[Q] TMobile G2 data connection lost on Polish Orange network - G2 and Desire Z Q&A, Help & Troubleshooting

I have my G2 for over 2 years now. It was originally bought from US Tmo, and I was travelling a lot to Poland. Since I was "good" customer they send me unlock codes when I asked and on my trips I was using Polish Orange pre-paids with data and everything was working fine (actually I was doing same with G1 for well over 2 previous years). I moved to Poland and my phone was still working OK, but at some point data connection was permanently lost (only cell data - WiFi works fine): phone tries to connect at various speeds (icon cycles) but no connection or data transfer is established. Tried that on my old G1 and same thing happens. I went to Orange and they checked my settings, phone, sim card and found nothing - they even replaced my SIM card (for free), but still the same - they got no other suggestions.
So I decided to root my phone (in hope it will solve problem) and installed different rom (CM7). No change - I tried to install different radios - no change.
I noticed that my data connection stopped working around time when TMobile got into Poland. So my question is if it is possible that Orange started blocking something (tmo phones) - if possible what could indicate to orange that my phone is tmo (it is rooted). Maybe there is something else I can try to change/flash or it might be totally different problem - like they started using both frequencies simultaneously and US phones have only 2100 in common?
Would appreciate any help. Of course I can try to switch to tmo or other carrier, but I like my number and a lot of people have it and with prepaid it is almost impossible to switch to other prepaid and not to loose number - and I don't want any contracts.

APN's?
Could it have something to do with the APN's for the data side of the phone? Have you looked into those values (for both Orange and T-mobile) to see which one you have?

You must change APN configuration

[Solved] Your sim card does not allow a connection to this network

Solved for me @ post #5 http://forum.xda-developers.com/showpost.php?p=10865272&postcount=5
I've searched, read, and called my mobile provider (3 UK) to no avail, so I'm starting a fresh thread on this issue.
Relevant details:
Nokia E65 + 3 PAYG sim = ok
HTC Desire unlocked (from T-Mobile) + 3 PAYG sim = "Your sim card does not allow a connection to this network"
HTC Desire above, + O2 + Virgin sim = ok
From what I've learned this has nothing to do with Android os, ROM or RUU etc., and is purely a setting/sim/connection/whatever problem. Or is it?
I bought an unlocked T-mob-branded Desire which works with o2/virgin sims, but selecting my 3 network results in the "Your sim card does not allow a connection to this network" message - yet same sim is fine in my Nokia. Which I cannot work out as that implies it's a combination of phone+network, surely?
When I first got the phone, unpacked it, 3 sim in, it worked, so I rooted w. Unrevoked it and it still worked, then I Nandroid-backup'd (which I still have), then I tried I think Cyan rom 6ish, and Oxygen 2 rc6 with a Goldcard in place [goldcard has nothing to do with sim/connection, just flashing, correct?], no service/not allowed on network; same with oxygen rom. So I nandroided-restored and still no luck.
I unrooted by RUU-ing with:
RUU_Bravo_Froyo_HTC_WWE_2.29.405.5_Radio_32.49.00. 32U_5.11.05.27_release_signed.exe
(I'm on 3 so tried RUU_Bravo_H3G_UK_1.22.771.1_Radio_32.36.00.28U_4.06.00.
02_2_release_127568_signed.exe to get a '3-rom'd phone' but I can't downgrade-which is fine by me)
so I'm back to Froyo 2.2 stock/whatever it's called, and no luck still. I mention this as I'm sure all this rom-ing has absolutely nothing to do with it but would like to be clear.
Has anyone any idea what causes this occur - not connecting that is - would 'disconnecting from network, romming, loading a new rom w/ sim, connecting and getting maybe kicked off' be the case? Or is this certainly a problem with the sim and this phone and the network; or can somehow a phone be unlocked only on certain rom and not transfer (certain this is not correct) to another - unbranding via goldcard + RUU 2.29..... has been done numerous times by people yet I seem to get this problem.
Long post, but if someone can definitely help it would be greatly appreciated - while comments like 'have you rebooted' are nice, yes, I have many many times, wipes settings, factory restored data, input apn settings, *#4636#*#* doesn't show anything I can really find of use (I tried selecting GSM only, WCDAM only, neither work) and I've tried manually/automatically connecting to network but am plagued with my "Your sim card does not allow a connection to this network" message. Which ultimately makes my £300 phone as much use as an iPhone 4 being held wrong.
I cannot understand how my sim worked before on the same phone, but now after tinkering (nothing of which I think can effect this problem) it's not working again. Apart from my old Nokia.
goto *#*#4636#*#* and post your signal strength (in dbm) and LAC and CID values. It will also be good if you could attach output of logcat -b radio.
This is a well known problem with a no known answer.
Is the number stored correctly - i.e. it hasn't lost the '+' from a number starting 44?
Sent from my HTC Desire using XDA App
I had the same problem two weeks ago when I returned from my holidays. I put in my 3 UK sim and it refused to connect with that same error. Sim worked perfectly in other phones.
Finally 3 UK advised me to do a factory reset on my from the Settings->Storage menu which resolved the issue. You seem to have done a full restore from a RUU which probably should be equal to doing a factory reset. But it's probably worth while doing it anyway in case the issue was with the /data or cache partition which for some reason might not have been cleaned by the RUU.
Well, I *think* I've fixed this (for me at least) - just waited a few days and tested to make sure it wasn't a 'ymmv' quick quip fix.
Basically, I'm on 3 - 3G only - and phone was set to 'WCDMA (3G) preferred' - with low signal/reception (-113dbm) it seemingly tries to get the 2G signals around (Orange-whom 3 piggyback[ed] on in low 3G areas; and O2) while changing to 'WCDMA Only' forced it to only try 3G networks - 3.
So, try this:
Key in, but don't 'call': *#*#4636#*#*
Select Phone Information
Near bottom, Set preferred network type to: WCDMA Only
Fixed it for me instantly. Three mobile UK still has -111dbm as it's best reception here but now at least I can connect to it
Let me know if this fixes it for you (clearly, if you're on a 2G-only network selecting GSM only (2G) may work).
checked your IMEI matches from *#06# and the back of the phone?
Yep, IMEIs match. I think it's (been) purely a network choice/connection issue, at least for me.
hi all. I was as usual using my xperia j but 3g signal was low so I installed signal booster app and after boosting signal the app asked with a popup window to enter network unlock password. I without thinking anything entered 12345 and after this it said wrong network password. since this happened I am getting error on Xperia J (st26i) that your sim doesn't allow connection to this network. I tried with many sims but no signal. It always shows all networks when search for network manually. But gives that above mentioned error when trying to connect to any searched network. I checked if my imei is blacklisted but there's no problem about imei. its clean. I flashed stock rom, custom rom but nothing helped. how to solve this strange error.
Mehul (nope imei does not match)

