Problem Text Messaging outside of my home!

Hello guys, i'm about to pull my hair out from frustration! I have an unlocked Tilt, on T-Mobile running on the HTC windows 6.1 Rom and for some reason i cannot send or receive text messages if i leave a good distance from my house!
Once i'm near my house by a block or so i'll receive and send text messages no problem, but there are patches around my town where i can't send or receive it. I tried switching my Sim card to an older phone and texting where i couldn't text on my Tilt, and the texts went through no problem, i just need to know if it's my phone or the carrier's fault. I plan on testing my Tilt and Wing in the same area's to see if that can shed some light, but i need help!

What's the reception like? You might try flashing a new radio, might give you better reception in some patches. What wm6.1 rom/radio are you using?

Currently my Rom Version is 3.03.405.0 WWE
Radio Version 1.64.06.04
I've tried countless rom's at first i thought it was because of windows 6.1 so i tried the HTC Windows 6.0 rom which didn't work either.
If you think i could use a better rom would you please let me know, i'm willing to do anything to fix this problem!
Thanks

i think it has nothing to do with a better rom...its just if the radio is fitting for the location u are at

I have several wm6.1 radios in the link in my signature. try them and see what you get. i am using the niki 1.58.16.27 radio. i like it the best, but it really depends on your location

thank you for your reply's i will try different radio's and see which one works best for me, thanks once again.

no problem man, that's what we're all here for.

One quick question about Radio's, are they just for signal strength? because i can make and receive calls just fine in areas, but no matter how strong my signal is i still can't send/receive text messages.

well i don't know for sure that changing the radio will make any difference but it might help. you're having that trouble just with the sms huh? and always only in those areas?

Yeah it seems touch and go, in some places it refuses to work, but in others, such as my home it works flawlessly. It even worked on the freeway on the way to Canada, and even in Canada on Roger's network. I tried calling T-Mobile and they thought it was weird how it works in some areas but not others.

that does seem very odd. hopefully the radio change helps, otherwise you'll have to find someone wiser than me to help you, or just chalk it up to a network glitch. good luck

Please make a follow-up post to let us know what your findings are. It's an interesting problem you're having, and your data could be very useful for this and other issues!

So far tried a number of different radios and still haven't fixed the problem, but i've singled out the problem as the Phone, as i tried texting in places where i couldn't with my Tilt, on 2 different phones, one being the Tmobile Wing and they went through with no problems.
I'm gonna try Dutty's 6.1 rom and see if that changes anything, i'm pretty much trying anything that works now.

So just to be clear, when you use an unlocked Tilt on T-Mobile's network, you have difficulty receiving text messages. But when you put your SIM into a T-Mobile phone (Wing), text messages come through fine? If I understood your posts correctly, and my summarization is accurate, then it sound to me as if the Tilt is having problems accessing data services when its roaming off T-Mobile's network.
I would make a note of 3-5 specific areas where you have problems with SMS (ie 300 Block of N Maple Ave), and then call T-Mobile and ask them where their closest cell tower(s) is/are to those areas.
If my memory serves correct, T-Mobile uses GSM 1800/1900 in the US, but AT&T is still mostly 850/1900, and the Tilt may have issues receiving SMS messages while on a GSM 850 tower. You mentioned that the phone worked in Canada on the Rogers network, maybe they are on 1800/1900. Can someone from Canada confirm this last part??
These are just some thoughts of mine as I mindlessly watch TV, so who knows, I could be entirely wrong...

Hmmm interesting, now if i informed T-Mobile of this problem is there any way to remedy it without having to go back on a Tmobile phone?

is your tilt set to text through gprs or gsm? that might make the difference..

