What's Actually Cheapest for Data Abroad? The Guide by Traveler Type

"What's actually cheapest for data abroad" doesn't have one answer: it depends on how long you're traveling, how many people are traveling with you, and where you're headed. For a short solo trip, an eSIM will almost always win on price and simplicity. For a stay of a month or more, a local physical SIM can end up cheaper over the long run. For a group with several laptops and devices, a shared Pocket Wi-Fi can be more cost-effective than several separate data packages. And one thing holds true almost every time: an Israeli carrier's roaming package is almost never the cheapest option.

Unlike guides that insist one option is "always cheapest," the honest answer depends on your trip's profile. Rather than push one solution on everyone, we've broken it down by traveler type, so you can see exactly which category you fall into and why. An eSIM, for context, is simply a digital SIM built into your phone, as defined by the GSMA eSIM standard: no physical card required.

Key Takeaways

• Short solo trip (up to two weeks) → an eSIM is almost always the most cost-effective option.
• Long stay of a month or more → a local physical SIM can win on total cost.
• Group trip with lots of devices and laptops → a shared Pocket Wi-Fi is worth considering.
• Your Israeli carrier's roaming package is almost never the cheapest option; see our full comparison.

In short: what fits whom

• Solo traveler, up to two weeks: A 5–10GB eSIM, installed from home, no time lost at a kiosk at your destination.
• Stay of a month or more: An eSIM for the first few days, then it's worth checking a local SIM's monthly plan, which is usually cheaper per GB over the long run.
• Group of 4+ traveling together: Compare shared Pocket Wi-Fi pricing against a personal eSIM for each traveler. For smaller groups, a personal eSIM is almost always cheaper and simpler.
• Business trip, heavy data use: A 20GB+ eSIM package (about ₪39.90–₪70.90 with SimSIM) versus ₪199–₪299 for a carrier's business roaming package.

The prices mentioned here are based on our most recent price checks against carrier websites and SimSIM's pricing, as detailed by the date shown in each linked article.

Short solo trips: where eSIM almost always wins

If you're traveling alone for a week or two, an eSIM is almost always the cheapest and simplest option, for two reasons: the price for a small-to-medium amount of data (5–10GB), and the time you don't waste. An eSIM package installs at home before your flight, with no line at a kiosk and no hunting for a SIM shop at your destination.

Even if a local physical SIM's price for a similar amount of data is slightly cheaper, you're still "paying" in time: finding a kiosk, waiting in line, and sometimes needing documents or a local ID to make the purchase. For a short trip, that time cost is almost never worth the small price difference.

We've broken down the full comparison, install time, real prices, and device compatibility, in eSIM vs Physical SIM: Which Is Better for Travel in 2026? If your device supports eSIM and isn't carrier-locked, it will almost always be the right choice for a short solo trip.

Long stays of a month or more: this is where a physical SIM is worth checking too

With most eSIM providers, including SimSIM, packages are sold in units of up to 30 days. A stay of two to three months means buying several packages back to back, and that can start to add up. A local physical SIM, on the other hand, is often sold in renewing monthly plans with a more generous amount of data per unit of cost, because the local carrier is competing for long-term resident customers, not just tourists.

A physical SIM for a long stay also gives you a real local phone number, useful if you need to sign up for local services, open a temporary bank account, or want local contacts to have a number to reach you at.

The downside: you still need to find a kiosk or shop at your destination. You can't install a physical SIM in advance from home the way you can with an eSIM, and your Israeli SIM won't stay active in the same device unless you have a second phone, as we detailed in eSIM vs Physical SIM: Which Is Better for Travel in 2026? So for a long stay, it's worth considering a combination: an eSIM for the first few days, installed from home and working the moment you land, then switching to a local physical SIM once you've settled in, if the local pricing does turn out cheaper per GB over the long run.

Group trips: when Pocket Wi-Fi is worth it, and when it isn't

Pocket Wi-Fi (a portable cellular router) is a separate device that connects to the local cellular network and broadcasts Wi-Fi to several devices at once. For a solo traveler or a couple, it's almost always an unnecessary extra expense and hassle: you have to carry an extra device, charge it, and return it at the end of the trip. But for a large group (four or more people) traveling together for most of the trip, for example an extended family sharing a car, or a work team with several laptops, the cost of a shared device splits between everyone, and it can sometimes come out cheaper than buying a separate eSIM package for each person.

Worth stating clearly: SimSIM doesn't sell Pocket Wi-Fi rentals itself. This is simply an option worth knowing about when planning a group trip. The practical consideration: if everyone in the group also needs to keep their Israeli number active for personal calls and WhatsApp, a personal eSIM for each traveler still gives them that easily. With a shared Pocket Wi-Fi, every device connects to the same Wi-Fi network, but each person's individual phone number doesn't get data through it, only a shared internet connection. For groups smaller than four people, a personal eSIM for each traveler is still simpler and cheaper in most cases.

Business trips with high data use

For a business trip with video calls, uploading large files, or ongoing work from your phone and laptop, a large data package (20GB or more) will almost always come out cheaper than an Israeli carrier's business roaming package. According to the comparison we ran in SimSIM eSIM vs. Israeli Carrier Roaming: What It Actually Costs, roaming packages from Pelephone, Partner, and Cellcom range from ₪199 to ₪299, while a large SimSIM eSIM package (20GB, 30-day validity) costs ₪39.90–₪70.90 depending on destination.

One important point for business travelers: SimSIM's eSIM package is data-only; it doesn't include calls or SMS on a foreign number. If you rely on WhatsApp, Teams, or Zoom calls over data, this makes no difference. If you specifically need to make or receive calls on a real local phone number for work purposes, that's a separate consideration worth checking against your exact needs before you travel, for example with Pelephone, Partner, or Cellcom, if their business package is actually relevant to you.

It's also worth making sure, before a business trip, that your installation is set up before you fly, not in the middle of your first meeting at your destination. Install the profile at home over trusted Wi-Fi, and activate the package only once you land.

Our takeaway

There's no single answer that's right for everyone, but there is a simple way to choose: start by checking how long you're traveling and with how many people. Short solo trip: eSIM. Long stay: it's worth checking a local SIM too. Large group with lots of devices: Pocket Wi-Fi is worth checking. And in every case, it's worth checking first whether your carrier's roaming package is really the best deal; usually it isn't, as we detailed in SimSIM eSIM vs. Israeli Carrier Roaming: What It Actually Costs.

You can browse all of SimSIM's destinations and check current prices for your specific destination, or first confirm your device supports eSIM in the list of compatible devices.
