MDA Pro - Not ringing when I phone it :(

Dunno what is going on here - I had this problem occasionally with E200 / C500 on Orange, but not to this extent.
Sat at my desk, I suddenly get a Voicemail notification. Strange, as the phone hasn't rung. So I decide to test it.
I get NO ringtone on the phone I'm calling from. Nothing at all. Then it cuts straight to VM. (Phone is sat with full signal, and connected to UMTS network). I phoned 5 times, all with the same result.
Then I hung up the UMTS. Same thing happened.
I did a soft reset and left it in clamshell mode, and phoned again. This time I could clearly hear the ringing on the phone I was calling from, but the device didn't ring / vibrate or anything.
I opened it up and had a message "The phone operation failed" so I hit OK on this and closed it back up again. Phoned it again and this time it rang properly. I hung up before connecting, and got the "Missed call" notification.
Its not (entirely) down to being connected to UMTS - as my phone reconnects automatically as soon as it starts up.
Anyway, having dismissed the "You have a missed call" notification, I tried again. Its back to its original state now, no ringing heard on the phone you call from, and nothing on the phone itself. I only got ONE missed call notification, despite calling it around 7 or 8 times in all.
What the hell is going on here? It almost seems like the phone itself signals to the network that it is totally unreachable (hence no ringing heard by the caller).

I assume you haven't set up diverts or anything?
Get your network provider to do a test and see if they can give you any further information.
Failing that, it's possible that if you stopped the ExtROM from fully installing, it could be causing problems? Or maybe even some sort of task manager may be 'killing' the phone services?

I hadn't set any diverts, and it was the oddly random nature that was cause for concern - it worked after the soft reset, but didn't work beforehand. I can't be doing with a phone that, for its own reasons, refuses to aknowledge an inbound call! This should take precedence over anything else the "phone" is doing at the time, surely...
I've got T Mobile to send me out a reset of my profile (a text message which I delete, then power off the device) and I'll see how it goes.
I did have SBP PocketPlus installed, but no longer... I've not got much installed at all, at the moment.
Strongly considering flashing to the iMate ROM at this moment!

After removing the battery I retested. It was fine.
After writing the last post, I retested again and its broken again.
B*llocks.

The same as you my XDA Exec, oftern misses calls, ( you ring your self and hear it reing bu the phone makes no noise) i also had the same on my XDA2i, and yes removing the battery fixes it for a while.
Also mine when it looses service ( witch is oftern ) it will not go back into service until i soft reset it

Hmm, sorry no clue.
I have a JasJar and no-one has told me off for missing their calls. (I take quite a few from work, but rarely make any myself)
Maybe try a ROM flash, but I'm sure other Exec users are not having these problems, so it sounds like it might be something other than a ROM issue?

I've just stuck the iMate Rom on it. Was probably going to do it anyway, but didn't want to break my TomTom setup...
I'll do some testing and will repost on this thread with my findings.

I'm still getting the problem with the iMate ROm installed.
When I go to the Phone settings, it thinks I'm on the UMTS T-Mobile UK network. Now I'm sure this is fine for data, but maybe its not OK for voice, or something like that?
Can anyone let me know what they have in those settings?

Spotted this too on the Jasjar - can't pin down why though as it only appeqars to have started recently

I'm becoming certain that my data connection is effectively hogging the phone and not allowing voice traffic. I just had problems sending a text message. Every time I hit send, it failed (about 6 times) and went into drafts. To get it to sent, I hung up my active data connection and tried again, and it went immediately.
This is a nightmare, as the device HAS to perform both voice and data functions. I want an always-on data device, but the data MUST be interuptable by inbound / outbound phonecalls as well as notifications (SMS etc).

Right...
I've dropped down to GSM instead of 3G by removing the "Auto" setting from the Band option within the Phone Settings. This appears to have solved the problem.
From looking at the network, it appeared my phone was always connecting to a network called "UMTS T Mobile" (this was even displayed on the occasional incoming call that worked as the carrier). I'm certain this is what is causing the problems. After a Soft Reset, it would still connect to this, as my OTA ActiveSync connection would start up...
Having changed to GSM instead, I'm now connecting to "T Mobile UK" as my carrier - and this is allowing full inbound/outbound functionality - albeit only with GPRS data connectivity.

