Samsung Galaxy S 4 (GSM)
Replying to: GSM\CDMA by Blackmitch1
I was kind of wondering. I hope sprint does not take the GSM chip out of the Samsung 4 like the S3. If they do it would not make it a world like Samsung meant it to to be, Big Red has a GSM chip in there Samsung 3. Take note Sprint.
You are misinformed.
First, it is not a "GSM chip." The same Qualcomm MSM8960 chipset, which supports GSM/W-CDMA/CDMA1X/EV-DO/LTE, is present in both the VZW and Sprint variants of the Galaxy S3. Sprint did not "take the GSM chip out."
Now, Sprint did not choose to have the GSM/W-CDMA capabilities enabled. That very well may have been due to technical reasons, as handsets can incorporate only so many bands/band classes, and the Sprint variant has to support a custom CDMA2000 band class (SMR 800 MHz) and a custom LTE band (PCS G 1900 MHz).
Additionally, early Sprint LTE handsets use embedded SIMs. They are not removable. That is set to change in roughly the next year, but not yet with the Galaxy S4. So, any international roaming capability would be at Sprint roaming rates; local SIM rates need not apply.
Honestly, though, so few Americans ever require international roaming that it is not something that Sprint need prioritize, especially if enabling international roaming capability would require compromises elsewhere.
