For a digital nomad, internet access is not a convenience but the workplace itself, and a single point of failure can cost a day's income or a client. Apartment WiFi fails, coworking networks go down, and cafes throttle heavy users. Experienced nomads therefore build a connectivity stack with at least two independent sources, so that when one fails, work continues on the other without a scramble.

The first decision is between a dedicated portable hotspot device and phone tethering. A dedicated hotspot, such as a pocket router with its own battery, keeps your phone free, usually offers better antenna performance and battery life, and can serve several devices at once. Phone tethering costs nothing extra and works anywhere your phone has signal, but it drains the phone battery fast, heats the phone, and ties your calls to your work connection. Many nomads carry both: tethering for emergencies, a hotspot for daily use.

Choosing a hotspot device means checking bands and compatibility. A good travel hotspot supports many LTE bands, since different countries use different frequencies, and the latest models add 5G where networks support it. Unlocked devices are essential: a carrier-locked hotspot that only works on one network is useless abroad. Battery life of ten hours or more, USB-C charging and a simple management app are practical features worth prioritising over exotic extras.

SIM strategy is the second decision. Local prepaid SIMs are usually cheapest for stays of a month or more, offering generous data allowances at local prices, but they require a store visit, local registration in some countries, and a SIM swap each border crossing. Travel eSIMs, from providers like Airalo, Holafly and Mobimatter, activate digitally before arrival, cover many countries on one profile, and cost more per gigabyte. The smart pattern is an eSIM for arrival days and a local SIM for the longer stay.

Data needs vary by work type, and buying the right allowance saves money. Email and documents use little data, video calls use roughly 1 to 3 gigabytes per hour depending on quality, and cloud backups or large uploads can consume tens of gigabytes quickly. A video-heavy worker should budget at least 50 to 100 gigabytes a month across all sources, while a writer or designer may manage on far less. Monitor usage in the first week in a new location and adjust before the plan renews.

Backup planning deserves the same attention as the primary connection. Identify two nearby coworking spaces or cafes with reliable WiFi before you need them, keep a small data balance on a second SIM, and carry a short ethernet cable and a travel router for apartments where wired internet exists but WiFi is weak. For critical calls, test the backup connection in advance rather than discovering its problems mid-meeting.

Security is part of connectivity too. Public WiFi networks are convenient and risky, so use a reputable VPN on any shared network, keep your devices updated, and avoid accessing sensitive accounts on open hotspots without protection. A personal hotspot is inherently safer than cafe WiFi, which is another reason to carry one.

Connectivity is the nomad's rent: a cost of doing business that deserves a budget and a plan, not an afterthought. Build a stack of apartment WiFi, a portable hotspot, an eSIM for arrival and a known backup location, and the internet stops being a source of anxiety and becomes what it should be: invisible infrastructure that lets you work from anywhere. Test your full stack on a normal workday before any critical deadline, so a failure surfaces during routine work rather than during the call that matters most.
