Can’t change network and roam with Att tilt

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,

Bump
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 !

Inabuilty for Simultaneous Voice and Data

Why is the Nexus One unable to do Simultaneous Voice and Data.
I have searched hi and low.
And yes i am in a 3G area and all that jazz.

I am in 3G.
I have no problems when putting my sim in my tp2. And talking while surfing.
And i am not the only one. No one has givein a reason as to why.

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.

TMO on TMO.
Attached are my settings.
I have this on every rom or radio i try.

Hey, sort of same thing just happened to me
in my case using GSM Auto (prl) or WCDMA prefered I can connect to HSDPA but GSM is in emergency calls only, weird.
but I can do both on GSM only (GPRS/EDGE)

Re-flashed to official release of 2.1 same thing.

i use voice and data on my nexus at the sme time every day. it just works. as long as you have a 3G symbol next to your reception bars, then it works.
i dont know what you could have done to break this. can you demonstrate to us what you are doing that is not "working"?

I am connected to 3G network. Call comes in. I can not browse on the internet. While i am on the call i go check settings and i have droped to GPRS. As soon as i hang up i go back to 3G (HSDPA)

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.

It is.
I have no problem on my TP2.

I use it often too but today I was unable to it. Hopefully its because my area is being updated to hsdpa+

i think i have the same problem. 3G drops during voice call, doesn't connect during the call. reconnects after the call ends.
stock nexus one tmobile FRG83D

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.

[Q] Unlocked but no mobile data

So I've recently purchased an unlocked Sprint HTC One. I am able to use my current tmobile sim and am able to send/receive calls and texts. The only problem however, is that when I try to turn on the mobile data, it won't connect and just says "disconnected." Can anyone shed some light as how I can approach and resolve this problem?

Does the phone's GSM radio use the same frequencies for data that T-Mobile uses?

I know that the Sprint HTC ONE doesn't have the 1700 Mhz band, only the 1900Mhz. I've read that even if I'm not in an area that is refarmed to the 1900Mhz band, I'll still be getting edge. I live in the Los Angeles area so I'm more than likely to be in an refarmed area.

Connect to wifi and update PRL and profile.
If nothing, try forcing hands-free activation. In the dialer: ##72786#

You probably need to setup T-Mobile's APN to get the data to work. Not sure how to do that on the One though.
BTW, expect GPRS/EDGE data to be quite slow, even if you do get it working.

I haven't had to do anything special with APNs for Tmo data. I get Edge in the non-1900mhz areas and HSPA+ in the 1900mhz areas.
In the Mobile Settings page... I have all roaming guard options unchecked. GSM data checked. Set to GSM/UMTS only. Search for networks.. click on Tmo... and away I go..

I've tried unchecking all roaming gaurd options and I still get the "disconnected" message. Do you mind sharing what your APN settings are?

I've never touched anything related to APN. just select TMO after the network scan and use. Id assume the APN stuff is auto-populated by htc/sprint settings built in.

I tried resetting the APN to default and reconnecting to the TMO network, however, I still can't get any mobile data. I'm hesitant to seek TMO for help as often times, they'll just reply saying that it's a Sprint model, so not everything will work.

So I got the mobile data to work, however, only when I'm out and in certain areas. At home, it still says "disconnected" however, if I'm out in some areas, I'm able to connect to the 1900MHz band. Is there a reason for this happening? Mind that I was only probably a mile away from my house.

Was there a solution to this ? This is my problem also in los Angeles

[Q] Force phone to stick to low signal LTE rather than switching to 3g?

Hey guys
So I looked around the forum for an answer to this question and i found similar topics but not exactly what I was looking for. I have the HTC one with sprint and the only issue I have with it is how it handles its preferred networks. If have 2 bars of LTE but 4-5 bars of 3g its going to stay on 3g and not switch to LTE. Is there anyway to change how it gives each signal preference. Currently it will wait till there is no 3g signal before it switches to 2g but LTE is not giving the same preference. I know it's just this phone because I had the iphone 5 before this and when I was on campus at my university it would stick to the 1 bar of LTE i had rather than switching to 3g. If I force the phone in LTE only mode then it will pick the LTE signal but then I can't call and text obviously so it's not very useful.
There are two things that the iphone 5 did which I miss but otherwise love this phone. One is getting LTE in places that has low coverage and the other is roaming on verizon network on 3g. The iphone would always roam on 3g but the htc one only roams on 2g.
Is there a way to change those things with this phone? Thanks in advance!

Have you tried changing the preferred in the *#*#4636*#*# > Phone Information?

Hi thanks for the response. Yes I have messed around with that. That's how I got the LTE only option. It isn't a matter of not finding LTE signal. It's just the way the phone handles what is perferred. The phone first sees if there is a strong LTE signal and it catches that but the moment it goes to about 3 bars or less it will switch to 3g. I want it to continue sticking with LTE until the signal is gone completely like it does with 3g -> 2g.

If its that way then I belive a builder will be able to forge a flashable zip for that purpose.

I see. And who do I ask for that? Or how can I build one? Sorry I am a bit of a rookie in this. I don't want to mess around with it too much but can learn. I thought there might already be some sort of hack or a modded PRL.

any new insight on this by anyone? thanks
I have lte at my work if I do lte only but it will switch to 3g when i turn everything else one because 3g signal is stronger than lte. id rather use lte however but still have my texting and calling capabilities.

I know it's not an optimal solution, but have you considered using Google Voice integration in the meantime? With LTE only mode, so long as you're signed into an app of choice (Google Voice/Hangouts should be able to handle your calls and texts if you tweak at it a bit), you should have the desired service until you can get some dev help.

Signal but no bars

I am using about unlocked and rooted US Cellular phone on T-mobile. It's working and I get clear calls, but I do not get any visual "bars". It's not a major concern, but the OCD kicks in now and then... lol.
Any idea how to fix this?

US Cellular is CDMA and T-mobile is GSM. I am surprised it even works but my guess it's that your phone does not know how to read the signal and or does not have a symbol to use.

Attached is an image showing what I am describing. Also an image showing that I have it at for Global. I also tried Lte/Gsm
