4G capabilities - LTE 1800, LTE 2300, LTE 2600
Many smartphones used in the Americas do not have UMTS 2100 band enabled and so you ended up in 2G/Edge or GPRS band/speed - which in the old days using Moto Q's or early WinMobile devices, were adequate for email, maps & light browsing (as least in HKG.) Traveling abroad, I carry a spare/backup phone with these frequencies to take advantage of better speed, paid or otherwise. Do you recall what network/carrier you're on ?? (smart/iphone5 or tablet ??) >> PCCW, 3's, or, Peoples/China Mobile, etc.
An inexpensive Moto G for Global GSM usage would be a good choice for access.
