Best SIM Cards & eSIMs for Digital Nomads (2026)

Thailand (DTAC/True), Vietnam (Viettel), Malaysia (Maxis/Celcom) — local SIMs give you 30–100 GB for $5–$15. Buy at the airport or any 7-Eleven. Keep an Airalo plan as backup for border crossings.

Best option: Local SIM + Airalo regional backup

Any EU SIM works across all 27 EU member states at domestic rates (roaming abolished 2017). Get a cheap German, French, or Spanish SIM — it roams everywhere. For non-EU countries (Serbia, Georgia, Albania), use Airalo country-specific plans.

Best option: EU SIM (roams free) + Airalo for non-EU countries

Mexico and Colombia have excellent local SIMs (Telcel, Movistar, Claro). Brazil's local SIM setup can be slow if you lack a CPF (tax ID). For shorter stays or multi-country trips, Airalo's regional plans cover most of the continent.

Best option: Local SIM for 30+ day stays, Airalo for shorter trips

UAE (du/Etisalat), South Africa (Vodacom), Kenya (Safaricom) all have excellent local SIM options at very competitive prices. eSIM coverage is improving but local SIMs are still usually cheaper and faster for extended stays.

Best option: Local SIM for most countries

Most eSIMs and foreign SIMs do not work in China on the regular internet. You need either a China SIM (China Mobile, China Unicom) for local access, OR a foreign SIM with active VPN before entering. China Mobile HK sells SIMs that work in China with unblocked access. Set up your VPN before you arrive.

Best option: China Mobile HK SIM + VPN set up before arrival

What is an eSIM and which phones support it?

An eSIM (embedded SIM) is a digital SIM that is built into your phone — no physical card required. You download a carrier profile via QR code or app and activate it instantly. Most flagship phones from 2019 onward support eSIM: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Some budget Android phones do not have eSIM. Check your specific phone model — go to Settings > Cellular/Mobile > Add eSIM and see if the option appears. Note: if you bought your phone locked to a carrier, it may need to be unlocked before eSIM from other providers works.

Should I use an eSIM or buy a local SIM?

For stays under 2 weeks or multi-country trips: eSIM wins. Instant setup, no SIM hunting on arrival, switch between plans easily. For stays of 1 month or more in a single country: local SIM almost always wins on price. A Thai local SIM with 50 GB costs $8–12. An Airalo plan for the same data would cost $15–25. The convenience premium of eSIM is worth it short-term; the price penalty hurts long-term. Practical strategy: use eSIM to get connected at the airport, then buy a local SIM once you are settled.

Do eSIM plans include phone calls and SMS?

Most travel eSIM plans are data-only — they do not include a local phone number, inbound calls, or SMS. This is fine for most nomads who use WhatsApp, Signal, Telegram, or Google Voice for calls and messages. If you need a local number — for two-factor authentication, banking SMS, or local calls — you need either a local SIM or an eSIM provider that includes voice (some Holafly plans include WhatsApp calling). Important: two-factor authentication SMS codes from your home country bank may not work on a foreign number. Keep your home country number alive with a cheap plan if your bank requires SMS 2FA.

How much data do I actually need per month?

For most remote work in cafés and apartments with WiFi, you need less mobile data than you think — your phone fills gaps between WiFi connections. A rough guide: 2–5 GB/month if you are always in places with WiFi and only use mobile data for navigation, messaging, and brief browsing. 10–20 GB/month if you use mobile data as a primary connection, make video calls on the go, or work from outdoor locations. 30+ GB/month if you tether your laptop from your phone or work from locations without WiFi regularly. Most Southeast Asian local SIMs offer 30–100 GB for under $15, making data anxiety largely a non-issue in that region.

What happens to my home country phone number while abroad?

If you put a foreign SIM in your phone, your home country number goes offline — you cannot receive calls or SMS on it. Options to keep your home number alive: (1) Keep your home SIM active on the cheapest possible plan and use a dual-SIM phone with your travel eSIM as the data line. (2) Port your home number to Google Voice ($20 one-time) which receives calls and SMS over the internet — works anywhere with data. (3) Use a virtual number service like Hushed or Skype Number. Keeping a US number active matters most for: banking SMS 2FA, government services, and any US accounts that require a US phone number.
