Network issue during roaming - Motorola Atrix 2

Hi,
I am facing network connectivity issue since the time I entered roaming area on my Matrix 2. It does not connect to network. It keeps showing no network, then for 2 seconds it shows emergency call symbol , then for 2 seconds it gets connected to network and again it keeps showing no network. This cycle keeps on repeating.
I searched for the issue and found that it is issue with atrix 2 software and the suggested solution was to install app called network and choose gsm only from it.
I tried it but it doesn't works for me.
I am able to make a call if I dial number exactly at the moment network appears for 2 seconds.
The only temporary solution I was able to find was to dial self number as soon as network appears and then keep on dialing it for around 8-10 times. Then it gets connected to network for 1/2-1 hour and then again it gets disconnected.
Please let me know if anyone has any solution for it.
I am on JB unrooted and using 2g network.

1) Try another SIM ....
2) try flashing ICS radio.img ...... (you shud know some fastboot commands) search the forum
3) try factory reset or reflash JB ..... it might work sometime
if you are using BSNL ..... then i have my sympathies with you :silly: lol

First off wrong forum, should go here http://forum.xda-developers.com/forumdisplay.php?f=1771
Go back to Stock ICS via RSD Lite 6, try SIM with other phone first and check, do not install apps for network improvement as mostly they just turn radio on & off, in worse case they can botch up some internal default settings. Use this for getting a view on network heat range & in particular tower direction to move towards for better reception https://play.google.com/store/apps/details?id=com.staircase3.opensignal&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5zdGFpcmNhc2UzLm9wZW5zaWduYWwiXQ..

Thanks for the reply...
I have already tried that, its not a network or sim card issue. I have tried inserting sim to other phone and it just works fine.
I put it in general section coz when I googled it I came to know that its an issue with every atrix-2 so every one might have faced this issue while roaming.
Also going back to stock have not worked for anyone. Its an issue with atrix-2 software itself.

You seem to have reached to your own final conclusions but yet please understand on JB 4.1.2 leak there has been no one who has echoed your issue (gps is definitely an issue & for some wifi on some particular bands). Also read this http://forum.xda-developers.com/showthread.php?t=1425560
Try flashing the new 4.2.1 ROM based on official leak of 4.1.2 JB as I believe radio is better on it. On JB leak though one thing I can confirm is when phone enters roaming it automatically shuts data randomly and not always & user has to re-enable it. If all fails, fxz to stock ICS and if under warranty claim your stake.

Thanks...will try when I get back to home.
Although I have not reached to conclusion on my own, I search regarding this in Motorola forums and people facing this issue stated that they tried aall the specified methods. They were getting this issue on all os versions.

Please point me towards a link which illustrates issue same as your on JB 4.1.2 specifically.

Verizon Users Getting Stuck in 1X --- PLEASE READ!
For those of you who have the plaguing problem of your data connection dropping to 1X, I'm trying to spearhead this issue with Verizon and need your help.
Everytime I open a ticket, it get's closed stating that it's a signal issue with a specific location. We all know that this is not the case. I finally have got ahold of a Tech supervisor who gave me all of his contact information so that we could ALL direct our issue to him. He would then get it elevated through the proper channels and then hopfully they can find a fix. It's my hope that we can all email or call him and explain our issue. He was very nice to work with on the phone and said he is dedicated to getting the problem resolved. I think he's looking at this from a global look rather than an isolated one like every other tech I've spoken to.
Here is his contact information:

Please email or call him with your information and make sure to inform him all of the steps that you've tried that have been unsuccessful (new phone, hard reset, etc etc).
I will try and follow up with him later in the week. Msg here if you contacted him. Hopefully we can get this fixed and be left with just an awesome working phone!
I emailed the guy, it happened once a week when I was on the VZN rom.
dezoris, what rom are you using now? does it not get stuck in 1x?
just curious...
I had this problem on stock VZN ROM and still have it on MightyMike ROM...
Sent Kevin a message
I sent him one!
I haven't had my phone 2 months & this is pissing me off!
I have also had a complete loss of data connection period! Grrrrr
After doing the *228 & option 2 to sync with tower. Got WORSE!

