Hello every one,
I made this question in another thread and I was encouraged by a CB Master to make this a separate thread.

I'm about to buy a Z10 the thing is there are 5 models. We all know the STL-100-1 has another processor (Texas Instruments OMAP 4470) and the other 4 models have (Qualcomm Snapdragon S4 Plus) processors. I have been reading and watching some video and if I don't misunderstood the Qualcomm Snapdragon S4 Plus is faster (I know both are 1.5 GHz) but still seems to be faster.
I live in Argentina and the Z10 STL-100-1 is the one carriers are selling here. If it is true that Qualcomm is better than Texas Instruments, I was wondering if any of the other models will work here.

STL-100-1
2G Quad band GSM/EDGE (850/900/1800/1900 MHz)
3G Quad-Band HSPA+ 1, 2, 5/6, 8 (850/900/1900/2100 MHz)
4G N/A

STL-100-2
2G Quad band GSM/EDGE (850/900/1800/1900 MHz)
3G Tri band HSPA+ 1, 5/6, 8 (2100/850/900 MHz)
4G Quad band LTE 3, 7, 8, 20 (1800/2600/900/800 MHz)

STL-100-3 (RFK121LW & RFF91LW)
2G Quad band GSM/EDGE (850/900/1800/1900 MHz)
3G (RFK121LW): Quad band HSPA+ 1, 2, 4, 5/6 (850/1700/1900/2100 MHz)
3G (RFF91LW): Tri-band HSPA+ 1, 2, 5/6 (850/1900/2100 MHz)
4G Quad band LTE 2, 5, 4, 17 (700/850/1700/1900 MHz)

STL-100-4
2G Quad band GSM/EDGE (850/900/1800/1900 MHz)
3G Dual band CDMA Cell and PCS (800/1900 MHz) Dual band UMTS (900/2100 MHz)
4G LTE Band-13 (700 MHz)

I'm sorry for any inconvenience and if there are some spelling errors.

You should check with your cellular provider, anyway should avoid STL100-1 its slower and doesn't have LTE. Many providers post this data on their website, but you really need to dig for it.

Hello and sorry for the (Witch) instead of Which written on the title.
I'm using CLARO Argentina as cellular provider. Will ask them and as you say will dig for more info.

Thank you for the quick replay

Ok this is what I found :
Argentina is so far behind that all carrier only use 850/1900 MHz frequencies and BB user needs to have 1,2,5,6 Bands in their Phones. There is no LTE - 4G here in Argentina. Its embarrassing

The Z10 STL-100-3 (RFK121LW) I think marches my requirement.
3G Quad band HSPA+ 1, 2, 4, 5/6 (850/1700/1900/2100 MHz)

I hope to be right and when the time comes I will be the happiest person alive.
