Will My Phone Work Abroad?

Luckily with the globalized world we are in now, there is a lot in place to make it easier for us to stay connected. This makes it easier to switch phone plans to fit where you are. 

However, there are some key definitions and things to understand to navigate the confusing language that phone carriers use so that you can pick among the best international phone plans for you!

Phone Plan Basics

A phone plan is a general term for the essential services of the phone, offering calls & texts, and/or data. They are not synonymous and one may be much more important than the other! 

It’s essential to know what services you need while traveling so you can get the right phone plan for you.

Almost every phone plan comes with a call & text plan, which is the allotment of minutes you can spend talking on the phone and the number of messages that can be sent and received within a specific time. 

However, this is not included in every travel phone plan, and almost always has limitations on international calls and messaging.

The data plan is set in terms of gigabytes (GB) for some time (10 GB/30 days) or it can be unlimited so you can connect without any limits! This is what connects you to the internet and allows the use of Google Maps, searching on a web browser, and using social media platforms. 

If a phone plan doesn’t include a data plan, then it can only connect to the Internet via WiFi (and hotspots). While Wi-Fi is great to stay connected and cut down on data plan costs, be sure to stay protected with a VPN for travel.

Mobile Technology - CDMA vs. GSM

When mobile communication was created and widely used in the 1980s, there were different technologies that dominated the industry, including CDMA and GSM. This is essentially the way that cellular devices (phones) communicate to get an internet connection- or frequency bands – associated with the second and third generation (2G and 3G). So, when your phone is on 3G data, it is either using CDMA or GSM technology.

CDMA phones can connect to CDMA networks, and GSM phones can connect to GSM networks. We can leave the specifics of how that communication works up to the engineers, and just go over which carriers use which communication technology.

Since the technologies are different, they aren’t always interchangeable. It’s important to know which technology your phone uses, and where that will and will not work. Newer devices are capable of working on both, so this shouldn’t be a concern for too many people unless your phone is older.

Unlock Phone

Many phone carriers “lock” a user’s phone so that it cannot be switched to another carrier. For example, if you purchase a phone with AT&T, it is ‘locked’ to the AT&T company for 60 days after purchase. This becomes a major barrier in switching phone plans while traveling but can be dealt with with a few steps. 

Historically, unlocking a phone while still under contract would have voided the contract, but most carriers have gotten away from this so you can take control of where you can use your phone, and with what company. Many companies sell their phones unlocked! The process depends on the carrier, and further guidance can be found from the experts here

*You cannot move forward with any of the international phone plans until your phone is unlocked!

International Phone Plans

Many providers offer international coverage, which may include the areas you’re traveling to. For example, many phone plans in Europe include coverage within the EU, and phone plans in the US often include coverage in Mexico and Canada. You should look at your current plan’s coverage to see what is offered because it might already be the solution you’re looking for! 

It is important to note that these international phone plans often limit you in data usage at 4G/5G rates, and then kick you down to 2G/3G. With everything, read the fine print to know what this is going to look like while in use, and understand if it will meet your needs!

When traveling outside of the regular coverage areas, many domestic phone plans have International Plans made for use while traveling. This is usually a daily fee for a certain amount of minutes/texts and data usage.

While this is a very convenient option, it can get ridiculously expensive, especially if you’re traveling for more than a few days. Keep exploring the best international phone plans that fit into your travel budget.

For example, in the US I used Verizon, which has international phone plans known as ‘Travel Pass’, where I could essentially have the same benefits of my plans at home anywhere in the world for an additional $10/day. This was useful for the first day that I landed since we didn’t have any internet connection to get to the bus stop and our Airbnb, but would have cost a fortune to use any longer. 

  • Great for short-term travel (< 3 days)
  • Most convenient
  • Contact with home country
  • Keeps home country phone number
  • Typically very expensive (roughly $10/day)
  • Cookie-cutter plans
  • Data limits
  • Limited texts and minutes

Local Physical SIM card

If you’re traveling for more than a few days, the recommended option is to go with a local SIM card. By purchasing a local SIM card for your destination, you essentially get a local short-term phone plan and a local phone number! 

There are a few considerations to make when going with this option. When you change your number, you no longer can send and receive messages and calls from everyone back home with your home country number, however, you can call and connect with the destination so you can call a restaurant or a taxi company.

Without a SIM card, your phone is essentially a camera that is WiFi-dependent for anything else! Most wireless providers offer various plans for data packages and length of time. This option makes it very affordable to select a plan that is specific to your travels and at a reasonable price. 

A SIM card can be physically inserted into your phone, and many newer smartphones have eSIM compatibility which can be purchased and installed virtually, so you’re ready to travel before leaving home!

Physical SIM

Historically, SIM cards have been physically inserted and removed from the phone, allowing it to change plans. To do this, a user would need to purchase a SIM card beforehand online or find a seller in the destination country to purchase a SIM, and manually switch it out. 

Most providers have plans specific to travelers (3 days up to a few months), so you can get the plan that fits your schedule and data needs. 

One major perk of getting a physical SIM is it can include call & text AND data (unlike an eSIM). While this is a relatively easy option, you may be stuck without data when you land in a foreign place if you didn’t set it up before you left! 

