I was able to purchase a US Cellular TP2, running the original ROM, at the Philippines, which I've been using there for quite some time under a local GSM provider without any connectivity problems whatsoever.
Right now I'm here in California, attempting to use my Philippine provider's roaming service. I was instructed to shift to manual GSM selection and select the network of my choice. However, for some unknown reason, no GSM provider shows up.
When I try the manual selection back in the Philippines, all the providers show up. How come here, nothings turning up? Any ideas on how I can resolve this issue?
ROM version: 2.01.573.3
Radio version: 2.18.02WV

I'm noticing most of us are on the AT&T Network, yet there are those that do not want or need 3G/3.5G and want to use 2G or have another carrier so they cant take advantage of the speeds because they are on a Network such as T-Mobile.
Obviously someone using primarily or mainly 2G will see significantly more battery life.
This is good for someone that rarely uses data service or goes online using WIFI for the most part.
To change or edit your Preferred Network type go to your Phone app
then enter the following: *#*#4636#*#*
>Phone Information
>Set Preferred Network Type
Now you are able to change and edit the way your phone looks for and uses the Network you are currently on.
The Terms are explained below:
Preferred Network Types change the type of frequency the phone searches for.
Android is used on several devices that can gain access to different cell carriers.
For simplicity, there are two main types of cell carriers, GSM and CDMA.
The following popular data communication technology is associated with each cell carrier type:
GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}
CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}
Now that the general stuff is out of the way, here's my take on the Preferred Network types:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best.
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this
When using the 'only' options you should still be able to make calls.
To put things into perspective, The Nexus One is set to WCDMA preferred as default and the Droid Incredible is set to CDMA auto (PRL).
My Samsun S does not recognise my sim.The sim works in another phone. I tried to change the preferred networkto CDMA preferred, as it is on "unknown". It does not allow me to change it. Please help, as this new phone is now doorstopper.

This option has not worked on any Sense ROM I have tried for the HTC Inspire. It works great on CM7 but does nothing but stay on 3G on sense.
For sense Rom if you are rooted this is how you do it
From today screen
1. Hit menu
2. Click settings
3. Click wireless and networks
4. Scroll down to mobile networks
5. Choose network mode
6. Change to gsm
This will lock you into edge only. Even after reboot settings will stay phone must be rooted or it does not hold settings
If you want 3g/4g only. Set tab to wcdma only
I am running coredroid 9.4

I have tried this on CoreDroid and ARHD and no luck. Went through settings menu and used the *#*#4636#*#* options and neither one sticks. Could it be my radio and hboot and the interface with Sense?
EDIT: Going to try ARHD again and see. If not, I will try CoreDroid.
EDIT: Still a no go for either ROM...ClearDroid included. So far, I have only been able to do this via either method (plus a built in toggle) via CM7. This begs the question of whether this is a software issue with HTC Sense.
Strange I remember when I was on stock sense Rom the settings wouldn't stick. But as soon as I rooted and downloaded a custom Rom it did stick sorry you are having trouble. Here is my complete rom/radio/kernal
Coredroid 9.4 = Rom
12.56.60.25u_26.10.04.03m=radio
Lordmod 5.0 is the kernal
I also changed my build.prop settings to enable real 4g and tweaked gsm gprs umits huspa hsdpa I do not know if this had any effect on making settings stick

Thank you for the feedback. I am running the same radio. I will revisit CoreDroid again. Perhaps editing the build prop is the way to go in this case. It is the one thing I have not tried on any of the ROMs for this phone other than to rename my phone from Desire HD to Inspire (which was only on one or two ROMS). Would you mind sharing your build.prop settings and tweaks so that I can have a baseline to work with? I'll tweak from there as necessary to meet my wants.
I edited only these in build.prop
ro.ril.gprsclass=10
ro.ril.hsdpa.category=28
ro.ril.hsupa.category=7
ro.ril.hsxpa=2
Reboot twice and don't forget to backup your settings
I used prop editor to edit build.prop its easier but I don't have a link for it but I think there is a link in that thread I posted below

Thanks. I will give this a shot. I have edited the build.prop before but only for the purpose of changing device id name. I don't remember what I used to edit it but I am sure I can find it again. No worries about the backups. I kept copies of original build.prop saved plus did a nandroid right before making the changes. Never can be too careful. Will post results later tonight on whether this was success or not for locking in the ability to switch between bands.
In that thread I posted is the build.prop app 8th or 9th post down. That tweak is just for faster data speeds and I do not think it will lock u on to 2 g or 3g but who knows

