Force Alltel Roaming on Verizon XV6800?

Hi all...
I live in Verizon land, work in Alltel land. I have a Verizon XV6800 that works just fine in Alltel land, including inside my office building, up until a few weeks ago.
The company reciently installed a big indoor repeater system for cell phones, but they only installed modules for Tmobile and AT&T, since that's who our corporate contracts are with. My XV6800 used to sit happily on Altel's network, as long as I wasn't in the basement of the building or something, but now it is stuck on Verizon. Now I get 5 bars of Verizon service at my desk, but I can't make or recieve any calls.
Best guess from the tech guys is that the building repeater system is picking up a VZ signal from the same direction as the antennas are pointed for ATT or TMO, pulling that into the system, and repeating the "carrier" for Verizon inside the building. But since we aren't transmitting to Verizon, the phone can't talk to the network and the network can't talk to the phone.
I can't hear you now.
So long story short, I need a way to force the phone back on to Alltel's network. I did search first, but all I could find was references to Settings->Phone->Services->Roam which I don't have. I don't have Roam in the services menu. I do have Network Settings, but the only options are Auto and Home Only... I need Roam Only.
Any ideas?
Thanks!!!

You can either edit the registry and ad a D word name & value for roam only, or you could cheat and upload an Alltel prl (30031) from www.corolada.com/prl and select "home only" in your network settings.

Forcing G1 to Roam

I'm going camping this coming weekend to a place in the mountains that tmobile has very poor coverage in. I was there last month and discovered my friends at&t phone had full service while my g1 showed service, just didn't show any bars and other times only showed one bar. Calls with my phone were flacky and dropped out, his worked perfectly. Is there a way to make my phone switch to roaming on at&t?
I have a national plan on T-Mobile.
I'm running Cyanogen 3.9.5
Thanks!

Should do it automatically. I saw my phone do this the other weekend when I was travelin. My phone showed ATT, Corr Wireless, and some other service and certain points.

The tmobile signal is just strong enough to keep it from roaming there. I was hoping it would switch automatically but it never did. I know the phone does have roaming ability, i've seen it switch to roam and work fine.

I would assume then just change your APN settings.

you can try manual operator selection, by going Settings > Wireless Controls > Mobile Network Settings > Network Operators > Search Networks then select whatever network you want to use

Hi.. I'm using CyanogenMod 3.6.8.1 on my HTC Dream and I've got the same issues with roaming. I've travelled to 3 countries last month and I had issues with connecting to GSM network.. There was error message that my sim card cannot work with specific networks.. I've tried to use auto connection and I've tried also to connect manually to specific networks, but with the same result. I've tried also rebooting and removing the battery... Problem disappeared after few hours... I had this issue in Austria, Hungary and Turkey so it's not operator/country specific. Problems doesn't exist on different cell phone (Nokia). Everything works fine after powering on the phone.

Reason for "SIM does not allow a connection to this network"

I remember people talking about this on the G1 forums and people were thinking this was a bug in the Android software. I do not know if anyone has provided the answer to this already, but I figured I would share what I have found. (I also posted this in the G1 section)
Turns out that tmobile and at&t have dropped their roaming agreement in several areas. The "not allowed on this network" message is due to the phone trying to connect to these towers. Even when selecting "select auto" or selecting a weak tmobile tower, because it fails connecting to the weak tower and then will try to connect to the stronger tower (att) but is not allowed.
This whole thing sucks though, because I have a metal roof that kills my tmobile signal, but I am able to get a weak att signal inside.

negatory
I believe you're wrong there about signal strength.
I've had two seperate g1's that displayed this error when inserting a TMO and/or ATT sim. The phones were both unlocked, and sitting with 2 feet of a TMO g1 with 4 bars of 3G signal.
After updating the radios to most current and calling TMO to question someone withe sense, I was upgraded through 2 levels of customer support. The last fella I talked to apparently knew things, but couldn't say much - you get the idea. He did reset my connection (or said he did) and I watched as service for all three phones on my account died (connectivity) and then gained signal again. All while on the phone with him.
Afterwards, he suggested I clear all caches, facotory reset, etc.
Low and behold, both phones worked with 3G (TMO) and EDGE (ATT) just fine afterwards. Now, was it something HE did exclusively, or a combination of his 'reset' (whatever it was) AND my factory wipe of the phones ? Got me.
I WILL BET YOU A COKE IT HAS SOMETHING TO DO WITH UPGRADING THE RADIO TO CURRENT -AND- WIPING. If i'm wrong, i'll paypal you coke money... but I think I'm right.
If a tmo person in the know, -not a speculator-, would like to grace us, that would be cool.
This has worked for a total of three "Your SIM card does not allow connection to this network" type error'd phones. All of which were unlocked, rooted, and running cyanogenmod latest.
2 cents.

I contacted Google support about this. Apparently if T-Mobile has property rights to the area where you're connecting you are only allowed to connect to T-Mobile's network no matter how poor or lack of signal there is.

Yeah, I tested this myself, tried to connect to the only tower available (an att) and was not allowed. I know you have the roaming issue is you ever see "emergency calling only" in the service bar. Means it has a signal but is not allowed to roam on that signal. I have a good signal outside and in parts of the house, just not where I am the most. There might be a bug where it gets stuck trying to connect to the wrong towers, but the source of the issue lies in the lack of access to att towers in many areas.

EDGE Networks going away?

I read today that AT&T is planning to shut down their 2G towers by 2016. I'm wondering if other network providers are doing the same thing. If so, of course, any old Wizards won't be able to get online over the cell network. I don't use my Wizard often anymore, but still I'm sad.

[Q] Force roam on specific carrier

I'm an AT&T subscriber with a us based I337. Rooted, stock NC1. I'm currently in Canada, North of Toronto. . My phone seems to significantly prefer roaming on the Rogers network, which gets very poor service in my area. Most of the time, I get a tiny bar of G or E network. Sometimes, the Rogers signal weakens enough that I can get on the Telus network, which is great. My wife (unrooted S4 Active, at&t) is mostly on the bell network, which seems good. I've tried making the Telus apn (found elsewhere on this site), and I cannot change the network setting away from Default Setup in Network Operators. I've tried dialer code *#2263# which results in "RWT selection option is restricted".
Please help - I'd like to either force it onto Telus, or force it off Rogers. How can I do this?
Thanks
