Hi All, I seem to be having a unique problem. I've searched the Web, gone to a T-Mobile store (A bunch of useless idiots), called Google Nexus support, called LG (Equally as stupid as the T-Mobile employees) They could not help me in any way whatsoever. As the title suggests, my Nexus 4 is not getting any signal with a T-Mobile SIM inserted. I used the phone on AT&T for 2 months with no problems at all. I've tried multiple T-Mobile SIMs and AT&T SIMs and the results are always the same. The phone is pure stock. No modifications. If anyone has any sort of knowledge or experience with this issue, your comments will be greatly appreciated! Thanks!

Help Nexus 4 (used on ATT previously) not working on T-Mobile
Its not clear if the phone and data are not working? Can you put your Tmobile Sim in another Tmobile phone and it work? If you can and the phone works then check your APN settings to help with the data issue. If your Sim works in another phone but you can not call out on yours. Warranty phone return.

Sounds like the phone isn't updating the settings automatically when you switch SIMs.
I believe you can find the settings on t'interweb and amend them on the phone manually .. I have no idea how its done, though - presumably some far cleverer person on here will know, though
Of course, as bhero suggests, it might be better to simply have the phone fixed under warranty (I doubt they'll give you a new phone after 2 months) so you don't have the same issue next time you switch networks.

I had a similar problem when switching from an AT&T to T-Mobile SIM. There were 4 phone stores in a single block of buildings, and most suggested that the Boost Mobile actually had a technician that might be able to assist, so I went there. The kid behind the counter recognized the problem almost immediately as a mis-cut SIM, but of course that thread was presented for your consideration as you created your OP, based on your keywords SIM and T-Mobile. Still, the images I posted are worthy of your consideration.
Does that mean the T-Mobile SIM(s) always fail, while the AT&T always work? Certainly the phone states "no SIM card detected" or some such when booting?
Your problem sounds exactly the same as mine, so check the thread above and see how your T-Mobile cards are cut. I only tried two, but they were both mis-cut, so I cut a full-sized SIM myself using a cutter at a Radio Shack store, crowding the side away from the corner bevel as in the pictures, and it's worked perfectly ever since.
You don't state if your carrier is T-Mobile or some MVNO using T-Mobile, so I can't help with your APN settings, but of course it's necessary to have those settings correct as well.
