Google's Fi mobile service now supports RCS, the standards-based rich messaging standard. Also today, the company announced that Fi overseas roaming in 33 countries (mostly in Europe) will now take advantage of faster 4G networks. The RCS standard offers rich services like typing indicators, read receipts, and hi-res videos. Fi users can take advantage of RCS simply by using Google's Messages as their default messaging app. Google Fi already offers data service —-albeit at slower 3G speeds —-in over 200 countries, with no special roaming charges.
