Our verdict on each
Claro Guatemala
Claro Guatemala is a carrier eSIM add-on that suits short trips and long trips around the Americas, with coverage across 30 countries and a plan price starting at GTQ 40. Read the unlimited data claim with the fair use policy beside it, because roaming draws on your plan data.
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.

Questions about each
Claro Guatemala
How much does Claro Guatemala roaming cost?+
Conexion Sin Fronteras sits at a plan price starting from GTQ 40, and roaming in the US, Canada, Mexico and Central and South America adds no extra cost on postpago plans. Europe including the UK is charged by the day, and Japan, Turkey and the rest of the world carry higher daily rates.
Is the data allowance really unlimited?+
Unlimited data is listed for postpago roaming plans, but fair use applies: roaming is capped at a daily allowance drawn from your plan data, and Claro Guatemala publishes a Politica de Uso Justo. Heavy streaming abroad is the case worth checking before you commit.
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.
