[Q] Droid 3 xt862 mms/wap settings on Alltel

I've got an xt862 activated on Alltel but am unable to get mms/web configured and working. It does work on web when connected to Wifi but of course if I'm going to use this device I need mobile web. It works for talk and text but no mms and no web.
I had to manually put in the MDN/MIN in order to get my number programmed. I am in one of the few areas where Verizon and Alltel are supposedly separate. After manually programming MDN then *228 would dial to Alltel prompt as opposed to VZW's prompt before I programmed manually. The phone seems to have the vzw stock rom.
I am switching from a Motorola a854 (defective screen). I copied any programming settings from the a854 to xt862 that I could, even if they weren't necessary(IMSI, country code, etc). I did an APN Backup and Restore from my old device to the new one, and also tried an APN Backup found online supposedly for Alltel devices.
Sorry for the noob post but I've searched multiple forums in an attempt to get any resolution to this issue and wanted to avoid creating my own thread.
Any assistance would be appreciated, I do not foresee any world traveling in my future so standard CDMA connectivity is all I'm looking for.
Thanks in advance and sorry for long post, tried to be brief while remaining thorough.

huhu, if the apn restore worked u maybe just need to tick the checkbox
to activate the apn
settings->wireless & networks->mobile networks->access point names
if there is no entry u have to add the APN manually

Thanks for assistance, but I'm with Alltel (CDMA) and this device only allows selecting APNs in GSM Settings. When I Change Network Mode from CDMA to GSM or Global it will then show no service alltogether. I'm still trying, I feel if I could get the proper APN then I would be ok but I'm not sure. Thanks

Droid 4 On Rogers Wireless (Canada) - Incoming "Pay Phone" caller ID Solution

Droid 4 On Rogers Wireless (Canada) - Incoming "Pay Phone" caller ID Solution
I recently got my XT894, Droid 4 in the mail, and hooked it up to Rogers Wireless in Canada.
When I was receiving phone calls, the built in dialer would tell me that "Pay Phone" is calling, the solution to contact the Rogers Customer Care, and have them remove the "Name Display" option.
Rogers has 2 services for call display:
Name Display (which does a phonebook lookup from Roger's Side)
Call Display (the number of the dialer who is trying to dial you)
Most motorola radios don't actually support these 2 features together, so Blur reads it as "Pay Phone". After contacting Customer Service, have them remove ONLY "Name Display". I restarted my phone then everything started working properly again.
I hope this helps someone!

First off, I wanted to say that I'm on the leak 6.16.206
I also got mobile hotspot working on Rogers (this solution may apply to other rooted users running on different providers).
I added the APN settings as defined originally here: http://forum.xda-developers.com/showpost.php?p=20366961&postcount=2
Name: Rogers Tethering
APN: isp.apn
MCC: 302
MNC: 720
APN type: dun
otherwise, any other fields are showing as <not set> OR None
When I tried to add dun to the apn type, the moto UI told me only providers could add DUN types, so I went into SQLite Editor -> Phone/Messaging Storage -> telephony.db -> carriers -> Located the last APN which I added manually, scrolled over to "type" then long pressed that field, chose "edit field" and added dun. Once completed, I restarted my phone. I now have the stock mobile hotspot app working (I had to also disable the entitlement check earlier) on Rogers!

Now wait, you got a Droid 4 working on Rogers????

Yup, no LTE though, just GSM HSPA
Sent from my XT894 running ICS

I can confirm that the Droid 4 works on Rogers. Took a week of fiddling, but it works.
Received the Droid 4 with 2.3.4 installed. Did the over-the-air updates to 4.0.4. Rooted it, installed SafeStrap 3, and installed Olegfusion's CM10/JB ROM (4.1.2), and was off to the races. Shows "E", "3G", and "H" when accessing the Internet.

have you ever try with stock kernel?
I wonder not to update to CM10 right now. I have a problem, it seems to connect, 3G/H letter, bu no tranmition. I have an old jaj, Droid3 working perfectly with same APN records.
Any thing that could help me??

LTE on this phone is not compatible with the Rogers network. If you want a Rogers LTE phone, pickup the Motorola RAZR HD. The phone will operate on 3G or 3.5G, although we in Canada consider HSPA+ to be "4G".
LTE can give you rates of up to 100mbps usually gives you about 25-30mbps
HSPA+ can give you rates up to 12-15mbps I usually get 4-5mbps
I hope that helps!

how hard is it to get Droid 4 to work with Canada (Rogers)?
Do u have to have unlock it and then update to ICS, and then you're all set?

