I have a different thread in this forum where I was asking slightly different questions... I found some new info and the old title isnt as appropriate anymore so heres the new stuff...
The situation is this. I have a I727R which is the Rogers Galaxy S2 LTE. I am trying to get it on a different network (same frequencies, etc... in fact same towers in many cases). The network I am trying to get onto is MTS.
Previously it seemed the phone was not capable of getting any type of signal as I would never ever see any carriers when I searched for available networks under the "Network Operators" section. However since getting back to the city I can now see one carrier listed as "302660" which according to this site: http://rebelsimcard.com/listed-adde...and-mobile-country-code-mcc.html#.UBbxurSe6So is the mobile network/country code of MTS. Even with my MTS SIM in the phone it wont use this network and on other phones the network actually shows up as MTS and not 302660.
It seems that there is something that I need to do with the Radio to get it working. Not sure if this one is locked in some fashion or what. Has anyone experienced this? Any suggestions?

did you try *#2263# or still nothing happens when u enter the service code, my thinking is u have to force it to use a frequency that mts is on even though its the same as rogers, and you are sure its unlocked
edit: almost positive thats the problem, i was mucking around w/that menu and picked something accidently and i lost my connection
Yeah that menu works if I flash to stock with either GB or ICS but doesnt work in CM9
I have tried all of them. This phone is just stubborn. In another development I actually used ODIN to go back to Stock GB and the phone was just screwed up. So now I'm trying to wipe it completely clean (Wipe Data/Factory Reset x 5, Format System x 5, Format basically anything I could x 5 , Wipe Cache, Wipe Dalvik, etc.) then flash to one of the stock images.
I'm also redownloading them both and going to compare the MD5's on them to see if they match or if I had a bad download.
I'm not sure if there is another way to completely wipe the phone clean (as in I dont care/want any data on it...). I see the repartition option but see many warnings about using it
Compared MD5's and they matched on both downloads (different PC, different internet connection) but this time the flash back to stock GB worked (no FCs). However the network still shows up as 302660 instead of "MTS". Using *#2263# I tried leaving it on Automatic, setting it to WCDMA 850 (my GNex is set to WCDMA Preferred), GSM 850, WCDMA ALL and GSM ALL but it always shows up the same and wont let me join (under GSM it doesnt show up at all actually). I didnt touch the LTE menu item because nobody around here has rolled out their LTE network yet
The oddness of these issues actually makes me suspect there are bad "sectors" on the internal memory or something... is there anything to check it?
EDIT: Just another update... using my AT&T SIM in my GNex I can put it on WCDMA Preferred and then search network operators. I get 3 different networks to come up (302220 302610 and CAN Rogers Wireless). If I click on CAN Rogers Wireless the phone gets signal and registers on the network.
If I do the same in the S2 LTE I only see the 302660 network still and cant register on it. The others dont show up at all (not even the Rogers one which is odd to say the least)
Its looking like there is some wierd hardware issue on this phone that I just cant figure out
the only way to solve this is to do further testing
try skyics 4.2f6, he has all the radios there, try each one and see what happens, when switching different radios flash them twice, the service code 2263 works with this rom
SKY-ICS 4.2F6-2.4
Ok I've typed this post like 8 times and it keeps telling me my post cant be submitted... arrgghhh... here goes again (losing detail as I continue to try)
I've tried your suggestion above with basically the same results. I have made a few more obervations though...
- My MTS SIM doesnt always read and it seems ROM dependent. There are times when I've had it reading the SIM without issue on a ROM then i flash to another ROM and it wont read no matter what I do. However the AT&T SIM reads on every single ROM (still no signal). If i have the patience to continue playing with this phone I might try and narrow down which ROMs will read the card and which wont (then reflash and see if thats still the case)
- With SkyICS when I dont have any SIM inserted (which is the same as having my MTS SIM inserted since it never sees it ) the phone shows signal! Oddly enough it shows this signal on the LTE band of which no providers in my area have an LTE network (tested by setting the bands using *#2263#). MTS is supposedly getting one later this year/early next year so maybe I'm seeing some sort of test network?
