I am trying to solve this also.

I think that the Euro Version with the Exynos does not have the proper LTE Bands for North America LTE.

But the Qualcomm version does, though not sure about
TMobile.

I am looking at this from Canada GSM for $ 549. Factory Unlocked with following Bands:
2G Network GSM 850 / 900 / 1800 / 1900

3G Network HSDPA 850 / 900 / 1900 / 2100

4G & LTE 2100, 1900, 1800, 1700, 2600, 700, 850

Obviously for AT&T you just buy theirs.

I have read that the EXYNOS versions do not function in North America on LTE.

With all phones it seems that you must be very very
Specific about Model Numbers including Suffixes etc.

Especially SAMSUNG loves to make 24 versions of ALPHA, 50 versions of S4 etc.

Frequency Bands are a real WTF for amateurs like me:

For example are there TWO DIFFERENT 1700 bands, one for4G LTE and one for 3G , HSPA + or are they the SAME BAND with dual usage ?

In example ABOVE the Alpha Factory Unlocked Canada GSM @$ 549.

IF used for TMobile the LTE Bands look fine, but the 3G
1700 Band is not there. Will 3G merely use the 1700 LTE
band or does the SOC ( QUALCOMM) need to have
allocated the 1700 band for dual usage LTE and.3G
?