I'm on T-Mobile UK, and MSN Messenger will happily be interrupted when I get a voice call?
I'm lucky enough to live and work in an area where I'm only ever connected to UMTS (although the setting on my phone is "Auto"). I'm 99% certain that I can get calls every time, and having tested it just now a couple of times it's working without any problems, so there must be something that'll sort out your problem?

I'm lucky enough to live and work in an area immediately covered by whatever equipment may (or may not) be located a T Mobile's head office... :roll:
I cannot discount the possibility that they've erected a UMTS cell which they "tinker with", which may (or, indeed, may not) be causing my problems...
I guess next time I'm out of the area, and in a 3G coverage area elsewhere, I will revert and test it.
In the meantime, they've asked me to test by switching back to "Auto" and trying to phone my phone once in a while, taking note of when I call and whether I get through, and they'll endeavour to trace those calls and find out what is going on...

I hope you'll be sending them an invoice!?!

I have this problem now. I only noticed it after a ROM upgrade (to the latest TMUK ROM). What fixed your problem in the end?

Hi All
I have had a very similar problem and have been discussing it in a separate thread.
http://forum.xda-developers.com/viewtopic.php?t=62863
As you will see, it seems to me that it is a T-Mobile issue, but they don't acknowledge that it is a fault. I don't get the same problem when I put an O2 sim in my Exec.
Other than downgrading to GPRS, I don't think there is any fix.
Mark

Mark, I've had a thought. Do you (like me) have an old 5v T-Mobile SIM.
These SIM’s can be identified either by SIM serial number 893044 05 or 16 – up to and including 893044 50. SIMs with serial numbers 893044 52 and above will be ok- anything lower is likely to be a 5v.
There was an issue when I 1st got my MDA Pro. It had to be network unlocked by T-Mobile for it to work with my SIM. Is it possible that the ROM update as "re-awakend" this problem?
(Also posted in thread you link to)

Thanks for the idea, Slave1, but I don't think that is the cause of the problem. My SIM doesn't have a serial number anything like those you suggested (it starts 060080...) and I only got it a couple of months old and so I am sure that it is a 3G one.
However, now that you mention it, I did have a problem getting the SIM to work when I first got it. I had to get on to Customer Services to get them to register it on the network becuase, they said, the shop hadn't registered it correctly!

All SIMs are usable with 3G (it's the handset that make the difference)

That's a different issue but just as frustrating.
I had another though. Is anyone using a T-Mobile SIM in an XDA Exec (or just using an O2 ROM) having the same problem?
Could it be a ROM issue?

Your SIM card does not allow a connection to this network

I'm curious to know if anyone with a non t-mobile g1 experienced the same.
My phone was working fine this morning until it stop being able to register on the network with the above error. The only thing I did with it this morning was to put on a screen protector. I doubt it's related
A reboot in recovery mode and a wipe fixed the network registration issue so I guess some data were corrupted.

Hi.
I have the same problem now. Have tried to hardreset but still No service..
Can you help me??

Just get a new sim card

I have the same problem now - but it is extremely frustrating and I have tried, since I first wrote what is below to downgrade - but cupcake will not let me.
I have an unlocked - but also unrooted G1. I use it in Europe and in the US. While in Europe I got the message to upgrade and without thinking I did. Then while in Europe I could no longer use the phone as a phone. The update went fine and I had ‘cupcake’ but any SIM I put in (T-mobile, BASE etc) there was no signal and when I went to do it manually I got the message “your SIM does not allow a connection to this network”
So I did a hard reset, but then I could not get pas the start screen since I had no data connection (but I did seem to have phone connection again.
In a layover in Atlanta I tried again - I was able to log in and set up and all was great and good. I should note that I have an old data plan and use an alternative APN to access data. This worked fine in Atlanata where there is 3g connection.
Back home no win Florida… no phone service - same as in Brussels. same message. Worth noting - there is no T-mobile 3G service where I live.
After thinking about this for a while I am wondering if somehow I did not get the correct or full radio update…
if this is true - do you have any idea how to remedy the situation or how I would know if this is the problem?
I appreciate any help.