- It almost seems to me like its not actually unlocked (even though we purchased the SIM Unlock code from cellunlocker.net). Not sure how to test it or how to try putting it in again seeing as it never pops up and asks since we unlocked it. How does it know its unlocked once its been done? I mean if I go back to stock through ODIN should it be locked again? My brother replaced 2 pieces of hardware after unlocking it (the SIM reader and the USB port) so not sure if that would have anything to do with it.
At this point I'm almost writing it off as busted. My friend on Rogers is away but thats the last thing I'd like to try is using a Rogers SIM
The only way to tell if its unlocked is in stock with a sim from another carrier, so if its a rogers phone dont use a rogers sim, when the phone boots it will ask u for the unlock code if its locked, if its unlocked it will just boot into android. Once its unlocked it stays unlocked forever, unless you change the memory chip, wherever that chip is i dont know
Posted w/xda app w/ i727R
MY STICKIES
| ROMS | KERNELS | FIRMWARE | RADIOS | HOWTO'S | GUIDES | INFo |
NEWB GUIDES TO: RESTORE TO STOCK | USE ODIN | INSTALL CWM | ROOT |
Yeah its unlocked then I guess. I only have non-Rogers SIM cards and its never prompted me since. Think I'll just trash it... maybe I can convince my brother to get a GNex since I know they work
Thanks so much for all the suggestions. Your patience and investment in this is very much appreciated!

im using rogers ics radio xlf3, seems all radios work with rogers or att.
i got some news for u, my problem was when i was in toronto i wasnt getting lte, i went to mobile settings and seen it was set to gsm/hspa, so i picked gsm/hspa/lte/ , but would not stick.
so i went into 2263 menu and picked lte, then "all" then left haptic button and hit "end", then i got lte.
when i got home there is no lte so i wasnt getting a signal, data or voice, and i could not pick an operator as none would be visible, nada.
so i did the 2263 menu and chose automatic then hit left haptic button and choosed "end", then bam got connected to rogers.
for mts its either gsm or wdcma in the 850mhz range, or pick all, you will have to test or try this procedure.
or try this is from seans old skyics instructions to get data working so it should work for voice but i edited for your needs, try w/out sim or with sim to see what happens, mine worked w/sim installed:
power off phone and remove sim card
then reboot phone (no sim card)
and when up go to phone and dial *#2263#
Select ? Settings(for u pick what mts has, maybe auto or wdcma and pick 850Mhz or all bands, this is where you will have to test)
then bottom left haptic button hit end
Open dialer again.
Dial *#2263#
select automatic
Right bottom feedback button/end
power down
now place sim back in phone
reboot
im almost sure your problem lies in the band frequency for mts, you just have to set it properly
edit: when you get into the 2263 menu see which item has an asterik next to it, thats the one currently set to
edit: it seems like the second item, wcdma, is the hspa band, which is mts's band, or try automatic
My husband finally let me root and rom his S3 (I have a Gnex). Unlocking the bootloader and rooting (using Odin) went well. When I installed SlimBean+GApps, however, we started having an issue. He kept losing 3 & 4G signal. We didn't know about the roaming issue, so I had not backed up the IMEI. I flashed Clean Rom, and the issue is partially fixed.
The phone's signal is fine now, 3-4 bars 4G most of the time. The trouble is, we can't dial out to any numbers, and any calls to the phone go straight to voicemail. We've pulled the sim card and let it sit for a bit, but that didn't help. Dialing *228 (as Verizon tech support had him do about 4,583 times) just brings up a message about the phone being activated by the sim card, and roaming capabilities being updated. All tech support had to say was that Google Voice was probably the problem, even though we've both had it for ages with zero issues. :/
Any ideas? I don't really want to unroot and take it in to the Verizon store, but I will if there is no alternative.
