I have bought a T-Mobile MDA Vario. I did not have a T-Mobile SIM card, so I did a SIM unlock and CID unlock.
It now accepts other SIM Cards but it keeps saying it is searching for a network but cannot find one.
I tried updating the ROM to the Molski one but it still will not find a network.
I have tried an O2 SIM Card and a TESCO SIM card.
Can anyone help??

Hi. One time ive damaged my sim card reader pins, :crying:
I'm living in poland so i had to order sim card reader from Italy, our service doesnt have any spare parts for this model
After i've changed simcard reader, my sim card is still "invalid or missing".
Dont know whats wrong. Can anyone help me ?
Reflash rom doesnt make any difference,
diagnosis all (network etc.) is disabled
SIM CARD READER has simlock ?
When I put my sim card into my US cellular Galaxy Note 3 (Model SM-N900R4) I get Invalid Sim Card under notifications. Any way to fix this?
Change sim card .
Know what kind?
My device is i9505 and it should be carrier unlocked, I bought it outside any carrier.
I have this device since mid 2013, with the same carrier and same SIM Card.
I only had 3G, and my SIM Card only supported 4G
Recently I noticed that they don't work anymore with just 3G, everyone with compatible device and SIM Card could use 4G
So I went to my carrier, and bought 4G SIM Card, it's from the same carrier I used for the last 3 years
But when I tried using it, my device said "Invalid SIM Card"...
I asked them to try the SIM Card on one of their devices, and the SIM Card worked, but on my i9505 it says "Invalid SIM Card"
I tested with my old SIM Card, and the device found no problem, but when you get a new SIM Card the old is blocked, the device recognized the old SIM Card but I can't make calls, receive calls, etc, etc...
As using my old SIM it still recognizes, I think it probably isn't a hardware problem...
Does anyone knows what could be causing this, and is it possible to fix?
I'm currently using Imperium LL v13 (Custom ROM)
I tried flashing a newer modem from my carrier based on this firmware:

I downloaded the modem from this post:
http://forum.xda-developers.com/showthread.php?p=61852508#post61852508
But it still says "Invalid SIM Card"
I also tested SIM Cards from some friends that use other carriers, these SIMs worked on my phone, and my SIM worked on all my friends phones, but when I try my SIM on my phone, it doesn't work...
On the screenshot below you can see my baseband version after flashing the newer modem:

I had the same exact problem with my I9505 with my operator digitel ( venezuela) , the only solution i had was to ask them for another type of sim card
So it turns out that Lossadax was probably right, the store that I went probably had a type of sim card that wasn't compatible or they had defective sim cards there
I had to buy another sim card from another store, the connector had different size and layout, and now it's working!
