When traveling for work to new locations I always made sure to have multiple connectivity and VPN options (including commercial VPNs with in-country PoPs). It’s amazing what will work and won’t because of a hotel or conference venue setting.

Also, always good to get a local SIM with a roaming data plan and hotspot support. You can get the SIM in U.S. (pricey) or when you land. Hotels can help with that. Forgot to do it once and got reamed by the home carrier and their ‘international travel’ plan, especially with SMS/MMS messaging.

Push notifications go over internet so that needs a data plan. I would also go through all unnecessary apps and disable pointless notifications before travel (I don’t need realtime baseball scores while traveling). For local activity, nice to download larger files like maps, music, ebooks, audiobooks, and hiking guides.

As others have said, be careful not to violate local data sovereignty rules. Also, some folks have had issues with electronics seizure when returning at U.S. ports-of-entry. May want to slim down what you take with you.

Some non-tech thing. Make sure you talk to your healthcare plan about international travel. Best to make sure you have coverage while traveling. Also, may want to install and set up WeChat and AliPay mobile apps and configure payment before heading over. Many places won’t take cash or ATM cards. Before bringing back souvenirs, make sure they’re OK. Liquor, agricultural products, and unlicensed electronics usually have restrictions.

Lastly, sure hope you all update rfc2549 to support Meshtastic 😬