EDIT: Just discovered that 4G is only working when "Preferred network mode" is set to Global, rather than LTE/CDMA.
*228 is for 3g phones only, it does absolutely nothing for LTE sim phones. Here's your solution btw.
I knew it! I kept telling them I didn't think that was supposed to do anything when I have a sim card. Crazy first string tech support. They also didn't know my battery was removable.
Will try the things listed in that link, thanks.

Haha Verizon lost credibility with me when I rented their global phone for travel last summer and when I got back to the US the instructions to get my GSIII working began with dialing *228. There wasn't even a warning about it being unnecessary for LTE sim phones.
Good luck and let me know how that goes.
First allow me to say that I wish my first post was not a question, but a helpful comment to someone who needs it...yet trouble has found me and I can't seem to figure this out on my own and really need someone who has the skills and experience.
I know the phone is OLD and should be retired as it is nearing the EOL of its' technology, but I just can't afford to spend the money on a new one right now.
History of the phone is:
Bought new in late 2011, carrier Metro PCS, rooted on the second day of ownership.
Rom'd on the third day with GSE, used that for a while then went over to Black Plague.
Used phone this way for the entire time.
Always kept drivers installed on my Windows PC, 7x64.
A little over a week ago I had some driver issue which caused me to re-download the drivers. After I re-installed them I connected the phone and ran the LGMST. It brought me from the ZVD to ZVE without incident.
Phone has not had data service since.
I phoned Metro PCS distributor help line at 800 901 6266 and spoke to someone who tried to help a bit. They did an OTA push then had me try to re-provision the phone with the *228, no go...
I checked through the web for help, reading many posts about APNs, using Any Cut, located my access pin for the service menu. (didn't make any changes for fear of making things worse)
Then I brought the rooted phone into a Metro store I frequent and asked one of the associates who does this stuff on the side to help me out. He spent about fifteen minutes with the phone and told me he couldn't figure out why it wasn't working.
When I got home, I emailed PG about the issue hoping he could offer some advice. He told me to try TOT downgrading. He provided a few links and I set out to DG with TOT.
The LGNPST didn't install. (received error code 2203) tried a couple other downloads of the LGNPST but all fail with the same error. (I am admin, took ownership of files, edited security of folders as described in some forums from Microsoft about the error code and even tried letting windows install with compatibility settings, but darn thing just won't install)
I then figured I'd try un-rooting and a factory reset. t un-rooted fine and reset to stock, but still not an iota of data 4g,3g, or 1g to be found. (everything else works fine)
I then re-rooted the phone and tried L-Drifta's rom for ZVD Number Two.
It installed fine and works good, except for YouTube force closing all the time, but still no data service.
Does anyone have any idea what happened to this phone? If not, then how about someone helping out with how to manually program the radio part of the phone for service.
Thanks to everyone
CDMA Only selected
Update - - -
So I mustered up the nerve to mess with the network settings in the Metro hidden menu and changed it from CDMA & LTE Hybrid mode to CDMA only and have 3G back, but when I change it to LTE or keep it in Hybrid Mode I loose all data service.
I know I shouldn't keep playing around with the settings, but I just can't leave it alone now that I made some progress. It's like a gnat that I gotta keep swatting until it is gone for good.
Anyone have suggestions for getting my 4G service back?
LG MS910 losing 4G and switching to 3G then no data at all!
Device: LG MS910
Carrier: MetroPCS
Issue: No data
I have a cardinal rule with my phone: "Never use WiFi". WiFi networks are bay nature unsecure. I went to Starbucks and decided to connect to WiFi since I only had 1 bar. The area had poor network coverage.
Now my phone starts in 4G, goes to 3G, then no data after that. 5 minutes later the 3G returns. Data speeds are ZERO!
