Key Takeaways: eSIM vs International Plans

  • eSIM providers let you buy in advance a certain amount of mobile data for travel to various countries and regions. 
  • Your home mobile carrier can set up an international plan, which lets you use your usual phone plan abroad. 
  • As a seasoned traveler, I recommend eSIM plans over international plans, as they’re cheaper and give you more control over how much you’re spending on data.

  • Budgeting: If you’re like me and live for budgeting, eSIM plans are the best choice when traveling abroad. You simply choose how much data you’ll need and pay in advance. You won’t face any extra charges if you run out of data — you’ll just have to buy another plan.
  • Calling and texting: International plans let you continue using your home phone number abroad. As a cheaper alternative, you can use your eSIM data with services like WhatsApp for calling and messaging. That said, some eSIM services, like Airalo, have plans with calling and texting capability.
  • Flexibility: Knowing exactly what to expect (there’s less fine print to trawl through) and being able to choose from a wide variety of affordable plans are reasons enough for me to opt for an eSIM package.

International roaming fees are a major pain point for any traveler, and anyone who uses a roaming plan is sure to be familiar with the constant worry about “surprise” fees. Travel eSIM plans are a decent solution, but they’ve only just started to gain popularity with everyday travelers. My eSIM vs international plan guide is for those who want to get up to speed.

In this guide, I’ll cover the key differences between international roaming plans and eSIM plans, and share my top tips on choosing the best option for you. To learn more about the top eSIM picks, head over to the Cloudwards best international eSIMs guide.

What Is an eSIM?

An eSIM is a digital SIM card that’s embedded in your phone, allowing you to buy different cellular plans. When you buy an eSIM mobile data plan, you do it via an app or a website and install it directly on your phone using the internet instead of physically inserting a SIM card.

More to the point, travel eSIM providers specialize in mobile data plans (sometimes with call and text functionality) for various countries and regions. You can also usually opt for a global plan. If you’re a beginner, check out our guide on eSIMs.

What Is an International Roaming Plan?

An international roaming plan, which you set up via your local mobile carrier (such as T-Mobile, Verizon, etc.), simply lets you make phone calls, send text messages and use mobile data when you travel to other countries. The local mobile carrier partners with networks in other countries.

International roaming plans come in various forms,
including monthly subscription packages. 

Many international plans are subscription-based and provide a certain amount of data (plus texts and/or phone calls in some cases) for the chosen period.

How to Choose Between an eSIM vs International Plan

The key factors I’d consider if I had to choose between an eSIM and an international plan include cost, coverage, mobile hotspot availability, security and privacy.

Cost & Pricing

In general, eSIM plans are cheaper than international plans, with the average price for 1GB and seven days of validity going for around $4. What’s more, the cost per gigabyte typically decreases if you buy a bigger plan. Let’s use well-known eSIM service Saily as an example: The 20-GB U.S. plan (30 days of validity) breaks down to about $1.80 per gigabyte.

As I touched on above, eSIM plans are prepaid in most cases. This means you don’t have to worry about overspending. Some eSIM providers offer free trials, and some have rewards systems in place that you can use to make future eSIM purchases cheaper.

Coverage & Network Stability

It’s common for both eSIM plans and international roaming plans to partner with networks in a large number of destinations — more than 200 in some cases.

However, the connection you get (4G, 5G, etc.) depends on what the local partner carrier supports. Your location and how congested the network is can also impact speeds. Therefore, no matter which plan you go for, fast speeds are not always a given.

Mobile Hotspot Availability

Both eSIM plans and international plans typically let you use your hotspot abroad, which can eat up your data more quickly depending on which devices are connected to the hotspot and what they’re being used for. With international plans, it’s wise to check any extra charges you may incur if you end up going over your data allowance.

Security & Privacy

eSIMs are more secure than international plans linked to a physical SIM card because they can’t be removed, thereby reducing the risk of SIM swapping and cloning. However, eSIMs are not foolproof and can still be hacked — it’s just less likely. Furthermore, mobile carriers can track your location regardless of SIM type. 

What About Purchasing a Local Physical SIM Card?

Local SIM cards are often readily available in airports and places like convenience stores. There’s no setup — you just pop one in your SIM tray and away you go — and local rates in some countries can be really low.

On the flip side, they’re ideal only for one-off trips or trips to one country. If you’re a frequent jetsetter, keeping track of a bunch of tiny chips could soon turn into a major headache. Additionally, bear in mind that local SIM regulations can vary greatly from country to country, so you may experience lengthy registration procedures in some destinations. 

The Best eSIM for Travel

If eSIMs have won you over, I recommend checking out these three based on my testing. 

1. Saily — Saily is a NordVPN product, and it has an edge over competitors with its extra security features. What’s more, in my experience, the quality of its customer support is on another level. Learn more in this Saily review

2. Airalo — Airalo is an established provider with reasonable pricing and a free trial in eight countries. It also offers some call and text plans in addition to data-only plans. This Airalo review will give you the full lowdown. 

3. Holafly — Holafly stood out to me during testing with its meticulous (and super nice) support team, as we explain in this Holafly review. If you’re interested in unlimited plans, I recommend checking out this provider. 

Final Thoughts: Our Honest Recommendation

I prefer eSIM plans for traveling abroad because they’re more affordable and flexible, and I like the comfort of always knowing exactly what I’m getting. With eSIM packages, if you run out of data, that’s it; you won’t be slapped with surprise extra fees, which is always a risk with international roaming.
