Weirdest Problem Ever..

I have this weird problem with the JJ. I have 2 SIM's with 2 different Operators. The JJ works just fine with one SIM .....
BUT, when I insert the other SIM, I can make calls normally, but I can receive only ONE call (i mean it, ONE), after that the damn thing won't receive calls anymore! (Like the phone is turned off or unreachable)
After trying to make calls for several times it does work, but again, one incoming call and that's it.
I tried that SIM in the 8800, it works just great.
Anybody has an idea on what's going on?
Thank you guys..
PS! I did post this in another topic, but needed some attnetion from you guys, so posted it in a new topic!

It is SIM free btw ..

Come on guys, 80 views and not a single reply.
I need to you that SIM in the JJ.
Could it work by a Radio upgrade or something?

OK, please tell us which version of ROM and radio stack you have.

Sure,
ROM 1.30.69
Radio 1.09.00
Thank you Richard.

the reason there are 80 reviews and no replies is cause nobody knows.
this is an anomoly, way out in left field, that I have never seen ever in all of the forums.
1. get a new sim card
2. get a new sim supplier
3. stop swapping them, and use the one that works
4. take the phone back under warranty and have them fix it.

Tried a colleagues sim card with the same operator and the same happened.. unfortunately there are no other sim suppliers.
the reason i want to use this sim in the jasjar is that my corporate email doesn't work with the other operator, there is some routing problem to our email server.
but why this sim doesn't work properly while the other does. its really confusing.

Throw this thought in.....
Could some settings relating to the "phone" usage be stored in the universal's registry that conflict with the other SIM card thats being used. Are both cards UMTS?

Here is a thought, Is the SIM with corporate e-mail the one that is not working? I have a T-mobile account with Blackberry BES and a Cingular account, two different SIM cards. Both work fine but the TMobile card will not work all the time with the blackberry connect software I have loaded up on my Exec. I called TMobile and they reset my "LOCAL Data" from thier switch and now it works fine.
Your carrier may have to reset some things for you to get your card working again. Just give them a ring and ask them to help you sort it out.

No they aren't ... I tried to hard reset the Universal with that SIM installed, nothing changed, still can't receive calls.
And once the problem happens, GPRS won't connect as well..

Already called them, they can do nothing about it, I traced our mail server using their GPRS, it stops some where is London! :lol:
I will try to down-grade the Jasjar with the old firmware. It might work :?:
Thanks buddies!

Can the Radio only be downgraded? Or I will have to downgrade the ROM as well?

You can downgrade the radio only, Find the radio you want on the ftp and then upgrade or downgrade just that

Here is what I tried so far..
1) Installing Qtek latest ROM, still didn't work.
2) Downgraded to Radio 1.06.00 and the problem is still there!! :evil:
Looks like I will be selling the JASJAR as soon as the P990i is here! :evil: :evil:

I suspect troubling SIM is UMTS (3G) enabled, AND has poor 3G coverage. JJ sees UMTS and spends its time trying to connect, but can't quite pull it off. I'm battling with this and trawling this board indicates that this is the issue; weak UMTS which you only experience witht he one SIM.

cingular gsm service dropping on 8525

i have a cingular 8525 and since yesterday, it keeps dropping my gsm service completely. like i look at my phone and there is an "X" on the service bars, and the service LED is not flashing. if i soft reset the device, or shut the phone part off and back on, it picks up service again (full bars, as usual). also, i tried plugging my SIM back into my old treo 650, and i dont see this problem. is it related to the 3g network? i haven't made any software changes since yesterday. faulty hardware? really frustrating, help would be appreciated. thanks.

shouldnt be caused by the 3g network, do you have the white 3G sim with the orange flaming 3G on it? This could also very well be hardware or the radio... so many variable with this... i would vote for 3 possible issues, either hardware, radio rom, or sim card.. take your pick.. the sim will be the easiest to try, if you dont have the white 3G then just walk into a cingular store, tell them they sold you the 8525 without the 3G sim and they will replace it for free.. well they did with me anyway

the only disconcerting thing is that i had the HTC TyTn for a month before i got the 8525, and i never had this problem with it, same sim and everything.

here's a thread about it on the cingular customer forums, people having the same problem with their 8525's

good point... i can say that i have had signal issues with both 1.16 and 1.20 radio but not to the extent that you are having, and the new sim solved alot of issues for me in the beginning.. Now i dont have any issues when in a GSM area, only seem to have issues in a 3G area

ok got the new SIM Card, but the problem persists. hardware?

