If you don't mind sharing the details, what was your internet setup in a beach in Thailand?
4G enabled iPad mini + Panic's Prompt.app for iOS. It wasn't a regular thing, just resolving some access issues (on servers) for colleagues (at an all remote agency).
Having said that, I've also used a Thai 4G sim to tether (and allow colleagues to tether) for data while in Melbourne and while in California.
Using my laptop and occasionally iPad, I've worked from at least 4 different homes, a casino, 3 short term rental houses, a couple of client offices, and a beach in Thailand over the last ~7 years.
