While it is still impossible (legally, anyhow) for users to transfer CDMA devices from one big provider to another (e.g. Sprint to Verizon), it is quite possible to switch from a big CDMA service provider to a smaller one. With tutorials on how to flash various CDMA devices to smaller carriers such as Boost or Virgin Mobile, users with CDMA devices may very well have more freedom than they initially assumed. For instance, owners of any of the HTC EVO devices, including the HTC EVO 3D, HTC EVO Shift 4G and the HTC EVO 4G can now flash their phones to a service provider named Page Plus.
XDA Senior Member Nevell has written a universal tutorial for all three devices that will get them off of Sprint’s network and onto Page Plus’ network with a little patience and a few modified files. The process is pretty long and will definitely take some time for first time users. The list of required software is pretty decent as well, including:
CDMA WorkShop (Paid or Demo) http://www.cdma-ware.com/workshop/demo/cdma_workshop.rar
Page Plus PRL’s (See below)
APN Backup and Restore
Page Plus APN’s
Of course, you’ll need to be rooted in order to get the MSL and the HTC Drivers, including the Diagnostic Drivers to make it work as well. Next, there are many of small tasks, from obtaining the MSL to changing the APN. All in all, not a difficult process, but users attempting to do it should be very careful to follow all instructions to the letter to avoid messing anything up.