The phone comes unlocked, you just have to load up ICS and throw on the Rogers APN (rogers-core-appl1.apn) and you're good. If you want to do some of the advanced features like setting up wireless tethering and stuff along those lines, you'll need root.

so you're saying that all droid 4 are already unlocked?

Yes. They are still blocked against US GSM carriers but will work fine everywhere else, no locks.

Maybe someone can help me, I'm on Rogers. I have this same issue on Stock ICS .217 and on CM10. I can make phone calls and send text messages, but I cannot receive either. When I put my sim card in to another phone, I start getting my text messages. Any ideas on how to remedy this?

Have you tried another SIM card in your phone? Sounds like you have something wired. I would also check to make sure you are in global mode on the phone.

eBay, yes.I got mine as "bad ESN" from a liquidator, it was quite a good deal. Obviously, by now you can find clean ESN versions for below $250.
Anyways, I am on Koodo/Telus. Under Mobile Networks Settings / Network Mode set GSM/UMTS and Select Network must be UTMS only, the default finds GSM which is weird because Telus AFAIK does not even have a GSM network! It has CDMA, HSPA+, LTE even iDEN but not GSM. Before I forced UMTS, phone calls worked more or less but mobile data rarely. Since I forced UMTS I get mobile data everywhere, inside buildings, all that -- I had lots of reception problems with Wind Mobile, Telus is infinitely better.

I went through the process today and got my stock Verizon 217 Droid 4 working on Telus. I verified the Telus APN settings, went through forcing GSM/UMTS and UMTS-only mode, but still have terrible reception: 1-2 bars, -100dbM. Any thoughts for getting better signal?

[SOLVED] DROID 4 Canada SMS/voice only, no data on Rogers/Fido - help!
SOLVED! see below.
Droid 4 from Ebay, $135 or something + shipping. Replacing my string of bad luck with i927's from smartphone_wholesale (aka Cell Phone Forever) on ebay (tho the 1st one they sent was great til i lost it).
SMS/Voice is fine but cannot do any cell data on it. Following all settings on fido's site for APNs the fido-core-appl1.apn doesnt work. Had to manually put it in (APN list was blank). Tried my wife's Roger's sim, it populated the APN list itself (4 of them, all combos of internet w or w/o MMS, and rogers +/- 'internet' in the name). None of them work either (they match what's in the fora here and on the rogers site, rogers-core-appl1.apn etc).
Im a bit of a newb: is my phone not unlocked properly or something? What gives? Radio is set to global or GSM/UMTS (CDMA doenst work of course). What's the solution here?
System version: 98.72.18.XT894.Verizon.en.US
Android Version: 4.1.2
Baseband Version: CMDA_N_05.25.00R LTEDC_UI_09.1D.00

Build #: 9.8.20-72_VZW-18 Feb 8 13:11:57 2013
yes mobile data is on (and roaming set to yes but phone states it's not roaming now)
every time i've added apn's and saved i've rebooted (and rebooted twice with wife's SIM in too, in case settings had to go sim -> phone + reboot, etc). No luck any way ive tried.
Thanks for help.
[UPDATE]
belay that request cadet!
Ok I just removed the wife's sim and put mine in, rebooted, and this sim (fido) doesnt populate the APN list. I was in the middle of inputting settings for it, hadn't finished and a buncha text+ came in and wifi is off (I saw I was on Edge, big blue E on status bar). Then before I could even react I had hit save, and data turned off.
Yep, removing "internet" from the APN 'type' works fine. Leave it blank.
W t f. Maybe someone can explain that shiz to me.