I have the same problem, any news about this?

I had this issue randomly about a week ago. Reboots didn't work, and I really didn't want to go through a wipe/re-flash. I called T-Mobile, they had me reboot [after I told them I had already done it] --- they ended up deleting me from the network and reboot my phone again, which apparently re-registered me on their network.
This is on T-Mobile US (SW Ohio to be specific)

Does anyone has any news about that? I was told that this might be a radio issue, so I tried to downgrade my celphone to version 62.33.20.0H_1.22.12.29, (using fw 1.0 too), it worked for some time then suddenly it gave me the same error that my sim card it's does not allow to this network, so I forced, again, to my network and the same message appear, I tried this sim in another celphone and worked, I tried another sim on my G1 and it didn't worked, this celphone was working when I lived in the US, but here in Brazil it's not working just like there.. my guess is that the Radio in other countries has any bug, does anyone here was able to fix that? any further advice?
thanks.

weird, i have this issue tonight on one of my unlocked g1's that would normally be working on ATT.
I'll update this post if/when I find a cure.

I've been having the same issue of and on for a couple of months now with a G1 on Dutch T-mobile with dutch T-mobile SIM card, which is odd. Running CM mods so maybe the fact that i'm runnig non stock fw causes this?

I get this problem from time to time. Almost never around town where coverage is good, but when I'm on the road in a lot of places where coverage from any provider is poor this happens, especially if it keeps having to switch back and forth between roaming and not roaming. I even get this on T-Mobile and they are my provider. Usually a reboot fixes it, but not always. I've never had it last more than an hour though.

Try reflashing the radio on your phone. Sometimes this helps solve odd connection issues.

according to my tries, this isn't related at all. i'd like to check in on this thread and see a known fix instead of maybes.

Had the same problem
I had this problem about a month ago, apparently simcards can go bad after a while; I had the same simcard for 5 years and it became unreadable. I went to a t-mobile dealer, bought a new simcard for $20, and I was finally able to get my connection back. It's a bit of an expensive route, but at least I didn't have to replace the entire phone.

my att sim is 4+ years old, but works fine in all but one phone in question, with the above error. also, I have a brand new tmo sim that throws the same error, only on that one phone- which leads me to believe its not a sim CARD problem at all.
all my phones are unlocked, in case of weird problems with any gsm carrier.

Looking at your sig, is this one of the phones with gnav? Because some of the earlier techniques of installing gnav have resulted in a "no service" signal. If it is one of the phones with gnav, try pushing the old build.prop files back into the phone.

gave it a shot, used the normal build.trout... and same results. surely someone at tmobile is familiar with this problem ?

Same issue.
I am running cyanogenMod-4.2.12.2 with radio v. 2.22.19.26I on a t-mobile mytouch. I will lose service and the phone will not automatically reconnect to the network. When I manually select my network (wind mobile) it sometimes connects fine and sometimes I get a "your sim card does not allow a
connection to this network" error and must reset. I found this thread code.google.com/p/android/issues/detail?id=2845 where dozens of people running all different hardware (G1-hero) and all different software (stock cupcake, cyanogen, etc) all experiencing same problem. It seems this problem is happening regardless of the network (T-mobile, vodafone, orange & wind mobile). The problem seems to be happening through all different variables. Changing sims does not seem to fix it. Anyone have any ideas, this is very frustrating.

