HELP | Unable to use Cingular UMTS network in the Washington DC area

Guys
I am trying to setup my new TyTN to use Cingular 3G/UMTS .. but for some reason .. it doesnt work .. which is a really breaking my heart because as per the 3G coverage map from Cingular my area (Dulles airport/Reston) has 3G coverage.
The details/settings are:
Device: Stock TyTN, HERM200, HT636 series
SIM: around 2 years old, 64K SIM (no 3G indications on it though)
ROMs: Original HTC ROM (07/22), 1.16 RadioROM (Updated)
Bands: Auto, Auto
After soft-resetting with these settings, when the device comes back up, it shows the fabled "U", but then immediately the signal drops to zero and I am not able use voice or data.
TyTN only works when I set it to GSM, GSM (1900+850) + UMTS(1900+850) band settings, which gets me on the GMS network and gives me Edge speeds only (~130-140K). The signal strength is pretty good (3 to 4 bars)
Any thoughts regarding what might be going?
Thanks in advance for the help!!

I thought that you needed a 3g sim card? I could be wrong but i thought i seen that somewhere.

If you do get it working I would love to know how it works. Im doing alot of reading on the Herms as it will be the wifes Christmas present.

My TyTN to worked just fine during a recent trip in your exact area. Try this:
Drive to Dulles Airport itself and check if you get 3G inside. 3G coverage was excellent there but got spotty for me a mere 5 miles away at the Dulles Airport Hilton.
If you don't get coverage inside the Airport, go to a Cingular store and request a 3G SIM upgrade. They say "3G" right on the back.

:O I thought I had a 3G sim, but I have a regular 64k sim! I now have to go to my local store to pick one up!

Hey guys....I live in Northern VA and just got a TyTn last week. I setup my GPRS connection using the Cingular settings and left the bands on Auto. I get excellent 3G reception (before and after 1.20 radio upgrade). You probably need to go get a 3G sim card I guess. I thought my card wasn't 3G but when I checked closely it indeed was. Just out of curiousity I called my local corp store and they told me you can just go in and they'll give you a new card.

Right, there's not supposed to be a charge but my local Cingular store fleeced me for $20...
Had I known then what I know now I'd have questioned it...

What do you know now? I don't wanna pay $20 for that! lol

That Cingular does these for free. I'd ask "ummm... how come you charge $20 for something your company authorizes you to do for n/c?"

Well it was the SIM card!! The guys at the store charged me 25$ for a new SIM ...
but ITSSSSSSSS WORKINGGGGGGGGGGG now ... WHOHhhhhhhhhhohhhhhhh
getting over 900kbps on my TyTN !!! Thanks Sleuth!! YOU ROCK!!!!......

jeez.... those fleecing bast!rds.... must be lining their own pockets with it too....
For those of you who are unsure what a 3G sim looks like, here's a pic of the back of one:

the key difference is the "3Gc" notation.

LOL so I went to the store to get one, and they gave me one no questions asked, and even for free; but I found out I actually HAD a 3G sim already, lol. Oh well, at least I have a spare

yeah ... looks like the new one that I got...

What does the 3G card do for you? I get really good data speeds using a 2G SIM, and I am curious why I would need to update...
Would it happen to help with the problem I've been having transitioning between GSM and UTMS? Possibly? Please?

It certainly can't hurt to try. My Cingular rep told me that I wouldn't even be able to get a UMTS signal on Cingular's network without one. In Gravejoker's case this appears to be a case in point.

There's NEW Cingular 3G sims out now! With their firey 3G ball and all. Also apparently adds support for Video Calling, once enabled

No, I definately get UTMS on a 2G SIM. 700 - 900 kbps, to give you an idea of my data speeds. I also like the fact that I continue to receive emails when talking on the phone. I just wish the battery life was better when using UTMS; I often get 6 - 8 hours before it starts complaining about low battery. (Good thing I have a car charger and carry a sync cable in my notebook case!)

Maybe that's my case... Hmm...

Sleuth -
I have an old Cingular 8125 64K SIM card and consistently get 700+ Kbits per sec on U in the Washington DC Area. Never had a problem with U throttling down to G very frequently.
My Dopod 838Pro is configured for cell GPRS,3G. Aren't these speeds (from dslreports.com mobile speed test) typical of 3G?
Will I notice a big difference swapping in a "3G" SIM?
I'll try this out tomorrow and report the results.

Just look at your SIM card, if you have the 3Gc on the back of it, it's a 3G sim. The front says Cingular 64k SIM; which is why I thought I had an older one. Their newer SIMs actually have 3G on the front and all all blue . Less confusion that way I think.

