Well, my problem was solved for, like 15 hours, but now I'm back at the "Your sim card does not allow a connection to this network"
Several other people have reported that same problem. Bingley's
solution doesn't work for me.
problem resembles mine more closely. Regardless of my settings for preferred network, they return to WCDMA preferred. My sim works in other phones.
Blocked IMEI's are mentioned in the thread, so I checked my IMEI at T-mobile's site
. The message is clear: "Your device is blocked and will not work on T-Mobile’s network"
Then I checked with http://checkesnfree.com/
which shows the T-mobile block, but where it seems the phone is not reported stolen. I assume it means that the original owner didn't fulfill contractual payment. Back to check out T-Mob's FAQ: "I purchased this device from another party. How do I unblock it? Unfortunately, T-Mobile is only able to assist the party that financed the device or agreed to the annual service term with payment options or contract information.
Now, from this thread
it would look possible to use the phone in Norway regardless of the block and it certainly was
for at least a year, according to the previous owner.
I made the phone work with a variety of SIMs now, so I'm sure it's not a matter of SIM-lock - it looks like IMEI blocking made it across the Atlantic. I'll talk to my provider and hopefully there is some possibility of lifting the block.
Edit: My provider says to talk to T-Mobile. So I'm stuck in the loop...