If it is an issue with GSM 850, then you may be stuck with running cooked ROMs based off of AT&T originals since their network still supports this frequency. To my knowledge there are no WM 6.1 ROMs with an AT&T base currently available.
It could also be a hardware issue... The section of flash memory on your device that stores the radio could have bad sectors (GSLEON3 would be someone who may be able to help you check this).
How did you come to get the Tilt? If you know someone with AT&T service, you can have them put their SIM in and then call AT&T Warranty and get the phone replaced under the 1 year warranty.
EDIT-
Second thought... Have you tried to force the phone into 1800/1900 GSM through the Band Settings tab under Settings --> Personal --> Phone --> Band ?

Currently it's set as GSM, do you think i should change it to GPRS?

Hmm i didn't even think to check their, i'm going to try it right now and report back.
EDIT- So should i be setting it at GSM(900+1800)+UMTS(2100) or GSM(1900+850)+UTMS(1900+850)?

WOW, Finally, thanks everyone for help but forcing the phone into the GSM 1800 band worked now i can finally fully enjoy my Tilt, Thanks once again!

Connection Problems

Before i decided to flash a new rom i had been having issues with my phone getting, and staying connected. At first to just data connections, ie 3G. So i decided to try a cooked rom for the first time.
But since then i've had even more troubles getting my phone connected and keeping it connected. Ive been through Hyperdragon III Opal, Dutys latest rom, and now im on the latest AT&T rom, and still im having troubles. Ive hand entered in the Media net connection info so many times ive got it memorized, ive even tried cabs, turning proxy on or off, and just plaing letting it sit for a while. It seems as though every time i try something new it might for a second but next thing i know i lose connection and can't get it again without restarting my phone.
If it helps im currently using HardSPL 3.56, and my phone is running the AT&T ROM version 3.57.502.2 WWE and radio 1.65.21.18
This is a very urgent issue for me as in my job i use my phones internet almost daily.

Ok for a while there with the stock AT&T rom it was working just fine. I went to start adding in a few cabs and it was like my phone once again decided to hate me.
Im not trying shogunmarks DeathV4.1 and have NotATreoFans AT&T v3.2.5 Loaded downloading in case the other doesn't work. I don't even really care about having a really awesome cooked rom, working is about all i am after right now.
UPDATE: Tried both of those ROMs to no effect. ive now broke down and rolled back to the original ROM and SPL that came on my phone when i bought it from the store. I pray this at least gets it working long enough for the Touch Pro to come out and me to get enough money to buy one out of contract. Still if anyone has any ideas im all ears.

Ok i hate adding a new reply or bumping this but now things are getting desperate. I have been through checked and changed every setting, tried everything. now its not just data, the phone itself wont work as a phone. Calls wont go out or come in. If someone trys calling my phone it never goes through, it wont even go to voice mail. This makes no sense at all.

All that comes to mind at this point is a defective phone. If you bought the phone new, then it has a 1 year warranty on it, and AT&T will replace it for you. If it's been less than 30 days, then just box it up and go to an AT&T store for a full exchange.

Set the phone band to GSM manually and see if you can make phone calls. If that works then search for 3G problems. There are a lot of bad devices which suffer 3G not working.

Connection Settings
How did you set-up your data connection? Manually or automatic config?

Thanks everyone
UPDATE: I called support after rolling my phone back to its original shipped ROM and SPL, and man did the guy at the call center almost crap when he heard how early of a ROM i was using. He said i have to install the newest update first then if its still borken (considering ive had the newest one on here before, i already know the answer to that) that they will send me a new one since im still in my warranty period Yea for customer support

Phone shows full service but I don't receive calls

Sometimes people call me and get a message saying my phone is off or out of service. But when I look at it, it often shows 4 bars of service..
When I call someone, the problem disappears temporarily, and I start receiving calls again (and I receive all the SMS's I was supposed to get at once), only to appear again later for no reason (a soft reset also solves it). It's not related to location, it also happens when I spend the day at home (where I get a strong signal).
I don't think it's a operator problem either, since my operator is known for it's good services, and other people who use "normal" phones never had such a problem.
I tried 3 different ROMs (dutty's hybrid, Hyperdragon and AthineOS) and 3 different radios (dutty's radio (1.65 something), hyperdragon's (1.70 something), and eMo radio). Right now I'm using AthineOS with hyperdragon III's radio, and almost no programs installed..
This problem happens both in 3G and EDGE mode.
Anything I can do about it?

