I have been receiving this notification frequently on my unlocked LG Nexus 4, along with a similar one saying "Restricted access changed - All voice services are blocked." Could someone help me solve this? I tried various things to fix it: factory reset, changing the default mobile network from GSM/WCDMA to WCDMA only, numerous reboots, replacing the SIM card, etc. But no luck.
This started on August 1st (almost 6 weeks ago) when I returned to USA from Europe, and it only occurs when I am at or near my home. It runs the battery, makes calls and texts unavailable at times, and most of all is SUPER ANNOYING. I was convinced that when I did the factory reset (finally got around to backing everything up yesterday) that it would solve the problem but sadly, it did not. I am very frustrated. I have researched several threads regarding this issue, but most end without really explaining a solution. My assumption is that the phones are the problem and those users swapped for a different phone, but I'm just guessing. I plan to go to the tmobile store today and maybe see if my sim card works in another phone, but the problem again is that this only occurs when I am in a certain area, i.e. my home. I don't have another unlocked phone I can test this on, so I'm running out of answers.

There is some setting in the Nexus, I believe, that needs to be changed. It wasn't/isn't, as I recall, sold by TM and had to be bought directly from Google. In the past year, Nexus owners have placed posts about trouble using the phone overseas.
An active member on this forum, dnewcomb, knows about this, as I recall. Maybe he or someone else will post the "fix" you need to do. TM has enuf trouble supporting phones that are TM branded. The Nexus doesn't have wifi calling, as I recall,because it isn't a TM branded phone.
