eSIM vs roaming: which is better for travel?
Updated · prices in USD from our live catalog
Short answer: For most trips, a prepaid travel eSIM gives you a fixed, known price for mobile data, while roaming is billed by your home carrier under its own roaming terms. Roaming is the easiest option if your carrier includes your destination in your plan; a travel eSIM is usually the better choice when it doesn't, or when you want a hard spending limit.
How they differ
| Travel eSIM (prepaid) | Roaming | |
|---|---|---|
| Who bills you | You pay once, up front, for a set amount of data and days | Your home carrier, according to its roaming tariff or add-on |
| Bill surprises | None: when the data runs out, it stops until you top up or buy another plan | Depends on your carrier's caps and alerts |
| Setup | Scan a QR code before you travel | Nothing to install; turn on roaming |
| Your phone number | Stays on your main SIM (data comes from the eSIM) | Your number works as normal |
| Phone needed | eSIM-capable and carrier-unlocked | Any phone your carrier supports |
When roaming makes sense
If your mobile plan already includes your destination at no extra cost, or you need calls and texts on your own number throughout the trip, roaming can be the simplest option. Check your carrier's current roaming terms before you go.
When a travel eSIM makes sense
If roaming is not included, if you want a fixed price, or if you travel often, a prepaid eSIM lets you choose exactly how much data you need. You can keep your main SIM active for calls and texts and use the eSIM for data.

Questions
Can I use an eSIM and my own SIM at the same time?
Yes, on dual-SIM phones. Keep your main line for calls and texts and set the travel eSIM as your mobile data line.
How do I avoid roaming charges with an eSIM?
Set the travel eSIM as your mobile data line and turn off data roaming for your main SIM. Data roaming must be on for the travel eSIM itself.
Does a travel eSIM include a phone number?
No. These plans are data-only. Your main SIM stays in the phone, so your usual number keeps working for calls and texts where your home carrier allows it, and messaging apps work over the eSIM data.
Is my phone compatible?
You need an eSIM-capable, carrier-unlocked phone. Check the compatible devices list, or dial *#06# and look for an EID number.
When does the plan start?
Validity normally starts when the eSIM first connects to a network at your destination, so you can install it at home before you fly.