[GUIDE] Using I537 on T-Mobile and other AWS Networks

So I'm writing this guide for SGH-I537 (ATT Samsung Galaxy S4 Active) users who want to use their I537 on T-Mobile or other carriers that support AWS (Advanced Wireless Services; see: http://en.wikipedia.org/wiki/Advanced_Wireless_Services).
Initially I got my I537 and heard conflicting reports of DIY SIM unlocking being successful, supposedly some people unable to get the AWS bands. So, I played it safe and got the device unlock code straight from ATT. Everything seemed to work at a cursory glance, got LTE and fast speeds, great! Little did I know that I actually did not have AWS unlocked.
In my room I get nearly no reception and rely on a repeater to get signal and be able to do basic things like SMS, make calls, etc. I noticed that for some reason the I537 was not picking it up.
ATT runs their LTE over some TMO HSPA frequencies (AWS) and the phone by default won't do HSPA on those frequencies. An AWS unlock will allow the phone to do either LTE or HSPA on these frequencies, thus allowing it to talk to my repeater.
I followed the guide at http://galaxys4root.com/galaxy-s4-t...aws-bands-on-att-galaxy-s4-sgh-i337sgh-i337m/ but instead used the UMMS code of *#0808#
It works on the latest stock, unrooted ROM. My device was already SIM unlocked but I don't think that will make a difference for this process. I believe that one would require SIM unlock regardless, though, to use another network.
This guide unfortunately depends on Windows specific tools, so I had to use a Windows machine to do this. It's a pretty easy guide -- basically you tell the phone to expose its modem over USB, use a Qualcomm program to talk to it, do a backup of the NVRAM, and NV Restore someone's I337 NVRAM that has the AWS enabled.
It works perfectly for me and has worked for others as well (see comments on that guide). The only difference is we have to dial *#0808#
You may want to add the T-Mobile LTE APN as well:
Code:
Name : T-Mobile LTE
APN: fast.tmobile.com
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS Protocol: WAP 2.0
MCC: 310
MNC: 260
APN Type: default,supl,admin,dun,mms

EDIT: Did you go to Device Manager, and see the two Samsung COM ports? Then in the QPST tool, did you add those ports manually? Otherwise QPST wil always say "No phone"

Very strange. I wish I knew the ansewr to this I stumbled upon the AWS unlock guide for I337 long time before I bought the I537. I guess I was lucky that it went without a hiccup then.
And you have the special Samsung drivers installed from that site and are sure some other drivers aren't trying to pick it p? =|

I would like to add that you should change the apn name to fast.tmobile.com (from epc.tmobile.com) that's how enabled 4g LTE in my city.
I would like to ask a 'stupid' question is there a way to enable 3g? It seems to be either edge or 4g/4gLTE for me, I've never seen my phone have a 3g icon.

For T-Mobile it's not going to show 3G afaik, it will default to showing 4G for any 3G or HSPA 4G mode. If you have LTE enabled (any of the LTE modes) then it'll show the 4G with "LTE" under the bottom right side. I leave my GS4A on T-Mobile with WCDMA Preferred which seems to offer the best speeds and connections. While T-Mobile is still working on their system here in Vegas and making improvements, the LTE aspect is of no use to me and just allows me to burn up my 5GB that much faster.
To change the modes you'll have to go into the *#*#4636#*#* menu and do it, again afaik. It's the least hassle free method I've found for myself so that's what I stick with.
And I've never changed the APN from epc to fast - it's worked since I did those same instructions to enable the AWS capability. I did change it one time but the speed tests ended up being effectively the same no matter which APN I used so I set it back to the default of epc.tmobile.com and have yet to have any issues.

Yeah, good call, I'll add the APN settings to this thread.
We have LTE in San Jose and San Francisco and it's REALLY fast and way better than the HSPA+ network. And it seems to switch to HSPA+ just fine if there's no LTE.

Added TMO LTE APN settings.

while the process went without a hitch for me, I did not see any improvements
I was getting 4G both before and after, no LTE
in fact, the speed went down fron 2.5MBPS to less 1MBPS !!
So i flashed the AT&T backup back!
might be cause I am in Seattle area
(it shows HSPAP:15 in the status in either case)

HSPA isn't LTE, you have to enable that aspect manually. By default when you put a T-Mobile SIM in the GS4A it'll set itself up for GSM/CMDA usage, and you have to alter that to get the LTE working, at least I did in my case.
I went into the service menu using *#*#4636#*#* and changed it from GSM/CDMA auto (PRL) to LTE/GSM auto (PRL) and you should reconnect and get the proper 4G/LTE symbol noting the type of connection (4 with smaller G above the letters LTE).
Here in Las Vegas that's all I have to do to enable LTE (it'll show as LTE:14). I don't use it because the actual LTE signal strength is like -105 dB here at home; when I switch it over to WCDMA Preferred it increases to -78 dB and the speeds are very fast with HSPA:10 or even HSPA:15 on occasion, and LTE drains the battery more as well (in my testing).
That's my usage and experience, maybe making some alterations with your service menu can improve performance for you. T-Mobile is still doing the upgrades across their whole network so, what might have crappy signal coverage now might improve soon.
My suggestion is try each of the potential connection methods and find the one with the best signal strength and the best speeds - for me, again, that turned out to be using WCDMA Preferred, and I'm right across the street (line of sight) with a T-Mobile leased cell site, just about 1200 feet from me with nothing in the way either when I'm here at home.
Also, I've never had to edit the APN info on my GS4A for use with T-Mobile. I know the recommendation is to alter it from epc.tmobile.com to fast.tmobile.com but since mine works just by altering the radio connection and ends up getting the same speeds (I've tested both APNs), I just stick with the default of epc.tmobile.com and I haven't had any issues worth noting. I did read some comments that said in some areas to get the LTE working properly you DO need to use fast.tmobile.com, but for me I haven't - could be something to check into for yourself.

