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.
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....
I brought a 8125 from ebay it had a cracked screen. So I had an PPC 6700 that had a bad radio so I took the screen out of it and placed it in the 8125. Everything worked great but when I turned it on it cam up with the message " Invalid or missing SIM card". I placed my Tmobile SIM card in I turned on the device and it reads the same thing. I read all the posts that I can find about this and they really didn't have much about it. I noticed that its searching for the network buy looking at the signal indicator but I also noticed the the led to sho that the phone was on doesn't blink. On some of the posts that I read it stated that if someone put the wrong code in to many times that the phone will be "counter blocked". I think maybe thats what happened with the last owner of the phone did. I at first unlocked the sim with the sim unlocker thinking that was the problem was but it still didn't work. My question is if it goes in to the counter blocked mode does it prevent the software from unlocking the sim. My other question is what is the file's name that when you place a sim in the phone that it runs to enter the unlock code on the phone? I was thinking maybe if I run that file manualy that maybe it will get the phone out of the counter blocked mode and then I can try running the software unlock again. Things that I have done to try to get it to work was sim and cid unlock, flashed tmobile rom to the device checked the contacts in the sim holder to make sure they are touching the sim card. Any ideas?
Sounds like it may not be a software problem. If the device was legitimately software blocked, it would display that, instead of 'invalid/missing SIM'. If it's IMEI blocked, it would have accepted the SIM but been unable to connect to the network.
The problem is most likely either the SIM itself or the onboard SIM reader. Try obtaining another SIM card and seeing if the device will read it.
Hello,
I upgraded without no problems my Polaris to WM6.1, from the HTC site.
Aparently everything works fine, except one thing: when i turn on the Polaris, it does not ask anymore for my SIM PIN. I have a SIM PIN set, but when it boots it apears just for a milisecond the screen where i have to put my PIN, an after that it just boots in Today menu, without connecting me to my vodafone network, or asking me for the SIM PIN. But when i press the green phone buton asks me for SIM PIN, and the connects me to my network.
In WM6.0 when i was turning on the phone it always asked me for SIM PIN in booting.
Can anyone tell me if there is a solution for this......or if this is normal to happend?
Thank you very much.
Hi ,
after upgrading I had a lot of small problems , but not yours.My solution was to install this rom :

...And everything went to normal again or better .
Best regards /
i was with tmobile and the phones ok, with that sim in there - even though it's inactive now. i've moved my number to o2 but when i put their sim in the phone, i get android.com.phone has stopped over and over again. i can't get into the mobile network part of the phone as it says to insert a sim.
thing is, the sim works fine in my old sony c905 so it can't be the sim can it? i could call from that phone and everything worked fine.
i'm going to install a rom from scratch later on and see what happens in case it's some funky software freaking out on the sim change.
Is this a standard SGS2 with no network lock?
If you have flashed a custom rom which do you have on there at moment?
try new rom or desimlock your phone
it's not a locked phone and am running criskelos at the mo.
i put the sim in the c905 again, enabled the sim lock, put it in the sgs2 again and on boot up it makes me enter that pin. after that if again doesn't see the sim for some reason
installed same rom from scratch and it works. very freaking weird!
