Very strange GSM problem - JASJAR, XDA Exec, MDA Pro General

Using O2 Exec.
Device working perfect like PDA with GPRS & SMS functions but then I try to call it's loss signal. After "call ending" it's fidn signal again.
Already undergo to install diferent versions of ROMs & RADIO. Try to unlock to make sure that phon not locked.
Somebody HELP!!!
PS. Then SIM installed & I turn flymode I can't off it but then SIM is not installed switching performing without any problems.
PSS. sorry for english

Have you tried ...:
a) a SIM by the same provider
b) another provider's SIM
Make sure that your SIM also works in another phone. It may be unlikely that your current SIM could be the problem.

I have also a strange problem when i send an SMS larger than 300 characters it spends me money but it doesnt send it !

SIM from another cell operator, but it's of course working.

Then it might be a good idea to have your SIM replaced.

Tested three SIMs from different operators? the result same :-(
All SIMs work on another phones.

Have you tried reinstalling the ROM that worked in the 1st place? Otherwise you'll have to consider taking to a shop.

Signal Loss Problems
I am having the same problems. I even had T-Mob send me a new phone with the same result. Did you ever find a solution?

I am also having same problem, the agency informed me that there is a damage in the internal board and it cannot be fixed. this is rediculous...

bull****!
i sent my pda for repairs (to fix a different problem) and after two weeks they came up with the same answer,
but a day after i got my pda back, i changed batteries and found out it was a battery problem, and not a board problem!
thats a few hundred bucks of differens!
they seem to find it as a "default" answer, instead of saying "we don't have a clue what the hell's wrong".

"Unknown SIM Error" on MDA Pro on T-Mobile

Hi,
I just bought an MDA Pro direct from T-Mobile's website and it was delivered today. Unfortunately, while the PDA side of things works perfectly, it won't connect to T-Mobile at all.
On the 'T-Mobile' start up screen it displays the text 'No GSM' above what I think must be version information.
It reports 'no service' in the phone status bubble, and SIM Manager says: "Only emergency service calls can be made without a PIN" When I enter the PIN I was given, nothing happens. I think it goes into 'change PIN mode' because then I can put two more 4-digit numbers in (it doesn't matter which!) and then it says "Unknown PIN Status. Unknown PIN Error"
Unfortunately it isn't just a SIM problem as the SIM works in my O2 P800.
I've spoken with T-Mobile and they want to swap the handset, which would be fine if they had any in stock! I'm wondering if anyone here had any advice on ways I could try fixing this short of waiting for them to get in touch and tell me they have another handset I can try.
Any suggestions would be much appreciated!
Hi,
what is your local provider ? Is it T-Mobile, Vodafone, E-plus or O2 ?
The mda pro only works with a t-mobile sim !
- Superbowl
Try to clean the sim before putting it back in the MDA Pro,
Generally works for me!
i had the same problem with my jasjar here is Australia......my sim works on any other pda and phones but not the jasjar.....apparently the sim that i have or some of the new sims have a little higher voltage than normal.......and the jasjar dont like it.....so what i did was replace the sim with another one and that worked......al they had to do was port my number to the new sim......but before it did that tried to put the sim in first and it started to look for a network so i knew this was gonna work......becoz before when i put my old sim in it just says invalid sim or no sim........so try replacing ur sim with another one......perhaps try and get an old sim maybe the sim has some in stock.....i bet ya that will wrok....good luck
Thanks guys ... I'm trying to find an older T-Mobile SIM to try. It's just frustrating! I've tried giving the SIM a wipe, to no avail. If it is that the SIM is slightly incompatible, T-Mobile sending out another unit won't really help, right?
How annoying!
If anyone else has any great ideas I'd love to hear them!
try using someone elses sim and put it in the device and give it a try to check if its definitely the unit and not the sim......when i rang the tech support for optus thats what i was advised.....and they were right....sim voltage was the problem......anyways try getting another sim.
Contact customer services.
The problem sounds like you SIM is too old.
They should ask for your SIM serial number, if its too old they'll offer to send you a new SIM or something else to make it work straight away??? :wink:
The MDA PRO as its a 3G type phone with WCDMA it needs a diffrent sim card that is usaly known as a 3V USIM.
Its the same on Three in the UK, the sims from their phones will only work in 3G phones not standard GSM ones and vica-versa.
Old SIMs (from about 5 years ago) are rated at 5 volts. Newer ones are 3 volts (not just for 3G). Trust me, I work for a certain mobile phone company who sponser West Brom. ;-)
The problem will be fixed in a future software upgrade. But for now you need a new SIM or your phone unlocked.
Trouble is, this *is* a new SIM... I'm moving back to the 'hardware fault' diagnosis I think.
I went to a friendly carphone warehouse shop in Oxford and tried a new (and definately working) T-Mobile PAYG SIM and that gave exactly the same error.
Maybe T-Mobile need to send me a 3G SIM. I guess I'm probably just going to have to wait until they can send me a new handset to see what happens.
Ho hum!
There's no such thing as a 3G SIM. The 3G gigery pokery happens on the phone. There is no need for a different SIM. The MDA Pro has a problem with SIMs with certain serial numbers (Don't know which coz I'm not at work). You need either a SIM that the phone likes or your phone unlocked. Call customer services if you still have your phone.
Had the same problem allready twice in 2 weeks.
One time a soft reset made the device working again - another time I had to take out the sim card and put it in again, then it worked. But all email accounts were gone and had to be installed again.

