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.

Radio (signal/data) has stopped working and poor wi-fi performance

ROM: Royal Ginger 2.1
Kernel: ckisgen-1.5
Radio: 2.08.531.0
eMMC: 2.17
December 2011 to Late June 2011
Phone is working great. It was initially rooted with Visionary+, then with the gfree method. I've tired lots of different ROMS and kernels. I get 3-4 bars consistently at my house, and I get 4-5mb downloads.
Late June 2011 to Late July 2011
Annual, four-week trip to visit the in-laws in Sweden. My T-Mobile SIM card worked while roaming (and have data turned off), Wi-Fi calling works great. Phone is unlocked, so I used both our PAYG phone SIM card (through Telenor) as well as a PAYG data SIM card (through Telia). Both worked great.
However, closer towards the end of the trip, I noticed that whenever I had my T-Mobile SIM card installed, it wouldn't pick up a roaming signal (only wifi), and Wi-Fi calling was iffy at best even next to the wireless router. However, the PAYG data SIM card worked great throughout the whole trip, so I didn't think much about it.
On the final day in Stockholm, I realized that I left my T-Mobile SIM card back at the in-laws house. I would just get a new one when I get back.
Present Day
On Wednesday (7/27), I go to the T-Mobile store, and I get a new SIM card. I turn the phone on, I receive a few text messages immediately, deem it good and leave. However, while driving home, I notice that I can't make any phone calls. That is because I have 0 bars (but it is not x'd out). I also have zero indication of data (not even E).
When I rebooted the phone, I will get 1 bar starting out (and I can receive text messages during that time), but then it drops back to 0 bars after about a minute. As soon as I got home, it picked up the wi-fi signal, enabled wi-fi calling, and I got the "Welcome to T-Mobile" text message (since I got a new SIM card). I turned off wi-fi, rebooted countless times, and I got 0 bars every time. Troubleshooting with T-Mobile didn't lead to better results (one suggestion was to switch to EDGE-only connection--it worked for a while, but eventually stopped). Eventually, the wi-fi stopped working, too (even after rebooting the wireless router, and while other computers were using it just fine).
Yesterday (7/28), I eventually find some time to go back to the T-Mobile store and ask for another SIM card. This time, I hang out for a few minutes. I actually get 4 bars and a 4G signal--for a while. It drops back down to 0 bars. The employee taps around for a while. One interesting thing he found was that the option to "use 2G networks only" is always checked every time you to the Mobile Networks setting page--even after you uncheck the option and exit. I tell the employee I will reinstall the ROM, kernel, and radio. Those solutions help maintain a signal for a while, but it doesn't fix it.
This morning (7/29), I have been trying out different radios. I have tried out 2.09.1800.1, but it provided the same results (1-2 bars consistently when I have been getting 3-4 bars before). Now I'm on the stock radio (1.17​.531​.2). It seems to work okay, but it seems to drop to 0 bars every once in a while. It has also been very difficult to get a 4G signal. If I get a 4G signal, it drops to 0 bars; if it switches to EDGE, I get 4 bars.
Conclusions
I have a feeling that my phone is slowly failing. Are there any other tips I can try?
Thanks in advance, and thanks for reading.

Just call for a replacement

[Q] Stuck on "EDGE". How can I change the Network under "SIM Status" ?

[Q] Stuck on "EDGE". How can I change the Network under "SIM Status" ?
I'm running Dirty Unicorns 9.8 OFFICIAL (5.1.1) on my Nexus 4. The other day I noticed I had like one or two bars so went into Settings > About phone > Status > SIM Status and clicked "Network". Usually, there are a handful of providers to use there and sometimes changing to a different one improves my reception (This is a T-Mobile phone). I don't remember what I left it on.
Today the phone is stuck on "EDGE" under "Cellular Network Type". I tried to get back in the "Network" to check and see if I left it on something stupid, but I can't get back into the provider selection. No matter what I do, the device won't hook up to "LTE" (whatever HSPA/HSPA+ thing T-mo says is LTE). Everything worked fine last week. Haven't applied any patches or anything other than messing around with the Network settings. Any idea what I might try? Is there a magic dialpad entry to use to reset the Network?
Thanks

