This will update the radio in the Maxx and give you exceptional 4G retainment. Very easy to do. Just follow the instructions
Choice 2 is: [OFFICIAL][MODEMS] Verizon SGS3 (SCH-I535) - xda-developers Do this with the Galaxy S3 and you will see dramatic results. I get 4G better than I ever did with the Maxx in 99% of the same areas.