Hi, thanks for that reply... it seems very useful! If you could post/pm me the numbers of those SIMs that the MDA Pro is unlikely to like I'd really appreciate it... customer services aren't striking me as very helpful (and certainly not knowledgable) and I can tell that if I call them they're still going to say: Wait until we have another handset in stock and we'll see what happens then. Which doesn't help me much as who knows when that will be?
Thanks!
Any SIM serial not starting with 06 or 07 will be affected by the issue.
eg 90043575, the serial starts with 04.
This will be fixed with a software upgrade in the future, in the mean time you either need new SIM or you handset unlocked. For either call customer services.
I got my MDA Pro a few days ago also, had the same problem as you, basically the handset is network locked, not sure how they managed to lock all UK network, basically give Tmob a call and make sure your stay on the line until they provide with an unlock code, i got mine, now my old sim works and my handset is unlocked

i had the same problem with my ASUS P535 (here is France) with new SIM card.

I had the same problem BUT-
I had the same problem but i had been using the sim card successfully with the exec for a year, after a hard reset it doesnt recognise the sim. will a ROM upgrade fix it or is it a hardware failiure?

I had this happening to me just last week with a card that works all the time. Then followed that I had no sound coming off speakers or bluetooth. In my case it was a third party software problem. Don't ask me which as I install and uninstall too many applications and my Uni gets in a tangle sometimes. A soft reset instantly (in terms!) restored phone activities and sound, so I recommend a reset if you haven't tried it already. Maybe you will need more than one.

Phone cut off problem! Have tried everything i can think of

Hi Everyone
Got a Wizard (badged as an O2 XDA MINI-S) about 4 weeks ago but having nothing but problems with the phone functionality.
The problem:
The phone will loose connection to the O2 network. I could be in the middle of a phone conversation for 3 mins or so and it will act like it has lost reception. I look at the screen - it shows the call still connected and the signal strength shows full. Then the screen will say disconnected and the signal strength will drop to nothing yet the GPRS indicator will still be there. I either have to reset the phone or switch the phone to flight mode and back out of flight mode! This problem occurs if i make calls or recieve them.
I bought the phone on the standard ROM from O2 then upgraded it to the ROM version 2.21.4.101 which gave me the push functionality AUTD. I didn't use the phone long enough to tell if this problem occured after the ROM update.
Thanks to Faria and Machinagod's postings on here i was able to CID unlock the wizard to try a different ROM to see if that cured the problem. So i put the IMATE K-JAM ROM version 2.16.9.1 on yesterday, didn't add anything else on it, still the same problem!!
Any ideas anyone? i'm pulling my hair out now!! :evil:
First i would try cleaning the sim contacts, both on the sim and device. Sometimes faulty contacts lead to this problem. (poss faulty sim - have you another sim you can try?)
Next i would contact o2 to check there is no fault at their end e.g. faulty transmitter, computer systems.
If none of these solve the problem then its prob a faulty radio on your device and i would exchange for a new one.

Do you have a SD card inserted ?
If so remove it for the day and see if the problems persist.
Thanks for the suggestions guys.
The SIM card works fine in other phones (i've not had this one for long!) so i hope thats not the problem but i'll give it a shot. I'll try getting rid of all the contacts etc on the sim and phone and see what that does.
SD card - yes i have one inserted now but the problem was still happening when i didn't have one in there.
Any other suggestions?
Thanks for your help so far

heheh i think he means the actual contacts on the SIM! you know the metal bit of the SIM that makes contacts with the pins inside the phone!
not your phone book contacts!
HAHAHA LOL Stupid me!!!

right - that didn't work anyone else have any ideas what could be causing this?

I am having the exactly same problem.
I am going to request a new SIM card from O2 as I think it is due to the SIM. Will let you know my result.