I've had the Cingular 8525 for a week and it has one of the newer 64MB SIM cards (same that the Sierra AirCard 860 uses and required for 3G network access). I haven't had any call dropping problems at all. If it persists I'd get a replacement ASAP.
Music Man

got myself a brand new 8525 from my local cingular store at the end of last week, and the problem persists. i also have one of the new flaming 3G SIM cards. the only thing i can think of now is the network in my area. any other thoughts/ideas?

did you have this problem prior to the 8525? also go to start>settings>system, then tick device information and tell me what radio version you have

did not have this problem prior to getting the 8525. had a tytn for a few weeks and didn't experience this (although it did have the screen alignment problem which is why i had to get rid of it). i have had the problem with both 8525's. my radio version is 1.16.00.00

Can't add much to the discussion...but I have an SPV M31000 (Orange Tytn Flavor) And ahve the same issue when in an area which switches between UTMS and EDGE. It also appears it will sometimes lock a call.

I can't add too much either. I've got an 8525, and I do experience the issue at my company's current office (thankfully not the one I actually work out of though, as I'm at a client site and rarely at the home office). I find my issue seems to be specifically with being on a fringe area of UMTS/GPRS. GPRS is a much stronger signal that the UMTS, so I see it swapping frequently. Sometimes it drops completely. Weird thing is though that it doesn't happen all the time..

sounds pretty much like what is happening to me. the annoying part is that it doesn't pick up the signal automatically again once i'm out of that fringe area. if that was the case i could live with it, but i miss calls all the time because of this.

HTC TyTn Cingular 8525 Sim and other issues
I have an HTC TyTn since October 12, 2006, and have had a great deal of problems, but none in Japan while traveling, only in the US. Cingular is constatntly changing and upgrading its services, its servers and its policies. My SIM which worked until 12/26//06 never allowed a SMS message through since then? It seems now to be caused by the fact that I have the old SIM, but was never a problem till Cingular upgraded its towers?
The Phone portion will not work well in the UMTS mode, and the techs say that it is because the towers are not all turned on as yet in my area. If you try and have the Outlook and lets say AOL turned on to download, when the phone is in GPRS mode, your calls are blocked when the AOL goes out to check for mesages. The techs say it is not the same on UMTS. The UMTS uses more battery, but especially if the phone is looking for messages often to other than Outlook. Of course the programs never close, even IE, unless you shut them down manually in settings/system/memory/running programs.

Unable to make or receive calls

I wonder if anyone can help with a fault on my M3100. So far I've searched this website for answers with no luck. I have Hard Reset the phone, upgraded the Radio, all without any luck.
About 6 days ago my M3100 suddenly stopped being able to make or receive calls. Whenever I try to dial out the call drops out before being established, and if I try to call in to the phone the caller receives a series of beeps.
At first it seems to be a SIM problem, but the Vodaphone SIM is fine in any other phone. If I put my Orange SIM in the phone it just comes up as "No Service".
I'm at the end of the line in what to do and it doesn't seems to make any sense.
Any comments, suggestions, advice or help very much appreciated.
..... Further symptom details:
I can send and receive text message with my Vodaphone SIM installed and access WiFi and GPRS networks. Orange SIM won't connect at all! Both SIMS work fine in a standard phone ! Only clue I can think of here is that the Vodaphone SIM is UMPTS and GSM where the Orange is GSM only. The spare phone I tested them in was GSM only.
Could the GSM part of the M3100 be stuffed ?
I'm stumped for the time being!! It doesn't seem to make any logical sense. Maybe any of you who know the in's and out's of how the device communicates might find some clues in that...
Heeeeelp !

More details..
I've just added a few more details on the symtoms.. maybe the few extra clues might yeild some thoughts from someone !

Have you checked the band selection in Settings > Phone?
Is it possible that the phone could have become blacklisted? How long have you had it? How did you buy it? (This is probably NOT it, since the text still works.)
Have you tried a tweaker to enable HSPDA?

Had the phone for over 12 months so Blacklisted shouldn't be the issue. I've tried all the band selections including Auto but no luck.
Haven't tried the Tweaker... do you have any details on that...
Up until it suddenly stopped working it worked on all networks..
Another possible clue is that I was "Roaming" in France for a month and it was there that I made my last successful call. I have UK SIMS... I have an Australian SIM which I'll try now to see if that makes any difference..