How to stop network Roaming

I'm on T-mobile here in the UK and I can't seem to stop it roaming to Orange.
I don't mind roaming except when it choses Orange 2G when I have a 3G cell over the road from me on T-mobile. If I go into networks and after searching select T-mobile it will change to T-mobile but it will not stay on it.
How do you switch off network roaming?
I'm running ICS 4.04

same here

Switch off the setting in settings-> data usage-> advanced settings

Thank you for your reply but I didn't say anything about Data roaming. I need to stop it NETWORK roaming. I don't get charged for data when roaming on Orange as they are the same company in the UK.
As I said I need to stop it NETWORK roaming. Any ideas please?

Go into Settings | Wireless & Networks | More | Mobile Networks | make sure Data Roaming is unchecked.

settings, wireless, more, mobile networks, network operators, select network instead of auto?

Yes I have done that many times as said in my first post.
"If I go into networks and after searching select T-mobile it will change to T-mobile but it will not stay on it."
I don't understand why it keeps wanting to change when I have manually selected my network. Is this a ICS 4.04 bug or am I missing a roaming setting somewhere?
Ref. Data Roaming it has been turned off the whole time see screen shot

You mean national roaming ? I think that was in previous CM and only in CM, not AOSP.

So has anyone got any ideas how to stop this roaming?
I've just got home and it has roamed to Orange again, I've been home for 1 hour now and it is still on Orange even tho I have a 3G T-mobile cell over the road from me. If I manually select T-mobile it will go onto it but it doesn't want to stay on it.
I didn't have this trouble before I upgraded to ICS 4.0.4

I think you have to call T-Mobile and opt out as its NOT normal roaming(little R over signal bar) its a network specific thing

Virtual roaming control, from the market has fixed my similar issues in the Netherlands.. Maybe give it a try?

Radio Issues

Anyone else noticing an issue where you lose LTE in an overwhelmingly LTE area and it sticks on 3G? I have to use airplane mode to bump the radio back to 4G. This has been happening ever since I've had the phone. I'm curious if its just my area or if others are experiencing the same problem and if they've been able to fix it, what did you do? I have my MSL and I haven't taken the update so I am still able to edit my APN settings.

It doesnt happen to me. Whenever I dont have LTE is due to low coverage, especially when driving.

I have the same issue. The only thing that helps me is when i use it as hot spot is I mount it on my satellite receiver (pointing to signal direction). with a better signal it doesn't switch. I noticed with about 20% strength jump to 3G but my 3G is weaker and slower...

I have not experienced that problem.
SM-G935P

Mine really prefers LTE and rarely see it on 3G. If it does it's fairly quick to go back. I actually think it's too touchy it will hang on to a crap band 41 signal rather than a good 25 or 26 signal. A lot is of course going to depend on your area but I would try a radio reset.

Only time mine sticks is if im updating something or using data it wont switch back unless i move to another location outside of 3g or after the download

During this past week I lost all data connectivity. I was in a strong signal area where I have never seen a problem before. The only thing that looked wrong was there was no strength of signal indicator. My data signal has been set on automatic since I've had the phone. I changed it to LTE CMDA, the phone reset, and the problem disappeared.
Has anyone else had a similar problem?
SM-G935P

I had a problem over the weekend. I was in an area with no Sprint signal at all, and when I got back home realized my phone hadn't reconnected to Spring. I ended up having to reboot, then I got several messages and emails that had been pending.

I was going to suggest this action. Set your network type from automatic to lte/cdma. Then reboot. You may also want to run a profile and prl update. Last ditch you may want to run the HFA again. Usually just changing the network type will suffice.

MI Note 2 Users - Please test and confirm WIFI/4G/bands

Hey guys,
As this is a new release, I am keeping an eye out for tests of the stability and reliability of 4G LTE connections (the reception) and also the same for connecting over ac WIFI. Can someone please post some tests/videos/results?
Second. can someone also take a picture confirming ALL 4G LTE FDD bands supported. GSMArena and PDAdb.net both state this supports Bankd 29 700Mhz. is this correct?
Thanks

I have the CN edition rather than the global so I wouldn't expect to have Band 29 so I can't help you there.
In terms of general stability and signal quality with LTE connections.
They're very good.
I'm not sure what kind of test/video or result you'd want to see as it seems like there are always too many variables to get consistent test results, I can quite happily get 70mbps down on LTE using band 3.
As for WiFi - I'm hoping this is a ROM issue more than anything else, I'm unable to set my locale so I don't which nations wifi regulations I'm following (I'm using mi-globe.com as there isn't currently a global release rom).
I max out with a link speed of 433mbps on 5GHz (desktop achieves 1300mbps) and can't achieve more than a stated link of higher than 150mbps on 2.4GHz (desktop achieves 600mbps)
although the range is very good, and the eventual handoff to LTE is very quick too.
Is there something specific you're looking for I can help with?

