How do I add a travel plan with my mobile service provider?

Signing up for a travel plan with your mobile service provider is usually pretty easy.

Is an eSIM cheaper than roaming?

In most cases, yes. In our comparison, a Saily eSIM for 7 days in Mexico cost around $7, while the cheapest carrier travel plan ran $60. For a month in Europe, the gap was roughly $17 versus $60. The savings grow on longer trips, though a travel plan can still be worth the higher cost if you need to keep your home number.

Can I keep my phone number with an eSIM?

Usually not. Most travel eSIMs, including Saily, are data-only, so you cannot make or receive calls and texts on your usual number. A few providers offer a local number in select countries, but it is not your home number. If keeping your number matters, a carrier travel plan or roaming is the better fit.

Do all phones support eSIMs?

No. Your device needs to be eSIM-compatible and unlocked. Most recent iPhones, Google Pixels, and Samsung Galaxy models support eSIMs, but many older or budget phones do not. Before you buy a plan, check your phone's settings or the manufacturer's website to confirm that it supports eSIMs.

What happens if I turn on my phone abroad without a plan?

If you switch on your phone abroad without an eSIM or a travel plan in place, your device can connect to a local network and trigger pay-per-use roaming charges. These rates are much higher than any travel plan, so they can lead to a large bill. To avoid this, set up an eSIM or add a travel plan before you leave, or turn off data roaming until you do.
