Our verdict: Backup only — too expensive for primary use

At ~$10.80 per GB, Drimsim is the most expensive provider we list. Its value lies not in price-per-GB but in flexibility: one eSIM, 197 countries, no expiring data. Think of it as travel data insurance — top up €25, keep it as a backup, and use it only when your primary eSIM fails or you're in a country without a plan. For everyday travel data, Airalo or Saily are 5–10× cheaper.

Overview

Drimsim takes a fundamentally different approach from every other provider on this site. Instead of selling data plans with set amounts and expiration dates, Drimsim sells you one eSIM (€10) and then charges per megabyte as you use data. You top up a balance (€25 minimum), and it gets depleted based on usage at country-specific rates.

The eSIM never expires as long as you have some activity within 360 days. Your unused balance carries over indefinitely. This makes it unique as a permanent travel companion — activate it once, and it's ready whenever you need it, in any of 197 supported countries.

Pricing — The Real Numbers

Drimsim charges €0.01 per MB in most popular travel destinations. This sounds cheap per megabyte, but scales up quickly:

Reality check: €0.01/MB × 1,024 MB = €10.24/GB ≈ $10.80 per GB. Compare this to Airalo at $1.30/GB or Saily at $1.20/GB for the same destinations. You're paying roughly 8× more per GB with Drimsim.

The €0.01/MB rate applies to Japan, all of Europe, Thailand, Turkey, South Korea, Indonesia, USA, Egypt, Georgia, Greece, and most other popular destinations. Some regions may be more expensive — always check rates in the Drimsim app before traveling.

Additional costs: the eSIM itself is €10 (one-time), minimum top-up is €25, and after 360 days of inactivity, a €0.50/month fee kicks in.

When Drimsim Makes Sense

As a backup eSIM. Top up €25, install it, and forget about it. If your primary eSIM fails, you have instant connectivity in 197 countries. At $10.80/GB, checking a map or sending a few messages costs pennies.

For extremely light use. If you only need data for occasional map checks and rely on Wi-Fi for everything else, spending $1-2 on Drimsim per trip may beat buying a full prepaid plan you won't use.

Multi-country hopping with minimal data. Visiting 5 countries in 2 weeks and just need emergency data? One Drimsim beats buying 5 separate prepaid plans.

Coverage & Performance

Drimsim partners with 400+ carriers across 197 countries, including major names like Vodafone, AT&T, and China Mobile. When you arrive in a country, the eSIM automatically connects to a local network.

Speed tests from independent reviews show typical 4G speeds of 15–30 Mbps — on the lower end compared to providers like Airalo or Saily, but functional for most basic needs. One reviewer noted Drimsim had the slowest speeds among 10+ eSIMs tested.

Frequently asked questions about Drimsim

Most popular destinations cost €0.01 per MB, which works out to roughly €10 per GB or about $10.80 USD per GB. This is significantly more expensive than prepaid eSIM plans from other providers.
Only in specific scenarios: as a backup SIM for emergencies, for very light usage across many countries, or if you value the simplicity of one SIM that never expires. For regular data usage, prepaid plans from Airalo or Saily are 5-10× cheaper per GB.
No. Your balance stays as long as you have any activity (call, text, or data session) within 360 days. After 360 days of inactivity, a €0.50/month fee starts.
Yes. Drimsim allows data sharing and hotspot without restrictions.
Airalo offers much better value per GB — typically $1-2/GB vs Drimsim's ~$10.80/GB. However, Drimsim's balance never expires and works in 197 countries without buying separate plans. Airalo is better for regular use; Drimsim works as a backup.
