Hi,
I have an Att tilt (stock) and at work I loose phone signal.
I had a similar issue with my sprint phone and phone service. When the setting for “roaming or sprint network” was set to “automatic” I would loose signal all the time. Instead for the phone locking into the roaming stronger signal (Alltel) would try to lock into the sprint weak signal all day (going in and out resulting in lost calls). When I had that setting to “roaming only” it would lock into alltell (the stronger signal) with 5 bars.
On the tilt when I go to phone/settings/network the only option is “find network” and that option looks for att and not anything else. Is there a way to force my att tilt to roam only and therefore lock to the alltel network (very strong signal)? Or expose all the available networks and choose which one I want to lock in?
Thanks for all the help, this is a great forum
cannot locate different networks
im having the same problem. phone has bad at&t signal. I cannot locate a diferent network.
Forcing roaming with tilt
I guess the question is…Is there a way to force roaming only in a stock att tilt?
Thanks,

Anyone?
Thanks for the help
Bump again....I want to know the same thing. I have free roaming, but I can't get it to roam.

Does the phrase “PRL file” provide any help?
Is this an editable file that can solve the issue?
Thanks

I'd like manual n etwork selection as well, but you may be roaming and not know it. AT&T sets up all their phones so it looks like you are on your native network, even when you're not. I had bypassed this and enabled manual network search on all my Motorola phones, I'd like to do the same here with my Tilt.

i suggest setting the band in settings/phone to wcdma. Try it.

I don't have that setting. AT&T removed it. In 3G mode the field test doesn't do much. In GSM mode it seems to work well.

The stock HTC ROM allows this, but it didn't seem to do anything. I know because the ATT HSDPA network is available at my house (barely), and when I lose it it switches to a full signal Edge.
But! If I switch to GSM it seems to lock to the much better Edge signal at my house instead of the HSDPA. That works for me, but will it limit my signal elsewhere?
I had the same problem....the network found was AT&T all the time and no signal, so I place the Sim in a friends Nokia with manual network selection and choose T-MOBILE, place it back in my tilt...problem solved !!
Note: I'm an international user, only use roaming when in USA. But this may help you guys !
Forgive me for cross-posting, BUT: it seems this is a REAL big issue for many users...
We're looking for a way (=tool/app) to disable GPRS data only in order to avoid roaming data connection costs (from 0,50 up to 2,00 euros/MB) while keeping the chance to connect to GSM networks (if needed) for roaming calls.
If anyone will pop out with a working solution for that issue, there's already a number of us ready to donate in order to contribute/reward the author(s)!

You're right (I was editing my original message), but it would be desirable to keep the chance to connect to GSM networks (if needed) for roaming calls otherwise we loose connection and voice calls functionality in areas serviced by TIM with which H3G has a roaming agreement...
Should not be a big issue to make something like that, however...
Why wouldn't HSDPA be available while roaming? I have HSDPA here while roaming as well... :/

It very much depends on operators' agreements!
In Italy H3G has a "national" roaming agreement with TIM: whenever an H3G customer is out of H3G signal coverge, the phone is allowed to switch to the TIM network, BUT the only data connection available is GPRS, not UMTS/HSDPA!!!

Guys,
the "incredible speed" is related to how fast the bill grows, not to the GPRS data connection speed...!

I recently installed the eOS 4.888.FiRe ROM on my Tilt and it has been working nicely. I noticed some additional settings that weren't available to me when I was using the stock HTC ROM. What is "HSDPA" and "AGPS"? And will it cost me to leave these turned on? I notice when I turn on HSDPA, I see a an "H" icon at the top rather than the usual "3G" icon.

anyways simple answer:
hsdpa is a form of data connection which is faster than 3g.
agps stands for assisted gps. it is same as normal gps except that agps uses a server to cut down on the time to requires to get ur location using gps.
both won't cost u anything extra but ur carrier does need to support them for u to be able to use.
Thank you. I just wanted to know if they both won't cost me anything extra. You never know these days with Cellphone companies. I turned on both HSDPA and AGPS. So far my calls have been going through just fine and my navigation software continues to function normally.
How do I know if my carrier (AT&T) supports HSDPA and AGPS? I hate having to call customer service to ask so I'd rather ask here.

