"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.

Universal simcard problems

Hi all
I've just changed mobiel provider from Telmore to Unotel in Denmark and I'm having some trouble with the new simcard.
The simcard I got from Unotel is not recognized in my Exec. There's no real error message. The phone app just reports: "Invalid or missing SIM card"
I've had some communication with Unotel support and they claim the problem is in the Exec not accepting simcard with lower capacity.
Their simcards is 16k.
Unotel can not provide me with a higher capacity card so I was wondering:
Has anyone else had this problem and is there a cure?
Telmore and Unotel both use TDC's gsm/umts network.
I've had not problems with my 32k Telmore simcard and the 16k Unotel card works fine in my SE K700i.
Kind regards
Asbjørn

your phone is sim locked

No I'm afraid that is not the problem.
I can use other simcards from different operators without any problems.
It's only the 16k Unotel card that causes me problems

Had exactly the same problem, had to change from CBB to "3" to solve it.
Nothing wrong with your phone.

I was hoping that it didn't had to come to switching operator one more time.
Since it's properbly a general problem with the Universal and low capacity simcards I was hoping someone (smarter than me) had encoundered this problem and solved it.
Or at least is able to confirm the problem is just related to 16k simcard and doesn't have to do with a special coding or something like that.
This way I can confirm with a new operator that it will not be a problem.

NewZealand Vodafone SimCard not working ...

Hey guys,
I finally got my P3600 send over from Europe ... (none branded HTC Version... so no Vodafone Lock or so) However, if I insert my German SIM it will be recognized, but if I do the same with my NewZealand Vodafone Prepaid it jsut tells me that there isn't any SIM inserted Both Sims work fine with my German Nokia so I am not sure what the problem is.
Does anybody have a similar problem or know how to fix this?
help really appreciated

Hi rodpacker
Welcome to the short list of members with a P3600 in NZ
Unfourtunatley I can't help you at the moment, I have a VFNZ OnAccount SIM that works fine, I guess I could try out my missus PrePaid SIM if you still can't get it to work after a couple of retries.
If you live in Auckland you could rock into CoolMobile or ETown, they were selling P3600's for a while and may have come across issues with PrePaid SIMs.
Not that it would make any difference, but do you have a SIM2 or older SIM card, and what size KB is it? Also I presume you have credit on it....

I had a similar problem when attempting to use my old China Mobile SIM, and got it sorted by getting the later version SIM card.

hm, good to hear that there is some others
I got a vodafone prepaid I bought like two months ago....Not sure which version it is. It says 128k and 3G on it. Does that tell u guys anything?
thanx heaps for ur help...
and jep I am in Auckland. Although got two p3600's and gonna sell one of em soon ... brand new!
How much where they when they were sold over here?
cheers
Rodpacker

tried another prepaid .... still no luck
last night I thought I might have to unlock my phone and it wasn't unlocked as I thought, however after ur message concerning NZ SimCards I doublechecked again and after using a German Medion Simcard, that worked I tried a UK O2 prepaid and that worked as well...I even got roaming going...So I guess I can save myself the hazzle of reunlocking the device...
Now could u maybe give me some more hints on the problem with NZ Vodafone Simcards?
thanx
Rodpacker

Hi rodpacker
A 128k 3G SIM should work. Have you tried your new SIM in another phone to make sure it's not a dud?
The P3600's were going for around $1200-1300 (NZD). Not sure why they stopped selling them (maybe because they wern't selling ). I got mine imported from the states for $800NZD delivered in box with warranty, so that's what you would be competing with to sell your spare.

jep card is working in my other phone atm ...
thanx for the price info...
good to know. Still busy skinning mine with the iphone skin and ipod player...since touchFlow isn't out for our model yet... will go to those shops u were talking about tomorrow
cheers
Rodpacker

Hi Rodpacker,
Sorry for my english..
about your problem, I remember a forum with a boy with similar problem...Can you try to speak about your (NZ) vodafone customer service. If i remember well the cust.serv unblocked a sim...
If I have not understand your problem, sorry
Bye

I think I'm about the only one who actually bought a P3600 retail in NZ, at the time it would have cost more to get it in from overseas...
But I'm probably not much help, my SIM is also on account - and is an ancient one as well! Was one of the original SIMs before the days of SIM2...
What radio version does your one have on it? Go to Start->Settings->System->Device Information to check. I've had issues with one of the later radio versions (1.46.x) in NZ, accepted the SIM ok but couldn't receive any calls. Currently using v1.38 which seems to work ok.
The radio ROM talks to the SIM, so this could be the issue.

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.

No signal on stock rom

So,
I was using my XT-1563 on a CyanogenMod in one of my local carriers. I bought a new phone and decided to sell this one, so I went back and installed stock rom. So far everything was ok.
The problem came when the person that was buying it tried to use her simcard. The phone didn't show any error, but it never connected to that network. Then I tried another sim from different carrier and it didn't work either (but it does work using my old simcard). It recognizes there's a new simcard, but fails to connect, only allowing emergency calls.
I've been trying all day to fix this. I have flashed nearly half of all the stock roms available, obviously starting with those from my zone, but so far none has worked.
I also tried the simcard into my new phone and it works just fine.
So, I know the following:
- The simcard is ok.
- It's not a signal problem (I have tested it in different parts of the city and zones I know have very good signal).
- The phone works using a simcard from one carrier, but not the others (and it doesn't ask me for some unlock code).
Thanks in advance for any help, it'll be greatly appreciated.

So, did you ever carrier unlock the phone? I realize it's not asking for a code, but you never said you actually unlocked it.

At this point I'm not 100% sure.
When I bought the phone it was supposed to be unlocked (I got it from someone else) and I'm pretty sure it was, because it was originally bought for one carrier (Entel Chile) and then I used it with another one (Wom Chile). By law, every phone sold in Chile since a few years is mandatory unlocked and this one is not that old (2015).
Right now it only works with Wom Chile, even tho I've installed Entel's stock rom. I think it's some baseband issue from what I've read, but I can't be sure.
P.S: Sorry for bad english.

Yes u r right
i used cm14 on xt1562, i'v feel my network was drop around 30-40% specially on Reliance JIO 4G VOILET.
Over all - rom is good for enjoy but not for stability