Tried an Australian SIM roaming in the UK ! The service connects on two available networks,Vodaphone and TMobile but not on Orange and O2 (like with the Orange UK SIM). Same fault as the before with the networks it will connect to.
This seems to eliminate the SIM or Network being the fault and isolate the fault to the Device...

probably not the issues, but worth a try?
I live in a very strong 3G + HSPDA ares, but cant make or recieve anycalls tho texts work on T-mobile, i need to have my phone in 2G mode, and calls work fine???
If i leave my house and go a few miles 3G works as it should able to call and recieve etc!

Can't seem to work out how to force the phone onto 2G or 3G ... if anyone can advise I'll give that a try!

I have had very similar problems to this.
Please see my post:
http://forum.xda-developers.com/showthread.php?t=325149
I do think this is some sort of network problem as after I posted the issues in the thread above, I left home and travelled about 6 miles and the signal came back and the phone worked fine.
Today, I have been able to make and receice calls but all of a sudden I got cut off from a call then could not make or receive calls (incoming goes straight to voicemail).
I can however use my Orange SIM without problem and both Vodafone and Orange SIMs work fine in other phones.

You can also go into Settings > Phone > Band.
If the band tab does not appear (to the right of the network tab), then you may need to do a registry tweak.
From the very helpful wiki:
Enable/Disable GSM/UMTS Band Selection
Cingular kindly disables anything useful about the network on the 8525. To enable the Band Selection Tab on your Phone settings page, set the following:
[\HKLM\Software\OEM\PhoneSetting\]
"ShowUMTSBandPage"=dword:00000001
To disable, simply clear the value to 0:
[\HKLM\Software\OEM\PhoneSetting\]
"ShowUMTSBandPage"=dword:00000000

Have travelled outside England again this week and... well the phone works fine roaming on my UK Vodaphone SIM. Seems very ODD.. only thing I can put any logic to is a problem with the GSM part of the phone. It's working here in Stockholm on the 3G network no problem.
Anyone advise how I force the phone to be on GSM and 3G so I can test this theory. The BAND settings under SETTINGS>PHONE don't seem to give you this control over how it connects..

Hey i got the same problem anyone solved it yet!

Hi Sunnyb1
Since my last post I returned to England where the phone was useless. No SIM cards would work, some would not register at all but my Vodaphone SIM seemed to register but as before it would not receive calls, nor could I make calls out.
Now I'm in Australia with an Australian SIM card. NO PROBLEMS AT ALL !!
The phone works just fine !!
It's a mystery indeed...
Without any knowledge of the ins & Outs of how a SIM card / Network / and the phone work together it's impossible for me to arrive at any conclusive logic.
Hopefully someone might stand up to the plate and offer some explanation !
Anyone from HTC out there ??????

I got the phone and it was working perfectly on Orange then i tried unlocking it and ever since it has come up with "NO Service" like you everytime i put a Orange Sim in the phone it does not show up.. but when i put a Vodafone sim it works perfectly i tried reflashing the radio's many times

I unlocked this particular phone 6months before this problem showed up so I don't think the Unlock on it's own is the cause. What's particularly baffling is that a SIM may not work with the phone in one country.. but in another it works fine.

..... another country that is !

Hey Steve i have found out what the problem is after hours of research
I found this of another website
Orange & O2:
If you place an active orange or
O2 sim into a blacklisted handset you
phone will not show any signal strength
at all! If the handset is a Nokia then a
"SIM card registration failed" message
will also be displayed. If your handset is an
Ericsson then an "Invalid Mobile" message
will be displayed. For most other manufacturers
the handset will simply show no signal!
Vodafone & T-Mobile
If you place an active Vodafone or T-Mobile sim into a blacklisted handset, the phone will appear to function perfectly UNTIL you try to make an outgoing call. When you try to call out from the handset you will hear a sequence of beeps and then the call will be dropped!!
........
This means the handset you got is stolen or someone has blacklisted it ... i got mine of EBAY! and reading that i figured that it is stolen
It wont work in the UK but it will work everywhere else in the world

Mmmm... that's interesting Sunnyb1. If my phone is blacklisted then happened in JULY this year which was 8 months after I bought the phone. I bought the phone legit .
Can anyone advise what the "Blacklisting" process is.. I assume its done by using the IMEI number.
Who is the rightful owner of a handset and can any phone be blacklisted by anyone, and possibly by mistake ?
Would unlocking the phone from Orange cause a phone to be blacklisted ??
How can you "Un-blacklist" a phone.