No go for 2g/3g options. Have not been able to really say about faster data speeds but definitely something I will keep notes on. Back to where I started. Looks like CM will remain my ROM of choice for now.
Preferred network type set to unknown
Hi frnds.. i had accidently set preferred network type to unknown by going in secret setting by using the code *#*#4636#*#* in my Micromax A54 and now my real imei number is changed into 00000000. My mobile is not recognizing any sim and on notification bar it says ''searching for service''. I am not able to reset previous setting i.e. unknown to gsm auto(prl) or gsm only or wcdma only. Please help me how can i resolve my problem.
Your help will be appreciated. thnx in advance..
hi i have samsung note2 my network show unknow but every thing is ok call sms is fine how to i fix it to my network when i restart it they show gprs but when i call some one they going to unknow
Turns out the device has two SIM card slots - one strictly for GSM, another with WCDMA support. If this is the same for you, change SIMcard slot and the preferred network type will change

Hi, here's a tutorial on how to change network modes using AT commands: http://www.josemauricio.net/?p=486
When i try to change my network it automatic changes to wcdma preferred.
When i try to change my network it automatic changes to wcdma preferred
I'm on PD1 6.0.1 with a G920R7 nTelos. I rooted using CF-Auto root, flashed TWRP for the g920p, and installed the zip file from this thread... http://forum.xda-developers.com/showthread.php?t=2394689
After that I installed Phone INFO ★Samsung★ and used it to access the hidden menus. Went to the 2263 menu and set all band preferences to all and selected the LTE/GSM mode only, then went to the 4636 menu and set the radio to GSM/LTE (prl) auto. I've tried GSM only and it switches back to GSM/LTE (prl) auto on its own.
I now have access to a mess of options in the network mode selection screen in settings, and setting it to GSM only and 3g only still does not allow me to catch signal. In network operators it shows AT&T, yet if you try to manually select the network it never goes through. *#0011# still shows it switching through LTE bands and not staying on one or registering on the network. In the device info screen (4636 menu) it shows the correct phone number and AT&T for current network, but under cellinfo still shows it switching between LTE bands and under GSM disconnects it shows ======DATA======.
At this point I'm not quite sure what to try next. Please let me know if anyone has any ideas to try. Thank you.
EDIT: I've also tried the G920P domestic unlock and G920R4 unlock with a box, but no luck with either as expected.
i can do remotely if u want

I have a box but the device isn't supported, it's not locked I must just be missing something. Anyway you could private message me what I'm missing? I've been through all the settings messing with it and all, even flashed the CDMA to GSM zip floating around here. I know I'm missing something silly. Any help would be appreciated and I don't mind sending you a donation provided I can do this myself next time.

I just messaged him on Hangouts. I don't know if its something he can help with or not because I believe we have the same box and the g900r7 isn't supported. This isn't even answered on that Voldemort website.
Did you figure this one out? I'm also interested in GSM unlocking this phone.
Messing around with it I was able to get an ATT Sim card to pull 3g data but no call/text or lte.
I'm customer of the local carrier "Drei" (Hutchison) but my Pixel (bought in Germany) does not connect to the 4G / LTE network.
The support of Drei is not able to help me. LTE is working fine with the same SIM on the OnePlus One.
Any clue how to fix that?
There is regional problem I came across. In India here we dont have VOLTE support on pixel

What LTE bands do they use on Drei?
Same happen to me in Portugal with MEO. I can't seem to solve it. Talked with my carrier support, they don't know why I don't have 4G/LTE.
I never got 4G, but my SIMCard has no issues with iPhone getting 4G right away.
Is it Pixel issue? I start to think it is..
3/Drei is listed here: https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe#Commercial_deployments
The specs of the Pixel are listed here: https://madeby.google.com/phone/specs/
That is all information I have got.
Is there any possibility to display information about nearby LTE senders via an app?
After activating "LTE only" via *#*#4636#*#* it works. Everytime I search for networks or reboot my phone it still connects via 3G and switches back to "LTE UMTS auto (PRL)".
Seems to be a software issue.

I use the phone on Verizon and don't have any problems connecting to LTE using any available mode (Global, LTE/CDMA or LTE/GSM/UMTS). However, if I set the mode to LTE-only via the menu, it will also reset when I either reboot the phone or if I just open the "Cellular networks" menu. I think it's how it supposed to work because that menu doesn't have the LTE-only option, so it resets the mode to whatever you see there. The solution is simple - if you reboot the phone change the mode again and don't go to the "Cellular networks" menu
Regarding why it doesn't work with "LTE UMTS auto (PRL)", it might be because Drei didn't configure a handover from UMTS to LTE on the cell site you're connected to. It looks like Pixel finds UMTS signal first, but doesn't know that LTE signal exists due to a missing handover. Another phone might be fine if it searches for LTE signal first. But if you can see another phone switching from UMTS to LTE in the same spot, my theory is wrong.
I'm going to access *#*#4636#*#* and trying to explore setting around there, and I open the radio band setting, in the "set radio band mode" it's just United States listed there and so I click on it, after selecting radio band to United States my phone can't connected to 3g/2g network. is there any solution?
edit: solved. Restore ROM to COS13.1 and access radio band setting and now there's three option "auto", "EU" and "US".I set it to auto and my mobile data working again.
