So there’s been some buzz that the Nexus 4 actually has a LTE chip in it.
I figured I’d test it out with my some of my SIM cards. I’ve personally tried this on Rogers and have gotten speeds of over 60Mbps. Wow.
Here's how you do it. Before you start, make sure you’re in an area that has LTE coverage. Next you need to change some settings. First you need to add a new APN:
Go to settings -> More... -> Mobile networks -> Access Point Names
hit the menu button, and choose “New APN”. Enter a name (whatever you want) and then for the APN enter “ltemobile.apn”. If you’re a TELUS user try “sp.telus.com” while Bell users should use “pda.bell.ca”.
Hit menu and choose save, then make sure you check the circle next to your new APN.
Next go to your dialer and enter *#*#4636#*#*
Choose “Phone information” and scroll down to the “Set preferred network type” pulldown. Pull down and choose “LTE/GSM/CDMA auto (PRL). Then exit by pressing back, back.
You should now have LTE support. The logo next to your signal bar should say “4G”.
I've noticed that the Nexus 4 reverts these settings every time you reboot it. So you have to go back to the network settings to check off the new APN and then go to the dialler to change the preferred network settings. I'm going to see how well it switches between HSPA and LTE now. I'll update this thread when I've done so.