Answered my own question here......
This website seems to have the answers
http://www.unlockme.co.uk/blacklist.html

OK... still on this thread. Can anyone advise how you find out which network in the UK has blocked your an IMEI number. I gather any of the UK networks can block any IMEI and it's not unknown for errors to be made. But only the network that blocks the IMEI can Unblock it.
Thought I'd post this before waiting forever for some call centre dimwit to give me the runaround.
Thanks...

HTC P3450 Network Connection Problem

I am having a problem with my HTC Touch P3450 phone for the past 2 weeks. Although the GSM signal looks good, I am not able to make/receive calls. I am on "Phone" mode (not Flight Mode or similar). Everything else (WiFi, programs etc.) works fine.
My operator is Turkcell and I live in Istanbul, Turkey. The phone was purchased from the United States.
I have done a ROM update to ROM version 1.17.707.2B WWE but the problem still exists.
Has anyone else experienced this kind of problem? I suspect that this issue has something to do with the 3G upgrading process going on in Turkey.

Can you try to use your friend's sim card and see whether it works.
Is it something like a dropped call?

I tried two different SIM cards, one with my operator and one with another operator. I am still having the same problem.
The problem is that I cannot make any calls at all, rather than dropped calls.
Also I cannot take any calls, when I call myself from another phone it goes to voice mail as if the phone is turned off.
I guess it is a hardware problem then.

I think its time to change your phone's radio. go to the elf-upgrading section to find out more.

I have the same problem
Hi, i have the same problem. When I make a soft-reset on my Elfin it has signal, but just 3 or more minutes after i cloud not make any calls and if someone try to call me they receive the message that my cellphone is off. Rigth now i am performing a radio upgrade and i will let you know if this is the solution for the problem, if you are done with this please let me know how to solve this.

Hi I have the same problem with this phone, can some one of you tell me witch is Radio ROM is the best for HTC ELF.
Thank you guys

I think that this is a common problem on Htc Touch, cause i have exactly the same problem.

I have this problem too
I upgraded new radio 3.34.90 but the problem still make me angry

Same problem.

i have same problem sometimes network gone automatically but signal shows full but after reset it starts perfect. thn after somtime same prob?
is thr any solution?

same problem here (P-3452 Elfin)

bsnl sim not working
Hello there.....
I am from Bangalore,India. i was using BSNL SIM for 2years. suddenly one day the Sim was dead. i thought sim problem so replaced 2 times after that got AIRTEL Sim. now its working fine. the problem is with 2 or 3 carrier operators. STRANGE!!!!!!!!

i have this problem too nobody to help pelease
tanx

please some one help me.....

I have been investigating this issue on and off for a few months now on one of my elf’s. I originally bought this phone off eBay to test stuff, and found no signal was being received when I got it. The auction did say this so fine. Checkmend says it is not blocked in any country, and is not stolen etc. Therefore, it is definitely something on the phone opposed to networks.
The phone can pick up signal, it noes networks exists, and can identify them, however, when registered and "connected" it does not pick up messages, and when I try to make a phone call the signal completely drops.
I like others have tried many roms. I have even tried every signal radio. I have also tried 6 different working Sims across a number of operators.
Basically, I think this issue is hardware, I mean, there really isn't anything else that I can think off. I have done some reading, and I *think* it may be down to the PA chips. There are 2 off these in the phone, one for Radio signal, and the other for Bluetooth, and wifi. (I think that is it).
These are located just above the battery on the back of the circuit board from what I can see, protected by 2 parts. One removable (two top screws - also contains the speaker) and one fixed into the middle part of the body.
I've done some playing, and it seems may be easy to break, either by dropping the phone, or even possibly by something as little as keeping the phone in a pocket and sitting on it.
I am not sure where I can go from here. I may need to investigate this further, but it is looking like it is going to be a dead end, considering I am not able to BGA solder to replace it, and expect the cost in doing so outweighs buying a new phone. I'm going to look into signal amplifiers, and see if I can find one that’s not just a piece of tin foil, and actually works. It will be interesting to see if that will improve the signal far enough for the phone to be usable once again. I may even just try with some kitchen foil, or by plugging in an external aerial (which I do not have yet, and may be costly, and therefore no point). If the external aerial works, I guess the chip could only be damaged, and not able to get enough strength itself.
This is only a theory on what I think is wrong with my Phone, and may be different to what everyone else’s is. But i thought I should put it out, to see if anyone else is able to confirm/kill my idea. It is a theory after all, they are made to be proven!
If anyone else has any ideas, feel free to pitch them, I like hearing what others are thinking, and it may be possible, although I admit very unlikely, that we could find a resolution to this issue!
Stu

