Tip 1 · Connectivity

Travel eSIM vs. local plans

Honestly, I always insist on taking the cheapest option and buying a local SIM card. My best SIM shopping experience ever: Helsinki, a small electronics store in a suburb. 20 euros for 30 days of true unlimited data; the owner greeted me with a cappuccino, and then we talked about outdoor camping for an hour.

Morocco was the exact opposite: four store visits, showing my passport, maxing out the translation app – and the card I bought ran out of data after three days.

For those who enjoy such stories, I still recommend buying a local SIM. If I stay somewhere longer, I definitely won't give that up myself either.

However, if I'm traveling for a shorter time or on business and don't have time for four store visits, it's convenient to turn on my phone on the runway and be online immediately. The eSIM market is huge – but at the latest when reading the fine print, I've often stumbled over the data-harvesting frenzy of some providers. Saily* acts differently here: The company belongs to Nord Security – the same company as NordVPN – and comes with corresponding privacy tools, including an integrated VPN. Sounds nerdy, but is actually relevant, especially in autocratically governed travel destinations.

Privacy is a matter of trust – it's best to check Saily's current privacy policy and terms and conditions yourself before you decide.

Häufige Fragen

What is the best travel eSIM?
My personal best experience was with Saily – fast setup, good coverage, and the company places significantly more value on privacy than most competitors. Other frequently mentioned options are Airalo and Holafly. Ultimately, it depends on your destination and your data volume.
Is Saily reputable?
Yes. Saily belongs to Nord Security GmbH, the same company behind NordVPN. The company is registered in Panama and has a no-logs policy. Nevertheless, I recommend: always check the current privacy policy and terms and conditions yourself before choosing a provider.
How can I continue to use WhatsApp with an eSIM?
Normally. WhatsApp is tied to your phone number, not to the SIM card. Since your physical SIM remains active for calls and SMS, absolutely nothing changes for WhatsApp.
Do I have to change my WhatsApp number with an eSIM?
No. The eSIM only takes over the data connection abroad. Your home number remains the same, and WhatsApp continues to run unchanged.

WISE – The perfect debit card for traveling

Another SIM adventure – this time from Brazil. I wanted to switch to a local plan after a few days of eSIM. After 20 minutes of passport checks and using a translation app in a telecom shop, I suddenly had to sign a contract.

I actually got WISE* because my traditional bank quietly and steadily increased their fees abroad over the years – foreign currency surcharge here, withdrawal fee there. WISE* does it differently: real mid-market exchange rate, no hidden markups, no subscription model. I see exactly what a transaction costs before I confirm.

Back to Brazil: In the WISE app, you can create a virtual card in seconds – own number, own expiration date, any limit. I used it for the contract, asked nicely when the first deduction would occur, and simply deleted the card shortly beforehand. Problem solved. The virtual card is useful anywhere you have to enter card details where you don't completely trust the recipient.

Get a free WISE credit card

Using my friend link, you can get the physical WISE debit card delivered for free (otherwise a one-time fee of ~€7) or transfer up to €500 once without fees.

Häufige Fragen

Which travel credit card is the best in 2026?
My personal tip is WISE – for three reasons: (1) Real mid-market rate without markup on every foreign currency payment. (2) Transparent fees without a subscription model. (3) Virtual disposable card for situations where you do not have to give card details to untrustworthy sources. If you need a traditional credit card with insurance benefits, you should look additionally – WISE does not fully replace that.
Does WISE offer a real credit card?
No. WISE offers a debit Mastercard, not a credit card. This means: no credit limit, no overdraft, no credit check required. Advantage: you can not spend more than what is on it. Disadvantage: some hotels and car rental companies require a real credit card for pre-authorizations – WISE sometimes does not get through there.
How much does the WISE credit card cost?
The physical WISE debit card is free via a friend link (otherwise a one-time fee of ~€7). Account management is free. You can withdraw up to a certain amount per month without fees using the card – after that, a small fee applies.
Who is behind Wise?
WISE PLC is a British fintech company, founded in 2011, listed on the London Stock Exchange since 2021. The company is regulated by the UK Financial Conduct Authority (FCA) and has over 16 million customers worldwide.
Is WISE reputable?
Yes. WISE is regulated (FCA in the UK, BaFin equivalents in other markets), publicly traded, and one of the largest international payment providers. Your deposits are kept separate from company funds.

Tip 3 · Memories

Surprise: my favorite hack is postcards

I am constantly on the go and my family and friends at home often miss out. For a long time, postcards were my way to make up for that – and with real effort: looking for authentic cards locally, finding the right stamps, and then hoping the card actually arrives. The more love I put into the search, the more disappointing it was when it didn't arrive.

Online postcard services sound like the logical alternative. The problem: I didn't find one that really gives me full control. Most print their own note on the card, some even force a QR code on you to enable a digital reply to your analog message. That pretty much ruins the charm of a real postcard.

So I built slickpostcard.com myself. No app, no registration, no credit system – and most importantly: full control over the front and back without third-party advertising. Upload a photo, write text, enter address, pay, done. As easy as a WhatsApp, but it stays.

Häufige Fragen

Best online postcard service in 2026?
If you want it simple, slickpostcard.com offers the most uncomplicated way to send your postcard online without advertising on the card, without registration, without a credit system. Competitors like mypostcard.com or simplycards.com are solid alternatives if you do not mind a bit of branding on the card and need even more options and templates.
mypostcard.com or simplycards.com – which is better?
Both are established services and have been on the market longer than slickpostcard.com. Both require registration and print their own design elements or branding on the card. If you do not mind that, they are solid options. If you want a completely ad-free card without an account, try slickpostcard.com.
Are there online postcards without branding or advertising?
Yes – slickpostcard.com. You have full control over the front and back, no service logo, no QR code, no forced design. That was the main reason why I built it.

Tip 4 · MacGyver-Kit

Duct Tape & real travel hacks

No product, no affiliate link – just a tip from personal experience.

In the Langtang region in Nepal, after a long trekking day in a small mountain hut between two passes: Upon arrival, there was a heated discussion around an old tube TV. A guide explained to me that the satellite dish outside was broken – and with it, the evening Bollywood movie for the whole hut was canceled. Honestly, not bad news; those movies had already brought me close to delirium on 12-hour bus rides. But I couldn't resist the proud use of my tapes. Twenty minutes later, everything was running again.

Tanzania, in the middle of the Serengeti: Our old Toyota Land Cruiser broke down – an electrical problem, a loose connection, no spare part far and wide. You know how it is.

Wrapping a meter of duct tape around a lighter costs no space and no weight. Here are a few more hacks that really take up no room in your luggage:

  • Duct Tape – wrapped around a lighter (classic duct tape, ~50 cm is enough)
  • Cable ties – ideally in different sizes
  • Lighter – allowed in carry-on luggage (max. one lighter, no spare fuel), forbidden in checked baggage
  • Pocket knife – only in checked baggage, don't forget before heading to the gate
  • Sewing kit – thread, needle, two buttons. Has saved my pants more than once
