Let me tell you the least glamorous truth about living internationally:

It’s not the flight deals that break you.
It’s not the language barrier.
It’s not even the “Where do I buy deodorant in Croatia?” moment.

It’s the day you’re sitting in an Airbnb with great lighting and terrible Wi-Fi, trying to:

  • receive a wire transfer from a client,

  • log into a bank that demands a text message to a number you “used to have,” and

  • open an email that says, “We mailed you a letter. Please respond within 10 days.”

That’s the moment you realize something important:

Long-term travel isn’t hard because you move a lot.
It’s hard because the world still expects you to have a stable identity.

So today we’re doing something useful. We’re building the three systems that separate seasoned nomads from stressed-out wanderers:

  1. Phones (data + a number that actually works for 2FA)

  2. Banking (money access without meltdowns)

  3. Mail (because paperwork never stops, even when you do)

None of this is sexy. All of it is freedom.

1) Phones: Data is easy. Keeping your number alive is the real game.

If you’re traveling long-term, your phone has two jobs:

Job #1: Give you data everywhere

Maps, WhatsApp, translation, ride apps, banking apps—your phone is your survival kit.

Job #2: Keep a “real” number alive for logins

Because banks and government services still think it’s 2006 and SMS is “security.”

Here’s how to win both.

The best modern setup: eSIM for data + a permanent number for 2FA

Option A: eSIM for travel data (fastest, easiest)

  • Great for moving frequently (EU one week, Balkans the next, LATAM after that).

  • You activate instantly—no tiny SIM tool, no kiosk, no “Please show passport” drama.

What to use it for: data only
What not to use it for: being your “main number” for logins

Why? Because eSIM data plans change. You top up. You switch regions. Sometimes you replace the eSIM. And your bank does not care that you’re “between SIMs.”

Keep your home number alive (even if you’re not using it)

You don’t need your home carrier plan to keep your number functioning for security codes. You need a strategy.

Best approaches:

  • Wi-Fi calling on your home SIM (if your carrier supports it)
    Works well if you keep your SIM active and rely on Wi-Fi abroad.

  • A digital number for stability (Google Voice / Skype Number where available)
    Useful if you need a consistent number that doesn’t depend on physical SIMs.

Important reality check:
Some banks and services don’t accept VOIP numbers for verification. That’s why a lot of experienced nomads keep:

  • one “real” home SIM alive (cheap plan, minimal usage)

  • plus eSIM data for wherever they are.

Should you buy local SIMs?

Yes—but only when it’s worth the hassle.

Rule of thumb:

  • Staying under 30 days? Use an eSIM and keep moving.

  • Staying 30+ days? Consider a local SIM, especially if:

    • local plans are dramatically cheaper,

    • you need local call minutes,

    • you want better coverage outside major cities.

Pro move: buy a local plan that has an app for top-ups so you’re not constantly hunting kiosks.

Dual SIM and dual-phone setups (the “I’m not getting locked out” tier)

If your phone supports it, the best travel setup is:

  • Home SIM (kept active, used for SMS / 2FA / calls when needed)

  • Travel eSIM (data everywhere)

  • Optional: local SIM if staying long-term in one country

If you want true redundancy (and a little peace):

  • Keep an older backup phone at home base or in luggage with essential apps already logged in (email, bank, password manager).
    If your primary phone dies or gets stolen, you’re not “starting from zero” in a foreign country.

2) Banking: The goal is simple—never be one glitch away from broke.

The biggest mistake nomads make is assuming money works globally the way it works at home.

It doesn’t.

Banks freeze accounts. Cards stop working. ATMs swallow plastic like it’s a hobby. And the “fraud protection” system treats you like a criminal for buying groceries in a country you literally told them you’re visiting.

So the goal is not “find the best card.”
The goal is build a banking stack.

The nomad banking stack (minimum viable version)

You want:

  • Two debit cards from different institutions

  • One credit card (ideally with no foreign transaction fees)

  • A multi-currency account to receive/send money cheaply

  • A backup card stored separately (not in the same wallet)

Because when something fails, you don’t want a “customer service journey.”
You want a button you can press that keeps your life moving.

