Travel eSIM vs local SIM: pros, cons & best choice

For ages, staying connected while traveling meant one thing: getting a local SIM card. It was the tried-and-true method, and for good reason – they offered solid service and were compatible with virtually any phone. But let’s be honest, they came with their own set of hassles. Think about it: hunting down a store after a long flight, dealing with language barriers and trying not to lose your home SIM card while you’re fumbling with a new one. They came with pros and cons, of course, but the rise of Travel eSIM technology has changed the game, providing a fully digital, stress-free alternative that’s quickly becoming the new standard. 

While both offer a way to avoid exorbitant roaming charges, they’re not created equal. In this article, we’ll dive into the pros and cons of both options and show you exactly why we think eSIMs are the better choice for your next trip.

Local SIM cards: The go-to for decades

First, let’s tackle the old-school favorite: local SIM cards.  

Pros 👍

  • Widespread compatibility – Most unlocked phones, even older models, can use a physical SIM card. 
  • Local phone number – A local SIM offers mobile services beyond internet access. This includes a phone number, which can be useful when navigating a new country. 
  • Better for long stays – If you’re staying in one country for a long period and need a lot of data, a local physical SIM is often the most cost-effective option. 

Cons 👎

  • Inconvenience – Probably the biggest drawback. You have to physically find a store, wait in line, and possibly deal with a language barrier. In some countries, you may even have to provide your passport or other personal information. 
  • Physical hassle – You have to physically swap out your home SIM card, risking it getting lost or damaged. If your phone doesn’t support dual SIMs, you also have to find a safe place to store your primary SIM so you don’t lose your signal when you get home.
  • Single-country use – While SIM cards are a great option for long periods of travel, they’re not so great if you move around a lot. A local SIM card is typically only valid in the country where it was purchased, making you repeat the process every time you cross a border. 
eSIM: The modern game-changer

Now, let’s talk about the eSIM – the digital SIM card that’s built right into your phone.

Pros 👍

  • Flexible & convenient – You can purchase and download an eSIM plan from anywhere in the world, before you even leave your home country. This means you land with immediate, ready-to-use connectivity. No lines, no stores, no stress. 
  • Multi-country plans – You are not limited by your phone’s physical SIM slots. If you know you move around a lot, you can purchase and install multiple eSIMs on your device, making travel seamless. Even better, you can purchase Regional or Global plans that allow you to travel seamlessly across multiple countries without ever having to switch plans or buy a new SIM. This is a massive time-saver for anyone travelling often and in multiple locations. 
  • Keep your primary number – With an eSIM, you can keep your primary number for receiving important calls and texts while using the eSIM for all your data needs, like maps and social media. This dual-SIM functionality is a lifeline for anyone who needs to stay reachable.

Cons 👎

  • Device compatibility – Not all smartphones support eSIM technology. While most newer models are compatible, it’s essential to check if your phone is eSIM-enabled and carrier unlocked before you purchase a plan.
  • Higher upfront cost – While prices are competitive, some eSIM plans can be slightly more expensive per gigabyte than a local SIM card, especially for long-term stays in one country. However, the price you pay for the convenience and flexibility is often well worth it. 
  • Data-only plans – Most travel eSIMs are currently data-only plans. If you need a local phone number for calls, a physical SIM might be a better choice.
Using a Travel eSIM or local SIM while traveling
The final verdict: Which is better for your trip?

The answer comes down to your travel style and priorities. 

Choose a local SIM if: 

  • Your phone is not eSIM compatible 
  • You’re staying in a single country for a month or more and rely on a local phone number 
  • You plan to use a lot of data for things like streaming or video calls 

Choose a travel eSIM if: 

  • You value convenience and flexibility above all else
  • You’re a frequent traveler or on a multi-country trip and want a single, seamless plan
  • You don’t rely on a local phone number and want to keep your primary phone number active 

While physical SIM cards are still a valid choice, especially for long stays, the benefits of an eSIM are hard to ignore. They save you time, eliminate stress, and offer a more secure and flexible way to stay connected, which is priceless when you’re on the road.

On your next trip, skip the line at the airport kiosk. Simply download an eSIM, and your adventure can begin the moment you land!
