I also just got word, from a friend that also uses Simple Mobile, that he's got no service as well with the sim in his MOFI4500.

It looks like Simple Mobile may be cracking down on modems?

I still say that typically these mean the network is not allowing your account access to the internet:

PS State: Not Attached
and
RRC: Idle

Also, are you using "magic" on the modem to match the acceptable devices for the account? Some of the MVNOs like Simple, and Metro for sure, lock to phone imeis only.

Possible. This is why some have gone to "magic", but the networks are always working on new ways to lock down to their big bizness partners only for approved devices.

We're you ever able to get this one figured out? I had a similar issue recently. After rebooting the router I couldn't get the service to connect any more. Had the same symptoms as you. Simple mobile had been nagging me for awhile that my device mc7455 wasn't network compatible. I checked with tmobile and simple had blocked the imei number on the network. Still working to resolve this but wanted to let you know my finding so far.

*Update* T-Mobile did confirm simple mobile blacklisted the imei from the t-mobile network for "unauthorized network interference" I was able to get it back online using magic for now.

Are the carriers using the MAC address to black list modems??

(Media Access Control address)

While I wasn't successful in getting support to enable service again, for my sierra wireless modem; I was able to get them to enable it on a fibocom modem by telling them that data on my "phone" had stopped working.
They obviously knew that the IMEIs didn't match, but I insisted that the phone IMEI was correct, and they allowed the fibocom IMEI to get data back on my "phone."

For my sierra wireless modem, I'm having to use Page Plus. I'm not too thrilled about the 200GB data limit for each $50 refill... But it is what it is, for now.

MetroPCS wouldn't allow the sierra wireless modem, saying that it came back as "blacklisted."

Anyone have any other ideas for providers, preferably on T-Mobile network?
