Have you tried entering bootloader and manually choosing 900/1800? I cant see why it wont work, I am using O2 payg, brand new sims work no problem, I tried 3 other new O2 sims to make sure. My xda 1 works with any sim I insert.
I would like to know exactly what happens when you insert a sim, do you get any signal, even for a second or 2. I would guess that it was a blocked phone but then it wouldnt work with the other sim, I am assuming you made a call when you tested that and that it connected ok.
If the original owner made an insurance claim on the phone it will be blocked on all networks.

This is the strangest problem I have encountered on this site, please let me know the outcome.

"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

Phone functions not working. No Service always showing.

My SPV M3100 was working fine for the month I've had it. However right after I got off the phone this morning it has been showing No Service.
The device works perfectly except for the phone funtions. When the sim card is inserted into another phone it works perfectly
I've tried a hard rest and flashing the radio.
Any ideas?

I have come across this before and the phone was blocked by the service provider! Did you buy it second hand?

sounds like the IMEI is blacklisted. Did you purchase it yourself from your carrier? or did you buy it off ebay, or somewhere/one else? If so it could have been stolen and the original owner reported it stolen
You are going to have to talk to your carrier if you purchased it from them. If you got it elsewhere you may just have a PDA and no phone because I don't think you carrier will help you in that case

I bought the phone off ebay! What should I do? The phone was orginally on Orange but I use a O2 sim on it since its unlocked. Should I call orange?

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.
