I just received an Optimus G and had to unlock it to be able to use it. I I unlocked it myself with a code and it worked. Then I entered and saved the current Rogers mms apn settings. But then I go to gsm/wcdma/lte, I don't get LTE or any data service and it shuts of my cell service as well. I have triple checked the current apn settings in maaany places and am sure that mine are entered correctly. Any ideas?
