"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.

"Not registered on network" "No Service"

Ok got this phone but it wont ring or recive calls ! .
After putting in my SIM card, entering my PIN code it still says no service. When you try and make a call it says "Not registered on network".
It was on T Mobile which I have had it unlocked via eBay. I got past the Google registration page by entering APN settings for my SIM card (O2).
Now I can user the browser and market etc but no calls.
I have done everything in THIS thread and think I have flashed it with
JFv1.43 RC9. (When I say think it seemed to flash but I cant see any difference so not sure if it worked).
Does anyone know how I can get the phone to work?
Thanks for your time

i have been in this same situation for about 3 weeks and after spending countless hours on phone and at store with tmobile 3 replacement phone 5 sim cards and a new number they close my account and reopened it this was just tonight so i am testing it out so far i have lost servie twice within 3 hours restarted my phone both times and regained service so im not sure if it is completely fixd just yet

Its really annoying such a simple thing. When I try to manually select teh operator in settings it says "Your SIM dosnt allow connections to this network".
I tried an orange SIM card and for some reason it puts the phone in airoplane mode and wont come out :s
Any ideas would be appreciated.

Anyone got any ideas on what could be causing this ?
Thanks

same boat
man I'm telling you that's been happening to me. except I upgrade to ION and then reverted back to haykuro's 6.0r1. everythig that;s happened to this guy has been affecting me

No service
I also have a problem with my G1. Bought it from my local polish netwerk (Era) and the phone works OK however, from time to time it looses the connection to network and it needs a reset in order to login to network again. Don't remember if it happened before they released the software which supported polish language. So what do you recon is it a hardware problem or did those useless local IT guys screwed sth up while translating android??

hi i have he same problem stuck in airoplane mode and no service has anyone found a fix yet????

I´m yet another user with the same problem. For a few hours yesterday I suddenly had service, but it stopped working in the evening again.
Any solution?

A similar problem. Tell me what to do. Thank you.

hey guys not sure if this helps but if your device is rooted did you try un rooting it? maybe get it back to stock firmware...? or do you think its your sim card?

I just bought a fido sim card and I get the msg: "cannot register on this network. choose another network, or disconnect your data connection and try again" when i try to manually connect to the network. I have using this phone with at least two sim cards back in my outcry and i bought it independently from my previous network from an eshop in Ireland..
Any thoughts? Could be the ROM and radio installed?
edit: I now saw that this isnt a thread for HTC Touch HD

SIM Card Full Error

Hello All,
I am using HTC touch for a while and would use different ROM versions quite often. Recently i put in the some ROM which event i don’t remember which one i started getting this error below. I checked and made sure that there is nothing in the SIM card i also put in the SIM in different Cell phone to make sure its blank. I also reverted the device to the Factory Image but still the same issue. There is no pattern on when i get this error it would some time come twice in 1 hour and some time it would be couple of hours. Once i get this error and select Ok my network will go to searching and often end up enable Flight Mode and then disabling it.
"SIM card full. The SIM card is full. You must remove some messages from your SIM card to receive incoming SIM messages."
Any pointers are greatly appreciated.
Thanks,
Jasjit

it will be necessary for you to call the carrier to locate a retail location near you that has a Cellebrite device... not all locations have one as they are quite expensive... using the Cellebrite it is possible to wipe/edit your SIM...

this happens sometime with my device also.
but in my case i just clean simcard and reinsert it.
may be u have faulty simcard or sim socket .

[Q] Complete Noobie Question

Hi, I've just purchased and HD2 running W7 (aMAGLDR V1.12 on the load screen), I've hit a problem which hopefully someone can help with.
I installed my new 3 Sim and the HD2 worked as a phone but the 3G wasn't working. I tried my mate's Virgin sim and got the same result.
I then tried my 3 Sim in his Xperia and it started setting up the 3G connection for him which we cancelled.
Put the 3 sim back in my HD2 and just get a 'No Service' message and what looks like a stop sign in the top left hand corner (it's hard to tell as it's mainly black on black). It knows that Sim is there as I get the No Sim screen if it's not installed.
Am I correct in thinking the stop sign means the Sim is locked or is it something else entirely ?

Did you change the phone's APN settings to your carrier? You won't get data service if you don't have the correct APN settings entered.

Yes I've put in what I believe are the correct APN settings, there the same as ones I found on here.
When I do a Network Selection for the 3G it finds 3 amongst others, but the active network section just shows 'no network found'

one Samsung Galaxy S4 EE sim says 'invalid sim other OK

I have 2 Galaxy S4 i9505 phones.
Phone 1. Bought as used phone on Ebay and was previously locked to the 'Three' network, I had it unlocked by 'Three'. This phone has always, and still does work without problem with my EE 4G (pay monthly) sim. The only remarkable thing about this phone is that it failed/froze/bricked whilst installing the Lollipop upgrade. It was repaired - new boards - under warranty in April 2015.
Phone 2 was also bought as used on Ebay. This phone had been used on O2 network. I discovered that it had never been locked to any network. I bought a pay monthly 30 day rolling contract thinking that it had been locked to O2. When I put my EE 4G sim in I got the message 'no sim, insert sim'. Baffled. The only thing I thought could be the problem was the sim itself, EE gave me a new sim. The only physical difference this sim had was that it had the Nano option. When I put this sim in phone 1 it worked perfectly, I put it into phone 2 and it worked! I needed to put the sim back into phone 1 to set it up to transfer data. When I put it back into phone 2 the message 'invalid sim' came up and that is where things stand.
As I have two phones I was hoping someone could guide me through the necessary steps to find out where the problem lies by comparing the two, and hopefully find a solution. I have read another thread from tomedwards93 posted in April 2015 and see no solution was found by him so maybe this could help him too.
Can someone please help?

I didn't understand a single of what is written,the description is long and read this thread twice,still can't a understand this thread

I've replaced the sim card slot and done a factory reset, it worked for about half an hour then the 'No sim ' message returned. It still works with a PAYG '3 network' sim, with intermittent 'sim removed restart phone' message I no longer have the O2 account.
I have another fully functioning S4. Can anyone guide me through comparing the Android settings on the 2 phones.
I've never attempted either flashing or rooting and don't understand how to go about doing this.
Just to say thanks for the suggestions, the phone has now corrupted my SD card and I've had enough, I'm defeated. I'll keep this phone as a Sonos controller and go to Lumia 950 on Win phone 10 when it arrives.:good:

Sim not detected
I have a samsung S4 i 9505 and I often receive a message "insert cart sim". After rebooting it works normally
