Which is best: local SIM, eSIM, or roaming?

Short answer:

• eSIM → best for most travelers (cost + convenience)
• Local SIM → best for long stays in one country
• Roaming → best for very short trips or zero setup

If you’re taking a typical trip, a travel eSIM like Nomad eSIM is usually the simplest and most practical choice.

What is a travel eSIM?

A travel eSIM is a digital SIM you install on your phone without inserting a physical card.

Instead of buying a SIM at your destination, you:

• purchase a plan online
• install it before your trip
• connect as soon as you land

Providers like Nomad eSIM offer plans across multiple countries, so you can stay connected without switching SIMs.

Is eSIM cheaper than roaming?

In most cases, yes. eSIM plans typically:

• cost less than international roaming
• provide better value per GB
• avoid unexpected charges

Roaming may be convenient, but eSIM is usually more cost-efficient for travel.

Can I use eSIM and my SIM card at the same time?

Yes, most smartphones support dual SIM. This allows you to use your eSIM for data, while keeping your main number active (for OTPs, messages) and avoiding roaming charges.

So, should I get a local SIM, a travel eSIM, or just roam?

It depends on your priorities, but here’s a simple way to decide:

Get a travel eSIM if…

• You value convenience of being able to quickly switch lines while also keeping your primary line active
• You don't need a local phone number
• You are cost-sensitive
• You are traveling to multiple countries
• Your device doesn't have support for physical SIMs and local carriers at your destination doesn't have eSIM support for travelers

Get a local SIM if…

• You need a local phone number (but, do you really need a local phone number?)
• You are very cost-sensitive
• You don't mind the hassle of having to change out SIM cards or to queue at the shops at the counter
• You don't need to have your primary line active during your trip
• You device is not eSIM-compatible -- check if your device is eSIM-compatible

Just roam if…

• Cost is not really a concern to you
• You want zero set up.
• Your device doesn't support multiple SIMs.