Thanks for that. Yes, I think there is. Maybe see if you can set LTE only, or LTE/3G (etc)...do you get full reception at work, or in your home? Maybe just monitor it's strength without moving the phone from a typical "full strength location" and see if it changes. You can also run other apps that will utilise more of the CPU and RAM 9not necessarily internet-demanding apps) to see if they are a factor, in any way, on the radio strength.
I am mostly interested in the global version, what ROM it is (hoping different rather than just the CN with extra languages). As it's important to see what bands are supported, usually mentioned on the package... I also need to see the functionality of the dual sim and how the 2 interact when a data connection is active and a call comes in on the other SIM, etc. Screenshots confirming the SIM's connection sin the upper right status bar would also be benefical.
Thanks

Set to LTE only I get full signal at home and I haven't noticed anywhere in the city I don't have 4G, (at least while above ground).
It's not easy to make too much of a dent with that amount of RAM but CPU increased utilisation has no affect. I tend to keep my signal details as numerical anyway, that changed today when I flashed a statusbar mod changing my clock position so it's not in my screenshots.
You won't be seeing a difference in the ROM with global version, there isn't any reason to think they're releasing a separate ROM for the global version. The ROM that's out now is for all versions, I've taken it apart and the support in the current ROM is there for all the bands. I haven't worked out where they're limiting the bands but I've had a tinker. Changes to NVRAM values are lost on reboot and I haven't got any real reason to play other than curiosity.
If they release the phone internationally that would be when they release a global ROM; the differences there are localisations, removal of Chinese local apps (baidu, etc) and inclusion of google apps instead but nothing much more substantial than that. Was there something in particular you were hoping for?
No problems running data on one sim and receiving a call on the other, I tried this a few times downloading on LTE and calling myself via Skype (to my number not Skype -> i.e not local cell or data call). 10 out of 10 times there was no problem receiving the call and no noticeable impact on data speeds at the time.
Not sure how I show you with screenshots that one sim is active for data while another is active for voice, there's no indication when a sim is being used besides for data but I've taken some running an LTE network scanner. It'll only show networks on the band I'm currently active on (no idea why). Searching for available networks to join I can see LTE networks that use must band 7 (I assume, since that carrier has bands 7 & 20 - and well I shouldn't pick up band 20)
Hopefully you can gleam something useful from some of these screenshots, these were taking live as it was running. Since it's just network scanning here's no actual data flow hence why you see there's no data activity in the statusbar.

@StoneTrapper How do you find and rate the UI?
I've heard there's a few who don't like it and want to switch phones because of it.
I can see 4g/3g from your screens, so I wouldn't think using 4g and taking a call over3g frequency would be an issue given the CPU in this. THe lack of Band 28 (or many other bands for that matter) is a bit concerning

I'm used to MIUI, it's not my first xiaomi phone. I don't mind it, it's not ideal but there's nothing really unlikable about it.
People will always have their own preferences with roms, sooner or later xiaomi usually release the source code and the custom roms come flooding.
Yeah one of the networks I'm with only offer 3g, otherwise it supports dual LTE. If you want additional bands they offer a global edition that supports:
B1, B2, B3,B4, B5, B7, B8, B12, B13,B17, B18, B19, B20, B25,B26, B28, B29, B30
TD-LTE: B38, B39, B40, B41
I don't need the additional bands and the CN edition is already available to I went ahead and got that.

Nokia 6 on AT&T

I have just ordered from ebay a Nokia 6 32gb, I know this is the Nokia that is released in china. Now I have set up the access point to be the AT&T although when I turned on the phone it did have them set up automatically. I have checked on both of the settings the automatic one and one I have set up, and both show the speed to be HSDPA+ or sometimes it shows 3G, is that all I can get from the phone here on AT&T or is there a setting that I can change to get 4G maybe not LTE but at least 4G.

the phone is 4g supported and you can enable disable or change options here settings-data usage then select vertical..., head over to cellular networks and if your sim supports 4g then you can use 4g

I did do that on the settings, and still I have not seen it change to the 4G. I will try to play with the settings little more when I get home from work. But thank you for the help.

LTE bands supported by Nokia 6 Chinese variant (TA-1000) are 700, 800, 850, 900, 1800, 2100, 2300,2600. So make sure if LTE band supported by your SIM falls on it.
Sent from my TA-1000 using XDA-Developers Legacy app

So this is what google says:
"AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands but it all depends on area if they own a license. LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently."
So it should be on, yet 4G dose not show up.
But I started to have one other problem with the phone, I started to eat battery like crazy about 15% an hour, and I been using the phone for 1 day, and it started to get pretty warm. Anybody else having that problem? Should I start a new thread with Nokia 6 problems and fixes?