I've been with Metro long enough to know 1xRTT is faster than ZERO data. Did I get an sms trojan? Is MetroPCS messing with the network with no notification to customers?
For data, the LG MS910 has CDMA (1XRTT, EDVO) and LTE (4GLTE) radios. Why is the 3G icon appearing? The LG MS910 on MetroPCS technically isn't capable of T-Mobile's HSPA+ which uses a GSM signal. Regardless if T-Mobile and MetroPCS have merged, T-Mobile is a GSM carrier and therefore MetroPCS customers wouldn't benefit from T-Mobile's HSPA+ network anyway.
Bottom line: Something isn't right. Any ideas?

Question about Selectel Flash. Selectel Sims etc. I apologize up front if this is the wrong section for this thread. I posted as a reply in the General Section Thread about MVNO's but I believe that thread is dead or closed. If this breaks any rules of XDA please let me know and delete this thread. If is is forbidden I apologize up front. And I know this is a TLDR post, but please if you know anything about these matters, please read this post if you might be able to help. And if you just need some info about someone's experience trying to get cheap android phone service keep reading. Maybe you'll learn something from me.
I let a local selectel "dealer" flash my phone to Selectel a while back in Jan sometime. About a month or so later he had to re-flash the phone. Because I couldn't make calls at all. He said this was because the guy working for him did the flash incorrectly and so he fixed it. After reading up on Flashing a bit but still not knowing enough about it, I decided to start using a partition backup tool from the store to backup a slew of partitions including EFS, and all the Modem* partitions. I backed up a bunch of others as well, just not data, system, or cache. He left the VZW sim in.
Now since then, I've flashed a number of roms. And sometimes I'd have an issue where my number and other info in status would be gone. At this point I restore EFS, usually just this one partition and everything would be back to normal. Selectel Number and everything else would work. Now I'm having this issue again but my info is in there. This time, I can't make or receive calls or texts in my home "roaming on a regional tower" area. This always worked fine before. Now at home it says Voice out of service / Data in service. This is at home. When I drive 20 minutes up the road to some different but still not verizon towers I believe, I can make and receive calls just fine. Also in the guys shop using his extender, I can make and receive calls fine. He gave me a T-mobile sim, for what I don't know, but this didn't fix anything. Now he's expecting to receive his selectel SIMS and says that might fix my issue. If not I'll have to do another flash. I can't afford to pay for another flash, being laid off work and unemployed I can barely afford the 15 dollar plan for selectel.
Anyway, I'm wondering if anyone else has came across this issue, and if so do I need to reflash? Is there a way I can fix it myself? I have downloaded a bunch of tools for windows mostly (I use linux mainly, but dual boot into windows for AutoCAD and other things that just don't work well in Linux). I've seen a ton of flashing tools online as well many of which seem to do the job automagically almost. Any suggestions? I was thinking PRL.. Of course, but after reading the first few posts of this thread, i saw the don't try to OTA program information. One guy at the store actually recommended doing that but I didn't. he said *22891 to update roaming which I think is the PRL.
Any Help will be appreciated as always. If anyone here can fix it remotely cheap, let me know. Also, he's blaming my Kitkat rom. I've used this KitKat and others in the past with no Issue at all. But for ****s and giggles, I restored a TW 4.3, the latest Alliance Rom, to no avail. it does the exact same thing. I can use the phone in town or near an extender but not anywhere that I might roam.
Thanks a bunch.

Update since my original post:
I've talked to both selectel and the local selectel dealer, the dealer said his selectel sims are in but won't be ready for a few more days. I'm guessing but don't know for sure, that this could fix my isssues. I doubt it.
