[HTC Vivid, Raider, Velocity] GTTG_Atomik:
After reading the thread, some things to consider. The IMEI on our phones when input into AT&T systems will prompt the rep if it needs a new SIM for LTE. If you have recently went into an AT&T store to swap SIMs prior to you Vivid purchase, then most likely it was changed out for an LTE SIM already.

The bands that are stated in Specs do state that it has HSPA+ and LTE. Remember that HSPA+ is just 3G with Enhanced Backhaul. Meaning if you don't have the Enhanced Backhaul in your area, then it will be normal 3G service.

By changing the APN, you are limiting yourself once LTE is available. Now considering that there are currently only 9 markets, you would want to make sure that you change your APN back to the PTA settings.

My advice is to make sure you are on the correct data package. An easy way to find out is that you should be able to use Visual Voicemail. Visual Voicemail is only available for LTE devices. Not the AT&T Messages, but the actual Visual Voicemail application.

I've been averaging 6-8/.75-1.25 in an HSPA+ area. Talking and surfing working fine.

My wife and I are gonna get this phone next month as our upgrade. After reading this thread on the data connection issue I have one question. Does the connection bug still street it if it is on WiFi only? My wife and I would not be using the mobile network to access the internet, we would surf the internet through WiFi exclusively. If that bug doesn't affect the phone when its on WiFi, then, we will get it. Thank you in advance for anyone who checks.
[HTC Vivid, Raider, Velocity] perryh1:
No issues on wifi for me been rock solid

Koolness, thanks for checking.

Non-LTE zone and this is what I'm getting:

Thats some great HSPA+ Speed man.
[HTC Vivid, Raider, Velocity] ClippinWings:
disregard... i'm an idiot
[HTC Vivid, Raider, Velocity] rquinn19:
You do know EDGE is not 3G

edit: As you said it goes from E (2G) -> 4G (3G) -> 4GLTE (4G)
[HTC Vivid, Raider, Velocity] Noodles5666:
What I originally wrote is just what you posted.

4G LTE=LTE

4G= 3G/HSPA+

and if you don't see 4GLTE/4G that means you are getting GSM/EDGE(which is notated with an E)
[HTC Vivid, Raider, Velocity] ClippinWings:
I read it wrong... LOL
[HTC Vivid, Raider, Velocity] CEaton:
Ok this problem is getting to be unbearable, a website will load up to about 70% then just hang, major ones for me at weather.com 10 day forecast and Facebook. This is when I have full bars HSPA+ I have enhanced backhaul where I live. Soon as I turn on Wifi, everything loads perfectly, this is across multiple browsers... I've tried them all.

I am in Frederick, MD but work in DC, so I am in between LTE and HSPA a lot.

I have not called ATT as it looks like there are a ton of people, especially in this region having the same problem.

My OG Galaxy SII on a different line, same account isn't having any trouble.

2GB tiered plan, completely stock.
[HTC Vivid, Raider, Velocity] malickie:
When you got the new phone did AT&T or where ever you got the phone swap out your old Sim Card? I think that could be part of some of people's issues with this. Other than that I would suggest calling AT&T and see if they have come up with some sort of work around.
[HTC Vivid, Raider, Velocity] ClippinWings:
I have the new LTE SIM and mine doe sit too... sporadically.

It's very odd...

with my phone sitting in the exact same spot, it's horrible, then fine for a while... then horrible..

I'll post up a screen cap in a minute.
[HTC Vivid, Raider, Velocity] ClippinWings:
As you can see its not consistent.... But obviously a problem.

I only decided to run speed test when my connection had been bad for a few minutes...

I find it very odd that my best Ping resulted in my lowest speed.

This was done with "4G" icon, 3 bars, and the phone never moved.
[HTC Vivid, Raider, Velocity] CEaton:
Honestly, I am not sure if they did explicitly put a new LTE sim in my vivid when I bought it, I swapped out another phone from the line to the other line(og galaxy SII) so they may have just popped the sims around, but the sim in my Galaxy is different from the sim in my vivid.

Can someone post up a picture of an LTE sim?

The phone DOES connect to LTE when I am in an LTE area though, got up to 39mbps down in DC on Monday.
[HTC Vivid, Raider, Velocity] ClippinWings:
Neither the Vivid nor Skyrocket connect to LTE without the LTE SIM...