I used KaiserTweak to set my phone to HSDPA. I am an AT&T user. It's worked fine. No additional charges. I don't use AGPS so I can't respond to that part of your question.

Thanks for your response. I just use it for voice calls anyway. Do you see any improvements? Or is it specifically if you subscribe to a data plan? And do you also see an "H" icon at the top rather than a "3G" icon?

HSDPA has to do with you data connection, so unless you have a data plan you really won’t see the benefit.

google
v. (Computers) search for data on the Web using the search mechanism Google; search on the Internet for particulars relating to new or likely to be girlfriend or boyfriend
HSDPA doesn't cost anything to activate, but if you are on a restrictive tariff it is a lot easier to run up over usage charges.
In the UK you need to usually be paying at least £30 a month to have the unlimited mobile broadband and e-mail. I would personally check your contract before you let the HSDPA run loose.
Rob
As mentioned multiple times, neither HSDPA or AGPS will cost you anything. You will know if you are in an area that has HSDPA because of the H icon. If it goes back to 3G then ATT does not have HSDPA in that area. If it goes to E then you are back on Edge. As also was mentioned, neither of these have any impact on your phone calls. HDSPA = Data and AGPS = using the cell towers or the internet to help you lock on your GPS location quicker.
And yes, if you had used google to search for this you would have probably got a better explanation in a less amount of time.
Hello I seem to have a problem and I am hoping someone can help. My phone is rooted running Modaco r20 Desire Rom. Radio is ERE27. I have a strong 3G signal in my town with T-mobile. My problem is that for some reason whenever I use data (internet,online gaming, searching using apps etc) the icon will stay on 3G then switch over to H. Sometimes it will stay on 3G and it will not allow any data. I know about the EDGE to 3G issues. I don't seen to have that issue. Can anyone help and or know why this happens?
Usually, when browsing the internet or anything is being downloaded at all - the 3G icon will switch to H. Really only in custom ROMs though, I don't really believe this happens in the stock ROM.. it's not a bad thing or a problem, at least not for me.
Data doesn't completely shut off for me though.
The "H" means you are achieving an HSDPA connnection of sorts. Stock does not have this icon in it, since HSDPA is a form of 3G and they didn't want people getting confused by it switching from 3G icon to H icon.
HSDPA is faster than basic UMTS, aka "3G"... so it is not a bad thing at all.
No idea why you loose your data connection all together when it switches, since it isn't doing anything other than recognizing you have a faster data connection than basic 3G, nothing is actually changing to cause you to lose your connection since it is still the same connection.

no it is not...
mine does the same thing... i have to twiddle my thumbs and wait when it switches between UMTS and HSDPA... they are different frequencies just like EDGE is on a different frequency...
I don't think UMTS and HSPA are on different frequencies, the same two frequencies are used (alternating for downlink/uplink) for both, those are 1700mhz and 2100mhz.
For some reason I don't have this problem on Long Island, but when I'm in the city this happens the whole time. Might be something to do with the way the network is configured. Basically whenever data is in use, it just says 3G, but as soon as I browse to a site or actually use data, it switches to H within a second or so. I think a stock ROM would technically be doing the same thing, but it just won't show the actual switch, as it doesn't differentiate between HSPA and UMTS in the top 'taskbar.' Although it would probably show this in the phone status screen under settings.

The "3G" to "H" (and back) is a "red herring". If it's "stuck" on 3G when you're trying to do data, it means your handset is having issues communicating in the AWS bands for 3G (2100/1700) and the handset hasn't dropped back to GSM/GPRS/EDGE (1900) yet or is attempting to switch frequencies and the associated towers aren't cooperating with the hand-off or the hand-off is failing.
Cheers,

I'm in times square. My phone has never switch to UMTS. Either HSPA or EDGE.
also while it's idle it will only use 3G
it will switch to H to transfer data, then revert to 3G

Not that I've found. I have this problem BAD here in Phoenix. I never even bothered with WiFi until I got a Nexus, now I can't live without it. I found that sometimes kicking the phone in and out of Airplane Mode sometimes alleviates it being "stuck".