Got LTE running on the opposite corner of my building, with abysmal speeds!
the LTE coverage in Bellevue/Redmond seems to be either very spotty, or very incompatible with S4A, not sure which it is... but overall the internet speeds are better with HSPA+ than LTE in any case...

SIM Unlocked on T-Mobile in Orlando:
Before Samsung replaced my Active I was running MF1, this hack wouldn't work. They sent me a new replacement with MF3 Monday. This worked!! Places where I get "E" are now "4g"!!
Awesome! I was almost going to sell it for a Nexus 5 due to this problem but not anymore!

So I've gone through all the steps and now I am at the part where I add the APN but I can't seem to find the MMS Protocol section. I've also heard we should use fast.t-mobile.com instead of the fast.tmobile.com, would that matter??

[Q] Network issue

Hello Team,
i purchased a unlocked HTC one and i use a AT&T gophone sim card. i am not able to get the LTE signals so i would like to know is the phone capable or its an issue.

This happened to me a few months ago. The phone is definitely capable and you will get LTE signals on the $60/month GoPhone plan.
1. First of all, call GoPhone customer support (611 from the phone) and confirm that they have your HTC One whitelisted for LTE. They're going to double check with you your phone's IMEI number (they can already see it, but will ask you for it anyway), and then confirmed that the phone is allowed to get LTE signals. They're also going to double check your APN setting and provide you with the appropriate entries for AT&T.
2. Reboot and see if you now get LTE signals. If you still don't get it, check whether your mobile network settings is set to GSM/WCDMA/LTE Auto instead of GSM/WCDMA Auto or WCDMA Preferred (or maybe something else). If you don't see any LTE option, dial *#*#4636#*#* from your dialer, and in the first drop down box choose 'GSM/WCDMA/LTE Auto' or anything with LTE just to make sure you can catch LTE signals at all. If you were able to find and switch to the setting you want, exit out, and go back to that menu, double checking if the setting sticks. If it does, reboot and try again.
3. Most people will get LTE signals after #1 above, while some were only able to get it after #2. However if you are unlucky like me, the LTE setting does not show up in mobile network and no matter what I do in the hidden menu, the setting won't stick (it's stuck on GSM/WCDMA Auto). I actually tried flashing a different radio at this point (a newer AT&T radio), but still... no LTE for me. What solved this finally for me is that I flashed a custom ROM (in my case it was ARHD 12.2). This enabled me to choose GSM/WCDMA/LTE Auto under mobile network settings, and after that I was able to get LTE. It was great! :good:
Hopefully that helps. Good luck!

More data roaming problems - Verizon EVDO

I'm getting a chance to do some extended testing with data roaming. I found a couple of other data roaming problem threads, but this issue is different than the problems discussed in those.
The HTC One is rooted, unlocked, S-OFF, stock 4.4.2 (4.06.651.4), with PRL 56018 installed from CDMA Workshop. I've installed a couple of the patches floating around for WiFi tether. I also have an HTC EVO 4G LTE with the 56018 PRL installed via QPST.
Right now, I am in an area with extremely weak Sprint signal and decent Verizon signal. The EVO 4G LTE finds Verizon 3G EVDO and will voice/data roam just fine. SignalCheck verifies that the provider is Verizon for 1x and EVDO, with signal between -90 to -100 dB. However, the One will not data roam. SignalCheck indicates that the One finds Verizon for voice (1X), but does not connect for data roaming. If I watch SignalCheck long enough, I can see that the One will find the Verizon EVDO for a few seconds every five minutes or so, but it won't "hold" the EVDO signal. On Sprint, the ONE will find both 3G and 4G.
I've played around with various mobile data settings, but nothing seems to help. In fact, the One will pop up the messages that data roaming is in effect, but there is no data connection. Since the EVO 4G LTE will EVDO roam, it seems that the One should EVDO roam as well.
Any ideas or suggestions on what to look at? On Sprint the 3G is usually ePHRD, not EVDO, perhaps there is some issue with EVDO on the ONE? I thinking about getting Roam Control to see if that would make any difference. I haven't taken the 4.06.651.9 update either.
Thanks!

