AT&T

Late last year saw AT&T adding international LTE roaming in Canada and the UK, and today they're adding 13 more nations to the list. If the added services are treated in the same way as AT&T's deals with EE in the UK and Rogers in Canada, the rates charged for the "Data Global" add-ons won't change with the addition of LTE services, though AT&T did not say if that would be the case in their press release. AT&T put a full list of the countries where you'll be able to get LTE speeds while roaming starting today:

Today, AT&T has expanded its international LTE footprint to now include Spain, France, Japan, South Korea, Australia, Hong Kong, Switzerland, Malaysia, Russia, Singapore, Guam, Hong Kong and Antigua & Barbuda. AT&T is committed to providing its customers a wider global footprint to enjoy LTE data speeds. In fact, AT&T currently has agreements to allow for LTE roaming in over 200 countries.

It's worth noting that there are still hurdles to getting LTE roaming working. AT&T and the LTE carriers in Canada use different LTE bands, so it may be hit or miss whether or not your specific phone will be able to roam onto LTE while abroad. Thankfully, modern smartphones are consolidating more and more LTE bands into single devices (manufacturing is just easier that way), so your chances are much higher if you have a fairly new phone.