[Q] Why Does my Korean N7100 think I'm roaming and not connect to mobile internet?

I bought my n7100 on taobao here in China, and it's a Korean version. I put my China Mobile sim card in, and it makes and receives calls, and text messages and can use wifi with no problem.
The only thing is the mobile data doesn't work. I rooted and tried tweakker, and HiNet, to reset my APN and MMS settings, but that didn't work. My phone still thinks I'm roaming.. it displays
this message "Data Roaming, You have lost data connectivity because you let your home network with data roaming turned off".
I've also tried updating the APN and MMS settings manualy with information i've found on the web.
I've googled and searched this forum and I can't find much. I thought it would be an easy APN settings fix but it seems not to be...
I took my phone in to the local China Mobile store they couldn't fix it. I took it to a local android expert here and they didn't know what to do.
Any ideas would be greatly appreciated.
If you bought a Korean Note 2, you don't (shouldn't) have an N7100. I also purchased one through Taobao.
You should have an SHV-E250S, E250L, or E250K. Which one do you have? Check the baseband version under Settings > About device page.
No matter what, you're going to be limited to 2G only with China Mobile.
You're right, It's SHV-E250S, and I'm fine using the 2g in China on China mobile, but I'd just like to know how..any help?
Baseband Version is E-250SKSVLJK
Try removing all modifications to your APN settings.
Next, go into Settings > More settings > Mobile networks > Network mode and change it to GSM only. Also make sure that Data roaming is not selected. Run a new scan for network operators while you're in there to refresh your APN settings to the right ones.
In data network mode I only have 2 options "3g only" or "LTE Preferred" I have it on 3g only. I have now unchecked data roaming, but I don't see any place to scan for network operators. I have included a few screenshots here, sorry i don't know how to insert them.. http://tinypic.com/r/2198djn/6 http://tinypic.com/r/24dhfmx/6 http://tinypic.com/r/2zof98w/6
Now it's obvious why you don't have data. Is this the stock Korean ROM? Are you rooted?
I can point you to a decent ROM that will fix all of this, provided you have the patience to fix it. It's relatively easy.
Yes it seems to be the stock Korean ROM. I am rooted using http://forum.xda-developers.com/showpost.php?p=31801060&postcount=2 I'm more than willing to flash another rom. I've put about 20 hours into this so far, I imagine I can muster enough patience to finish it
Once they give us a damn Korean Note II section, this kind of information will be a lot easier to find.
Try this ROM for now, it's the one I've been using for a few weeks and I love it.