I haven't had any problems like that with my Verizon Touch Pro 2, that goes for the stock Verizon ROM and the MightyMike one I'm currently using.
This has happened to me a couple of times. It is VERY annoying. and i KNOW it's not a signal issue. What kind of "debugging" should i do before i email the vzw manager guy? I don't want to send an email without doing a little debugging work. That way i seem like i know what i'm talking about.
PS. i agree, this is probably not an isolated issue.
I work at a large international airport in a metro area. It goes without saying there is a ton of cell capacity in the area.
Yet I continually drop to 1X when on a data connection. I always thought this was just "one of those things" or something to be expected. You are saying it is not but a bug in the product/ software / rom, etc?
Happens to be about once every other day. And I just soft reset and it goes back to normal.... Sucks I know.
Just stumbled on this thread and thought I would comment -- my TP2 is actually on Sprint and not VZW, but I've seen this problem fairly frequently even going back to my old Mogul/Titan, so it seems to be a legacy CDMA issue. I think there are two kinds of problems, though, so I am curious to know more about what people are experiencing.
First, as you know, incoming calls or SMS must drop the phone from EVDO to 1X -- this isn't usually a problem because it should snap right back to EVDO after the 1X packets are done. However, I have seen many occasions where it "sticks" on 1X *as long as the phone is still trying to transfer data* -- such as Exchange push or streaming Internet radio. If the phone keeps trying to access the data connection, it will stay in 1X indefinitely most of the time. If the data connection goes dormant for more than about 20 seconds, it seems to finally revert back to EVDO.
The other circumstance is where it seems to just drop to 1X and stay there, and not even cycling the radio on/off seems to make a difference -- you have to soft reset.
I guess what I am wanting to drill into is how many instances are of the first time and how many are of the second. It did take me a while to realize, for example, that if I got an SMS while listening to streaming radio, the data connection was going to drop to 1X and stay there until I closed the streaming radio app. Similarly, I often get as many as 2-3 emails a minute during peak times of the day (I know, my company needs to take some valium), so the constant Exchange syncs never give the data connection a long enough "break" to get back up to EVDO. The main point is, the first type of problem is more or less a CDMA protocol issue that we're probably stuck with, while the second type seems to be a definite bug with either the radio or the OS.
I notice the issue too, but worse it will go into and endless loop of popups letting me know of the situation and the only way to make them go away is to soft reset. Dismissing the popup just makes it come back again over and over. Calling this a legacy CDMA issue is bull as none of my other phones or Blackberries, even my piece of junk Storm have ever done this. Windows mobile needs to give us a decent radio to fix this. The only Verizon EVDO capable Winmobile device I have had that did not have this problem was the XV6700 so this has to be something to do with more recent devices. It has happened on HTC and Samsung devices, so it can't be manufacturer specific. It is the primary reason I moved most of my lines over to Blackberry. I got my wife one of those new Android phones, 1st the HTC one and when she decided she wanted a keyboard, the Moto one and neither one does this.
1x stuck
Same issues as everyone else here to.
i have found when i go to start/settings/connections and launch the comm manager, do do anything just launch it it corrects the issue.
thats strange but it has worked everytime for me.
Everyone whose having this issue on Verizon. Please please please email Kevin on post #1. Having one person as the sole contact on this issue WILL help get it worked out through Verizon. Kevin was very helpful and is a Tech Support Supervisor. Thanks!
Ok verified work around that works for me I'm on day 4 and im still on a EVDO connection.
1. Com manager
2. Press 3G connection and set your network type to auto.
3. dont press ok.
4. Press the X in the top right corner.
5. Soft reset.
So far this method has "fixed" my issue as of 4 days ago. Previously I would go 1 or 2 days before seeing the issue again.

I can't seem to find "3g Connection" as an option or setting under the com mananger. Am I looking in the wrong place? Which OS/ROM are you running?
I am on stock Verizon WinMo 6.1. Thanks for any help.
Sorry your right. Im running the CDMA energy rom. Yours should be stated as Data connection.
You should really consider upgrading your rom. I held out for a long time and just gave in.
I'm actually on verizon with tp2, Verizon is well aware of this issue(as far as i;m concerned). When I put on a custom rom, it showed up, however I needed to put back the default rom from verizon it went away. I put the energy rom back on and it's back. If verizon knows how to ship phones with that annoyance turned off can't we get a fix for the popups?
That pop up is most annoying!

