"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.

NO SERVICE? - For no reason

Hello..
I last night put my phone onto "flight mode" so that i was not distrubed in the night if a text came through....
this morning i set it back to normal but the network reception reported NO SERVICE
when it had not come back this evening.... i put my sim in a different phone and used a different network's sim card in my pda.... NO SERVICE was reported for this as well but the sim that was placed in the other phone registered on o2 as soon as the phone was switched on
I've only just bought my MDA but off ebay... although it was new i am unable to contact the seller... please can anybody help??
email me to [email protected] or [email protected] if anybody can help
Thanks

MORE info re above
Hi again
In my frustration I have swapped sims again and this time put VODAFONE pay as you go sim in the MDA Magician above.... It found the network and i was able to ring/text from it.....
On putting the O2 Sim Back into the MDA it said NO SERVICE again.....
But using that very same sim in my nokia finds a network.....
The MDA is originally a TMOBILE one that has been unlocked...
ANY help on this would be very appreciated as I'm very annoyed that it's stopped working.
Thank you

Soft reset?
Although, I think taking your batter out and swapping sims may count as a soft reset.

Thanks for the reply - but again that did not solve it... besides to eliminate this i did a HARD RESET as well and re configured it....
I've even RE UNLOCKED it in case this was the problem
(its a T MOBILE PDA) with an O2 SIM IN...... I bought it in November time and unlocked it the same time... My O2 Sim has been working ok in it until the other night when i decided to put it in "flight mode"(so i wasn't disturbed at night)
Im suspecting that it anything to do with IMEI number vs SIM CARD number? Could this have been blocked somehow to that phone?
Its very confusing as it WORKS with VODA sim and DOESNT with O2 yet the SAME O2 sim works in my old nokia 6610.... aaarggghhhh!! LOL

If your MDA works with a Vodafone SIM, it certainly can't be blacklisted for all UK networks since it picks up Vodafone. Secondly, it sounds more like a SIM card issue relating strictly to the MDA. What happens when you try another O2 SIM card in the same MDA?
Make sure the O2 SIM hasn't been damaged in some way, if all fails you might want to take the MDA to T-Mobile to see if they can determine whether its IMEI has been blacklisted for certain networks. Otherwise a ROM upgrade may also help fix the problem.
Good Luck

My guess is that your magician is reported & listed as stolen. Probably not all providers are using the same list with blocked IMEI numbers. Which can explain that one sim works & the other doesn't though works in an other phone.
See if you can find a list for your country on the web. There are some references to such lists in this forum.

check which band your phone is using....
go Phone>Options>band> then select auto

Invalid or Missing SIM Error

I have been running my Wizard fine for about two weeks on a Vodafone SIM. The phone is o2 supplied, but I have CID & SIM unlocked it and sucsessfully updated the ROM to the Tmobile 2.26 base and Faria's WM6 on top.
However, after resets recently, the handset refuses to accept my SIM card, and either report that the SIM is invlaid, or is missing completely.
Turning radio on and off sometimes picks it back up and it is fine until a reset. However, I now seem unable to get the radio back at all
I would really appreciate help on this one, as I am lost without my phone!
Many thanks

sounds like a bad sim, speak to your mobile operator, they should send you a replacement.

SIM is work supplied unfortunately.....tried to persuade the boss to get it changed, but he tried it in his Nokia 9500 and it worked ok, so no joy
How easy/cheap are SIM's to clone? I guess that could be my next option....

Hermes cannot read some sim cards?

I have two sim cards, one for my relative and one for me. Both sim cards work on a Treo 650 I have, however, only my relative's sim card works on my 8525. The phone is unlocked and I can make calls and stuff on my relative's sim card. But when I put my sim card in the 8525, I get the invalid or missing sim card message. I have checked thoroughly that the sim card is inserted correctly.
This does not make sense. My sim card works fine as it works in the Treo 650.
Does that mean that the some sim cards are incompatible with the Hermes?

make sure its one of Cingular's new 64K SmartCards or whatever their called
their 3G Sim Cards
im not so sure if the old ones work?
they forced me to get a new one when i bought mine - even though it was already a 3g card...just an "old 3g Card" ? lol

well both of my sims are t-mobile sims, so maybe thats not it.

I have a 16k, 32k, and 64k simcard. All of them work on other phones Ive tried but the 32k sim does not work on the 8525 I have.
can someone verify this? It seems kinda weird that 32k sims do not work.

Give it some time

Few weeks ago I had to replace my SIM card, when I used the new one for the first time my 8525 didn´t recognized it, I tried then in other phones and worked fine with the others, so I call my tel co and had them to check my liene, they told that everything was OK and asked me to wait 24 hours!! I didn´t have to wait that long, it took about 5hrs and my 8525 started working as before.
BTW My SIM card is a 32K one.

seems like the problem was with my sim card, t-mobile replaced it and it works now....now to get tzones working *SIGH*

No SIM message on HTC devices? Why only HTC?

Dear friends
I had this funny little experience today - the real ghost in the machine.
I inserted a TIM Brazil SIM on a Blackstone - it picked up a signal, and then I got the message saying that the device would be configured with the operator settings and then restart. The funny thing is that after it restarted, I started getting the No SIM message.
I then tried the same SIM on another Blackstone to check if it was a result of the autoconfig process, but I also got the No SIM message here.
I then thought that the SIM card was damaged. I tried it on two Samsung PDAs and the SIM worked perfectly.
I then inserted the SIM on a Diamond - and guess what? The NoSIM message again.
I then tried all devices with a Claro SIM and all of them detected the card.
Could anyone suggest a possible line of investigation here? I ruled out that the SIM card could be defective - the problem seems to be between TIM and HTC devices.
A couple of months ago I had a similar problem with some TIM SIMs and the Tilt - it seems that their 128Kb SIM is not recognized by HTC devices. However, I fail to understand why? It doesnt seem to make much sense...
Any help will most welcome!
Thanks

Is the auto-configuration really needed. Maybe you could hard-reset your device and skip the auto-configuration, but I'm not familiar with windows mobile phone edition at all.

Autoconfig skipped to no avail
Hi
On the second Blackstone I skipped autoconfig - actually, it never detected the SIM card - very odd...
