"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 !

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.
seen from :http://vip.asus.com/forum/view.aspx?id=20070818011855796&board_id=6&model=P535&page=1&SLanguage=en-us
Thanks.

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.

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.

Please help!!! 8125 does not function as phone

Hi I own a Cingular 8125 (Wizard), yesterday I did a soft reset because the phone was too slow (it wasn't turned off for about 4 weeks without restarting). When it launched it ask for my phone pasword, then for my sim PIN and took them without problems but it launched without connecting to my provider signal. Everything on the phone is working fine (WiFi-Bluetooth-PC Sync, etc...) but it keeps searching for signal.
I tried 3 different sim cards and the result was the same, then I test my sim on a friends phone and it worked fine.
The only thing I did to the phone a few weeks ago was try to use a dual sim ghost that didn't worked (it show the dual sim menu and worked fine with line 1 but when I tried to switch to line 2 it happenned just the same that is happenning now with just my sim inside, it kept looking for signal)
I did a complete reset and nothing.. happened the same, then I upgrade it's ROM to the one cingular has on it's website (http://www.america.htc.com/support/8125/software-downloads.html) it was the same one installed but it did the upgrade process anyway and NOTHING!!!
Does anyone have an idea of what could be happenning and what can I do to fix it?? I don't want to have a PDA phone just as a PDA and not phone. THanks.

No service message

Sorry if this has been posted before, couldnt find any threads on the subject, I have a unlocked Touch HD but when i insert a o2 sim card it keeps showing as no service. when sim card is inserted it does recognise that its a o2 sim card and configures the setting
anyone out there had same issue?

Stock or cooked rom? Has it worked before or is this new behavior?

Cooked rom, o2 sim didnt work before i installed cooked rom

Do you know anyone else with a sim card that you can drop in there to see if theirs' get service? How old is your sim card? May take it by your provider and have them stick a card in to see if they can get it to fire up.
Also, go to your phone settings and see if your connection is set to a specific frequeuncy or if it's set to auto. If it's set to a specific frequency eg. GSM 1900/2100 or something like that, change it to auto and see what happens.
Did you purchase the phone unlocked or did you do it yourself? May be matter of flashing the correct radio.

Ive tried what you have suggested but still same issue, ive upgraded htc hd to the latest radio but same issue.

MIA,
Have you tried the latest stock ROM (do a hard reset after reverting to a stock ROM)?
Have you tried different SIM cards from different networks?
How did you acquire this phone again?
Cheers.

I swapped my htc tytn 2 for this phone, ive tried orange, t-mobile, vodafone sim cards and they are all working fine, when i got the phone it had the latest official rom from htc and even then it was still showing as no service, ive upgraded rom to duttys 6.5 and upgraded to latest radio.

So you have tried other sims with this phone and you get service? If that is the case, I'm inclined to believe it's your sim. I've seen posts from others where their sim worked perfectly in their TYTN, but once in the HD, it didn't. Something to investigate.

Ive tried my friends o2 sim cards and same problem no service message, im starting to regret getting the htc touch hd as i really wanted it in the o2 network.

MIA,
Have you tried it in GSM mode? It's really impossible that you can't get even the most basic of things running (excluding things like 3G or HSPDA).
Don't give up, just keep tinkering around in the phone settings.
Cheers.

Ive tried everything that has been suggested. this phone is driving me

MIA,
I'm really sorry, but I have no idea why it isn't working. The only thing I can tell you is to go into an O2 store and keep asking to try different SIMs and explain your issue. I simply cannot imagine why a sim would not work on one GSM network but it does for others.
That just baffles me.
Cheers.

ive tried brand new o2 sim card in the phone and same issue again, it recognises the sim card and configures settings but still same problem with no service on the reception bar its just got a ! mark next to it.

Signal stop working! :(

I woke up this morning and the signal was good and strong. Then at 10 am there was no signal on the phone. Tried to get a signal outside and no luck. I called T-mobile but they don't really know what is going on. I tried flashing another radio to see if it was the radio and still same problem. Hmmm what could be the problem I am in New York. Any one else experiencing a signal problem? Or if anyone had this problem before and fixed it. Any help is appreciated.

You aren't getting anything? No 3G, Edge or just regular?

Nothing no 3G no Edge nor phone works its stays on searching

hard reset doesn't work either?

Nope ^^ tried removing battery, hard reset, changing radios, and manually choosing carrier... I will try the sim card in another phone to see if its the phone

Call tech support back they told my brother they have had several of these calls but no one called them back after they told them to go change their sim card.
We tried the SIM card in another phone and same thing-no signal. So he went to T-mobile store and was issued a new SIM. Still no signal. In my brother's case it has to be an account problem so your best bet is to start there. Maybe try a SIM from another account, even one from ATT should work.

Got it working Thank you all for the advice. Apparently it was a sim card problem. I got a new sim card and I am up and running ^^