I've seen this issue as well, with the new Canadian provider Wind Mobile.
The issue seems to coincide with new towers being added onto the network. There are minor service disruptions that result in the network being temporarily screwed up. Going into and out of airplane mode seems to fix it every time.
Also note: These minor service disruptions do NOT ONLY affect my phone, but others (different brands) as well.
They've gotten better at adding towers without blowing up the whole network. It started out happening a few times every day. In the last week it happened only once.
Funny observation: When this happens, the DATA SERVICE recovers automatically, even though the signal gauge remains in X-no service mode. This part is probably android and/or dream related.

It is related with network
I've started to have the same issue tonight. I've rebooted several times and changed the SIM card with another from another operator but nothing helped.
Then i remembered that since I bring this phone from Belgium to Turkey, the regulations in Turkey requires the phone to be registered with its IMEI number to the telecomunications supreme board.
Altough i had initiated the registration process months ago, i thought that there may have been a problem with the registration, so i checked the boards web page.
It turned out that my IMEI is not registered and this most probably is the reason for the not allowed connection.
Tomorrow i will try to reach the board officials and i hope it solves the issue.

do you know what happened? i having the same issue right now and cant seem to find a way to solve it..

[URGENT] X1 can't find T-mobile signal

I have used my x1 for four months in America with T-mobile. The phone had no problem until yesterday. However, yesterday, the phone began to lose signal and automatically rebooted several times. Then, finally, from the afternoon, the phone totally lost the signal, and kept looking the signal.
I took out my sim card and plugged into another cell phone and it worked. So, I thought it was the problem of the rom. (I was using Touch-IT 4.5) I downloaded the new version of the rom, Touch-IT 5.6, then flashed it. However, it did not solve the problem. So, I flashed with the original SE rom. However, the phone didn't work either.
I contacted T-mobile, and there was not problem on the signal on my region. I thought it might the problem of data plan since I do not use data plan. So I used Advanced config and killed every option for data plan. However, it still does not work. I tried to do settings manually. changing band, carrier, and every possible options, but it does not work.
Interestingly, the phone worked two times today for a short amount of the time. However, after the reset, it is gone. Other than phone function, I do not see any problem.
Even now the phone keeps searching the signal. What can I do? I read another article that is similar to my case, and they say even after changing the sim card, it does not work.
Anyone has the same issue? What can I do? My phone is dead for two days, and it messes up so many things. Please somebody help me.

Have you tried redoing the connection setup?

try clicking on signal antenna then enter settings click on network and manual select your network, will take a few mins to find networks if it connects manualy just select auto again and hopefully it will fix it., worked with mine.

Thank you guys
Thank you guys. Yes, I have tried both of them, but it still does not work.
In Connection setup, I chose United States and T-mobile, and the screen to choose between T-mobile and At&t. I select T-mobile, and click Register. Then, it goes to the searching mode again, and nothing happens.
I assume that somehow, the phone finds networks, since it does show the options to choose (T-mobile, At&t). But something is not right, and it messes the set up. I do not know why.

[Q] No connection for calls/SMS but data works?

My SIM unlocked Defy has been sitting unused on the shelf for several months - I did plan to sell it after upgrading to an Atrix, but never quite found the time to sort it out.
I've now decided to pass the Defy on to my girlfriend as a Christmas present (yeah, I'm a tightwad ), but have not been able to get it to work correctly.
The problem is this. The Defy will not connect to the network to send or receive calls or SMS messages. However, the phone can connect to data services via 3G (even though, on my Giffgaff SIM, it gives some sort of error message saying connection will not be possible, before accessing the internet without problems!).
I've tried:
Multiple Basebands - including the various ones I used previously without any problems.
Multiple ROMs - CM7, MIUI, WajkIUI installed via CWM and a couple of Froyo SBFs installed using RSD. All these ROMs show the same characteristics - no calls or SMS but Data connections work.
Multiple SIMs on different networks. The Defy was originally a T-Mobile device but I unlocked this using a code from one of the Unlock sites and used it with an Orange SIM then my Giffgaff SIM with no problems. Now, the very same Giffgaff SIM shows the call/SMS problem. My girlfriend's T-Mobile SIM appears to be recognised normally and the network seems to be working but all calls and SMS messages fail instantly.
Multiple Wipes/Resets using both CWM and the stock recovery. None has resolved the problem.
A quick Google found the following link:
http://thewichitacomputerguy.com/blog/how-i-fixed-your-sim-card-does-not-allow-connection-network-g1
Unfortunately, I've tried everything recommended on that page without success.
Anybody have experience of this problems on their Defy and, if so, can anybody tell me how I can fix it?
I promised my girlfriend a phone so, if I can't get this Defy working properly, it's going to cost me a few quid so I would appreciate any assistance!

