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.
Dear friends
I had this funny little experience today - the real ghost in the machine.
I inserted a TIM Brazil SIM on a Blackstone - it picked up a signal, and then I got the message saying that the device would be configured with the operator settings and then restart. The funny thing is that after it restarted, I started getting the No SIM message.
I then tried the same SIM on another Blackstone to check if it was a result of the autoconfig process, but I also got the No SIM message here.
I then thought that the SIM card was damaged. I tried it on two Samsung PDAs and the SIM worked perfectly.
I then inserted the SIM on a Diamond - and guess what? The NoSIM message again.
I then tried all devices with a Claro SIM and all of them detected the card.
Could anyone suggest a possible line of investigation here? I ruled out that the SIM card could be defective - the problem seems to be between TIM and HTC devices.
A couple of months ago I had a similar problem with some TIM SIMs and the Tilt - it seems that their 128Kb SIM is not recognized by HTC devices. However, I fail to understand why? It doesnt seem to make much sense...
Any help will most welcome!
Thanks
Is the auto-configuration really needed. Maybe you could hard-reset your device and skip the auto-configuration, but I'm not familiar with windows mobile phone edition at all.
Autoconfig skipped to no avail
Hi
On the second Blackstone I skipped autoconfig - actually, it never detected the SIM card - very odd...

So, I am very ignorant regarding cellphones, so I hope someone around here can help me out. I have a rooted Samsung S4 GT-I9500 that I bought in Guatemala from Claro company. I moved to Africa to work, so for me to be able to use my phone I bought an unlock code that worked just perfectly. My phone got sim unlocked and I was able to use it for several months until recently. One night my phone ran out of battery, so I plugged it to the charger and charged it all night [turned off]. Next morning when I turned the phone on, the phone was sim locked again and my sim card was not recognizable at all. the following message appears
"PIN to unlock SIM service provider"...when I click dismiss and scroll down the upper tab it says "Invalid SIM card...Network locked SIM card inserted".....
I tried reentering the unlocking code that I previously bought but with no success. I tried factory resetting and reentering the code, also no success. I also inserted my old Claro Guatemalan Sim Card and it is also not recognized by the phone. Does anyone have any clue or suggestions about what it could be and what I can do about it? Please make the explanations "for dummies" since as I said before, I am not that good with cellphone stuff. Thanks for your help.

Hello dollagaray,
I´m having the exact same issue. Did you find any way of solving it? I have flashed several firmwares and modems but nothing would unlock the phone again.
Thanks in advance!

I had this issue and ended up replacing the SIM card tray.
Hi, I recently bought a new Yotaphone2 (YD206) taking advantatge of the Singles' day discounts, but I am having some trouble connecting to the mobile network.
Since I did not have a nanosim available from the beggining, I started by updating its ROM (I used the last Russian one, while keeping the Chinese radio) and then I rooted it. So far so good.
The thing is, after my microsim was cut into a nanosim (the guy at the mobile phone store did it, using one of these "staplers"), I inserted it in the tray but it is not recognized on the phone. On the screen you can read "No sim card - emergency calls only".
At first I thought it was the radio, and I even flashed it again. I also went back to the original chinese rom, with no success. I think it's not a radio problem, since I can get some statistics in the *#*#4636#*#* menu, but I am not a 100% certain. Of course, I've already tried rebooting, setting the airplane mode on and off, removing and inserting the sim again, etc. Apart from that, wifi, bluetooth and everything else work as expected.
The sim card works, because using a microsim adapter I can fit it in my Nexus 4 and it gets signal. There are three options here: either the radio is not properly configured/flashed, the phone is faulty or the sim has been wrongly cut.
Could you help me troubleshoot the problem?
Solved!
Solved! It was the sim card, it was not properly cut. I used some sandpaper so sand one edge that was a bit rough. I didn't even have to reboot, the phone asked for my pin inmediately. I'm using the last EU rom with the chinese radio.
Yay! Happy!
I have the same issue now and my yotaphone 2 was bought in China... I've tried the sim cards from two companies, both didn't work. I doubt I received a defective product.
I have a OnePlus 6t with the latest OS version.
I have 2 sim cards.
First is from the provider O2 Germany.
Second is from the provider Drillisch Germany (Drillisch using the O2 network).
The first works fine in my device with the VoLTE and VoWIFI.
The second doesn't work at all.
I tried them both with with many different situation, like one every time or changing the slot for every Sim. Nothing change.
I tried my second sim in another device, doesn't work.
I also tried a friend's sim from the Drillisch network in my device and for unknown reason it works.
I thought there is something wrong in my sim card. So I contact the company to send me a new sim card. They send me a new one. But it also dosn't work.
Any help with the situation.
Thanks
any help here?
not sure if its related but i was having some issues with volte/vowifi on 10.3.7 and volte was getting dropped frequently and vowifi was not consistent at all even when i was using my home wifi all the time. I downgraded to 10.3.5 and its better and more stable now. you can try the same if you started seeing the issue only recently.
