Ask Slashdot: Do 4G World Phones Exist?
First time accepted submitter Viv Savage (3679171) writes "I live in the U.S. but my daughter will be attending college overseas next year (Scotland specifically). I need to purchase a new phone for her and I'm curious what the Slashdot community would recommend. I understand that a GSM world phone supporting 850/900/1800/1900 MHz frequencies would give her the best voice support. There doesn't appear to be a solution for getting high-speed data (i.e., 4G) here and abroad with one phone. Have any worldly Slashdotters figured this out?"
Yes, most new smartphones have this capability. Take the iPhone 5S for example. (https://www.apple.com/iphone/LTE/)
These are the supported LTE bands:
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)
700/AWS are the main 4G bands in the American ITU region
800/1800MHz are the main deployed bands in Europe/African ITU region
1800/2100MHz are the main deployed bands in the Asian/Pacific ITU region (note that APT 700MHz is different to the USA's mongrel of a 700MHz band)
Other bands (e.g. 900MHz) are only used very rarely (in this case one operator in Sweden and one in Czech Republic) but also are supported.
Your daughter's main problem will be:
a) whether her UK network has deployed 4G where she is (though in the middle of Edinburgh or Glasgow she should be fine). You will find that due to better 3G networks, Europe is lagging behind the US in 4G coverage.
b) the lack of 4G international roaming (not many operators let you roam onto 4G networks)
c) the cost of 4G international roaming (if allowed) would be prohibitive
And what 4G phones are fully waterproof? This is Scotland we're talking about.
Red to red, black to black. Switch it on, but stand well back.