I've since discovered that my problematic Defy appears to have been blacklisted, almost certainly by accident by those wonderfully incompetent folks at Orange. Here's more information on a problem which has occurred with quite a few people here in the UK following the merger of the Orange/t-mobile networks in mid-December:
http://forums.moneysavingexpert.com/showthread.php?t=3677593
I bought the phone on eBay from a seller and used it for around six months without any problems so I think it incredibly unlikely that the blacklisting is valid - I mean, who would report a phone as stolen around 8 months after it was taken?!?
Just waiting to hear back from the eBay seller to see if he can provide me with his original proof of purchase for the phone so I can get the blacklisting lifted. I don't rate my chances all that highly.

Hi all. sorry to revive a few month old thread, but at least I'm not creating a whole new one!
I have a Motorola Defy. Generally I'm pretty geeky, but I decided to root it at install ICS 4.0.4... it all went well... eventually. However I have no conectivity to my network. It will not send or receive texts calls or data to the network. Wifi does work still.
Honestly I'm done screwing around with it. I just want to restore it back to original factory settings and admit defeat. Where can I find the original firmware that will work In canada on the Telus network? This is my only phone, I have no other cell and no landline so I'm kinda in a pickle and would appreciate anything you could do to help me get up and running again.
If there is any more info you need just ask, I'll try to get it for you.

Try it with this baseband switcher. Maybe it will help you.

Thanks! I actually just saw your post, but I figured that out all by myself! It did work though! I appreciate the reply!

ok new problem... everytime I shut off my phone it reverts back to the wrong baseband. any idea on how to keep it on the new one? every time i reboot I have to swithc baseband then do a restart. it them switches and works perfect. If i shut the phone off it reverts and I have to go over it all over again.

Try to convert defy baseband switcher to a system app with Titanium backup.

[Q] Unlocked G2 on emergency calls mode only.

Hi all,
This is my case with the hope of getting any help or lead in order to solve my problem:
After a long research I bought an brand new LG D800 already sim unlocked in the US and brought it to my country (Costa Rica). I made sure the frequencies supported by the D800 are the ones used in my country. In fact 2 years ago I bought another phone that uses same frequencies and had had no problems ever.
As soon as getting in my country I placed the SIM card I'm using in my current phone into the G2 and it recognized the signal and connected to the operators network. I started to make and receive calls almost immediately, and also SMS' without issues. So I started to migrate all my data from the current phone into the G2. I used Titanium Backup for this, so I rooted first the phone using the guide I found here, and basically what I did is installed the apps from Google Play and then restored data using Titanium.
After the second day of use suddenly I found out that I wasn't able to make or receive calls since the phone lost connection to the operators network only allowing emergency calls but the signal bars were full (see scren capture). Sometimes when restarting the phone I get "Phone not allowed MM6" message just after the phone tries to connect to the operators network.
Went to the phone company offices and they tried to help me and made some simple tests, without changing anything inside, such as checking Android's network configurations, checking in their system to verify the IMEI wasn't blocked or reported (the IMEI is clean), also checked the sim configuration and after more than 45 minutes they were not able to find anything wrong in their system or with the phone itself. They also made a final test taking a working sim and put it into the G2 and gatting same emergency calls mode, and took my sim from the G2 and put it in another phone and that phone was able to make and receive calls. So they concluded that the phone has a "built-in" configuration or damage that impedes the phone to connect to the network. They finally suggested to ask the seller to apply the waranty, which is not a viable option since I'm not in the US anymore. This G2 is using the stock ROM (see screen captured).
I've been in close contact with the seller, and he had shown interest in this case but unfortunately hasn't been able to provide much support or help to solve the issue. He reports that he has contacted other buyers of this same phone, also sim unlocked by him, and they all are using their G2s normally. Didn't provide where their locations are tough.
My own conclusions here are that the G2 IMEI is not blocked by the phone company, that there is some kind of fault in the phone that when trying to connect to the network, the network doesn't "like" and rejects connection, althought it worked at the begining, and I'm not able to determine if the fault is software or it's in the hardware of the phone.
So I'm trying to understand what my options are at this moment:
Try to return the phone to the seller, or ask an LG representative in my country to change the unit. Which seems to be very difficult.
Reflash the unit with a stock ROM and reestablish the warranty. But being unsure if this will solve the issue.
Reflash the unit with a new ROM and loose the warranty, and again, being unsure the issue will be solved.
I'm really frustrated and at this moment and have no idea on what to do.
Any ideas or insight will be appreciated.
Thanks.
NOTE: I reinitialized the unit and lost any signal (see screenshots) but received update notifications from Google Play and was able to upload the screenshots into my Dropbox although no signal is shown in the status bar and no WiFi connection is established, only data connection thru APN (I Assume).

