A month ago when VM was doing their update, I started getting error code 67, which prevented me from using anything but Wifi. I found online that updating my profile and PRL would fix the problem. It did for 3G, but a month later I'm still not able use 4G. My wife has the exact same phone, but she never had the error, never had anything to fix, and connects to 4G just fine. I've tried updating the profile and PRL again, but it doesn't help. If there's a way to fix this, I'd really appreciate it. Thanks!
