphones will be able to handle simultaneous voice and LTE data when Sprint deploys Voice over LTE. She noted Sprint has not yet set a timetable for when that will happen."

Thanks for the replies. Seems like a usability oversight (or just bad decision) to me. Are other carriers able to support SVLTE or SVDO on Triband LTE devices or is this a device constraint?
Thinking about it, I only occasionally use data and voice at the same time so this might be more of a minor irritation to me. I have a question for those you who have experience with this - Is there any noticeable lag when CSFB occurs for either user (caller/receiver)?
Also, the language in the spokeswoman's replies in that article is frustrating.

I wouldn’t say it’s an “oversight,” either. I would say it’s more of a limitation of the compromise between RF performance and features. Sprint’s M8 variant will have access to more LTE bands in more areas than any of the other carriers. I could be wrong, but I suspect that the trade-off for SVLTE has something to do with the fact that the Sprint M8 will be switching between LTE bands more often than other carriers’ variants. Let’s take a look:
For the One M8, these are the LTE frequencies that each carrier-specific phone has the radio/antenna for:
AT&T: 700/850/AWS/1800/1900/2600 MHz
Sprint: FDD 800/1900 MHz , TDD 2600 MHz
Verizon: 700/AWS/1800/2600 MHz
TMUS: 700/AWS MHz

As it currently stands, these are the LTE frequencies the above carriers have deployed or will soon deploy:
AT&T: 700/AWS/1900/2300 MHz
Sprint: 800/1900/2500 (2600) MHz
Verizon: 700/AWS MHz
TMUS: 700/AWS/1900 MHz

This means that only the AT&T and Sprint versions can use 3 LTE bands on their respective networks. However, since only Sprint will have all 3 bands available nationwide, I suspect that there might be something network-related which would allow the AT&T model to still allow SVLTE, but again, I could be wrong. I think I’ll take this to S4GRU.com to fact-check.
So without thinking I bought a Nokia Lumia 920 for AT&T off of Ebay.
Now after doing some research I see I may not be able to get 3G/4G.
So I have two things to ask, would flashing another rom on my device help? (I really don't think it will but i'm going to ask to be safe)
Or is there anyway to get 3G/4G working without having to buy a new phone -_-
T-Mobile obtained a bunch of bandwidth that AT&T was going to use, after the failed acquisition attempt. They've used that to roll out network coverage for AT&T's phones, as part of their plan to encourage people to switch. It's not as *extensive* of coverage as T-Mobile's native bands, but it's not terrible. You probably can't get LTE, but you can get 3G and HSPA+ (what TMoUS often calls 4G, especially before they had their own LTE).
I know I get 4G and LTE on T-Mobile using an AT&T 920, but I think LTE only works in certain refarmed areas that use the right frequency. HSPA+ (4G) and 3G appear every once in while and work as well.

I can deal with that, I know back in the day when i unlocked my wife's Iphone 4 it could only get edge. but I was not sure if that problem was just because well it was an Iphone.

sweet thanks for the info.
Yeah, old iPhones used AT&T's frequencies for 3G and T-Mobile uses different frequencies, so you couldn't use 3G. That's not much of a problem anymore, though; even phones that don't support T-Mobile's main bands can use their re-farmed AT&T bandwidth.

T-Mobile refers to it as refarming; that is assuming you have coverage and that's a big if for many of us who are rural and you live in a town big enough to have it then if you're using an AT&T device subsidy unlocked or locked then you will be able to access HSPA+ and I'm not kidding when I say it's fast, faster than both AT&T and Verizon Wireless in Auburn-Opelika, AL and Columbus, GA where I hail from. HSPA+ is not a LTE or 4G technology so it will run on both AT&T and T-Mobile's 1900 band...if AT&T it's HSPA+ everywhere and where T-Mobile has refarmed 1900; it's 3G or 3.5G there too. Otherwise, it's 2G and I can safely tell you it sucks once you've enjoyed HSPA+ and worse T-Mobile has next to no coverage in many places outside most big cities and that's the wrap with T-Mobile.