Go into status, what's IMEI say?
Sounds like EFS issues. I take it you didn't back it up after setting up on carrier and flashing?
Of so, you have some manual work to do with diag mode and a couple apps via pc.

Hi Steamer;
Under status I see 3 items:
1) Phone Number: shows"Unknown".
2) IMEI: shows the number printed on the box, on a sticker on phone's back.
3) IMEI SV: shows"03".
Where can I learn more about EFS issues? Are there tutorials?
As you say I haven't done any backup thing.

Hi again Steamer:
After reading quite a bit about EFS issues now I understand much better what you meant with your post.
And as you said I didn't back up efs folder, I even didn't flash any ROM yet in the unit. The only thing I did was a 'hard reset' to the unit using the Power + Vol. Down method, after having several 'com.android.phone' errors due to backing up data from Titanium.
The phone went to factory state, I put the sim card and everything went back to normal again, meaning that I was able to make and receive calls. Like 4 hours later the phone went to emergency calls only mode, and from then on I'm not able to take it out of that mode.
So I wonder if the efs folder could corrupt after that factory reset. Is it possible?
Thanks again and any light is greatly appreciated.

It is not in its own partition on this device, but in system. A hard reset shouldn't have caused corruption, but it is not impossible. Your IMEI is intact then, that is good. From what you said about it working partially, your EFS is most likely fine as well. There is a thread here to get files with custom recovery zip file, or you can use adb commands to do it yourself. I don't have guides off hand, but Google is your friend, just specified this phone in searches. Try a new SIM. Sounds more like SIM /carrier issue now as you are out of "activation". That is why emergency is popped and unknown number. The SIM itself may and most likely is bad(or carrier has an issue with your account), in turn it can't communicate with the server causing non activation on network search. Priority to SIM.

I had the same issues. Bought in Us using now in India. Go to settings..tethering&networks.. mobile networks... international data roaming and select standard data. Switch off and switch on your phone .
This will happen when you use, internet over gsm. If you disable internet or if your phone loses signal while switching between edge and 3g/4g data, this is tend to happen.

Similar Problem
I have an lg vs980 and I was using it with H2O wireless and later I changed to Simple Mobile. I'm living in Puerto Rico. The phone was working all right and, suddenly, one day it was always displaying 'emergency calls only'.
I did factory reset, then I reflashed stock lollipop and it was like nothing happened, keeps displaying 'emergency calls only'.
Then I found this post http://forum.xda-developers.com/show....php?t=2394689 and applied the patch but didn't seem to resolve the problem.
As a last resort I tried flashing cm 12.1 and before first boot applied the patch from the cited thread but no result, keeps displaying 'emergency calls only'.
Has anyone found a solution to this problem?
