[TIP] Wind Mobile GSM/WCDMA Fix

[morrislee]

When I first bought the Amaze 4G from Wind Mobile, the store rep told me to put the "Preferred network mode" to "WCDMA only". That was fine until I started realizing that it still goes back to "GSM/WCDMA auto" when I reboot the phone. THIS IS DANGEROUS! You will get roaming charges!

To fix this on Wind network, which will make sure it always use WCDMA on "WIND Home", you need the following:

- Rooted Amaze 4G
- adb or root explorer

In this guide, I will use root explorer. If you do not have this app, you should learn how to use adb instead and save you a few bucks

In root explorer, navigate to /system/ and find "build.prop", make a copy of it in the same directory and to your sd card if you like. Tap on the top right where it says "Mount R/W", then long press the build.prop and select "Open in Text Editor" and look for the line shown in the screenshot below:.

Change the highlighted value to "2" (without quotes) so it looks like the following:

Once that is done, press menu and "Save and Exit" option, you should now see something like this:

Reboot the phone, and go back to the "Preferred network mode" option, switch to "WCDMA only", the setting should now stick even after reboot. if it does not comment below and I will try to help you.

Great tip, my first month with WIND was about 40-50 bucks on top of the regular 30 I pay. I called them, complained (because apparently WIND's reception is so bad sometimes it turns into roaming when there's no reception and ends up charging me) and got the additional fees waived. You can also call them to disable data roaming for your particular account

Humm.. thanks, but I would like to be able to call when I actually need to. So this deemed to be a more optimal option for me sacrificing warranty of course.

But I will for sure know now that I need to pay attention to my bill, I only have this phone and Wind service for 5 days

I'll look into making a .bat script if possible. Good idea.

Might be able to make an update zip, that would be easier? If not, you would just copy the modified prop file and push it using adb, chmod 644? should work just like that, have it backup the current one first though, because I can't find the stock image for Wind Mobile version anywhere.

When you get it to work as bat, feel free to add it to your toolkit

I'd like to make one that pulls out the build.prop, replaces the line with the new edit, push it back to the phone. I'll look into it later in the week. Focusing on school atm.

What if you need to make a phone call while roaming? WDCMA won't cut it, you need GSM

Yes, but if you are in roaming, you will get charged for receiving text messages. If you do this, you are still allowed to switch back to GSM when you like to.

I'm pretty sure I called them to tell them to disable roaming data only for me, which means that roaming calls and texts would still work. Roaming calls are typically 25 cents per minute and roaming texts are typically 15 cents per message sent, so I'm not worried about that at all.

The only thing you really need to be looking out for while roaming is data. If you're caught in an area where WIND has bad reception and decides to say that you're in the "AWAY" zone, roaming data fees will apply! They charge you 10 cents per 25 Kb - that's roughly 4 bucks per megabyte!

I don't see how that is retarded, the part that she did not mention it gets reset when it reboots? Not everyone knows how every single device operates.

Once ICS is released, I will start developing for it. This will be included

Wind user only though