Exchange your phone - maybe a faulty radio in your phone. You could try a new sim but as you said you've tried it in other phones and they are ok.
Darklondon - thanks very much i'd appreciate the feedback!
Meschle - i've got to say i think i agree the phone has a problem! i just hope that if darklondon manages to resolve his issue with a sim card mine will work with the same resolve.
I also have this problem. Im on the T-Mobile network in the netherlands. When it cuts off you can see that there is no more radio contact (there is a cross on top). It then resets the radio and gets back. Within 10 seconds of the cut off i can be called and call back????
it's been a month since my last reply and I havenot yet change my SIM yet :shock:
however, i think i found the problem, at least, i think so.
the constantly cut off issue, for me, it's due to the overclocking. initially i overclocked my CPU to 264, which brought the instability to kill the "phone" program constantly. if you have any task manager try to kill a "phone" program, and you will see the signal bar goes off completely.
so, i changed my overclocking to 242. problem solved, no more cut off now.
wow really?! but i'm not overclocking .... mayube i should! i don't see the phone program in task manager?
I can see the "phone" program or say thread with SmallMenuPlus and vBar. And sometimes I can see more than one.
hm, I don't see a "phone" process with Memaid, but I'll try the reducing of overclocking too, since I have the same problem. 240 is the nearest option to 242 though in my omapclock...
Lars
I've found that this problem occurs using many of the AKU2 ROMS out there along with an application that requests a GPRS connection on a very frequent basis (GoodLink for me, MSFP, Agile Messenger for others).
The problem is that the application requests a GPRS connection, and for some reason the device decides to drop the call in order to connect.
For myself, this started happening after upgrading from a 2.17 summiter ROM, and continues regardless of what ROM post 2.17 I use. I've also tried flashing many different Radio ROMS, all to no effect.
I've been back to 1.8, and that's solved the problem. I'm now using a 2.17 ROM that I flashed today to see if the problem persists there.
This isn't an overclocking problem - as I never overclock.
I have a AKU2 ROM installed, though I never use GPRS (way too expensive here). So that can't really be it I guess...

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?
Matt
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.

SSSOOO depressed !!! My Exec phone doesnt work anymore :(

Guys,
I am SSOO depressed.
I moved to Turkey for a few months and the the same SIM that I previously used which is local turkish displays NO SERVICE. Even the Orange sim that I have used with my exec in my country AND in this country in my last trip isn't working anymore. I also have my old PDA2K with me here that is working perfectly with all SIMs. It's just that my Exec doesn't work anymore, so it's 100% gotta be an hardware problem.
when I click to search for networks I get the 3 turkish networks. however when i select my sim network or any other for that matter, nothing works. it just gets NO SIGNAL.
I tried to hard reset the device in hope that some program may have causd the problem but that didn't work as well. Even bare setup leaves the phone with no signal.
I may be wrong here, but I think my theory makes sense. I think that the internal Antenna is disconnected or isn't functionning, hence why it succeed to read the very mute GSM providers list but is unable to transmit a signal strong enough to communicate with them.
My O2 exec was bought by a guy who sold it to me from the UK. O2 will never service this machine since i didn't purchase it from them as well as I already flashed my rom and running JJ rom ever since I own the machine which is back 5 months ago.
Needless to say if you peole are like me you will understand my feeling. I feel like an inpotent without the phone and do not like to purchase a cellular phone and go backwards in technology.
If someone can enlighten me on how I may try to fix the machine myself or otherwise someone can fix it for me that would be so great.
In hope for help,
Tommy
Man that sucks, I feel your situation. I would be upset w/o my Universal as well. Here's a link to the service manual:
ftp://xda:[email protected]/Universal/UNniversalL_Service_Manual_CONFIDENTIAL.pdf
Maybe you could try disassembling it to check the attennas for contact? To get to the attennas doesn't seem that hard.
Re: SSSOOO depressed !!! My Exec phone doesnt work anymore :
Did you register the IMEI with your Telco?

Your antenna should not be the problem as you can see the list of operatots on your Exec.
To be shure it is the hardware problem try to do this:
1. Remove SIM card
2. Try to make an emergency call (not sure how :? )
If you succeed in doing the emergency call - this appears to be a network barring problem that mentioned above in this thread.
thank you all for replying to my post !!! this is appreciated.
it seems the mistery was solved, when i talked with a turkish friend before reading your replies. Well the mistry wasn't solved, but i know what it is.
STRANGE country. The Turkish Telecom blocks some machines (IMEI) that you bring from overseas !!!
It's like a gestapo. Truely amazing unbelievable thing.
You see, the Turkish government instructs to block all IMEI that were not purchased in Turkey and use a Turkish sim card. The result is that if you bring you own mobile phone from anywhere in the world into Turkey and try to insert a Turkish sim card into it, the turkish goverment will block your machine! you can't even use your origin country SIM anymore after they do that!!
They Lock the IMEI so that you cannot use it with any cellular provider! Why? Because they assume you're Turkish and brought a phone without paying taxes in turkey. Would you ****in believe it?
I also carry a PDA2K and this one still works with a Turkish SIM, but I guess it may be blocked as well soon. People I talked with told me they have heard of this rule but have never seen anyone get hurt from it by getting his phone blocked.
So if you're a turist and thinks about using a Turkish prepaid SIM or any kind of SIM, think twice. within days, weeks or months, your phone will be useless here. My Turkish SIM card worked fine last visit a month ago, but it doesn't anymore.
Now if I would ask how I could change the IMEI that would be considered illegal because many want to do so because they are thieves, but legitimate people who got their phone blocked by a obscene Turkish laws has nothing they could do about it, even if they aren't Turkisj.
My friends talked with the Turkcell for 30 minutes and there was nothing they could do, they said it's a state issue and that only within a week time it will be in their hands so i would be able to go to their service center and show my passport. What a country!

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.

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!

@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?

I think it can't harm to try, be sure to follow the right procedure.
Yeah. I'll try to do the upgrade this week. I'll inform you if anything happens. (like bricking my phone. )