Send it in for repair?
Seems you tried all you could...

Don't think I can send it for repair, since it's an AT&T Tilt and I'm not even in the US..
Guess I'm outta luck then
Anyone else have any ideas?

have you tried the sim in another handset, sounds like a network problem to me.

3G Network
Are you using 3G Network?
Sometime I use 3G band and even It show good signal I loose phone calls.
I changed to GSM and no phone calls loose.
This happens in São Paulo/Brazil but...
EDIT: Sorry. Now I saw that you reported this problem also using GSM band.
Thanks.

I am not sure if you're using your US SIM card in a foreign country?
Maybe you just forgot to enable INTERNATIONAL ROAMING before you left ... ?

I'm having the same problem
I seem to have started with the same problem about a week ago. A couple people complained that they called me but it rang twice and went to voicemail - My phone never rang. However, after I made a call (or apparently did something to "wakeup" the phone), I would get the voicemail notification (2 hours later).
I tried reseating the SIM card, but then it went to "SIM Card Missing". I did a hard reset, but that didn't help. I took it back to AT&T and they replaced the SIM Card. That seemed to work again, and certainly would have been a convenient fix (bad SIM card - too easy). So I've just spent all weekend reloading all the apps, but now it's happening again!!
The symptoms are; After I reboot the device, I can receive one or two calls, then it doesn't ring anymore (the caller hears 2 rings then it goes to voicemail). If I cycle the Phone radio button in the Comm Manager, or cycle power, it comes back to life for 1 call, then craps out again.
I'm just using the standard AT&T ROM (without the Bloatware after this past reset) and the standard/default radio version 1.27.12.11
The only thing that I have noticed that seems different lately is that the "Comm Manager" task is always running when I look at the running programs (which I don't think it used to) I had also recently installed Garmin XT.
The device is of course 1 yr + 2 weeks (so I assume just out of warranty)
Any help would be greatly appreciated!!!

Hmmm,
what I would try, is, to just make a hard reset, load only my contacts to the phone and run it for a while to monitor its "Incalling" behavior. If everything seems to be fine, I would go ahead and start installing an application, then monitor my device again for a while, if everything is fine I will go ahead install the next application ... and so on. That is just to make sure that no 3rd party application causes this problems.
BTW:
I don't think that GARMIN causes this problem. I used to run Garmin on my HTC too (v5.0) until I came accross SYGIC McGuider (which works much better and card scrolling is much smoother than Garmin).
Well,
to come back to the point: if you get the same problems without loading any 3rd party application on your device, then I would recommend trying another ROM (best advice: go with the HTC stock ROM). If it also happens with the other ROM then it might be hardware related and difficult to fix.

Thanks - I knew that's what I should do, I just didn't want to do it after having spent all weekend reloading and configuring it. I thought I had read somewhere about Garmin having to have the phone radio on to work, so I was hoping there was a setting somewhere that I was missing that was powering the radio down. But..... I suppose it's time to go back to common sense and just do the reset
So far it seems to be working now. I'll give it a few days with just the basics and then start reloading one at a time.
Thanks for the quick response!

Spoke too soon
looks like I spoke too soon, it's doing it again - seems like it was fine for about 3 hours, but now .....
guess it's time to try my luck with AT&T - time to see how good their customer service is

Well, I'm experiencig totally same stuff here. I don't know whats really going on. I've NEVER before had such or even simialr problem.
Ive installed stock HTC ROM. And its going again.
One question. Are you using Opera Mini maybe?

no, I was just using the default browser.
I've got nothing installed on it at this point so I'm guessing it's hardware related.
Over the last couple months I had been experiencing some strange battery drainage (not related to the GPS issues). I don't know if that was a symptom or not. It just seems like the radio is going to sleep somehow - it wakes up for a little while if I sync my email, cycle the radio via comm manager, or cycle the power.
Anyone know if there is a setting somewhere that controls that? (sure would be nice if it were that simple)
The AT&T store was basically useless, all they did was give me the phone number for the warranty department (but since I'm 2 weeks past warranty, he doesn't think they'll help me), and of course offer to upgrade me to the Fuze for $375 - no thanks!