Posible fix for stuck in 1x!
I'm going to go out on a limb here.
I posted in a coupl eother places and got no response on this which was original phone settings before I flashed
Same normal Phone settings for #777
BUT, the other read as follows:
VZWEmbedded
Log on: emsgsm.vzw3g.com
Pass: vzw (I tried our regular password & it worked)
In networking don't select on setup ie just your #777, set it to auto.
Here's my point:
No longer receiving multiple popups for: your device is registering on a voice line
More bars Show up now
Stay in 3g longer and now the phone calls up 3g for when data needs processing and data connection goes live as it should at this point.
Was using engery rom's nov 9 stable, worked with this switch
Now using Energys 6.5.3 28002 rom & working even better.
Running the same radio that came with phone version 1.88.
While i will drop periodically to 1x it does recover on it's own and isn't staying stuck.
Don't want to even look at 1x, update weather lol it works. So I am not to sure it's a hardware issue per say (maybe both who knows) since I have gotten rid of my popups. I'm not a programmer but sounds like a programming issue since it needs the 2nd set of connection strings.
What won't fix the issue is if you are in a bad area with very poor reception. I'm in the middle of a oak grove forest at the bottom of a hill and this is working for me.
Make sure you keep the 3g push in setting on and set to auto
Give ity a try!
Any thoughts on this?
oK AFTER much confusion on ppcgeeks, I need to calrify a few things.
This is a 2nd connection that you need to add.
The GSM is data, normally phone operates in cdma but it is making use of the gsm when over seas for email. It also uses gsm locally for data.
Since adding the 2nd connection all popups are gone. data connections are better on new rom then on stock rom.
If you've made use of JMZ Provisioing you already have the 1st connection under My ISP. Just add the 2nd as noted above and under select network make sure it is set to auto. This allows verizon to switch as needed.
This has been happening to me for about the past 2 weeks. I just e-mailed Kevin. I plan to take it to our on campus Verizon store next week.
I am running a stock ROM with SPB Powershell 3.5 on top of it. EVDO comes can goes. Usually once I try to use an app that requires data (Pocketwit, Opera or even ActiveSync) it drops me to 1X and never connects. I have also gotten several PPP (error code 11) errors. Before this time, the phone had been rock solid with EVDO.
Now my ActiveSync wont even work when I am at home. It only works at work due to being plugged in via USB.
Hope Kevin can help us get to the bottom of it.
I was stuck in 1X for the last few days. My problem was resolved by dialing *228 and pressing '1' to program.

[Q] Not registered on the network problems

I've read a lot on the internet but have not found a good answer for me. In certain locations, almost daily, I get either a "not registered on the network" message or a "sim not allowed ##3" message on my Infuse. If I switch the phone to airplane mode and then back off of airplane mode it always reconnects to the AT&T network. The problem started after I changed my ROM from Infused 1.5.3 to Zeus 6. I've flashed to Mind of Mac 1.4 but that didn't fix the problem. I've tried a new SIM card, different APN settings and several other changes, but it didn't help. If I have a good 4g connection it never has the problem. It never re-registers on the network until I do the airplane mode on and off thing or reboot the phone. My iemi number shows up weird on the phone too. What is the best way to fix this problem? Thanks.
No one has a clue?
No one has a clue how to fix the problem? It happens when I lose 3g or 4g connection.
What modem do you have?

I currently have UCLB3. I have tried a few different ones but it does the same thing with each one I've tried.
Sounds like you know what you are doing , unfortunately it sounds like a hardware issue. If going to settings > mobile networks > network operators and choosing AT&T does not fix it the only thing to suggest is return for repair or exchange. As you know, you will have to return it to stock so after you do that you may want to test it one more time. Sorry, not the answer you wanted but the best answer I have, Regards.