I had a chance to do some further data roaming testing with the One and Evo 4G LTE side by side.
Roam Control seems to work fine on the One, except that the color of the blue button for selecting the roaming mode is hard to distinquish.
Unfortunately, it seems that the One will not lock on to a Verizon EVDO signal. I found several areas with strong EVDO signal. The EVO connected just fine, but the One wouldn't. The One does fine with Sprint's eHRPD signal, and will lock on to the Verizon 1xRTT for voice.
I don't know how to do further debugging. I guess it could be a radio problem, an issue with the 56018 PRL and the One, or some other issue.
Any suggestions are welcome!

Providers dont like roaming, the newer the phone is the less likely it will be to roam, the first two M7 radios would not allow any roaming at all on my phone, the latest 2 do allow roaming but I need to force "roam only" with roam control, I am on the latest radio running GPE rom and use roam control to force roaming whenever verizon has a better signal and it works good. I am using PRL 56015 flashed via CDMA workshop.

Unfortunately, my One will not data roam, even with Roam Control. It sees the EVDO for a few seconds, but won't hold it.
Would there be any tweaks that could be made to the radio from CDMA Workshop that might affect the data roaming behavior?

I dont think you can tweak a radio, all I could suggest is make sure you are on the latest radio from here

I flashed the PRL with cdma workshop and use roam control when needed and it roams on 3G no problem. let me know if any of that helps.

I loaded PRL 56015 into the One with CDMA Workshop, but the problem remains...when roaming, the One will see the EVDO briefly but not hold it, according to SignalCheck.
I did a comparison between the various settings in the One and the EVO 4G LTE (where roaming works fine) using CDMA WS. The are significant differences, particularly on the CDMA, CDMA-2, and EVDO pages. For example, on the EVDO page, the EVO has a username ([email protected]) for HDR_User_long, but the One doesn't have one. The EVDO revision is also different. I don't know enough to fool with these settings.
Actually, the One is missing values for many settings that the EVO has. I'm beginning to wonder if somehow the One didn't get provisioned properly.
Thanks!

If you change any of them settings in CDMA workshop, save them first, if you screw something up you can reload the saved settings, I screwed with CDMA workshop alot in the past and you can do alot with it. Before screwing with them settings, did you try resetting or updating your data profile?..maybe something got messed up in the tweaking and flashing your doing. I flash all kinds of different stuff on my phone, every once in a while I flash a sense rom and update or reset my data profile just in case...

I did "update profile" from Settings->System updates, but nothing changed. What you mean by resetting the data profile?
Thanks!

I am not on a sense rom right now and I forget the codes, try entering ##3282# or *#*#3282#*#* in your dialer, it should bring up a data menu, there should be an option to do a reset, it will basically erase your data profile and reboot, when it reboots it will do an activation and reset everything....or ##786# will completely reset everything, that has saved me once or twice but that also factory rests your phone. these will only work on a sense rom and I reccoment a backup before doing anything, just in case... if that dont work do a google search for epst codes, and find the one that resets your data profile.

I did a profile reset with ##3282#, and the behavior has changed somewhat. The One is now holding the EVDO signal according to SignalCheck. However, if I try to open a web page, a message box pops up indicating that data roaming needs to be enabled. If I tap on "data roaming" in the message box, it takes me to the mobile data settings. I have been over and over those settings, and tried different combinations of things, but I can't seem to come up with the magic setting that will make the phone think that data roaming is enabled. I am forcing roaming with Roam Control.
Is there some "hidden" setting to enable data roaming? There is a "CDMA Roaming" setting that has choices of Home/Automatic, and I have it set to Automatic. I have identical settings to the Evo in the mobile data settings, but I can't make it work on the One.

What rom are you using?, I think the stock roms from Sprint no longer have the "allow data roaming" option, Sprint tries to avoid us using roaming as much as possible, so if you are on stock rom or something close, you probly don't have this option, try flashing a modified rom that may have this option, or if you are familiar with using the exposed framework, I think there is a module you can use to enable the data roaming. I personally use Gruesomewolf's GPE rom and it has the option built in if you want to try it.

