[Q] [SOLVED] Changing Frequency Band - Nexus S Q&A, Help & Troubleshooting

Hey all,
I just moved to France with a i9020a Rogers phone. According to this (http://forum.xda-developers.com/wiki/Samsung_Google_Nexus_S) my phone can cover the 2100 frequency band and according to this (http://www.worldtimezone.com/gsm.html) France's 3g frequency is 2100. I just got a SIM card and my text and calls seem to be working, however, I can't use data at all. Any ideas?
Phone info:
Type: Rogers i9020A
ROM: 4.0.3 stock
Kernel: eugene's
Radio: UCKE1

I tried following the steps below, however, after deactivating and activating my phone radio and pressing menu my phone just went back to the home screen. I remember doing this with gingerbread and having a new screen asking which country and provider I had. Can anyone else do step 5 with ICS?
1. Go to Dialer. Dial *#*#4636#*#*
2. Go to Phone information. Choose the preferred network to
"GSM Auto PRL" or "CDMA Auto PRL" or whatever you have.
3. Scroll down, deactivate and activate Phone Radio.
4. Press Menu button.
5. Select Phone frequency, then choose your country.
6. In the previous menu push the Home button to go back to Homescreen.
7. Reboot.

Gotten edge working
Update:
I have tried flashing several different radios with no luck. I did find that I did not have any APN settings so I found the APN settings for my provider (http://mobile.free.fr/faq-config-apn-autres.html) and now I have EDGE .
Since I can only have one APN configuration selected at a time how do I configure the MMS to work? Will configuring it under a new configuration work or do I incorporate it into my current configuration.
And of course I still can't get that blasted 3G to work.
Any help would be appreciated!

Solved:
After flashing my original radio (UCKE1) on my phone my 3G is now working . To configure my MMS (for free mobile anyway) I used the APN settings provided by Liel (http://forum.xda-developers.com/showthread.php?t=1452220). I hope this helps anyone who's having trouble in the future.
Cheers!

Can you set to WCDMA preferred?

Issues w/ Preferred Network Type
Sometimes but not always, when i set it to a particular preference, it doesn't stick. Sometimes i do WCDMA only but 1 minute later, i go back in and it's reverted back to GSM/CDMA auto (PRL) default....Anyone having this issue?
There is a different menu that controls the radio on the NS.
I am not sure how you get to it through the dialer.
Download Anycut from the market.
In Anycut Add a new shortcut to "testing" which is under "activity".
Open "testing" and you should be able to to elect the band type. this one does stick
Done.
Testing just brings you to the wireless/networks screen which only has lock to 2g

WCDMA only = 3G. Using a shortcut to Testing instead of *#*#4636#*#* did stick after rebooting. Thanks for the tip clubtech.
whats the difference between:
GSM auto and GSM/CDMA auto? Shouldn't we just have it on GSM since tmobile doesn't have cdma?

Phone info. In Anycut there is also a shortcut for it. Look in Activities / Phone info.
Anycut works for me...but I noticed that with WCDMA only, sometimes I do get 3G on top, but the bars go from green to grey. I end up reverting to default GSM/CDMA.
If you call *#*#4636#*#*
And go to the Phone Information ...
Can you set the preferred network type to WCDMA preferred?
Because, I cant ...
As soon as I set to WCDMA preferred, closed, and re-check, it will be back to GSM/CDMA auto PRL
Both modes are more or less the same, but auto PRL will prefer EDGA on low signal.
http://forum.xda-developers.com/showthread.php?t=688492
Yes it can. I noticed the same issue when I first got the phone but now on custom rom it stays on the wcdma preferred but still resets after a reboot. Wcdma only stays after reboot.
Ah, you use custom ROM.
But, I am using stock ROM ...

Hey are you still on CM7Alpha2? Coz I am using this and mine can't set to WCDMA preferred permanently, it still reverts to the PRL.
Can't get it to stick on mine either. Stock rooted phone. Tried using anycut as someone else recommended, still won't stick.