From recent experience - I would avoid using the fixes listed above as they will change your IMEI.
I say this as I was having a similar issue -- I had been running on the ParanoidAndroid ICS rom for a few days and my I997 started to do the same thing. Network connection was fine most of the time but it would occasionally drop out to no network. Except swapping between airplane mode didnt always fix it. If i rebooted the phone and it would pop up with "Unknown" Baseband Version, and no IMEI/IME SV until it connected again... whenever it decided to do so.
I flashed a few different modems to no avail.
Used GTG's stock restore... and it still showed no baseband or IMEI.
Searched through everything i could find and I found the 2 above posts. Being the cautious person that I am, I was skeptical to run the "fix" since I know playing with the efs folder can do.. fun things.. I backed it up with EFS Pro.
http://forum.xda-developers.com/showthread.php?t=1308546
So after that - I did the fix from those two posts. It worked. I got a signal. HUZZAH. But I could only make a few calls before it would drop out, and I couldn't send or receive text messages at all they would just stall and error out.
So I took a look at the IMEI again and noticed that it was NOT *my* IMEI, it was presumably the imei of the person who Truckerglenn got the backup from so long ago.
Figured at this point my phone is going to have to go back to Samsung to fix since it's still dropping out, the IMEI is wrong and I can't send texts
Can't break it anymore than it's already broken right?
Go back into root browser, delete the EFS folder entirely. *poof* gone. Reboot. Use EFS Pro to restore the backup I had created (GOOD THING!) phone reboots. Instantly picks up the signal again, I get 15 text messages, 2 voicemails AND my IMEI shows what it should be now.
*HOPEFULLY* it holds onto its connection now. If not, back to stock and back to samsung it goes - now with the correct IMEI. heh
Sorry for the long story
Thanks! May have found a partial fix.
Thanks for the tips and information. I think I may have found a partial fix. It seems that picking the "WCMDA only" in the "Network Mode" options seems to solve the problem for me. If it is set on "GSM/WCCMA (auto mode)" option, it seems to cause the "SIM not allowed ##3" or the "not registered on the network" problem when I am in an area where the 4G or 3G signal is weak. I will do some more testing. It appears that if I don't have 3G or 4G available in any given location my phone won't connect to the cell towers at all even though other users can connect without any problems. Does this give anyone any other ideas? Do I possibly just need new APN settings?
Have you tried flashing a new radio? Does a complete wipe and restore to UCLB3 make any difference?
Has any of these roms/firmwares that you flashed been done so through Aroma installer? I know Aroma gives you the option to change modems, and if your download was buggered that could have caused it.
I'm just tossing ideas around here... I'm up early and looking to help.
The work around works
Yes, I have flashed the radio but that didn't help. I have discovered the "fix" is to set my phone on "WCDMA only". It seems that the phone will only work if 4G or 3G is available. I am not longer getting the original error messages. So that's a good thing. If I ever go to where 3G and/or 4G is not available I will have to try something else. Thanks for all the replies.

Constant "Emergency calls only" and no signal

Heyho,
about three weeks ago, my N5 suddenly lost it's signal over night and shows me "Emergency calls only" and it won't register into any network, just giving "Selected network unavailable".
When this occured my N5 had 4.4.2 stock ROM and rooted. I've unrooted it and updated to 4.4.4, but I still got the same problem.
Problem occurs with any simcard, while simcard works with other phones just fine.
Have deleted and reconfigured APN, but didn't make any difference.
I get a signal every few days, but I still can't receive text/calls or call/text anyone and my mobile data doesn't work.
I even tried to downgrade to 4.4, but that didn't solve my problem either...
I'm from Germany, but in New Zealand at the moment, so I really need my phone in case of emergencies and to stay in touch with family/friends.
I have been searching for a solution since it started, but have not been able to find anything that worked.
Sending it back to Google isn't an option right now because I am travelling.
I am really thankfull for any suggestions or if anyone knows how to fix this problem!
Cheers
Have you checked to make sure the network setting says 2g/3g/LTE preferred. Because I had this problem when it was switched to 2g only and was fixed by the above option
If the above fails trying going to your dialer and typing *#*#4636#*#*. Go into phone information and you should see a drop down box to select your network mode. Play around with those until you get a signal but you might not want to try CDMA options (WCDMA is ok) since you're on a GSM network.
Sent from my Nexus 5 using XDA Free mobile app
had exactly the same issue as you mentioned. Nexus 5 tends to lose network without any logical explanation and it tends to work at one place but stop showing network if you walk half a mile down the road (or may not show any network anywhere). Google has released an update in June in which they have updated the modem to solve the problem..given that I am in India and the June update was for India, Australia and Newzeland, it worked like a charm for me (all i had to do was flash the modem from twrp)..people as far away as netherlands have reported the modem to work for them..
NOTE: IF U INTEND TO FLASH THE LATEST MODEM, DO NOT FORGET TO TAKE A BACKUP OF YOUR CURRENT MODEM PRIOR TO FLASHING THE NEW ONE..
check your sim card. if you can, try someone elses.
Alright,
I've tried every thing again so far, but nothing seems to work.
Sitting in the library, I noticed that I get a signal, when connected to WiFi, which stays for 1-2 hours after disconnecting.
But I still can't make any calls or text and mobile data doesn't work though the APN is correctly configured and and data enabled.
I really hope to be able to solve this problem somehow, don't want to put aside my beloved N5 :/

Edit: Haven't found any solution so far and bought a new phone for the moment until I'm able to send it back to Google.
Might be an hardware issue and not software related.

