"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.

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...

Problem connecting to Vodafone on SPV M3100

Firstly, hello everyone.
I recently bought the Orange SPV M3100 on eBay, and can not for the life of me get it to connect to Vodafone with my contract SIM.
So far I have:
-Sim unlocked and superCID'd the phone.
-Installed WM6 (via CUSTEL).
-Tried 3 different Radio versions.
-Attempted to install Vodafones official update (which failed for reasons unknown).
-Played around with just about all network settings.
Basically, the device acts as if it's trying to connect to the network, but doesn't (PC speakers pick up inteference etc).
With automatic network selection it just doesn't do anything.
With manual network selection it gives all four big UK providers (allowing for signal - I live in the North York Moors) including Vodafone, but won't connect to any of them.
If I click 'set networks' I get a HUGE list of providers. Vodafone UK (if it appears at all, for some reason O2 and TMobile seem to appear on the list more often) is nearly always unchecked at the bottom. Checking it doesn't fix the problem. When I go back there later it has sometimes lost that setting and Vodafone is unchecked at the bottom again.
I should probably mention that any setting I change here results in a 2 minute "Sending new settings to the network", and on a couple of occasions has caused it to crash.
If I go onto band settings, originally they were both set to auto. Infact, I've just gone onto it as I type, and they have gone back to auto. Before it had got stuck on GSM/UMTS band type 'GSM(900+1800)+UMTS(2100)' (gave an error message unable to change band etc if I tried to change it to anything else). I cannot change the network type or GSM band otherwise without the same error message appearing.
So anyway, as you can see I've gone through a lot and read a lot unlike your typical n00b, and my prospects with this new phone are bleak.
Can anyone help me or suggest anything else that could get this phone onto Vodafone?
I have a worrying thought that this phone could have originally been half-inched (the eBay seller seemed a tad on the dodgy side), been reported, and is now serial-blocked from UK networks, if that's possible?
[edit] I don't know if they are or can be serial blocked, but in which case, assuming you trust and sympathise with my story, is it possible to hack & change the serial number?

Sounds possible that its been blocked. Yes there is a way but you probably won't find any help on this site to do it as it is illegal. Thats not to say you can't search the site, you may find something that may help... Search is your friend...
Cheers...

Yeah reading into the problem reveals a possible 'IMEI' block.
Time to contact the ebay seller I think.

Have spotted an obvious hole in my theory:
The thing came in it's original box (s/n sticker confirmed) with all manuals and accessories.
So back to original problems; is there anything else I have missed?
[edit]
Phone is unblocked according to http://www.amta.org.au/default.asp?Page=405.
So unless they're wrong, why can't I connect to Vodafone and what else can I try?

did you try *#06# on the phone to be sure the S/N on the stickers and phone is the same as the actual phone S/N?

Yes, they are.
Would Vodafone be of any help on this issue?

Depends if they supply that model of phone.
Do you have a network configurator app cooked into the rom you are using or are you using a stock rom?
Might be an idea to look for a network configurator cab if you're using the stock rom and see if that helps. Also if you are using a stock rom, and its not setup for vodaphone, it MAY (don't quote me on this) be affecting the network settings and making it incompatable with the carrier you want.
Just a thought...
I'd also try to run the sim unlock app again, just remember it has to be the SPL that was supplied with the sim/cid unlock tool. Make sure you install Hard SPL V7 back after checking this...

vodaphone will help you if you ring them up using a the sim card in a working phone and ask them to check if its imei is blocked, they do it totaly free of charge.. had to do this with a viewty i bought from a work buddy shorty before he forgot to tell me he did not pay the contract bill and t-mobile blocked it. well annoyed, but they told me it was reported Lost or stolen.
found a few places on the net that offer a check for £10 sod em lol
luckly got me cash back selling it for parts hehe

What a bloody carry on!
Vodafone told me it was blacklisted; reported stolen.
The eBay member is highly upset at being called a theif and very convincingly tells me otherwise (I'm 90% sure I can believe his story, and feel bad for my accusation).
Orange (of whom I'm not even a customer) then tell me "I'm sorry it's blacklisted for an unknown reason ... <click-click> ... there you go sir I've removed it from the blacklist!"
Well, if it starts working again in the next 48 hours I couldn't give a monkeys what's gone on. I just want the bugger to work!

the only reason that a phone would be blocked is if it was reported.......have you tried another sim from o2 or orange etc.
the question has been asked before about imei changing and as you know its illegal,but can be done so if all else fails search elsewhere,not here, i would suggest that unblocking a phone is never likely to be an achievable goal.the networks are not known for their magninimity

How to turn the network lock back on?