Thanks a lot the rom (715mb) is downloading now, I have tried to flash ROM's on my old galaxy nexus, and on this note II, but I never succeeded, can you please link me to a good guide, on how to flash this rom? thanks.
Odin is included in the download. If you're using Windows 7 you may or may not have the drivers for the phone, and can grab them out of the All-in-one Toolkit. Just installing the toolkit should install the drivers necessary.

The ROM you're downloading has two files and two pictures, as well. Open the pictures and follow along. All you have to do is click two buttons, select two files, then hit start. It WILL wipe your phone.
I installed that rom you suggested, I went into settings and did GSM only, and had it automatically find my network (china mobile) selected it, rebooted, and still it says i'm roaming so there is no connectivity... any more ideas?
Can you try somebody else's SIM?
There's no reason you should not be getting service unless something is not right with your SIM or phone.
I installed the rom you suggested, i went into settings and made it GSM only, also had it automatically correctly locate my network (china mobile) and it said "registered on network".. but it still isn't working, same problem, it says no connectivity cus i'm roaming.. any ideas now?
my gf will be home from work in a couple hours, I can try her sim card then.. my sim card was cut by me for my old iPhone.. is it possible or likely that the phone can still make and receive calls, but that somehow data connectivity was affected by me cutting the card? also one guy at the phone fixing store tried his sim card (from another company) and internet worked fine he said..

China mobile have various sim plans, from local to province to national. Are you using the sim in the same city in which you bought it? If not and you don't have a national plan, it could be why the phone is showing roaming. In China going from one province to another is already considered roaming unless you have a national plan. This is from my experience back 2 years ago. Also, you best check at a China mobile shop if you have data activated, gprs/edge is not activated by default, you need to ask them to do it.
I would advise you to switch to China unicom as they have 3g/hspa which is much faster than china mobile.
Sent from my GT-N7105 using xda premium
For clarfication, I am in Hainan, and the card is from hainan. I use the same sim card in my galaxy nexus without any problem. I tried my gf's card just now, it didn't say any problem with connectivity, and did not display roaming.. And it shows the G symbol (for 2 or 3 G I assume), and has up and down arrows next to it.. but it doesn't actually work for browsing the web or using apps over the data network.. I even reset all the APN settings and let it automatically find the China Mobile network, but it didn't help.. what if I try to set the APN settings manualy? and any other ideas??
Showing the G symbol is GPRS, which is 2G. You will not get 3G on the N7100, N7105, or Korean model Note 2 on China Mobile.
Sounds like you need a new SIM card. You can try to set the APN manually to make the data work with hers. I've never had to set an APN manually and I've used many phones here with all 3 carriers, so it's a bit odd to me. No clue why your card doesn't work, but since hers is working fine, it's definitely not your phone.
For the record, her card displayed G, but even after messing with settings, I couldn't get it to have working data network..
Today I bought a new card, and had it officially cut to size, put it in the note II and it's still telling me no data connectivity due to i'm roaming.. i'm so frustrated
edit: after restarting a few times and trying to automatically make it register on china mobile .. it worked on the 4th attempt.. it still displays data roaming, and I had to enable data roaming... but now it works, even though it says i'm roaming?? wtf
Ive the same problem with my Korean galaxy note 2 all voice service work perfect but when I tried to turn on data it says insert Usim Card to access network please help

DINC2 unlocked but doesn't recognize SIM in Panama...help!!!

hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.

