LG Uplus
LG Uplus Data SIM and eSIM products support data and phone or text service on a customer’s phone in Korea.
Síminn
Síminn suits Icelanders who want a home carrier plan rather than a travel-only eSIM, and plans start at ISK 2,600 with a larger data option at ISK 3,100. Coverage spans 64 countries, so a trip outside the region needs a closer look before you book.

- A carrier plan that runs on the Síminn network keeps home use and roaming under one provider
- 5G is listed among the plan features, and Europe roams like home
- Support runs through phone, help centre and email, so a real desk answers questions
Cons
- Roaming sits under a fair use policy, and the unlimited plan counts a separate roaming allowance in the EES

Questions about each
Síminn
How much does Síminn cost?+
Plans start at ISK 2,600, and a larger data option is priced at ISK 3,100. Roaming is billed at a flat daily rate with a daily data allowance per destination, so the total follows the length of your trip rather than a single upfront bundle.
Is the data really unlimited?+
Unlimited data is offered, and unlimited data, 5G and a carrier plan are all listed under unlimited data, 5g and carrier plan. The catch sits in the fair use policy: roaming is capped in steps, and the unlimited plan counts a separate roaming allowance in the EES, so roaming past that is charged.
How many countries does Síminn cover?+
Coverage runs to 64 countries, and the listed region is regional rather than global. Destinations differ in what you get per day, with the United States and Switzerland on a higher daily allowance than the UK, Japan, Thailand, Turkey and Mexico.
Is this a travel eSIM or a home plan?+
This is a carrier plan rather than a single-destination travel eSIM. The seller type listed for Síminn is a carrier, so the same plan covers daily use in Iceland and trips abroad, and top-ups are available for adding data later without a new plan.