Multi-currency accounts: how to get paid without losing money to fees

If you earn across borders—clients in USD, EUR, GBP, etc.—then you want the ability to:

  • hold multiple currencies,

  • convert at sane rates,

  • get paid with local account details,

  • spend without your bank panicking.

Services like Wise, Revolut, and Payoneer exist for exactly this reason.

Why they matter:

  • You can invoice a client in their currency.

  • You avoid stacked fees (client’s bank fee + your bank fee + conversion spread).

  • You reduce the “wire transfer anxiety” that hits at 2 a.m.

The #1 rule: Never rely on one bank, one card, or one app

Even “good” banks have bad days.

So keep:

  • one debit card in your wallet,

  • one in your luggage,

  • one credit card separate,

  • and emergency cash in a small amount (not all your money, just enough to survive a glitch).

ATMs: how to avoid the “this machine just ate my weekend” experience

Some ATMs are friendly. Some are hungry.

Basic rules:

  • Use ATMs attached to major banks (not random standalone machines).

  • Withdraw during daytime hours when a bank is open.

  • If the ATM offers “Convert to USD?” (or your home currency), decline and choose to be charged in local currency.
    That “helpful conversion” is often an expensive rate.

And yes—carry multiple cards because ATMs do sometimes swallow one.

Getting paid while abroad: invoice smart

If you’re working remotely:

  • invoice in your client’s currency whenever possible,

  • get paid through a system designed for cross-border flows,

  • convert only what you need for local spending.

This reduces fees and keeps your “base currency” strategy clean.

3) Mail: “Where is my package?” becomes a personality trait if you don’t fix this.

Mail is the silent killer of nomad life.

Because even if you’re fully digital, eventually you will need:

  • a replacement card,

  • a bank letter,

  • tax paperwork,

  • a notarized document,

  • a government notice,

  • or that one random envelope that says “Final reminder” even though it’s the first time you’ve seen it.

If you don’t have a system, you’re always reacting.

The best solution: a virtual mailbox with scanning + forwarding

Virtual mail services give you:

  • a real street address (not a PO box),

  • scanned images of incoming letters,

  • forwarding on demand.

That means you can see what arrived today even if you’re 6 time zones away.

How to use it properly:

  • Route all “important” mail there (banks, taxes, government, insurance).

  • Set rules for scans (open + scan junk? or only scan envelopes?).

  • Only forward physical mail when you actually need the original.

The “base camp” method: one trusted address + clear rules

If you have family or a trusted friend:

  • use their address as your permanent base,

  • but make sure they understand your rules.

That means:

  • Do not throw anything away

  • Text you photos of anything that looks official

  • Keep a “Nomad folder” so nothing disappears under a pile of coupons

This is simple—and it works—if your base camp person is reliable.

Packages: don’t ship to an Airbnb unless you’re staying long enough

Shipping internationally is a game of delays, customs holds, and wrong doorbells.

Safer options:

  • Amazon lockers (where available)

  • parcel pickup points

  • coworking spaces that accept packages

  • hotels (many will accept if you ask first)

Rule of thumb: ship packages only to places you’ll be in for at least two weeks, unless it’s an emergency.

And always use tracking.

Bonus: Build a “Nomad Identity System” (this is what makes everything smoother)

This is the meta-system that holds the whole thing together.

If you do nothing else, do these:

1) Use a password manager (non-negotiable)

1Password or Bitwarden.
Store:

  • logins,

  • backup codes,

  • passport scans,

  • residency documents,

  • insurance PDFs,

  • bank account details.

Because when you lose access, it’s never at a convenient time.

2) Create a “high-trust” email just for travel + finance

One email used only for:

  • banking,

  • travel services,

  • government portals,

  • identity verification.

Not your newsletter signup email. Not the one you used to download a free PDF in 2017.
Your clean email.

3) Backup your 2FA properly

Use an authenticator app where possible (more reliable than SMS), and save backup codes in your password manager.

SMS is still common—but it shouldn’t be your only lifeline.

The takeaway

Long-term travel isn’t about the perfect beach.
It’s about stability in motion.

When your phone works, your money flows, and your mail is handled… you stop feeling like you’re “surviving abroad” and start feeling like you live there.

These are the unglamorous systems that keep your life calm while everything else changes.

And honestly? That’s the real travel hack.