Hi!
I have a network unlocked HTC Dream (english T-mobile-version) that I bought used and unlocked. The previous user hade Tele2 as his operator but I used Telia. I´m now in dispute with him because the phone never worked with any calling och messaging but data works fine after manual APN-settings. I have now recieved the unlock code he got to unlock the phone, but with it being unlocked already it doesn´t really help me right now.
The plan is to somehow revert back to a locked phone and unlock it with my SIM sitting inside, and by that maybe fixing the problem.
So how do I make the phone go back to being locked to T-mobile?
Best regards,
Christoffer

It sounds like it might be IMEI locked on the network. T-mobile in the UK will allow blacklisted phones to connect even though they cannot work and there seems to be a loophole where data gets through. Maybe the case is similar, ring your operator from another phone and ask them.

Well I am not sure why you can access data but can't make calls. It would seem to be some type of carrier problem or something I don't know about. I do know that you definitely cannot re-lock it, once it is unlocked it stays that way unless tmobile can do something with it. Something is either wrong with the phones hardware or your carrier, if it is a software problem maybe try flashing a new rom and re-enter your APN stuff.
Try making a emergency call like 911 or whatever, if that doesn't work something is screwed.

I tried it out this weekend with a friends SIM who is on Tele2, and it worked there with no problem! It is so weird that it acts like it was network locked, even though it shouldn´t be.
I´ve seen that a few have posted about the same problem, mainly with the Dream but also with the Magic. It comes up as "Telia" but follows with a "(No Service)". About 24 hours after I recieved it connected to the network and worked fine for about 10 hours but then it stopped working just as I got a MMS I was about to download. If I try to manually connect to the network from the list of operators, it says that my SIM "isn´t allowed to connect to this network".
I´ve downgraded and upgraded Radio to try to solve this, nothing worked.

I dont know alot about foreign networks but if you can get data then you should get all services. That message you got "SIM isn't allowed to connect to this network" is what you should get when your not unlocked. Or if the SIM is trying to use another carriers cell tower, your sure you got the APN settings correct? It sounds like you have some sort of hardware problem if the switching of Radios didn't help. Can you try the same SIM in another phone and see what happens?

I use the same SIM daily in my old phone the Dream was supposed to replace, works like a charm with everything.
It can´t be a hardware problem when the phone works flawless with Tele2, or can it?

Well it is just weird the data works and not calls. I am just guessing what it could be. Maybe something with the carrier? It's a odd problem.

Did you ring your operator? Put the SIM card in the phone, turn it on, then ring Telia from another phone. They should be able to tell you something. If it is blacklisted, they do not always share this with other networks.

That might be a thing to try. I have been in contact with Telia and gave them my IMEI-number but even during the short period the phone worked (by chance) they say that IMEI has never been logged in their system.

NOOB - T-Mobile UK HD2 unlocked - no O2 connection..

Hi guys.
Really sorry about this but I am at the end of my tether with this!
I run my own IT support company and one of the things I do most is Blackberry and iPhone Exchange email syncing. While both of those work brilliantly, I have had users having loads of issues getting their Windows Mobile devices working easily. Luckliy only one or 2 have these devices but more are asking....
I resorted to retiring my Bold 9000 and got a brand new sealed HD2 on the UK T-Mobile network today. First thing I did was get a sim unlock code and that went through first time (using my working o2 SIM from my BB). However, I couldn't make calls so after I spoke to o2 I got in to the Phone, Network settings and with the Network selection on auto, the preferred networks list was blank. Clicking the preferred networks button brings up the list of preferred networks, ticked o2 - UK and ok'd it. Goes back to main network screen and still blank. Clicking Find Network then brings up cannot register on selected network.
Changing automatic network selection to manual, selecting )2 - UK and ok'ing that brings up the same 'cannot register on selected network error. So, after coming here, I stuck on the HSPL 1.42, then upgraded to RUU_Leo_HTC_WWE_1.48.405.2_Radio_Signed_15.28.50.07U_2.05.51.05_2_Ship
That went on fine and after wiping to factory to make sure I sent through the set up. Same errors and still can't make receive calls.
Stuck on the 2.08 hspl for the hell of it then upgraded to RUU_Leo_HTC_WWE_1.66.405.2_Radio_Signed_15.30.50.07U_2.06.51.07_Ship
Guess what? Exact same problems! I spoke to o2 support and they were pretty useless. Explained that it was sim unlocked and on a generic firmware. They said that T-Mobile do something weird with the HTC and I should try calling HTC tech support, who are now closed...... I am not sure HTC will be of any help anyway as I can't exactly go telling them I have stuck on the HSPL and a non-approved firmware for what was the originall carrier!
Help please anybody?? I have googled and googled but haven't found anyone with the same problem, I might be being blind. BTW, what I guess is the antenna icon has an exclamation next to it
Thanks,
Nick

