What is the technical difference between model A1457 and model A1530?
The EMEA version of the iphone 5s and the APAC version have different names and as it appears a slightly different spec:
- Modell A1457: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz), GSM/EDGE (850, 900, 1800, 1900 MHz), LTE (bands 1, 2, 3, 5, 7, 8, 20)
- Modell A1530*: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz), GSM/EDGE (850, 900, 1800, 1900 MHz), FDD-LTE (bands 1, 2, 3, 5, 7, 8, 20), TD-LTE (bands 38, 39, 40)
If this is correct the APAC model does the same what the EMEA model does, plus three TD-LTE bands. This important for world travellers.
Does this mean the APAC model is better for the same price and has another (better) LTE chip inside?
The same applies for 2 different US versions:
model 1533 does
1 (2100 MHz)
2 (1900 MHz)
3 (1800 MHz)
4 (AWS)
5 (850 MHz)
8 (900 MHz)
13 (700c MHz)
17 (700b MHz)
19 (800 MHz)
20 (800 DD)
25 (1900 MHz)
while model 1453 does
1 (2100 MHz)
2 (1900 MHz)
3 (1800 MHz)
4 (AWS)
5 (850 MHz)
8 (900 MHz)
13 (700c MHz)
17 (700b MHz)
18 (800 MHz)
19 (800 MHz)
20 (800 DD)
25 (1900 MHz)
26 (800 MHz)
The question is: Is this only marketing and all models are technically the same (i.e. model 1457 also does the three TD-LTE bands and model 1533 also does bands 18 and 26) or is there really a different chip inside?
If so, why buy the limited versions?
