4G LTE bands in Singapore and USA

Do note that Singapore LTE networks mostly use bands 3 and 7.

Operator	Frequency (MHz)	Band
M1/Singtel	1800/2600	3 & 7
Starhub	1800	3

Buying a 4G Nexus 7 '2' from the US would mean that there's a risk that you can't use LTE here (3G HSDPA will work fine however...). European models are preferable.

For the equivalent iPad Mini with Retina, do purchase the model that supports the most LTE bands as shown in the table I've compiled below.

Refer to this link here on Apple's website for the latest updated models with LTE support for iPads.

Nexus 7	North America	700/750/850/1700/1800/1900/2100 MHZ (Bands: 1/2/3/4/5/13/17)