Same problem here with metro pcs who uses T-mobile

After a few days of this, and several chats and calls to T-Mobile, it seems T-Mobile is "working on towers" in my area and things will be like this for a few days. The situation is this according to the last phone call with T-mobile:
* HSPA+ is no longer available on the towers in my area
* LTE and GSM (Edge) are the only supported modes
* LTE is not supported on the Nexus 4. tuff-shizz. buy a new phone.
Ok well this sucks... so here's what I did in the past couple days.
* Installed Chroma ROM and the the LTEEnable zip file thing floating around all the forums here.
* Found out Chroma was a rebranded AOSP ripoff so uninstalled it.
* flashed Dirty Unicorns 6.0.1 to my Nexus 4, bluetooth seemed funky so flashed the .33 radio from "dmitry" ROM that I found on several threads. Also flashed LTEEnable zip, not sure I needed it. LTE now working.
* dialed *#*#4636#*#* and went into "Phone Info"
* Network Type: "LTE"
* Set Preferred Network Type: LTE/GSM (PRL) -- originally had this set to "LTE only" but no voice calls could go out, or come in.
You would think this is the end of story, but wait. Voice calling takes 20 seconds to connect (even voice mail). With "LTE only" settings all incoming calls go directly to voice mail. never even rings the phone. Are you shizzing me?? With "LTE/GSM (PRL)" the phone waits for 20 seconds to drop from LTE back to "Edge" before the call finally hooks up.
Today, found out nexus 4 doesn't do VOLTE (Voice Over LTE). at least thats what google said. That would explain the Drop to "Edge" when dialing out.
Thing is, I tried this with a NEXUS 5 on my account, using two different sims , running stock Android Whatever on the N5 and it does the EXACT SAME THING. dropping calls to "Edge" before connecting. Takes 20 seconds to dial out. Incoming calls on LTE (which the n5 runs by default) all go to voicemail.
So it seems the workaround now is to dial the "magic number" above and set the "Preferred Network" to "GSM only" (Edge). That's the only way to get phone calls in or out of either device on T-Mobile's network today. Don't bother trying to Google anything though because it won't re-connect to LTE to do it. On either my hacked N4 or the stock ROM N5. You may as well be using a dial-up modem to get any data through either phone.
So, in the end, I don't have anything screwed up under "Network Settings". I'm stuck in "Edge" mode because Tmo is updating towers for LTE. It remains to be seen if I have to upgrade both and N4 and N5 to stay on T-Mobile however. The next few days will tell. I still think this is a bit of a ****-move on T-Mobile's part. Especially if I have to upgrade the N5. It's an expense I wasn't planning on. They could at least kick in some rebate to help out with the cost of new devices. No idea if it would save any money to switch carriers at this point.

International roaming isses

I'm on vacation and I took lg v20 and glaxy 7 with me. As soon as I landed in Aruba my galaxy switched to roaming and worked just fine but v20 didn't. I tried to force roaming but my v20 connect to roaming and stays connected 2 sec and disconnects - it is in that loop since yesterday ( very 2 sec goes roaming to full bars and then 0 bars ) I tried to ##78726# and PRL and profile update and nothing helped. I called techsupport but they are useless. Any ideas ? Is my roaming radio dead ?

Dropped calls in Sweden

I have two units of the mi A1 both behave the same way. The unit drops signal and moves to another net and drops call.
By entering *#*#4636#*#* chose Phone Information I can choose network type.
By default it is set to TD-SCDMA/CDMA/UMTS. Since I'm in Europe I would prefer something that started with LTE/UMTS or something like it, but it doesn't make a difference. It still drops calls. And when unit is rebooted it goes back to default again.
Anyone who has an idea about the dropped calls problem?
Henrik

No one else have problems with dropped calls?

I have the same problem.

I had some kind of similar problem this weekend. The phone is up to date and worked fine for almost 3 weeks. Suddenly the phone started to drop calls like I wasn't able to place any call, also when called me back I was getting out of network message. In the mean time I was able to use 4G network placing Whatsapp calls. First I have restarted the phone, then tried to reset all network settings. Nothing helped. Then I have entered the service menu with *#*#4636#*#* and selected Phone info. Here you can set the preferred network type. I have tried out several combinations until I have managed to place and receive calls with following settings: TD-SCDMA/CDMA/UMTS. Maybe It was a network related problem, I don't know, arround me all other phones worked fine. What I have noticed, when I have placed a call the network displayed 4G and it should switch to 3G during call. No Volte offered yet here so it must place a 3G call. After playing with settings this working as it should.

Did the settings save after reboot? I'm still having problems.

I still have TD-SCDMA/CDMA/UMTS after reboot. I don't know what were the default settings.

Henrik, did you come up with a solution? Fellow Scandinavian here with the same issue...

Somewhat strange... I'm using my A1 in Sweden as well.
During quite long calls (10-25 mins) I haven't had any 'dropped call' this far.
I'm having 2 SIM cards (1 private, 1 work) in mine, both Telenor.
Edit:
On Stock 7.1.2 Dec 17 ROM, not modified/unlocked or rooted!

Hey fellow swedish,
I am also considering to buy that phone.. Did you manage to find any solution? Do you think that worths it buy it?

I think people in this thread have some ****ty MVNO with service from several carriers, and when the mobile switches carriers, calls drop.
If you're in a major carrier then such switch never happens so there are no dropped calls.
But I might be wrong of course.

That's weird.
I noticed that whenever I'm on 4G the calls usually drops out. If I have it set to 3G I don't seem to have any issues. I tried to set it to LTS/UMTS auto (PRL) but it goes back to stock setting when I reboot.
I had a Sony Xperia Z3 Compact before and I never had any dropouts so I don't think it's a carrier issue... What does yours say in the Phone info JockeSve?

Voice network type: LTE
Data network type: LTE
Set Preferred Network type: TS-SCDMA/CDMA/UMTS

it is dropping the calls... is it phone? or just toy?
