I've been putting off asking the question as I thought that somebody else had to have gone through this already but I've had poor luck looking through the forum and Google hasn't been able to help.
I'll be traveling to Italy in the near future with my Verizon Samsung Galaxy S3 (Build KOT49H.I535VRUDNE1). I would like to pick up a TIN or WIND SIM while I'm there, primarily for data usage. From what I've read, once I install the 3rd party SIM, I'll need to update the APN settings to get data to work.
Stock, it looks like the APN settings are uneditable. I rooted the phone with towelroot (if only everything were so easy) and then checked the APN settings to see if I could add another network. No dice.
Poking around on the web, it looks like in the past, people have been able to work around this by downloading build prop editor and adding the following two lines:
I gave this a shot and was surprised to see the APN menu gone when I went back into my network settings. Through trial and error, I determined that the inclusion of ro.csc.sale_code=LOL changes my Mobile Networks options from:
- Mobile Data
- Global Data Roaming Access
- Signal Strength
- Network Mode
- Access Point Names
- Network Operators
- Mobile Data
- Data Roaming
- Network Mode (GSM is not an option in here)
- System Select
- Dial Up Networking
There is no option to modify APN settings there. Am I missing something silly? Did something change in KitKat 4.4.2 that has caused this approach to "unlocking" the APN settings to become invalid? Is everything really ok and I'll have access to the APN settings when I insert the italian carrier's SIM card?
I'm game for other approaches as well. At one point, I thought I saw an article that talked about setting up a pointer to the APN settings prior to updating the prop file but I haven't been able to relocate that.
Any suggestions would be appreciated.