Can't get connection to ANY carrier

Hi! I'm having some mayor problems with my OnePlus One.
For some time I have had problems getting calls and sms when using 4G but it seemed to be a problem with my carrier but 2 weeks ago I dropped my phone and the screen broke so I bought a new screen and replaced it. After that the connection to my carrier dropped randomly and now after trying to fix it in different ways I can't get any connection at all with any carrier !
What I have tried so far:
Factory reset
Reinstalled CM
Put paper under the sim for tighter fit
Turned the radio off and on and restart phone
Change pin code
Replace sim-card
Tried different carriers on my phone (my simcard worked on other phones so it is the OPO that is the problem)
Total restore by fastboot-flashing
Installed OxigenOS 2
Tried all modems from the modem collection on CM and Oxigen.
Retyped the APN by hand
Opened the phone again and checked that all cables are connected well
Tried manualy connect to my carrier under Network Operators
For a short time of maximum 10 seconds I got a 4G connection twice in now 3 days of trying but then it stops working again. It feels like a hardware problem BUT I can see a lot of different carriers under Network Operators but when trying to connect it loads for ever and then says "Can't register to your carrier". I called my carrier and thay said nothing was wrong from their end and when I tried on other phones it worked flawlessly.
I'm really out of ideas now and I don't know where to go from here. I really hope someone of you knows that might be the problem!
Thank you so much!
If imei present you can try mobile phone exchange offer on flip kart like online stores. When this happened to my phone I did it , very easy.
Sometimes opo dont search available network or wont register on any network.
Sulution: go to access point and reset it to default first then go to network and try to search for network n if ur able to search then try ro register manually and if it does not work then go to dialer and dial *#*#4636#*#* then click phone info and select the lte/gsm ato prl mode and then click turn radio off and again tuen it onn then smsc refresh and update ( i dnt remember it correctly) if that dnt help then ur network antena is damaged

loosing reception/signal on my s8+

Somehow my s8+ loosing reception all the suddenly.
phone has never been dropped.
i am loosing cellular signal all the time. no mattere where i am.
first i thought it was software problem, an did all the right things. safe mode, checking third party apps,
hard reset, an all that.
then i downgraded the room back oreo to see if it helped, no luck ;(
changing sim did NOT help either.
any suggestions? i have no warranty left on the phone as it a bit over 2 years old.
Mine is doing the same thing, even with wifi. It started after the most recent update. I have been googling, but haven't found much so I assumed that it was localized to me. I have never had connectivity issues with this phone before.

I am having the exact same issue, it all happened after I updated to android 9, even if you downgrade back to 8 it doesn't fix the issue, has anyone managed to find a solution ? Like henbone11 mentioned suggested sites with fixes from Google do not work. Thanks in advance
I was thinking bad modem software? Is it possible to get a older modemsoftware onto the phone with PIE installed?
Same problem here. Have not done any mods, always accepted the official updates.
Cant make or receive calls. (sometimes can make one or two calls right after restart). I do get text message notifications about missed calls. GSM data not working (sometimes seems to work for a bit but not enough to load a page or use maps.
WiFi and Bluetooth still work for me. so I'm using the s8 with another older phone for WiFi hotspot and calling.
Have done full factory reset, uninstalled all apps aso. Nothing brings it back - phone repair shops say they haven't heard s8 having these problems.
I have the same issue.
One day after I restarted my phone, it suddenly said no network connection. I did factory reset too, didnt fix it. Changed sim cards, still error.
I downloaded a widget that was supposed to turn the cell radio on and off. Cant turn the cell radio on either
Network Connection on s8

Hi,
This issue is quite easy to fix. As modem performance (connectivity) is linked to model configuration. Another word for this is CSC.
It is fine to change your CSC. Download a benchmark tool to monitor your connectivity and record values and do not feel afraid to update / change your CSC.
It can take a while to find the right one for you, not it will be worth it. Don't worry.
Note: CSC changer can be easily found in XDA.
Note: a restart may be required to take the configuration into account.

Hi.. i want to do your solution.
What benchmark tool to use? And is there a tutorial for the process?
Thank you so much for the idea.
I moved to another country and used a local sim card, worked for a couple of days and then it's suddenly no network.
IMEi still ok.
Phone still detects my number.
I've tried
resetting network setting
factory reset
Flashing latest unbranded firmware via Odin
Still no luck.
The mobile radio switch won't turn on.
Ping test fails.
Sometimes I wonder if this is a hardware issue.

Why would this work? Phone worked normally before. Same country/same provider. Sometimes still connects to data network for a minute and then drops all cellular connection again.
Why would changing CSC work.
Asking because changing CSC is not easy for me and I don't see why would I need to change it if it worked perfectly before. NFC payments worked(still work) , data/voice calls worked perfectly for 2 years. Then suddenly didn't.