However the Vivid will connect to HSPA+, the Skyrocket will get no data at all.

(Forget where i read that, it was in one of the reviews/comparisons)
[HTC Vivid, Raider, Velocity] CEaton:
The SKU on my sim card does match the LTE sim in this link: http://www.bgr.com/2010/10/21/att-starts-switching-to-lte-compatible-sim-cards/

Looks different, but the sku is the same, so I would imagine I have the proper SIM.

---------- Post added at 06:57 PM ---------- Previous post was at 06:56 PM ----------

That's what I figured, my Vivid does connect to LTE perfectly when within range.
[HTC Vivid, Raider, Velocity] z45123:
Updated Sim

When I went to return my vivid for another vivid I had the sim replaced and the ATT rep even matched up the Sim numbers to the instructions ATT got for the Vivid and Skyrocket and it matched exactly. It seems that ATT is aware the of this problem with both the Vivid and Skyrocket and I was told they were working on this. I have a quick question I have heard that for right now in non lte areas it would be a good idea to enter the HDSPA Apn from my Atrix and for some people this worked has anyone tried just to enter that one APN to use in non lte areas. Thanks

This whole general issue sounds to me like a Network Problem as opposed to Device issue. I mean 2 fairly different devices experiencing the Same problem.
[HTC Vivid, Raider, Velocity] andier:
My Vivid has been bouncing back and forth between 8-13 mbps down (i live in an area with enhanced backhaul) and 1-3 mbps down, or a network timeout. This happens all from the same location, and with 4 bars all the time. I have noticed that on occasion it will drop down to 1 bar and then immediately bounce up to full again. I sent AT&T an e-mail about it, and have yet to get a response. I'm holding off on calling since im sure enough people have already, and i doubt they'll have a magic answer. Figured I would e-mail just so they know its happening at least.

Otherwise a fantastic phone. I'm getting 24 hours between charges easily.

Side note: if anyone knows how to take screenshots on this phone, please remind me :)
[HTC Vivid, Raider, Velocity] dusty2422:
Hold down the Power and Home buttons for a screenshot.

Your getting between 8-13 Mbps down and you're complaining to AT&T why exactly?

I was wondering if some could post the proper APN settings to use until ATT has this figured out. Thanks
[HTC Vivid, Raider, Velocity] Nakel:
Anyone else having problems with Edge? My Vivid is not getting any connectivity at all in edge areas. I didn't realize at first, because I was on the phone before. Since it's edge, I thought it was normal. As it turns out, I can't get any data in anything less than H+. :mad:
[HTC Vivid, Raider, Velocity] andier:
Thanks for the screenshot tip.

I'm complaining to at&t because one moment I get great speed, the next I'm on edge. It's not consistent. I came from a gs2, which had no issues with fluctuating signal or speed. Like the htc a lot better but i need it to actually work consistently when i need to hop on the Internet. When I'm in the lte parts of town it is absolutely amazing though.
[HTC Vivid, Raider, Velocity] tpcastelli:
I put my micro sim in the Vivid and set up a new APN. Using my APN I am getting 4.5 -5.0 down ..no data problems. (Oklahoma City)
[HTC Vivid, Raider, Velocity] CEaton:
Data is just about not working for me this morning, until I rolled into an LTE area(where I work)

Called ATT this time, they don't have any record of other people having issues, so if you are having a problem, call in, let's get this on the books. I am taking the phone into the local corp store to try out my sim in another phone and swap if necessary.

Unfortunately I returned a phone for this already, so I have no choice, I have to stick with the vivid :(
[HTC Vivid, Raider, Velocity] Nakel:
For now, try rebooting. What I found is that if I go from an H+ area to edge, I lose data till I reboot. :mad: I'm not sure if this is a network problem or a phone problem. I'm going to get a Skyrocket for a seperate line and compare the two. I'll keep the better one and return the other.
[HTC Vivid, Raider, Velocity] CEaton:
I've restarted many times.
[HTC Vivid, Raider, Velocity] Dxtra:
The skyrocket is having the same problems. Facebook not loading certain website not fully loading ect ect. Here's what we discover, we suspect at&t has some type of restriction on LTE phones. Try loading Justin.tv it would fail. Is the reason why some website would load %10 and then hangs try another one and it loads. For example try YouTube it would always work .
[HTC Vivid, Raider, Velocity] CEaton:
Just went and swapped out for a new vivid and LTE sim card. Same problems. Me and the rep checked the 4 phones on display, 2 skyrockets and 2 vivids , all were showing the same problems.