I'm on the stock 4.06.651.4 ROM (rooted and S-OFF). This is my wife's phone, and I'd like to keep it stock and simple, as she's not a techie. However, she also travels where data roaming is required, so I might have to try another ROM.
Interestingly, My EVO 4G LTE doesn't have an "allow data roaming" setting under mobile network settings that I can find, but it roams just fine. In fact, the mobile data settings on the EVO and One are almost identical, except that the One has some additional GMS options. I wonder if there is some setting in a file like build.prop that affects data roaming.
I installed a couple of native hotspot hacks on the One. In looking through the zip files for those hacks to see what they actually did (which was quite minimal), some network-related things were changed in /system/customize/ACC/default.xml relative to the file in the original ROM, and a shell script was added that executes several iptables commands. I may try to manually undo those hacks to see if it has any effect. At this point, we need the data roaming more than the hotspot.

Alot of your issues can be solved with a custom rom, you wouldnt need to install the hotspot hacks either, most have native hotspot built in.

Getting a chance to work on this issue again...it seems that the EV-DO problem with my HTC One is not limited to roaming, but also occurs on the Sprint network.
Again, doing side-by-side comparison between the HTC One and my EVO 4G LTE on Sprint network:
1) Set network mode to LTE/CDMA. According to SignalCheck, both phones will find Sprint LTE and display the 4G indicator in the status bar, and both will occasionally drop back to Sprint eHRPD for periods of 5-10 minutes (displaying the 3G icon in the status bar). Network is available to apps in both the LTE and eHRPD cases. No problems here.
2) Now...change network mode to CDMA Only. According to SignalCheck, the EVO will find Sprint EV-DO, the status indicator will change to 3G, and network is available to apps. However, on the One, SignalCheck indicates that EV-DO is found (but doesn't indicate which carrier), there is no 3G (or 4G) icon in the status bar, and apps report that there is no network. The EV-DO signal is strong for both phones.
So, it seems that on the One, LTE and eHRPD are working, but there is some kind of problem with legacy EV-DO, where the phone can find a signal, but can't complete the process of registering on the network, whether Sprint or roaming.
Do eHRPD and EV-DO use the same radio? Trying to rule out a hardware issue. I am thinking of flashing a different radio firmware. Perhaps something got corrupted when I did the OTA update.
Not that Sprint wouldn't do this, but it would seem odd to put something in the stock ROM that would prevent EV-DO, even on Sprint's network. Is there somebody out there on the stock ROM who could confirm that they can get network in CDMA only mode?
Thanks!

So, I finally got this problem solved! I had to do a ##786# "hard reset". After the reset, EV-DO works fine.
The reset process was interesting. I did backups, expecting the phone to be wiped. I entered ##786# and the phone said it was preparing, and then rebooted. But it rebooted into recovery (I have TWRP). Not being exactly sure what to do, I rebooted into the system. The phone booted up, and the provisioning process started and completed. It then fetched the PRL. But nothing was wiped out. Apps, data, and sdcard were all intact. Oh, well, no complaints, and everything seems to be working fine. I used CDMA workshop to put PRL 56018 back, and roaming seems to be working.

I know you got your issue fixed and its been a while but just a heads up in case you run into problems again, I got a replacement phone from sprint and had the exact same issues youe were having, It is a problem with the data profile not being configured correctly, in my case, the new phone did not have my user name correct, worked fine on sprint network for some reason, but I couldnt get 3g in roaming areas, using epst I put my correct user name in and everything worked perfectly...dont know what rom your running now either but NUISENSE is awesome with this phone and it has "roam only" opttion built in, no need for roam control app....

Thanks for the tip!
I'm using the stock ROM. Since my last post, I have been able to test romaing, as we've traveled off the Sprint network, and roaming 3G worked fine. The only issue was that in a one spot we were roaming on a regional carrier, and the phone had locked on a quite distant tower according to SignalCheck, instead of Verizion which had closer towers. This resulted in some loss of 3G just as we were trying to get radar data for a storm we were traveling through (bad timing). But that is most likely a PRL issue. In looking though some PRL analyis an earlier version of 56xxx on another site, Sprint apparently doesn't have roaming agreement in this particular area with Verizon. I wish I new more about PRL editing so I could fix that...
