I did a bunch of traveling earlier this year and getting local SIM card is pretty easy and cheap (~$20/mo), and has the advantage of allowing local calls. In Bangkok and Kyiv you can get them at any 7-11 or electronics store. Philippines and Prague it was a visit to a carrier. The rough patch was Tokyo, but you can rent a mobile hotspot for a reasonable amount and have it delivered to the airport.
If you're only there for a few days, free roaming is very nice to have, but if you're there a week or more I think it's worth the small effort to get the local SIM. That also allows me to keep Straight Talk prepaid in the US with my own phone. YMMV, but this was the most economical, flexible route for me.
