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.
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.
Hi guys,
I have an unlocked Vibrant from TMobile, using it on WIND in Canada. On the first day with a WIND SIM, I was able to see the WIND network, and use data as expected. Then I went to school (outside coverage) and the phone roamed to the "WIND Away" (ie: Rogers) network, as expected. However, when I re-entered the coverage area, I could no longer see the WIND Home network! I've been stuck on roaming for a few days now, and I just can't see the home network. I've scanned the for Network Operators a million times - all I see is WIND Away!
My girlfriend has the same phone, and we got her unlock code yesterday. After unlocking, she was immediately on WIND Away, too. I don't see others complaining on the WIND site, so their network must be up. What could cause this? Does Android cache the network operator list, or do some sort of automatic filtering that I can disable? This is getting pretty frustrating.
Thanks!
edit: Oh, I've tried power cycling and removing the battery.
Bump?
Also tried a factory reset... What could cause the phone to simply not see a network that I know is present and that it used to see? I live less than a block from a tower.
I googled and can't find a download for verizon 2010 PRLs. Anyone have a link or can rip it from their phone??

This is the Sprint Evo forum. Maybe try a Verizon forum?
I was thinking someone here already had it ripped out of a verizon phone for their use on the Evo too
HERE are a few Verizon PRL's I keep around. There is a 51926 in there, I think from June or July of this year. Also some 65 series PRL's, but I haven't used any of them. I can verify that at least in Vancouver, WA I get great voice and 3G signal with the 51 series PRL's, cant really tell the difference between them, 518, 516, 517, 519, all good for me. Roaming triangle taunts me the whole time though,
Also, link in my sig for some other PRL's for the VZW 3G hack.

Thanks but i've tried 25 roams through out the month with altel/verizon and I always get 1x with 1 BAR. the only difference is some PRLs show the roam sign and others don't. This one even gave me the Roaming symbol.....What could the problem be????
I really don't know what the issue could be. I know that all the PRL's I linked will roam on 3G, so ???

Well they jump back and forth from Evd and Evdo_A when I sit the phone with 1 bar. But if I try to use the phone it jumps back down to 1xrrt with 1 or 2 bars at times. I'm kind of new to the hacking scene but I think everyone thing is good on my end. Unless there are other things you suppose to do after changing your PRL?
I'm no hacker myself, so at this point I don't know what else to look at.
Whenever I run any of these PRL's, I always have my network set to Sprint only, I turn off data roaming and make sure always on mobile data is enabled. But, even at the worst, I get intermittent data loss, but never get anything other then 3g. Have you tried the 00001 and 01337 prl's from the roam hack thread?
For me, on CM6.1, if I run any of the verizon PRL's, and select Sprint Only in the wireless networks menu, I roam on VZW 3G. If I switch to Affiliated Networks setting, I will drop all signal cause it gets confused I guess. If I change back to a Sprint PRL, and Affiliated Networks, I get good voice signal, but show 1x for data. As soon as I put it back to Sprint only, my data returns to 3g.
On any new froyo sense rom, it's almost impossible to tell. A bug that seems like it may be intentional has popped up. My phone will not show 1x, but only 3g. Even when I'm on a sprint prl, and confirmed to be roaming, which would be 1x, It still shows 3g. I dug into the rom, and the icons are there, they just don't show up on a lot of sense rom's
How are you able to tell what evdo ur on? Are you on an Evo?

Theres a app called Cellumap and Phonestatus in the marketplace. It tells you the network your phone is on and cellular provider.
I'm using the sprint lovers CUSTOM rom. I guess I'll switch to cm6 custom rom like you are using and set it up like you mentioned. so I'll give this a try tommorow(sunday) and report back. but I think it's just the RURAL area I live in but then again Verizon has full coverage according to their map...
yeah, probably just ur area. You should call Verizon and tell them about the issue
You could say something like, "hey, I'm trying to use your expanded 3g service for free, but all I get is 1x. Can you give me an ETA as to when this will be fixed?" That would be fun!
I'll give those apps a try on my end and see what I get.
Well, I'm getting EVDO rev a on most of these. Provider shows digital roaming but still says Sprint. Confirmed speed tests at just under 1mbs and dialing a number without area code sends me to Verizon error message.
That is with the 51 and 41 PRL's.
Hey... This thing makes phone calls too!

Aw great for you ... well I'm installing this cyanogenmod6.1 custom rom and see what it does on a different rom I guess. If not I don't know what else I could, probably no roaming agreement with Verizon(altell had my area covered before Verizon bought them so Verizon really never had towers here....)
Ah, so that's why you were looking for the newest PRL. I would think you could get it to work with the right PRL.

Apparently, my room is the only place in the US I sometimes get AT&T signal, but rest of the time my cellphone connects to the Sprint network. I went to a couple other states on the weekend and I got AT&T signal after coming back to my room. I have LS980 and tried to install different roms. None of them worked. I get 'com.android.phone crashed' while trying to access Network Carriers. Please help!
Do Sprint cell phones roam on the AT&T network? Is there a way to disable roaming?
