Airalo eSIM (our top recommendation)
Things have changed a lot since we first started traveling (thankfully!). It’s actually easier (& cheaper!) than you might think to get cell service when you’re traveling outside your home country.
Enter: Airalo!
Airalo is an app and online marketplace that sells international eSIMs.
An eSIM is a digital version of a physical SIM card (the ‘e’ in eSIM stands for embedded), allowing you to activate a new cellular plan without having to take out or insert a physical SIM card into your phone.
Many newer smartphones have the capability to support multiple SIM cards at once, making it possible to download and use an eSIM along with your home SIM.
Tip: A simple Google search will tell you if the model of your phone is compatible with an eSIM.
The eSIMs connect to local networks and Airalo offers local, regional, and global (international) eSIM options. Read more on the local and regional options below.
- Local eSIM: exclusive to a single country
- Regional eSIM: specific region (like Europe or Asia)
- Global eSIM: covers 87 countries around the world
Each tier of eSIM options have a variety of different data amounts and price points. The cost will vary depending on the location. Airalo also makes it very easy to add more data to your plan if you need to top yours off.
Pros
- it’s cheap!
- it connects you to local cell towers & we’ve always had great connectivity for data
- seamless to use once you install
- if you run out of data, you can easily “top up”
Cons
- you can’t make phone calls or use SMS texting (it is just cellular data)
- can be a little confusing to install your first time (though they have made it easier!)
- some locations are a bit more expensive*
*There are a few locations where we’ve found the cost of Airalo data is much higher than the cost of purchasing a local SIM card. Mexico is the country with the greatest discrepancy we’ve found; Airalo data is about 2x the cost of a local SIM for a months worth of data.
How to use Airalo
You can purchase Airalo eSIMs directly from the free Airalo app or online.
The app is very streamlined, so you can browse eSIMs, purchase/activate new eSIMs, and archive old ones straight from your phone. Most eSIMs have an automatic install, which makes the process super quick and easy!
It’s also worth noting that Airalo isn’t compatible with ALL devices, but they cover a wide range of brands and cellphone types. View a list of compatible devices here.
Our experience using Airalo
We’ve been using Airalo almost exclusively for international travel since we discovered the app in summer 2022 and we have found it to be extremely convenient and reliable. We typically buy local eSIMs, instead of global, but there have been a few cases we used a regional eSIM (for Europe) and it worked really well.
As full-time travel bloggers, we work while traveling. I am constantly uploading videos to Instagram, staying in touch with our TWS team, and making notes in Google Docs. This means we need good cell coverage on our travels. (And that doesn’t even cover the “normal” travel things like navigating Google Maps.) Even with our “high maintenance” needs, we’ve had really great experiences with eSIMs.
It’s not always quite as cheap as buying a local SIM card in the country. However, the extra cost isn’t usually much more than a few dollars and the convenience of being able to connect immediately when you touch down in a new county is so worth it.
The alternative would be relying on the internet until you are able to get to a convenience store or cell provider store in-country…. Which is not always easy to navigate if you don’t have data!
International SIM card
An International SIM card is a SIM card you can use worldwide. It connects you to a global network where you can communicate with both domestic and international phone numbers while traveling.
International SIM cards typically cover 100+ countries around the world.
These can save you a ton of money and time, especially if you’re on a trip visiting multiple countries. Do note though, not all international SIM cards are created equal, which we’ll touch on further down in this guide!
How to use an international SIM Card
Installing an international SIM card is a fairly simple process. You just have to swap out your home SIM card with the international one.
Many of them come as a 3-in-1 size so they will fit into most phones.
However, it’s important to note that not all phones are compatible with an international SIM.
Is your phone compatible with an international SIM?
Before you commit to using an international SIM card, you need to make sure your phone is unlocked and compatible.
To check if your phone is unlocked, you can call your network provider or visit a store to double check and get help unlocking it. Generally, the employees are happy to get this done and it doesn’t take long to do.
If you are using iOS, you can check in your settings:
- Go to Settings > General > About, then scroll down a bit til you see “Carrier Lock”. If it reads “SIM locked”, you’ll need to call your network to iron that out. Otherwise, if it reads “No SIM restrictions”, you’re good to go!
You can also purchase an international SIM card to use in a personal wifi device or put in your ipad or tablet for internet access aboard.
Where can I buy an international SIM card?
The only way to purchase an international SIM card is online through a third-party.
A quick search will give you an overwhelming amount of options, so we’ve broken down some of the best ones below to make it easier for your search.

Data only vs talk & text
International SIM cards come in two different styles, and it’s important to know what you’re buying because it’s a moderate difference depending on your travel style.
- Data only: No local number, calls, or texts. ONLY a connection to a network.
- Talk & text: Provides you with a local number, calling/sending SMS locally is an option.
With data only, you’ll likely rely on apps like WhatsApp or Facebook Messenger to communicate, but the benefit of having talk and text is that you can call ahead to make reservations or contact your hotel concierge.
