When traveling internationally, staying connected often requires a bit of planning. One solution a lot of travelers consider is an international SIM card. But do you really need one? Let’s dive into the pros, cons, and alternatives to help you decide.

Before we break down whether you need one, let’s clarify what an international SIM card actually is.

A SIM card (Subscriber Identity Module) is a small chip that lets your phone connect to a mobile network. An international SIM card works across multiple countries, often allowing you to use your phone as if you were back home without racking up sky-high roaming fees. These SIM cards are typically offered by third-party companies and cover a range of countries, making them a popular option for globetrotters.

Why consider an international SIM card?

Here are some reasons why travelers opt for international SIM cards:

  1. Cost savings. Using your home carrier’s roaming services can be outrageously expensive, especially for data. International SIM cards offer more affordable rates for calls, texts, and internet usage, potentially saving you hundreds of dollars on your trip.
  2. Convenience. Many international SIM cards are designed to work in multiple countries without requiring constant swaps. This is particularly useful for multi-destination trips where juggling multiple local SIMs can be cumbersome.
  3. Ease of use. Once you insert an international SIM card into your phone, it usually works immediately. No need to search for Wi-Fi or hunt down a local SIM vendor as soon as you land.
  4. Reliable network coverage. Most international SIM cards connect to well-established local networks, ensuring strong coverage in the countries you visit.

Downsides of using an international SIM card

While international SIM cards can be helpful, they’re not without drawbacks. Here are some things to keep in mind:

  • Initial cost. Many international SIM cards have an upfront purchase price, which can be higher than a local SIM. Additionally, you may need to pre-load credit, so there’s an initial investment.
  • Limited data. Some international SIM cards come with data caps or slower speeds once you exceed a certain limit. This can be frustrating if you rely on your phone for navigation or streaming.
  • Complexity with dual-SIM phones. If you use a dual-SIM phone, you might face compatibility issues or confusion switching between networks.
  • Local SIMs may be cheaper. In many countries, buying a local SIM card can be a more cost-effective option. Local SIMs often come with generous data packages and better rates for in-country communication.

Alternatives to international SIM cards

If an international SIM card doesn’t sound like the right fit, there are other ways to stay connected while traveling:

  1. Roaming plans from your carrier. Some carriers offer international roaming plans at a flat rate. These plans might not be as cheap as international SIM cards, but they save you the hassle of switching SIMs.
  2. Local SIM cards. For travelers staying in one country for an extended period, buying a local SIM card upon arrival is often the best option. It’s usually cheaper and offers better data speeds.
  3. Portable Wi-Fi hotspots. Renting or purchasing a portable Wi-Fi device is another way to access the internet on the go. These devices can connect multiple gadgets, making them ideal for families or groups.
  4. eSIMs. If you have a newer smartphone, you might be able to use an eSIM (embedded SIM). eSIMs let you download a digital SIM card for international travel, eliminating the need for physical cards.
  5. Relying on Wi-Fi: If your phone usage is minimal, you can skip SIM cards altogether and rely on free Wi-Fi at hotels, cafés, and airports. Apps like WhatsApp and Skype allow you to make calls over the internet.

How to choose an international SIM card

If you’ve decided that an international SIM card is the right choice, here are a few tips to ensure you get the best one for your needs:

  • Check coverage. Make sure the SIM card supports the countries you’re visiting. Some cards focus on Europe, while others cater to Asia or global travel.
  • Look at data rates. Compare the cost of data packages and whether the speeds meet your needs. Read the fine print to avoid surprises like throttled speeds after a certain usage.
  • Read reviews. Research reviews from other travelers to get an idea of reliability and customer service.
  • Check compatibility. Ensure your phone is unlocked and compatible with the SIM card. Locked phones won’t work with international SIMs.
  • Consider customer support. Opt for a provider with accessible customer support in case you encounter issues while abroad.

So, do you need an international SIM card?

The answer depends on your unique needs. If you’re hopping between multiple countries and want seamless, affordable service, an international SIM card is a great solution. However, if you’re staying in one destination or prefer to minimize expenses, a local SIM or alternative like Wi-Fi may be a better choice.