Same here, preferred won't stick, so I just changed it to WCDMA only. You have to reenter your SMSC number after that though.

i don't need to do that, it works when i set it to WCDMA only, and it stays
I tried to edit the build.prop as discussed in other threads
# Default network type
# 0 => WCDMA Preferred.
# 1 => GSM Only.
ro.telephony.default_network = 1

but ro.telephony.default_network wasn't in my build.prop and adding it as a line didn't seem to do anything for me, at least it didn't help with the dropdown in the phone information screen.

Same problem here.........
Did you get any issue updating SMSC?
I spent some times this morning because I accidently changed the SMSC via *#*#4636#*#*
And I could not change it back!
Every time, I got error "Update Error".
No matter what I put there:
+3112345678
+31 12345678
003112345678
3112345678
At the end, I used my old Windows Mobile, and changed the SMSC there.
It works

The number to enter there is not the phone number. Its a modified version of it, I had to load another sim card fro the same operator and refresh then copy down the number to update it back to my sim card!
Yeah, and that's the problem. In Windows Mobile, I just enter the phone number of the SMSC.
SMSC is usually a phone number.
I checked with my provider (Vodafone NL) and it is a phone number.
If it is not on Android, then I don't know what it is
I read on Nokia (Symbian), the SMSC can be entered as phone number as well.
Probably Android is not using standard format for SMSC? At least on the user interface (to update).

Weird APN / 3G issue

hi,
I'm on day 2 of trying to sort out my wife's new Captivate, so would appreciate any help at all. Phone is rooted, unlocked and has decent signal, but I cannot connect to 3g.
I'm on Optus network via TPG (Aussie network). I've tried many APN settings, and I'm at the point where I don't think this is the issue (yes, I know this is normally the issue).
I tried going into *#*#4696#*#* and doing WCDMA preferred, and WCDMA only, made sure AUS radio band was selected and did 'Enable data'.... also no help
I've also made sure data is enabled on the sim/account. If I insert the sim into another phone, it works with 3G. So it's something to do with the phone for sure.
Optus' 3g info says "2100MHz frequency band. Enabled with High Speed Packet Access technology (HSPA)". So WCDMA is the correct setting I think.
To be clear, I've never gotted the little 3G symbol at all (or an 'H' symbol that I've seen someone mention). I first tried emulating my own Vibrant's settings exactly, which didn't help.
Any ideas would be great.
thanks.
I'm completely out of options ... is there a chance this is an issue with bad contacts? I fixed my Vibrant's GPS by prying up one of the contacts...
All fixed. If anyone else has this trouble - flash back to stock, following this guide http://forum.xda-developers.com/showthread.php?t=884364
Note - I already had stock, so no idea what the hell was going on, but whatever.

Foreign Carrier Data Connection Issues [Solved]