I've had the same issue (I think). I too think that it seems to happen when I have a 3G data connection active and moving back to GPRS (non 3G) seems to make it better....
I'm on a standard UK ROM and using BTMobile as a provider.
I was driving down the motorway the other day and overtook a friend. He rang me and went straight to voicemail. I then got a text to say that I had a voicemail and rang him back.
I was running TomTom Traffic at the time so would have had a data session enabled....
I think its something to do with the data session sometimes not letting a call through but can't put my finger on anything and certainly can't find an option to change any settings...
Also, even at home, I'm constantly picking up my phone to see that it "has no signal" and the exclamation mark is displayed - so calls aren't coming through - but it then connects and shows a three-bar strength signal. Don't understand why it keeps dropping out, but I get a 3G connection at the front of my house and an ordinary G connection at the back and I think that it sometimes to stay connected to the 3G connection for data even when the phone signal is very poor and it would be better dropping that and connecting at "old" GPRS speed...
Same on the train on the west coast main line out of London. I think having the 3G turned on causes the phone signal to drop out completely more than when 3G is turned off, as the phone tries to hang on to the signal of a 3G cell and doesn't successfully switch over to the next "non 3G" cell whilst in a call.

have you tried a new radio such as NIKI's?

well, AT&T warranty was even less than useless. Home phone, Internet, and Wireless all through AT&T and the best they can do is "see if they could get me a deal on a new phone" or refer me to HTC technical support. Nice customer service AT&T!!!
HTC technical support was actually trying to be helpful, once she found out I already did a hard reset, she referred me to their warranty group. They looked up the S/N and it's still under their warranty (I guess theirs is 15 months after manufacture date). Now the only problem is I have to send it in to them to see if it's covered under warranty, and of course be willing to go without my phone for 2 weeks (and pay them a yet to be determined amount if they decide it's not under warranty).
I'd like to try a different radio, but looks like there's too much for me to read up on - I need to get the device fixed, I've already lost too much time with it being messed up and me screwing with it.

Update
so this morning I was ready to throw in the towel and send the device back to HTC. At least they were willing to help me out, unlike AT&T.
I get to work, and of course the phone seems to be working (which isn't unusual, it works for a little while then craps out). Come lunch time, it's still working (now this is unusual, it must be a fluke, I'll give a couple more hours before I package it up). 4:00 and it's still working! Now I'm starting to wonder if it's got to do with the cell towers near my house (and the AT&T store since it did it for them too).
I email my buddy who lives about 1/2 mile away and also has a Tilt just to see if he's had any similar problems. He calls me back laughing. There's 5 People in his office with the exact same problem (and not all Tilts either).
So to make a short story long....... it appears to be a problem with AT&T, NOT the device (but Thank You very much AT&T for the incredible customer care you demonstrated and for trying to screw me into buying new devices for outrageous prices)
So at this point, I'm not sure if it's that AT&T has fixed the issue across the board, or if it was the "Resync the routing" that the online chat person tried last night that finally propagated across the network (I assume so that AT&T can find my phone in order to route the calls to me).
I guess we'll see if it does the same thing when I get back closer to home tonight, but I'm relieved that it appears to be fixed.
Thanks everyone for the suggestions! Now I have a little more time to read about how I can screw up my phone on my own schedule - all the practice of resetting it and reinstalling everything, and seeing how much faster it is has inspired me

Hi bbaydiver
Did Att fix your problem? I had same issue with my tilt 8925. I tried all the orginal Att rom "same problem". After couple minute, I can't receive and make call. thanks

I didn't tried asking AT&T for a new sim card. but I will call them to change the sim card. Does anybody know how to disable the 3G function?