This is in Frederick, MD.

Atleast for me its not a throughput issue, when data is working it is faster speedtest wise, its just very inconsistent. A page will fly open about 70% of the way and freeze/byebye data. This is only happening it seems in the Atlantic states, only when on hspa and from the info I've gathered, its worse in the outskirts of an LTE area.
[HTC Vivid, Raider, Velocity] badboy600:
Having the same issue with My Skyrocket in The Baltimore area. Data loads about 70% or not at all. I have to toggle airplane mode for it to start working again. Coming from an iphone 4 this is unbearable. I'll hit the at&t store tomorrow and see what they say
[HTC Vivid, Raider, Velocity] Nakel:
I returned my Vivid and got a Skyrocket because of these problems. As it turns out, the Skyrocket is at least as bad. And no HTC Synch. :mad:
[HTC Vivid, Raider, Velocity] slimslim:
I don't have any of those problems. I don't live in a LTE area, so I just set up the APN values that I had previously on my Atrix, so only HSDPA. No disconnects or freezes, everything works normal.
[HTC Vivid, Raider, Velocity] jpitch2415:
I guess I got lucky, every rep in my att store had a vivid.They changed the apn at time of purchase and I'm getting 6.5 hspa+ and 24 LTE
[HTC Vivid, Raider, Velocity] andier:
Care to share the apn? I'm using the 'phone' apn and hspa works great, but i have to switch it to hop on lte. Be nice if one actually worked consistently with both.

[HTC Vivid, Raider, Velocity] jpitch2415:
I would open a ticket with att and just be patient , I had the same issue with my inspire when hspa+ came around and it didn't take att too long to get it right, because when LTE is rolled out everywhere this phone is thebomb.com
[HTC Vivid, Raider, Velocity] donharden2002:
I don't believe there is a smart phone or any cellphone for that matter that doesn't have a 3g radio in it. If your having issues take it back and don't leave until they have it working properly. Mine wouldn't connect either right after I bought it, went back and another rep fixed it.

It's silly to even think that a cellphone doesn't have a 3g radio.
[HTC Vivid, Raider, Velocity] travisxcore:
Not to beat a dead horse but signals go like this:

2G is Edge

3G is H[spa]

3G+ (which AT&T doesn't show unless you do a reg edit) is H[spa]+

4G is also H[spa]+ but is an updated modem allowing for higher speeds

4G LTE is a whole new protocol.

Remember the cellphone modems are always downwards compatible. 4G LTE phones can pick up the whole spectrum. Besides how can you get H+ but not H. Its the same protocol, H+ is just an updated version.

[HTC Vivid, Raider, Velocity] jayv81:
My data speed in Lafayette, La non LTE. Very impressed with my first test. Others are still good hoping to get more in the 11 range.

One problem i did have was att removed my data package when order was placed. Was not happy as I've had unlimited data since original iPhone and didn't know if I could get it back. But it was their mistake. So they put it back on.
[HTC Vivid, Raider, Velocity] cougmeister:
How do you change the APN?

also, what would be considered average 3g speeds? i live in an area with no 4g or 4g lte

Mine is still not working. Even Google is not loading. (I am in NYC)

Just spent almost an hour on the phone with AT&T. The level 2 support claims that it is not documented as a known issue, but she did see other complaints about this. So what does this mean? She suggested to return the phone...

This was the second time i called them about this. The first time they told me that they had a problem with antenna in my area but now she actually opened a ticket with their advanced team (whatever that means).

That's a surprise because its working for me and I live on Long Island
[HTC Vivid, Raider, Velocity] CEaton:
Looks like maybe the problem was with the region towers and backhauls and the fix is propagating out?