Hey guys, I recently unlocked and rooted my Infuse 4G from ATT
Im currently living in Panama and using CLARO, I got the correct APN settings,and everything, and the internet works.. "Sometimes" I have gone to the store to obtain help incase it was something on their network, but there is nothing wrong with the network, Next I tied Replacing my sim into my friend who just got the Galaxy S 2, And it worked fine.
The problem In my case seems to be That I cannot maintain a stable Data Connection, It keeps dropping and activating back randomly, if I reboot the phone it will bring data back to it 75% of the time.. but only for a short period.. maybe 5-10 mins at most, then it disappears again.
Im just wondering if anyone that is using the Infuse 4g in a foreign country has or is experiencing a similar issue, or if anyone can explain why this is happening and if there is a way to fix it.
Im waiting for Infused to come back up to put gingerbread on the phone and hopefully fix this issue.. but I fear it will require more.
To answer my own question I found a solution and testing a second
**Just want to add when I say toggle Softkey, I mean the button to the far left at the bottom**
Solution#1 to get Infuse 4G DATA working on Claro Network Panama:
Goto phone type *#*#197328640#*#*
Goto Debug-->PHONE CONTROL-->NETWORK CONTROL-->BAND SELECTION-->GSM BANDS-->GSM 1900-->Toggle Soft Key-->back-->toggle soft key-->END
This will give you a stable EDGE connection on the Infuse 4G
I will post a possible 3G fix after I have tested the setting for more than a day.
OK so Im pretty confident I got the 3G working now, if you experience this issue of losing Data on the network in other foreign countries to USA/CANADA this might help you out aswell.
**Just want to add when I say toggle Softkey, I mean the button to the far left at the bottom**
So again goto phone dial *#*#197328640#*#*
Goto DEBUG SCREEN-->PHONE CONTROL-->HSPA CAT CONTROL-->HSDPA DISABLE-->Toggle soft key-->Back-->toggle soft key-->END
If you followed my steps to gain access to EDGE you must do this also
DEBUG SCREEN--> PHONE CONTROL --> NETWORK CONTROL -->BAND SELECTION --> AUTOMATIC --> TOGGLE SOFT KEY --> BACK--> TOGGLE SOFT KEY --> END
so that you can access the other bands for 3G
Hope this helps people.
Also Would like to Add that Im using INFUSED v2.0.4 http://forum.xda-developers.com/showthread.php?t=1220088
and I switched to the ROGERS MODEM http://forum.xda-developers.com/showthread.php?t=1173704
With these settings applied.
The other way around this is if you install the Infused ROM it'll give you the option to manually lock to the network. The AT&T ROM has ATT roaming partner preference built in... super annoying, but is what it is. I had issues where putting in a foreign SIM I could only attach to networks AT&T had roaming agreeements with even though it wasn't an ATT sim and the non-ATT stock ROM solved it for me.
I saw network locking also in the debug menu, is that what you are talking about?
I cannot find any network locking within the normal menus.. if there is could you guide me to it please.
well I tried the lock via the debug menu.. and did not work when I enabled HSDPA.. maybe the issue isnt a foreign carrier issue or combination of a foreign carrier or just the fact that its a carrier that offer 4G but only on contract.
I was speaking to a friend last night, and he said when he was in the US he was experiencing a similar problem with ATT and the people at ATT said the phone will experience these issues on networks that have the ability of 4G or the HSDPA+ higher speeds since we know that its not real 4G.. so the phone attempts to connect or do whatever it does to obtain those higher speeds of HSDPA+, but is being refused by the network because you need to be on contract or have it enabled.. which then in turn causes it to disconnect all together from the data network.
So it made sense to disable to the HSDPA in the scenario.. I might add that by doing this on CLARO you do not get the full 3G experience its slower from about 2Mbit down to .50 Mbit but its still better than edge. and the HSUPA works fine with a 2Mbit Upload.
Im going to obtain a contracted SIM today with 4G enabled.. and remove all the steps I listed above to confirm that this is actually case.
I will post my results when I get the chip.

Please help! No 3G or GSM, can't call, but LTE works fine.

I really need help with my device, I searched all over XDA and no-one seems to have the same issue as me.
Here is some information:
1) Nexus 6P (H1511)
2) 6.0.1 Absolute stock, no rom, no root, no custom recovery. Build number MMB29P.
Recently got a new Nexus 6P and imported to Russia. All of the major bands here are supported. And the phone worked excellent for a few weeks, but then it lost all 3G or GSM connectivity. Just randomly,didn't do anything with it, the only thing I did is move to another city but than I got back, the issue didn't resolve. LTE works perfectly but can't call or receive calls, can receive sms though. Reseting network settings and factory reset changed nothing. Tried manualy set network to WCDMA or GSM with *#*#4636#*#* command, the moment I switch to anything besides LTE the connection is lost. Contacted the provider, no problem on their side, my SIM works good in other phones, my phone with other SIMs - no.
I don't think it is a hardware issue because a few times I managed to get everything working after an hour of switching networks and bands with no particular order in the *#*#4636#*#* testing mode.
After a while I figured that if I set phone to "GSM only" on USA bands in testing mode, but at the same time set it to "LTE prefered" in the normal network settings menu. I am able to set phone to Band mode 7 and set the network back to 2G in network settings keeping it on " GSM only" the whole time and only after this compicated algorithm and after a reboot 2G and 3G starts working. But any reboot after that revertes everything back to only LTE stage. Also if I get everything working but than reset network settings everything stops working again.
I have no idea what caused such an issue, I really hope someone can help.
Sorry couldn't post screenshots because of the "10 posts rule".

G920R7 GSM Unlock..... Feel like I'm close....

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.