Just a "me too..."
Hello everyone. I just wanted to report that I'm having the same issues...they started about a week or so ago.
I've had my AT&T Tilt for about 8 months now (it's a warranty replacement for my first tilt, bought in July...so of course, I'm out of warranty). I recently had problems receiving calls, and then I started being unable to make calls, even though my phone shows a decent signal...anywhere from 4 bars to 2 bars. When dialing, it'll say "Dialing..." for a few seconds...and then it clicks off. A soft reset will fix things temporarily, but that's it.
I'm running the stock AT&T ROM (I'll check the version number if someone thinks it'll help), and I've tried doing a hard reset AND replacing the SIM card. Same effect.
Someone please let me know if they resolved this problem. AT&T offered me an HTC Fuze...but I'm extremely wary of other phones by this manufacturer. I'm very, VERY tired of phones crapping out on me after having just spend a couple of hundred bucks on them. At this point, I'm just looking for something reliable. If someone else here has had problems with the Fuze, please let me know...not to start any fights around here, but I'm actually thinking about going with the iPhone.
Thanks.

SX66 Help

I just got an SX66 and my current carrier is AT&T. I put my SIM card in the SX66 and cant get it to make any calls what so ever. Any Ideas please?
Windows Mobile v 4.21.1088 (Build 15005.1.2.1)
ROM 1.33.10 WWE
Radio: 1.02.10
Thanks!

welcome to the forum!
could you describe your problem a little further? is the sim card rejected, then you might want to sim unlock your device, a tool for that can be found here: http://wiki.xda-developers.com/index.php?pagename=BA_Unlock_Sim

The phone does not reject the SIM. It just wont connect to the AT&T network. Ive tried the unlocker and it dosnt work since the it recognizes the SIM. Ive seen everyone unlocking it for other services, but no one for AT&T so far.

Umm, last I looked, the unlocker programs don't care about the carrier you are on or trying to use, unless you are trying to lock the phone to a specific carrier.
The SX66 was originally sold by AT&T, so you shouldn't need to unlock it, unless someone locked it to another carrier.
Basic steps (not trying to insult anyone here):
Are you sure it's an SX66?
Does the SIM work any other phones? Which ones?
When you put your SIM in the phone and boot it, what does the display show? Any error messages?
Does the aerial icon at the top of the screen show any bars?
Checked the comm manager to make sure the phone isn't starting in airplane mode?
Also, unless I'm remembering incorrectly, that device is using the original OS, you might want to look into upgrading that ROM and radio stack.

I just upgraded the ROM to windows Mobile 6.5, and yes it is a Cingular branded SX66. The SIM card works in my AT&T LG Neon. It searches for the carrier, and just displays the exclamation point next to the antenna. The SIM is a blue and white AT&T card, with 3g on it.
And thanks for all the help.

Hmmm...
Potential issues:
Band coverage: Of the three bands the LG supports, the angel covers them, so non-issue
SIM type: This might be a problem. Mind you, I've not been an AT&T customer in years but I have heard of this kind of thing happening, where the SIM is a 3G-only SIM (not the case here as the LG isn't a 3G phone).
Making some guesses here...
The phone doesn't complain about not being able to read the SIM, but it can't associate with a tower. It might be the SIM just being too new and the angel hardware doesn't quite know how to deal with it. You wouldn't happen to have another SIM to test it with, or know someone with an older SIM or different carrier that you might be able to drop in the SX and see? It is possible that the hardware is just dead, but without other SIMs to test with, it's hard to say.
I know that I had a friend that had an AT&T SIM that went in a 3G phone. He borrowed my old T-Mo 2G Nokia (unlocked, of course) when his AT&T phone was pinched, and the Nokia couldn't deal with the AT&T SIM very well, and wouldn't register on the network.
Have you upgraded to the latest radio available, or is it still running the original? Remember, most ROMs do not have the radio stack as part of the upgrade image, it's a separate process.
(I really should look for parts for my angel and bring it back to full production level for nostalgia if nothing else. Sadly, it's got a flashing LED for the charging indicator at the moment, I think the battery I have is truly dead. I will have to look for the spare I had laying around.)

