1. Why I Don't Recommend Carrier Roaming

Unless you're traveling strictly for business and need your native phone number,

most vacationers and students rarely make traditional voice calls abroad.

With a solid data connection from an eSIM, you can easily use WhatsApp, FaceTime, or Messenger

to make all the calls you need.

There's simply no reason to pay exorbitant daily roaming fees!

Furthermore, I've noticed that carrier roaming can sometimes drop out or become frustratingly slow

when crossing borders between European countries.

Because of these connectivity hiccups,

I now exclusively rely on eSIMs for all my international travels.

On the left is the pricing for a 10-day USIMSA plan,

and on the right is the pricing for Holafly.

While USIMSA can sometimes be competitive for very short trips,

Holafly proved to be significantly cheaper for this 10-day comparison.

The beauty of Holafly is that the longer your trip,

the cheaper the daily rate becomes.

If you're backpacking or vacationing across Europe, it's unbeatable!

3. My Personal Experience

My Eurotrip kicked off in France.

The moment my plane touched down, I switched on my data

and immediately pulled up Google Maps to navigate to my hotel.

I spent my days exploring world-famous landmarks,

and indulging in incredible local cuisine, all while staying perfectly connected.

The absolute best part? As I crossed borders into different European countries,

I didn't have to waste time buying new local SIM cards.

My data connection never dropped or throttled down,

making my entire journey completely stress-free.

Whenever friends ask me which provider to use,

I always tell them that for trips lasting more than a week,

choosing Holafly over USIMSA is

the smartest way to save money!

is a massive game-changer.
