Getting online abroad used to mean either a shocking roaming bill or hunting for a SIM card in an airport kiosk. eSIMs changed that — but the best choice still depends on your phone, your trip and how much you value convenience. Here's how the three options really compare, so you land with data and no nasty surprise on your bill. Figures below are accurate as of June 2026. Card issuers change welcome offers, fees and perks frequently — always confirm the current terms on the issuer's page before you apply, or ask Mike in the app for what's live right now.
The three ways to get data abroad
You have three real options: keep your home plan and pay to roam; buy a travel eSIM you install before you fly; or pick up a local physical SIM at your destination. Roaming is the most convenient and often the most expensive; a local SIM is usually cheapest but the most hassle; a travel eSIM sits in the sweet spot — cheap-ish, and ready before you even land.
- Roaming: most convenient, often priciest
- Local SIM: usually cheapest, most hassle
- Travel eSIM: the convenient middle ground, ready on arrival
Why eSIMs won over most travelers
A travel eSIM is a data plan you buy online and install on a compatible phone before you leave — no physical card, no kiosk, no swapping out your home SIM. You land, switch it on, and you're connected, while keeping your normal number reachable on your primary line. For most modern-phone travelers, it's now the default answer.
- Buy and install online before you fly — connected on landing
- No physical SIM to swap or lose; keep your home number active
- The default choice for most modern, compatible phones
When roaming still makes sense
Don't dismiss your home plan. Some carriers include free or cheap roaming, or sell a flat daily travel pass that's genuinely good value for short trips — and it's the most effortless option, with your normal number and no setup. For a quick trip, or if your plan already includes the destination, roaming can be the easiest and even the cheapest choice. Check before you assume it's a rip-off.
- Some plans include roaming or a fair flat daily pass
- Zero setup, your normal number, fully effortless
- Great for short trips — check your plan before writing it off
When a local SIM still wins
For long stays, heavy data use, or destinations where you want a local number, a local physical SIM is often the cheapest by a wide margin. The trade-off is effort: buying it (sometimes with ID), installing it, and losing easy use of your home number. If you're staying weeks and using lots of data, that hassle can be well worth the savings.
- Cheapest for long stays and heavy data
- Gives you a local number where that's useful
- Trade-off: setup effort and juggling your home number
How to choose in one line
Short trip and your plan has a fair travel pass → just roam. Modern phone and you want cheap, ready-on-arrival data → a travel eSIM. Long stay, heavy use, or you need a local number → a local SIM. Whatever you pick, sort it before you fly, and turn off background app updates and data-hungry settings to make your allowance last.
- Short trip + fair plan → roam; modern phone → eSIM; long/heavy → local SIM
- Sort connectivity before you fly, not at the gate
- Throttle background data so your allowance lasts
| Option | Cost | Convenience | Best for |
|---|---|---|---|
| Roaming (home plan) | High, or a flat daily pass | Highest — zero setup | Short trips, plans with a travel pass |
| Travel eSIM | Low–medium | High — ready on arrival | Most modern-phone travelers |
| Local SIM | Lowest | Lowest — buy & install there | Long stays, heavy data, local number |
Key takeaways
- Three options: roam on your home plan, a travel eSIM installed before you fly, or a local SIM at your destination.
- A travel eSIM is the sweet spot for most modern phones — cheap-ish and connected the moment you land.
- Roaming can still win for short trips if your plan includes a fair travel pass.
- A local SIM is cheapest for long stays and heavy data, at the cost of setup effort.
You never need to land abroad disconnected or dread the bill again. Match the method to your trip — roam for short hops with a fair pass, an eSIM for easy ready-on-arrival data, a local SIM for long heavy stays — sort it before you fly, and you'll step off the plane already online.