Pros
- can get set up before you leave for your trip
- great for multi-destination trips
- can be used in your personal wifi device or tablet
Cons
- need a physical SIM tray to use in your phone
- data isn’t always the best connection available
Local SIM card (cheapest option)
Purchasing a local SIM card is one of the original, tried-and-true ways to stay connected. They’re very popular and offered in most countries around the world.
This is going to be your absolute cheapest option for getting connected to data abroad.
Local SIM cards give you access to the best rates and local deals, as well as give you a domestic number so you can make local calls and texts.
Always do research before you leave to ensure it’s an option in your destination as (in rare cases) some countries don’t allow foreigners to use local SIMs.
They’re usually sold at International airports (more expensive) and convenience stores around the world. Make sure you’re buying from an authentic shop and not a reseller to avoid getting scammed or a faulty SIM.
Otherwise, you can buy a prepaid local SIM online and activate it once you land in your destination.
The price of the local SIM varies depending on the country, but it can be extremely cheap (as low as $5/month in some places in SE Asia).
What you need to get a local SIM abroad:
- Passport
- Unlocked phone
- Local address (sometimes – you can use the address of your accommodation)
- Passport photos (rarely)
Pros
- cheapest option for data abroad
- option to get local number to make phone calls and texts
Cons
- you cannot purchase until you’re in your destination
- need a physical SIM tray to use in your phone
- some countries require you to sign a contract for a phone plan (this is rare – and often can be short term)
Tips for getting a local SIM card
- Make sure you have an unlocked phone before you leave the country. You can ask your cell provider at home if the phone is unlocked and able to support a different SIM card temporarily.
- Ensure your SIM works before you leave the shop. You’re generally safe if you bought your SIM from a reputable shop, but it’s always good practice to double check.
- Note your local number. Add it to your notes app or write it down somewhere safe incase you need it later.
- Hold onto your old SIM card until you return home. It’s best if you can keep it in a safe place where it won’t get lost. Oftentimes the shop you purchased the new SIM from will tape your old SIM to the card the new SIM came with so you can store it securely in your wallet.
International data plan (US-based & most expensive)
If you’re traveling from the U.S., your local network provider likely has an international plan you can activate once you arrive abroad.
They’re not the most cost effective, but they could be a viable option if you don’t want to go through the SIM card process and don’t mind spending the extra money.
Depending on your provider, you’ll need to look up specific plans and activation instructions. For most, you’ll receive a text once you land and turn off airplane mode, then reply with a simple ‘yes’ to activate the plan automatically.
If you’re traveling to Mexico or Canada, your home phone plan may already include these countries, so double check and you could save a bit of money.
It’s also worth mentioning that although you’ll have coverage in your destination, it doesn’t necessarily mean it’ll be the best coverage. Oftentimes you’ll have a limited amount of data at at normal with a high-speed connection and they will bump your connection speed way down once what limit is exceeded.
While you’re looking into plans with your provider, be sure to check the data speeds so you don’t arrive with any surprises.
Below we’ve broken down some of the most popular international phone plans with U.S. network providers:
T-Mobile
- Magenta Plan: This plan includes unlimited texting and data (at up to 256 Kbps) in over 210 countries and destinations. Calls from these countries are billed at $0.25 per minute.

Pros
- don’t need to install anything
- you can text and call as you normally would
- this may already be an option in your current plan
Cons
- depending on how often you travel abroad, a plan with international coverage may or may not make sense
- pay-per-day fees can add up fast – this is usually the most expensive option for data
- once you reach your data limit, you will be throttled to 2G speeds
Helpful tips for using your phone internationally
Use these tips to make a seamless transition when staying connected internationally.
- Pack a quality battery pack. You’ll be using your phone a ton to pull up maps and different information. We’ve found a portable battery especially useful on long day trips when we don’t have access to outlets. This is one of our travel essentials we never leave home without!
- Download apps and maps before you go. Especially apps like Whatsapp, Uber and Uber Eats as these apps will require you to verify your account by sending an SMS text message when you set it up. If you don’t have your home SIM card installed and working (abroad), you will have a much harder time setting up an account.
- Plus, you don’t want to get stuck in spotty service or wifi waiting for something important to download.
- Screenshot bookings, tours, and confirmations. If there is something you’ll need to access while offline (maybe from your email or an app), take a screen capture so you can pull up the information offline later.
- Manage data usage. Each SIM has a limit to how much data you can use, and you’ll be surprised how fast it can add up. Keep a close eye on your data usage so you don’t run out!
- Turn off cellular data/roaming and use airplane mode to prevent unwanted data usage. You can also shut off background app refresh for that extra oomph.
- Backup your data to a cloud server. It’s possible your phone could get lost, stolen, or broken while you’re away. To avoid losing years of memories, make sure everything is backed up to a cloud server, like iCloud, Google Drive, or Dropbox.
- Download WhatsApp. This is a very popular messaging app for communicating all over the world. It uses extremely minimal data and works as long as you’re connected to wifi or data.