I have been on the phone for no joke a total of about 5 hours on this over the past week. I can confirm without a doubt that I am now working fine at home in Frederick, MD and work in Arlington, VA. LTE and HSPA.

I have an urgent ticket with netops at ATT, they have been calling me every day so far with updates etc, they haven't called yet today, which leads me to believe they may have found the problem and are working to fix it and just don't want to call me until they know for sure, or the fix is spread through the region.

Hang tight.

LTE Faster than WiFi

I have 2 bars of Atlanta LTE out here in the northern suburbs, and am getting 20700-24750 kbps down and 12500-13750 kbps up. This compares to 19400 kbps down and 4000 kbps up on my WiFi connection.

I'd post a screen cap, but not sure how to grab one.
[HTC Vivid, Raider, Velocity] brucegil:
I believe it's press and hold the power button and tap the Home key on the bottom left. Of course, then you have to go find where it's stored.
[HTC Vivid, Raider, Velocity] deepsunn:
Are you in an area that is currently being backhauled? If so, that's probably them taking a tower offline, then booting it back up. I was told by a local AT&T store manager that I might see some issues like that as my area is backhauled...

Also, on the data connection issues, I'm seeing lots of reports elsewhere that the problem has apparently been solved and no one is experiencing anymore issue. Hooray!

I live in bfe outside of Charlotte (which is getting LTE on the 20th) so I imagine that's why.

Experiencing same problem

Hi, n00b here.

I just picked up an HTC Vivid on Thursday, only to find I am having issues with inconsistent data at least twice per day. I live in San Diego, CA and we are not "officially" on the LTE network yet but I have been getting LTE on my phone ever since I picked it up so perhaps it's not quite ready for a formal launch yet.

The strange thing is that in every single instance when my data is inconsistent, I've been able to reboot my phone and it works just fine. I had all but ruled out a network issue because no matter how long I wait/tinker with the settings- a few seconds or an hour- my phone will NOT receive data. But then, I'll reboot it and every time that seems to fix the issue. Seems like more of a handset issue than a network issue, but frankly I'm perplexed.

I'm going to see if AT&T will allow me to replace the handset. I have the grandfathered unlimited data plan.
[HTC Vivid, Raider, Velocity] Jirv311:
Did they give you a new SIM card when you got it? I'm assuming so. My Captivate had an issue like that and after replacing the SIM card it was fine.
[HTC Vivid, Raider, Velocity] QuietLotus:
Thanks for your reply. I did get a new SIM card with the phone. I'll check in with AT&T and we'll see where that goes. Maybe they'll give me a new SIM card as well.

ETA- Just got an email back from an AT&T who said they'd first try replacing the SIM card, then replacing the handset if the issue still persists. Wish me luck...
[HTC Vivid, Raider, Velocity] Nakel:
I had to return my Vivid for the same issue. I picked up a Skyrocket. It has the same issue, but the Skyrocket allows you to use a different APN. HTC has locked out that ability on the Vivid. (A custom ROM would allow you to use a different APN on the Vivid.) The problem with a different APN is that LTE and visual voicemail are disabled. Hopefuly this problem will go away as AT&T fixes their network over the next year. Certain areas do not have this problem already; obviously your area still has the problem.
[HTC Vivid, Raider, Velocity] pside15:
I'm fairly sure this is not true about the Vivid. I never changed my APN before I rooted it but I do remember seeing people using a different APN when their LTE was getting throttled, and that was before HTC unlocked the bootloader.
[HTC Vivid, Raider, Velocity] DUTCH Van Atlanta:
I think you select the option to create a new APN, and then select the new one for use.

Does anyone know if AT&T still plans on enabling 64QAM on their HSPA+ network(if they haven't already)? Or have they decided to ditch evolved HSPA+ in favor of LTE? I love my Galaxy s2, but sucks I can't take advantage of the HSPA+ 21mbps radio, especially considering there will not be LTE here in Detroit anytime soon.
[AT&T Samsung Galaxy S II SGH-I777] milan03:
They are still using 16QAM which effectively limits your speeds at 14.4mbps in theory. The latest I've heard is they will not be upgrading to 64QAM and they expect their users to fall back to 14.4mbps capable HSPA+

Totally sucks that T-Mobile users have been rocking 64QAM since last year.