[Q] How to fix baseband/radio to include new operator [WAS issue after sim switch]

Hey there,
TL;DR : phone stuck on roaming network, unable to find other networks when scanning.
I've been reading alot around here for a while since a few months, and I'm now asking for help about an issue that I don't know how to fix it.
I'm using a S-ON One V in France (primoU).
I've changed my network operator last week. There are 4 real operators in France (Orange - 208-01, Free - 208-15, Bouygues 208-20 and SFR - 208-10). I've moved from a virtual operator (Prixtel - SFR network) to Free. Free has launched its network last year and has contracted a roaming agreement with Orange to use its network.
My issue is that my phone is stuck on Orange network and is unable to "view" the others and therefore unable to register on Free network. I'm pretty sure that it's a software issue because : i) I was able to scan and see all networks with this ROM, prior changing the sim card, ii) I have a Windows phone right under the hand with the same operator and it's able to scan and view the 4 networks and iii) checking the MCC and the MNC gives the code 208-01. I've performed a crossed check, too, and my HOV still shows the issue with the other sim card, while the Lumia is able to view 3 networks (all but Free) with mine.
It wouldn't be much a big deal since Orange has an excellent quality network if Free wasn't restricting data access on roaming (to cut the costly usage fee, seemingly).
When facing this problem, I was using Omega 2.5.0 with IronMan kernel for a whole month.
As Omega has became extremely laggy and unstable in less than 3 weeks, I thought I would kill two birds with one stone by changing to a new ROM. So I moved to C-Bean with Hellboy-CM10 kernel.
And still the same issue. As with CM10, CyanSense and Shpongle.
So I flashed back to stock ROM with stock kernel (and keeping TWRP recovery). Still the issue.
I then found this thread wich is somewhat related, since the "error while scanning for network" occured sometimes with Shpongle-based (and so AOSP-based) ROMs.
But I wonder why I still face this problem with the stock ROM and why the "error while scanning for network" still poped up when I tested CM-based ROMs (CM10 and CyanSense), while my phone was still S-ON (which shoud prevent radio flashing, as far as I know).
So I went through the Sensation thread about fixing the radio and RIL and I jumped to the conclusion that I may be looking in the wrong way, since I should have fixed the problem when flashing the stock ROM.
Now I've S-OFF the phone and gathered some infos.
Radio (gsm.vers.baseband) : 20.79a.30.0835U_3831.24.01.30_M
RIL (gsm.version.ril-impl) : HTC-RIL 2.2.0039HM (strangely enough, GetRIL shows "unknown")
CID : 61915329
I don't know what to do know now. I'm afraid to mess up the whole thing with somewhat random flashs.
What should I do to fix it?
Thanks for reading.
I've flashed the RUU and the phone keeps recognising the roaming network only.
How can I fix it if the problem is still there with a 100% stock software/firmware ?
OK so I put my former sim card in and performed a network search. I found all the networks available. I changed absolutely nothing else.
Could it possibly be an hardware malfunction between the phone and the sim cards from the provider (since I've been able to reproduce the issue with other sim cards from the same provider) ?
Okay, last bump before I give up.
A crossed check was performed by technicians operator in shop. They recorded the impossibility for my HOV to scan and view the Free network and sent me back to HTC.
I took some time to explain the problem to the HTC call-center guy. And he bounced me back because they don't care since the phone is working even if it's in roaming 100% of time.
As it has been suggested to me by an IT guy, it could be the baseband/radio firmware that may not be up-to-date, as the Free operator has entered the marketplace in early 2013.
Do you know if it's possible and if there a way to fix the radio? :/
EDIT : I managed to borrow a HTC Wildfire Buzz, and it shows exactly the same issue as my One V...