10 road trip podcasts to keep you entertained for miles
These podcasts make the journey as fun as the destination
Personal perspective of person driving on mountain road

There’s nothing like the open road, windows down, snacks in the console, and a killer podcast playing in the background. And a good road trip podcast can make the miles fly by. Did you know that, according to a recent survey, podcasts reach about 53 percent of American adults every month? Personally, I never leave for a road trip without a curated queue of episodes – true crime for when I need a thrill, comedy when the energy dips, and storytelling when I want to sink into something immersive. So if you're looking for something new to press play on, your new favorite podcast might just be waiting for you.
Best road trip podcasts

Here are 10 road trip podcasts I’ve loved (and sometimes binged in one sitting) that are worth adding to your playlist.
1. SmartLess
If you haven’t already hopped on the SmartLess train, consider this your sign. Hosted by Jason Bateman, Sean Hayes, and Will Arnett, this podcast feels like eavesdropping on three hilarious friends as they interview big-name guests without ever taking themselves too seriously. I listened to five episodes straight while driving through Utah, and honestly, it made the flat stretches feel like a comedy club on wheels.
2. Criminal
There’s something weirdly soothing about Phoebe Judge’s voice, even when she’s telling you about art theft, missing persons, or strange legal loopholes. Criminal is for anyone who wants true crime that’s more thoughtful than sensational. It's one of those shows that makes you go, “Wait, THAT happened?”
3. This American Life
A road trip classic. Every episode of This American Life is a beautifully crafted story (or set of stories) about real people, sometimes moving, sometimes hilarious, always deeply human. 
4. Stuff You Should Know
If you’re traveling with someone who loves random trivia or deep dives into oddly specific topics (hello, history of vending machines), Stuff You Should Know is gold. It’s conversational, quirky, and educational without trying too hard.
5. Normal Gossip
This podcast dishes out anonymous, everyday drama like your funniest friend whispering secrets in the passenger seat. Think “someone’s ex got too involved in a neighborhood Facebook group” or “there’s beef in a local kickball league.” It's juicy and delightful, especially when you want something lighter.
6. Song Exploder
For music lovers, Song Exploder is like pulling back the curtain on your favorite songs. Artists break down their process and inspiration, piece by piece. I played an episode featuring Fleetwood Mac on a rainy drive through the Smoky Mountains, it was moody perfection.
7. The Moth
Real people, real stories, told live. The Moth is packed with raw, powerful, often funny tales that are perfect for long stretches of highway. 
8. You’re Wrong About
Ever wondered if everything you learned about Y2K, the McDonald’s hot coffee lawsuit, or Anna Nicole Smith was wrong? This podcast revisits misunderstood moments in pop culture and history with humor and heart. 
9. Radiolab
If you're into science, philosophy, or the mysteries of the universe, Radiolab is endlessly fascinating. It takes big ideas and makes them digestible, and even emotional. I’ve gotten so wrapped up in an episode before, I missed my highway exit.
10. Office Ladies
For The Office fans, this re-watch podcast by Jenna Fischer and Angela Kinsey is basically a road trip hangout. It’s warm, funny, and full of behind-the-scenes stories that feel like a cozy reunion with old friends.

Mexico just added a tax for cruise passengers: What it means for your trip
Visiting Mexico by cruise ship? You'll soon have to pay up
Carnival Cruise ship

Cruise passengers heading to Mexico will soon be paying a little more. Starting July 1, 2025, the Mexican government will implement a new head tax for travelers arriving at the country’s ports by cruise ship. The initial fee is set at $5 per person and will apply to all cruise guests entering Mexico, a move that comes as part of a broader agreement between the cruise industry and Mexican officials.

Mexico is one of the world’s most popular cruise destinations, with hotspots like Cozumel drawing millions of travelers annually. The new tax replaces a previously proposed $42 fee that was originally scheduled to go into effect this summer. After pushback from cruise lines and tourism advocates, a compromise was reached, resulting in a more gradual rollout of smaller fees.