I restored a nandroid of a stock based rom (alliance), to try to update the PRL over the air a while back while I was in an area where I knew there would be Verizon towers. It wouldn't update because I didn't have a sim inserted. The dealer took my Verizon SIM and gave me a t-mo sim which didn't help anything at all. I stopped by there Sat 05-23-15 and he gave me a verizon sim to see if it would update using his network extender. I do know he does activation over the extender because I've been there when he's done this. He activated a dumb phone in this manner. I'm very frustrated at this because I need a permanent number to use for job contacts and my home based business doing freelance IT work. I'm not 100& sure the PRL is the issue but it seems that way because I can make calls and receive texts as soon as I get near a VZW tower or extender. At home however where there's only a regional carrier called Appalachian Wireless, it just roams, and says Voice out of service / Data in Service. And as soon as I get away from a Verizon Tower the phone will say this in About Phone / Status.
All my original data should be there because everything show's up correctly in About Phone, My IMEI, MEID, MIN, and Number are correct. He did have to flash the phone to get it to have 3g, so the MEID that shows up isn't for an S3. My IMEI is the one that came with the phone. I asked him and selectel about the legality of flashing the phone and having a donar MEID number or whatever and both said that's fine. They acted like it was completely legal, I'm not so sure. But again, both Selectel and the Dealer told me it was Okay to do that.
I've found some software on here that I can use to update my PRL with a downloaded one but I didn't know what SPC to put in for Selectel I know that with VZW it's all zeros's. Selectel customer service couldn't tell me this and told me to ask the dealer, I did and he said I could use all zero's as well.
I'm wondering if anyone has any suggestions at all, and if you think that once I get a Selectel SIM if it will work. The local dealer told me after I asked, that it would contain all my information, like those numbers I mentioned before and that it could fix it, but of course he says I've messed it up by flashing my phone. The thing is. I have lost all my info after flashing a rom in the past. However, I use a partition tool to backup EFS and other partitions and when I restore the EFS, (from when it was working and roaming), everything worked fine. Also, I know that I've used the rom he questioned in the past with success. I've tried Nameless, Slimroms, Liquid, and a few Lollipop roms with success as long as I restore the aforementioned data when necessary. Doing nvrestore (I had already done nvbackup long ago), doesn't help,. in fact it wipes everything out and I have to manually restore the EFS partition.
I understand that the PRL isn't the answer to everything but it's the only thing I can think of that would affect roaming. I have read that you shouldn't do any kind of OTA activation using *22890 *228 and so on but that I can use *22891 according to both Selectel and the dealer. The dealer wants to reflash the phone for 35 dollars which I can't afford at the moment. I can barely scrape up the 15 dollars for the cheap selectel plan.
On antoher note: I tried using an X2 with tracfone which worked great but wouldn't roam either. Kinda like what i'm experiencing right now. After calling Tracfone, I was told that none of the BYOP Android phones would roam. And one of their reps said their android phones like the Moto E wouldn't roam on non vzw towers either, because before I had my sgs3 flashed to seletel, I was going to get a Moto E Tracfone from Ebay with 2000 minutes and a year of service for 89.99 when they first came out. I didn't want to spend the money on it if it wouldn't roam. Does anyone know if this is in fact true, I can't see tracfone selling android's that won't roam. But I suppose they do. I was then told when I got a partial refund from Tracfone that only their Dumb phones would roam on non-vzw towers but again, this doesn't make good business sense nor does it make asnse at all. I've found a decent Net10 android at a dollar store (Moto E) I believe, for 79 on sale, but again, if it won't roam then it's worthless to me. Any Experience with this? I've searched and searched the internet for information on this subject to no avail. Especially the "Voice out of Service / Data in Service" message in Status.
Again, if I'm not in the correct section please let me know. Finally, I'm very sorry I'm so long winded. but those that know me know I'm long winded in every post I put up here. Sorry about that. I know I know TLDR, but I hope someone reads this and knows a thing or two about this.
Thanks once more.

I seem unable to get LTE on my D850 since I installed CM12.1 and was wondering if this is common for this ROM. I installed the nightly, so I assume its obviously going to be a bit buggy, but to not have LTE working seems strange.