Ok, trying to upgrade the radio to 1.15 and it keeps giving me the ERROR 100: Model ID error. IS it because I upgraded the ROM to WM 6.5? And is there any way I can install the radio ROM with out downgrading?

Wow, it's been a while since I looked at flashing a radio ROM on the BA... There appears to be multiple ways now. Have you followed the directions in the wiki, available here: http://wiki.xda-developers.com/index.php?pagename=BA_Radio_1.15_Upgrade

Ok, so I upgraded the radio to 1.15 finally. And still, no connectivity with my SIM.

UPDATE: Just tried a T-Mobile SIM from my friends G1 and was able to make calls and connect. So Its must be my SIM card, for some reason....
EDIT: I just soft reset it with my AT&T SIM card in, and now it says that its connected to Cingular, however, I cannot make calls or send text messages.

Sorry for the delay...
Hmm, interesting... Well since it worked with TMo, I don't think that the phone itself is bad. It looks like it's something with your SIM. You could try a different one (know anyone else on AT&T?), or check with the AT&T store and see if a rep can look up what info they have on the phone and swap out your SIM with one that is known to work with the phone.
Right now, that's all I can think of. If I think of anything else, I'll followup, but I do think that it's your SIM that is causing the issue at this point. I've never heard of anyone having to do anything special with one of those to allow calls to be made, much less send text messages (not picture messages, which do require some setup).

T-Mobile Setup on HTC Tilt

I called up ATT and got the unlock code for my friends old HTC Tilt, unlocked and placed my T-Mobile SIM card in it which has an active voice + text + web account on it, with the default ATT Rom on it I was only able to set it up to do voice and text, whenever I tried using the Data connection for like let's say IE it would bring up a page for web2go, even after Flashing the phone with different ROMs I found on this great site and went through the auto communication setup for t-mobile, and still it only does voice + text, any ideas?
Right now here are my specs:
HTC Tilt
R: 1.70.19.09
G: 25.83.40.02H
D: 3.TPCElite
HardSPL 3.29
Let me know if you need any more info..

Call T-Mobile Support
Same thing happened to me last night. I called them this morning and they fixed it in about 10 minutes.

ok cool, so I should just call them up and they should be able to tell me what to do? or do you know how?
thanks in advance,

There should be a cab file somewhere that sets it all up for you.

I called up T-Mobile and talked with one of their non-supported device technicians (they have an entire support dept. of these guys) and it was actually on their end, they had to allow the IMEI to use the Data plan, because basically the phone was like Hi let me use the Data on the Network and the network was like what's your name? and the phone was like I'm John Smith, and the network was like your not on the list sorry.
So.. yea I was talking with a very smart tech support lady @ T-Mobile, she even mentioned these forums, she said she recommends it to people that have devices that aren't supported by t-mobile she even wanted to know which ROM I flashed onto my Tilt =)
Anyways everything is good to go now, thanks everyone!

huh? I don't know what that means..

I have an issue. I just switched my entire plan over to the even more plus. On my old plan I had tzones and it works great for everything. Now I have the web2go. The problem is not getting the device to work on the internet2.voicestream.com, that works fine, but it is the battery drain. In a 4 hour period it will kill a full battery. When I remove the internet2 setting then the battery lasts all day. anyone else see this issue. BTW I'm using the JJblaster 23518 and radio 1.70.18.02
what do you all think, a bit odd for it to drain the battery that fast?