A505U can't access Visible network

I've tried everything, so hopefully someone can shine some light into this issue.
I bought a new (unused but from a 3rd party) Samsung Galaxy A50 (A505U) Verizon branded and unlocked. Got a sim card from Visible and went to get it connected. Nothing. WiFi works, everything works, but no cell service.
Here's what I've done (some multiple times)
- reset everything to include network settings, hard reset, etc
- removing the sim, resetting, putting the sim back in. I always get a notification saying the sim card is removed and it goes away when I put the sim back in, so it is recognizing a sim card is in there
- switched sims with another Visible phone/sim and nothing. Both sims worked on other phone but neither worked on this phone
- tried getting into the hidden menus but none of them worked
- talked to Visible tech support which upgraded the issue to the highest level and concluded it's the phone
- Visible believes it's the APN settings but I cannot edit current APNs nor add new ones (grayed out)
- manually add networks, I can see Visible, TMobile, ATT, and some weird numbers, but when I try to connect to Visible it says cannot register on the network, other networks say the sim is not setup for them
- sometimes I get the icon that shows all bars but they're grayed out, sometimes it shows 3-4 bars lit up, sometimes even shows a 4G icon, but mostly the grayed out bars
- sent the phone to Samsung, they tested it and found no faults, guess the hardware is good, ruled that out.
- got into dev options but I'm aware the OEM unlock is not on option on the A505U, not sure if I can change anything else.
I'm out of options. Any other ideas? I think if I can either get into the hidden menus I'll be able to diagnose it better, or if I can somehow change the APN settings I'll be able to set it up. Visible tech support thinks it's the APN, which makes sense to me, but I can't change them.
Any help is greatly appreciated.
I was able to get into the CSC change function, there's not many there, but would changing the CSC help? If so, which should I go to?
I've had a similar issue. Was working fine until the Android 10 update arrived. Since then, it won't work with my total wireless sim card. Tried 3 different sim cards on it, but nothing. Can't add it do anything with the APN, and getting into the phone info hidden menu doesn't help any. I suspect it's a bug in the new firmware or something like that. Works fine with a Verizon SIM though.
Update: Verizon SIM no longer connects to phone. Still works with LTE data. It seems that the CDMA radio quit working with the update to Android 10. Must have been collecting to the Verizon network with VoLTE until it updated the provisioning or something.
So, I finally figured out a workaround for mine that was able to get both data and voice networks to connect while using total wireless, which is an MVNO on the Verizon network. I pretty much narrowed it down to being an issue with the modem not working with CDMA. What I did was download the last Android 9 firmware and flashed just the modem (file starts with CP_) using Odin. After that, I rebooted it and voila! It connected.
Just thought i would give my experience as i just delt with this. i got my 10 update this morning nd let it update and apon a reboot i lost all mobile connection, a signal bar would show for a few seconds looking like it was trying to lock in a signal and it would go back to the ⌀ symbol. i tried flashing the android 9 modem from 2 different updates and neither fixed it. i just decided to order a new phone as i feel its time anyways. my next attempt will be to flash android 9 back using odin then just throw this phone up on craigslist
edit: odin successfully flashed back to android 9 and signal now works again. so if anyone has this issue you can try the method above of just flashing the modem and if that doesnt work you can go back to 9 and restore functionality of verizon mvno's

samsung a50 not connecting to VZW towers (red pocket)
My phone is doing the exact same thing and while I can appreciate how you resolved the issue it doesn't make much sense to me.
I use Red Pocket for my network. (Which uses Verizon towers - I use the CDMA Sim)
Before this major update to 10 my phone worked flawlessly. Now it won't connect to the network much like you guys have stated in this thread. Mine will connect intermittently for like 3 or 4 min tops and then get kicked off the tower and will actually not show any bars (Circle with a line through it) to show no service for about 10 or so minutes then restart the whole process.
I also have a work phone (2nd phone) that is directly tied to the verizon towers on the verizon network. If I take the sim out of that phone and put it in my samsung a50 the samsung a50 is happy and can make phone calls, send texts, and stays on the vzw towers with no disconnects.
If I take my red pocket sim card and place it in my work phone that phone also works just fine - send messages, make phone calls, and stays on the vzw towers with no disconnects. (work phone = iphoneXR - it's free, sue me)
Even though reverting the modem obviously fixes your issue I do not think that is the actual problem. It also doesn't seem that a third party carrier is being randomly booted off the towers, it seems to be a glitch with third party carriers using third party sims utilizing this new android 10 software that VZW towers do not like.
Which obviously points to an issue with Samsung's latest software not being compatible with third party carriers.
I can't seem to contact Samsung in a direct manner to resolve this issue as they want me to take it to a third party store to have it looked at. I spent 2 and half hours with tech support from red pocket and they came to the conclusion that VZW was doing "upgrades/maintenance" to their towers in my area. (whatever that means.
Any ideas on how I can contact Samsung directly to detail this issue to them? I really do not want to have to root my phone in order to use odin to set my modem back to version 9 as I'm hearing that doing so voids all kinds of implied warranties with the phone and it's only 6 months old.
Appreciate any help that you guys might be able to steer me towards.
Thanks.
Before this major update to 10 my phone worked flawlessly- They Told you the answer, Odin # 9 or if its under warranty take it back Good luck.
My phone (SM-A505U) wasn't even working on visible before android 10.
See my post at the end of this thread: https://forum.xda-developers.com/ga...official-firmware-t3955727/page2#post83845605
I have that problem too. Where I can download v9. I got the Odin.
