How to Make Your Verizon Galaxy S III a World Phone
World phones have been growing in popularity. With devices like the Motorola Photon 4G and the HTC Rezound having world phone capabilities, Samsung decided that their latest offering should as well. Thus, the Verizon Samsung Galaxy S III was equipped with dual radios for CDMA and GSM usage. Setting the phone up for world roaming isn’t overly difficult, either.
XDA Forum Member lair12 has written up an in depth tutorial on getting the Verizon Galaxy S III working overseas. It is a little tedious and requires a lot of applications along with a rooted device, but it does not require a lot of technical expertise to get it done. The pre-requisites include:
a1- rooted the phone with stock ROM
a2- use sprint.recovery.image for clockworkmod (others may work as well)
a3- load APN Manager app from Google Play
a4 – load HiAPN Global app from Google Play
a5 – load Ghost Commander app from Google Play
a6 – load Dropbox app from Google Play
a7- load PhoneInfo app from Google Play
a8 – back up APN’s to sd card through HiAPN
a9- edit “apnlist_backup.xml” found at sdcard>HiDroid_Net>HiAPN using Ghost Commander app (select DB text editor to open) and then edit to include your required APN information. Here are two sites to check if you do not know the correct information. What I did is left the US with several options already loaded into the APN file data so I could be ready for several possible providers.
While the steps may seem tedious, it certainly beats having to deal carrying with a traditional dumbphone when traveling oversees? After that, it does get less time consuming. Simply change a couple settings on the phone, and you’re ready to go. To get back to Verizon service, just change the settings back again. Lair12 even adds a short troubleshooting guide in case something goes wrong.