I checked my APN and I tried both ATT LTE and ATT Phone. The ATT LTE gives me a status bar with an exclamation point and never establishes a data connection and ATT Phone gives me HSPA connectivity. At one time, I waited a few hours and it eventually established LTE but that was an uncommon occurrence and its never been repeated since.
With other ROMs I have not seen this issue replicated. I tested on Cyanide L, Euphoria, and the Stock LG ROM and everything worked fine. Any suggestions?
Hey there,
I'm running CyanideL myself, love this ROM.
Which nightly version are you using?
Have you checked that Mobile Networks --> Preferred network type.... is set to LTE?
Have you tried toggling to 3G, getting a connection, then moving back to LTE?
I also have this problem. Has a solution been found?
I just ditched the stock ROM and installed CM12.1 a few days ago. Now LTE has disappeared. I had it, now can't get it. I'm not able to select LTE in the settings→Mobile networks→Preferred network type menu, nor can I select any option that includes LTE in the test menu (*#*#4636#*#*). It's probably some stupid user error, but whatever it is has been eluding me for a day of messing with it.
Presently running cm-12.1-20150804-NIGHTLY-d850.

Interesting...
Have you tried restoring your stock ROM and seeing if it will connect? How about a SIM card pull?

Thanks for the reply. I have not tried returning to the stock ROM. I just got all my apps reinstalled and data restored, widgets installed, screens set up, etc., so I'm not too keen on doing all that again so soon.
I have tried a chicken SIM card pull. I was somewhat fearful of doing a pull "hot" as is usually suggested. I powered down, removed the SIM card, and restarted. After restart, I was able to select LTE in the settings→Mobile networks→Preferred network type menu, and the test menu confirmed that LTE/GSM auto was the preferred network type.
I then powered down, re-installed the SIM, and restarted. After restart the preferred network type had been reset to 3G and I was (am) unable to select LTE.
My conclusion is that this is something to do with the Net10 SIM I'm using. I've ordered a new SIM from Net10. The Net10 rep says a new SIM may fix things. One is on it's way and should be here in a few days. I'll post the result.
[SOLVED]
My new "LTE capable" Net10 SIM arrived today. I had Net10 customer service transfer my service to the new SIM. Now I have LTE; I'm able to select LTE in the Settings→Mobile_Networks→Preferred_Network_Type menu, LTE appears in the CM12.1 status bar, and I'm able to make a solid LTE connection.
I will here piece together everything I've learned from my own experience, Net10 customer support, and internet searching. My conclusion is that there are TWO compounding problems for Tracfone/Net10/StraightTalk users. One is techhnical and the other is marketing.
The technical issue is that all Net10 (also Tracfone and Straight Talk) AT&T SIMs sold up to a couple of months ago don't work with LTE on the AT&T network. That's most of the AT&T SIMs from these companies out there in the world today. This is not widely known – in fact, most of the Net10/TF/ST customer service reps are not aware of it. It's not something that Tracfone and its subsidiaries want known because it would cost them a bundle replacing SIM cards for unhappy customers. If you have a Net10/TF/ST SIM that's more than a few months old, you have to call Net10/TF/ST and buy another new one that's compatible with AT&T LTE if you want LTE service.
So, why don't more Net10/TF/ST AT&T users raise a fuss and demand LTE capable SIMs? That brings us to the marketing issue.
AT&T lies. So do Tracfone and its subsidiaries. AT&T markets its HSPA+ 3G service as 4G when it's not. In fact, the AT&T stock ROMs that most people are using lie. The stock ROMs display 4G or sometimes 4GLTE (depending on ROM version) in the status bar when in fact it's a HSPA+ connection; not 4G let alone LTE. So users cruise along using their old SIM cards happily thinking they have 4G or LTE connections when in fact they do not; and they're none the wiser. It's only more sophisticated users who flash a 3rd party ROM, one that doesn't lie, who figure it out.