Which Modaco ROM? If it is Desire, you have to flash the newest radio, and do it after flashing the ROM itself, otherwise you will have major Radio issues... at least that is my, and a fair number of other's, experience.

Yeah its Desire rom. I have radio ERE27 right now
Try upgrading to the newest one, 32.26.00.24U_4.04.00.03_2:
http://android.modaco.com/content/g...-online-kitchen-optional-root-insecure-himem/
Make sure you have at least 50% battery before flashing, just download and flash via recovery just like a ROM, do not panic, ever, during the process and do a battery pull, just wait for it to flash, then ask you to reboot, reboot, it will then do the actual radio flashing (you will see a box with arrow screen for a couple minutes) it will reboot on its own into recovery, say "writting" cache with a progress bar for a few seconds. The bar will go away, but the "writting cache" text will not, don't worry it is done, just reboot and then double check it flashed by going to about phone, software, and checking baseband version.
Just remember, can't stress this enough, do not pull your battery at all during this process. And make sure you have at least 50% battery before starting. Flashing a radio is the only way you can brick an N1 right now, and only if you pull the battery during the process, or have a bad download. Speaking of which, I do recommend checking the MD5 sum to make sure it is a good clean download.

Same thing happens with me. I'm in Phoenix myself with T-Mobile and running Cyan 5.0.5.3 with EPE54B and baseband v 32.26.00.24U_4.04.00.03_2.
I'll have full bars for 3G and when I goto check the market or anything internet related, the 3G will switch to H and work or stay at 3G and pause with connection error, retry or cancel.
I started having this issue after updating my factory stock radio. Anybody know which one is the stock/default radio IMG is? I'm thinking of downgrading and seeing what happens.

Uh..unless you changed you radio settings to "WCDMA only" you should be able to talk and surf.
It should work. I do it all the time, but it is network dependent.
In case it works on your TP2 i suggest you check your settings.
Hey big guy are you using a t-mobile nexus one on AT&T? Or AT&T N1 on T-mobile? That used to send all my calls to voicemail while I was on the intarwebs

Incorrect. "WCDMA only" is still UMTS/HSPA (3G/3.5G in consumer speak), therefore you still get voice/data at once. I can only conclude that you're under the assumption that UMTS/GSM work the same way EVDO/CDMA does. On an EVDO network, all data goes through the EVDO network, while voice stays on 1xCDMA, because EVDO is an addon to 1xCDMA.
UMTS and GSM are two completely incompatible technologies that only share GSM backend features and a SIM card. The circuits in the phone are separate, the antennas on the towers are separate. You're either completely on UMTS for voice and data (inc. both at the same time) or you're completely on GSM (for voice or data but not both at once. In fact, if you're locked on to a strong UMTS signal, the parts of your phone that handle GSM shut down for power conservation and only wake up when your signal drops to check to see if you'll get a superior signal over GSM. It will do this periodically, but won't stay active for long unless your UMTS is so bad that you won't be able to hold a call. THEN your phone powers up and maintains the GSM radio, while putting the UMTS radio on standby, only powering it up momentarily to look for a better signal.
The only time you have GSM and WCDMA/UMTS powered on at the same time is during hand-offs from one network to the other. That's why staying in areas where you bounce between the two kills your battery so quickly, the radio is drawing roughly twice as much juice as it normally does, plus it's computing which one will do the better job for the moment. Even then, at that time, the phone and its OS will be using only one of the networks at a time, and if it's UMTS, you'll be able to hold a call and surf the web.

Have you ever changed your build.prop file at all in the past? If so that's the problem. Change to hsxpa=2 to fix it.
If not then I have no clue.

When you have bad reception, that's what happens. Normal and expected. During the call it won't re-negotiate 3G, only when the call ends.

Yeah, that is normal and it really sucks when you're on a long call. Once you lose 3G signal it's gone for good. I don't know if it's a network problem, or the phone, but it should be fixed.
