Drimsim eSIM review: prices, coverage and our verdict

Prices and value

Drimsim works differently from most eSIM sellers. Instead of fixed data bundles, you buy the SIM card or eSIM for €10, add money to a balance and pay only for the data you use. Its country pages list the rate per MB, and its site says traffic is measured in kilobytes. In most of the countries it covers, the rate is €0.01 per MB, the same for the physical SIM and the eSIM.

Because the rate is charged per MB, the cost of a gigabyte is simply the per-MB rate multiplied by 1,024, not a special plan. The price block beside this section shows its current prices per country, and some countries cost far more than €0.01 per MB.

The pay-per-use model has one real upside: nothing is wasted. If you only check maps and send messages, a few euros of balance can last a trip, and what is left stays on the account for next time. For heavier use, such as video calls, streaming or working from your laptop, the per-MB charges add up quickly and a fixed data bundle may suit you better.

Coverage and networks

Its own site advertises 190+ countries, and the country list beside this section shows where it is currently offered. Its rates page covers Europe, much of Asia, the Americas, parts of Africa and Oceania. The SIM is not tied to one carrier: Drimsim says it connects to a local network in each country and switches rates as you cross a border.

There are no separate regional or global plans because one balance already works everywhere it covers. The catch is that prices vary by country. Most popular destinations, including Spain, France, the UK, the US, Japan and Thailand, are €0.01 per MB, but places such as Fiji, Papua New Guinea, Cameroon and Ivory Coast are €0.20 per MB, Seychelles is €0.30 and Burkina Faso €0.50. Check the country page before you travel.

Plans and flexibility

There are no plans to pick, no validity period to watch and no unlimited option. You top up the balance in the app and data is charged as you use it. Its terms say you can turn on automatic top-ups from your card when the balance runs low, and that a negative balance can be charged to your saved payment method, so it is worth checking that setting.

Drimsim says the SIM does not expire, which makes it handy if you travel a few times a year. Its terms do add a condition: if the SIM has no activity for 360 days, €3 a month is taken from the balance until you use it again, and the SIM is cancelled if the balance runs out.

The Drimsim app page also describes calls over the internet from the app, with Drimsim-to-Drimsim calls free and the price per minute shown before you call. The eSIM itself is sold for data.

Buying, setup and the app

You can order the eSIM on the website or in the app. Drimsim says it is delivered by email within about two minutes as a QR code, and its activation page asks you to install the Drimsim app to activate it. It lists compatible phones, including iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer and some Xiaomi models. A physical SIM in nano, micro or mini size is also available, sent by registered mail with shipping charged by region.

Payments go through Stripe and Drimsim says it accepts the most common bank cards. The app is used to top up, follow spending, contact support and refer friends: its referral scheme gives €7 to both of you once a friend orders the SIM and tops up €25.

Support and refunds

Drimsim says its support works 24/7 in live chat, in English and Russian, with human operators. You can also reach it by email or through its Facebook page, and the app includes a guide for when you lose connection completely.

Its refund page offers a refund of the SIM price plus the balance if a connection problem is not fixed within 24 hours of contacting support, and a refund of the SIM price if you never opened the SIM or installed the eSIM. Shipping costs and referral bonuses are not refunded. Its terms are stricter on balance: you can only claim back payments made in the previous 14 days. Refunds go back to the original payment method.

Is Drimsim legit?

Yes, Drimsim is an established service. Its website names Drimsim Limited, with an address in Hong Kong, and the iOS app is published by Drimnano SL. Press coverage dates the product to the mid-2010s, which makes it one of the older travel SIM brands.

Public ratings are limited and mixed. It scores 3.2 on Trustpilot from 12 reviews, and the app has 3.5 on the App Store from 15 ratings (October 2026). Trustpilot reviewers who are happy mention long-lasting credit and frequent travel, while negative reviews mention the cost, balance running down quickly and setup problems. Its terms also say Drimsim may ask for proof of identity when you activate the SIM.
