Stay Connected in Palo Alto

Palo Alto sits at the center of Silicon Valley, so you'd expect connectivity to be excellent, and mostly it is. LTE and 5G coverage blanket the city. Fibre runs to most hotels. Free WiFi is everywhere from University Avenue cafes to the Stanford campus. The frustrations are subtler. US carrier plans for short-term visitors tend to be expensive compared with what you're used to in Europe or Asia, and prepaid SIM activation can be slower than you'd expect for a tech hub. Travelers often get caught off guard by the cost of roaming on their home plan, only to discover that a US tourist eSIM bought before landing would have cost a fraction of the bill. The good news: in Palo Alto specifically, you're rarely more than a block from a strong signal or a cafe with usable WiFi, so getting it slightly wrong won't hurt you. Stakes are low.

The three national carriers all operate in Palo Alto with strong signal: Verizon, AT&T, and T-Mobile. Verizon tends to have the most consistent coverage across the wider Bay Area, including the hills above Stanford and out toward the coast. T-Mobile is generally the fastest in downtown Palo Alto and on University Avenue. 5G speeds comfortably handle video calls and large file uploads. AT&T sits between the two. It's a solid all-rounder, useful if you're moving between Palo Alto, San Francisco, and San Jose. 5G is widely available across all three carriers in central Palo Alto, the Stanford Shopping Center area, and along El Camino Real. Speeds on a decent 5G connection typically run fast enough for hotspot tethering and remote work, though you might get the occasional dropout on Caltrain rides up to the city. Indoor coverage in older Palo Alto buildings can be patchy, notably the Spanish Revival places near downtown. Any carrier. Fair warning.

Palo Alto has free WiFi everywhere. The Stanford campus, University Avenue cafes, the public library, and most hotels all offer it. Plentiful doesn't mean safe. Public networks at airports and busy cafes are a known target for credential harvesting and session hijacking, and travelers tend to be attractive marks because they're often logging into banking apps and corporate email from unfamiliar networks. A VPN like NordVPN encrypts your traffic between your device and the VPN server. Even if someone is snooping on the cafe network, they see scrambled data rather than your login details. It also helps when you need to access services back home that geo-block US IP addresses. Worth turning on automatically for any network you didn't set up yourself, notably at SFO and Palo Alto's busier downtown cafes.