@ashkan62 , can you provide a detailed problem please, this may give me something more to look at that I have missed.

wow. that's really informative. I've done upgrading radio roms too and even the spl. but nothing happened. hope your investigation on this works. thanks for the info.

or how about upgrading the o.s.? did someone tried that? coz I'm planning to upgrade my elf wm6.1 to wm6.5 and onyx 4 to onyx 6. would that work? what do you think?

[Q] no network coverage after installing wp7 on my hd2

just installed wp7 on my hd2 and after the start up my phone keeps searching for the network. have tried automatic network selection and tap to select but no luck. am using 2.15 radio. would appreciate any help.

goto your settings, scroll to cellular, then down to add apn, in the apn box type epc.tmobile.com and leave the rest blank.
this works with tmobile us

isn't that supposed to be only for the data connection? even without entering the apn the phone should be able to find the network for just making voice calls. so mine seems to be a different problem. the phone is simply unable to catch any signals.

from my understanding of the whole cell phone fiasco is the sim card has everything the phone needs to connect your providers tower and also tells your phone what services you have voice, data, etc etc, so it should setup voice automatically. i would try searching for the program (htc connection setup) they use to install the xml files it also sets your phone with the provider.
good luck.

Only search at the internet for your apn settings, enter them and voila you can use your data connection, nothing more nothing less and done in a minute. HTC Connection Setup don't work well but you have to use it later if you want to change phone type to HD7 for the Marketplace ^^)

yeah we covered that part, the concern is that the phone is/was not connecting to the towers

Maybe check out other Radio ROM. 2.15 should work well, but uses more battery.

switched back to winmo 6.5 for a while and the same radio worked fine (caught the signal etc.). Just now again tried to flash wp7 using 2 different radios, that is 2.12 and 2.14. Have already tried 2.15 with my first attempt, but the problem just remains the same.... 'no network found'. any thoughts? have even tried putting in the apn too. no luck

u know its funny cus its the exact same with mine exactley the same ive tried everything and it picks up the signals but it wont let me connect to any network at all... the phone is just fine except that one problem.. plz any body help us with this stupid problem

After trying different radios by flashing and re-flashing, I've noticed something I should mention. My phone dialer shows a sim icon with a lock on the top left of the screen. Does that shed a new light on things?

sim lock ???
hey sameer... I have the very same issue with my HTC HD2. It is unlocked and I am facing the very same issue that you are when I revert to WinMo 6.5 everything works fine with the same radio. I've tried almost every radio now and have no luck. However, the funny thing is that I do see the sim with a lock when I go to my dialer. I suspect the OS is SIM Locked, however, when in WinMo 6.5 every Sim Card is recognized and works properly
Any luck with the issue yet??
Let me know of your thoughts... btw I'm on Ufone's Network.

It's the sim card!
Problem solved for me and hopefully for salmanjavaid too!
I learnt it the harder way though, by which I mean that I spent money to buy an HD7 and after inserting my sim in my brand new HD7..... no signal again! oooops! Only then it occurred to me to try some other sim cards. My network is also Ufone here in Pakistan. So first I tried a Prepaid Ufone sim (the one with white and orange colour and 64K printed on the back)...and Lo and Behold my hd7 gets the signal and network settings and data connection works fine too! Other operators' sim cards like Telenor, Warid and Mobilink worked fine too. But when I insert the sim card which is in my use back again....no signals again! This sim card is a different version, perhaps not 64K and plain black color on the back.
A call to my Personal Customer Service Executive assigned by Ufone sets the next course of action. He'll bring a replacement sim card for me, when I get back home.
My suggestion to salmanjavaid: try other sim cards first. If they work then get a replacement sim card.
Hope it solves your problem too.

id give this a shot. I'm on vacations in Pakistan and have my Sim Card from O2. I will give it a shot tonight Thanks for the suggestion.