With some older phones, the physical SIM is the only option, which can be purchased online and shipped to you before you leave. Many major airports sell SIM cards (at a slightly higher price), or you can navigate to a local telecom store to start a new plan. 

Be sure to keep your original SIM card in a safe place so you can pop it back in when you return home and have your old number!

  • More affordable than International Plans with a domestic service provider
  • Customizable packages for specific needs
  • Transfers to a local phone number (SIM)
  • A lot of provider and plan options
  • Requires additional planning & activation
  • Transfers to a local phone number (SIM)
  • Risks non-coverage period if not purchased before leaving home country
  • Risks losing domestic SIM (your old number would be gone forever)


Luckily, newer phones have adopted an eSIM capability or electronic SIM. This allows the transition to international phone plans to occur online, and be activated when it is needed! eSIMs essentially work the same as a physical SIM with a few differences. 

An eSIM is purchased through a company that works with a specific provider. For example, you wouldn’t purchase an eSIM through T-Mobile, you would get it through a company like Nomad which uses the best local networks, like T-Mobile. 

*There are some settings to ensure you don’t get astronomical international roaming charges, by keeping all data restricted to the eSIM.

One major difference between a physical SIM and an eSIM is that eSIMs do not have options for call & text, since it doesn’t give you a local number. This is a data-only option! This may prevent you from calling local restaurants, a taxi company, or anything else in your destination country. 

An option to get around this issue is that local places are often on WhatsApp in many countries where tourism is popular. Or, you can get a Google Voice plan that ports your home phone number to Google, where you can make calls and texts from your home number abroad.

eSIMs are made for travelers, so the options are much more flexible and convenient for you! This includes regional plans that extend beyond a specific country’s connection so you can move across borders without worrying about your internet connection. 

eSIMs are virtually embedded into your phone, and use no waste, unlike a physical SIM which is packaged and shipped around the world!

  • Easy to purchase and install anywhere
  • Offers Regional & Global options
  • Keep home country SIM in
  • Easy to manage data usage from an app
  • Doesn’t include call & text (purchased separately)
  • More expensive than a physical SIM
  • Not available for all phones

How To Purchase an eSIM

With eSIMs, it is now easier than ever to update your phone plan to meet your needs almost anywhere in the world. Unless your travel requires a reliable way to call & text locally, an eSIM is the way to go. 

We have been traveling for over a year, and an eSIM paired with Google Voice has been our go-to option for international phone plans. Most places in traveled areas have WhatsApp, so we can stay in contact.

While the following list doesn’t include all the companies that offer eSIMs, they are the most popular with the best service options. This list includes Nomad, Airalo, and Holafly

Once an eSIM plan is purchased online, you will have an activation period where a QR code can be scanned, or a code entered online to activate the purchased data plan. The apps will guide you through the settings on your phone to help you switch your data plan from the physical SIM to the embedded eSIM so you avoid any unwanted roaming charges.

 All 3 of these companies have great apps for Google Play & iOS, where you can purchase and activate your plan, monitor your data usage, and manage your account. 


Nomad is a great option for travelers enjoying long-term stays since almost all of their plans are for 30 days, with the option to add additional data. This option also has regional plan options for APAC, Nordic, Oceania, and Europe, which can all be scaled up or down depending on needs. For example, the Europe plan can include either 25 or 35 countries so you can save money if you don’t need the full coverage.

Nomad eSIM is a great option as a phone plan in Europe.


Airalo has a large variety of service options for over 85 countries globally. Through Airalo, you have the option of selecting a country-specific phone plan or one of their regional or global options depending on your travel schedule, including Europe, Africa, Asia, the Caribbean, LATAM, and MENA. While Airlo has a lot of plan options, it does NOT offer unlimited data plans. 

For additional savings with Airalo, use the code TAYLOR8492 at checkout to save $3!

HolaFly is a great option for any traveler who wants to have Unlimited Data while abroad. This is a great option for Digital Nomads who want to guarantee a stable connection or anyone who wants peace of mind while traveling! 

Unlike Airalo and Nomad, HolaFly doesn’t offer a Global coverage package, but there are country-specific and regional packages, with no difference in price. Since there is no difference in data allotments, the plans only differ in the number of days of coverage. 

Country-Specific eSIM & Regional eSIM Example

  •  5 Days = $19 USD
  • 10 Days = $34 USD
  • 15 Days = $47 USD
  • 20 Days = $54 USD
  • 30 Days = $64 USD
  • 60 Days = $84 USD
  • 90 Days = $99 USD

Summary - International Phone Plans for Every Traveler

Phones have become a necessary tool in this digital age, and they allow us to expand our experiences through research, documenting, and sharing our travels. International phone plans must be reliable and work for your needs.

No more rushing around from WiFi hotspot to hotel for a connection, or facing the slow-speed hotspots that are available. More enjoying the journey worry-free while staying connected.

 Luckily there are a few options to choose from to guarantee you’re connected no matter what. Although you can keep your domestic plan with International Travel add-ons, this option is expensive, which is why I recommend going with an eSIM or a local physical SIM. 

By going with the eSIM option, it will allow you to manage your data without any language barriers or delays, and ensure you’re getting the best deal for what you need! Although this doesn’t allow you to have a local number, by pairing the eSIM with WhatsApp you will have full connection to everyone and most local places too!

What will you do for your international phone plans during your travels?
