What are the best shoulder season destinations with good Wi‑Fi and data?

Some of the best shoulder season destinations with strong connectivity are European and Asian cities that have invested in digital infrastructure. In spring (April–June), cities like Lisbon, Barcelona, Athens, and Istanbul offer mild weather, fewer crowds than summer, and generally solid Wi‑Fi plus excellent 4G/5G coverage for eSIM users. In autumn (September–November), places like Berlin, Prague, Budapest, and Seoul are great bases for remote work, with plenty of co-working spaces and reliable networks. For each destination, you can boost reliability by using a local or regional eSIM for primary data, treating café and hotel Wi‑Fi as a bonus rather than your only option. This combination gives you the flexibility to work from apartments, parks, or trains without hunting constantly for a strong Wi‑Fi signal.