Quick update. Housemate got back so I nicked the Vodafone UK sim from his iPhone and stuck that in the HD2. Same problem, won't register on Vodafone either. Anyone?

Got annoyed. changed the SPL back to the standard 1.42. Installed the latest T-Mobile official firmware. Same problems. Do I have the only HD2 ever to be doing this? . I don't have a T-Mobile sim to hand and the nearest store is miles away sadly.

Does your phone app not work at all ?
How do you know unlock code worked ? so far every sim you tried has failed.
Where did you get the unlocking code from ?
How did you use it ? meaning how did you input it ?
Verdict so far, if a t-mobile sim card works then unlock was a fail !

Ok referring to your network selection, for the UK, you should have it set to Automatic, it will then use the network associated with your sim.
referring to your call problem, does the phone still work with the original t-mobile sim?
if so it sounds like your unlock code didnt work.
if your phone no longer works with the original t-mobile, I should think something has gone wrong with the radio software you have installed on the phone. Try going back to the stock htc/radio rom. If that doesnt work then the phone probably needs to go back to t-mobile for repair, at this point you tell them "it just stopped working"

have you tried to run the connection setup wizard?
settings - menu - all settings - connections - connection setup
if there isn't one, connectionsetup is available as a cab.

Hi guys. It was a brand neww, sealed box HD2, but from T-Mobile. No SIM with it at all or I would have been trying that too of course .
Regarding how I unlocked it. I paid an ebay seller to give me an unlock code. When I fist put on 02 SIM in the phone it wafffled on about being network locked basically and had a field to enter the unlock code. Entered the code given to me via the Ebay unlocker and never got that message again on the screen. Is that wrong somehow?
Manual network, auto network, selecting carrier etc all of them make no difference. I am off out now but have found a local store with PAYG T-Mobile sims in stock so will grab 1 later today and see what happens then.
Will update/bore you all later!
Cheers,
Nick

Right, case closed. I got the T-Mobile sim and stuck it in. Showed up with T-Mobile on the scren and a good strength signal. Tried to make a call, dropped back to the home screen almost straight away. I had full data access though. Spoke to T-Mobile who informed me that my brand new, sealed box HD2 was blacklisted and I could do nothing with it!
Vodafone and O2 just flat out don't let you register the handset on their network if is it blacklisted it would seem.
Contacted the seller and he has arranged a refund, but the refund is showing as 'pending' so I am not going to return the phone until I see it physically in my account.
I have to be honest and say that this is actually a good thing as despite HTC doing all they can to make the Win 6.5 on there look less dog-like, the overall UI is still pretty awful. Now,this phone with Android 2.1 on it might be a dfferent matter! Back on my Bold 9000 for now......
Cheers,
Nick.

I am sorry to hear about that, looks like to you got hit by some sort of scam, probably resealed a second hand or refurbished unit into an original box and sold it as new.
regarding the UI of the htc devices, I am not really sure why you think this, htc hd2 uses htc sense which is the same ui as on the android htc phones. The only windows mobile thing you should really see is the start menu which has been praised as being a very good replacement for the old start menu. even all the settings windows are run through the htc sense ui so i am really not sure what you are complaining about :S
If you dislike the top bar/bottom soft buttons, there have been a lot of modifications to these in more recent hd2 roms, maybe you should to take a look at the roms section to see some pics.
