Our verdict

Rocket eSIM suits travellers who want broad coverage and a choice of a capped package or the Europe no traffic policy plan, with the smallest packages listed at $8. It works as a marketplace seller, so the value sits in picking the right package rather than in the brand name.

Pros and cons

Pros

  • Coverage of from 150 countries sits well above the site median of 74.
  • Plans are shaped around short trip and long trip, so a short break and a long stay both find a matching package.
  • unlimited data, hotspot and instant activation puts unlimited data, hotspot sharing and instant activation on the same plan set.
  • Top-ups are available, so extra data can be added mid-trip without a new purchase.

Cons

  • A per GB figure of $2.67 sits above the site median of €1.50, so heavy data use is dearer here.
  • Rocket eSIM operates as a marketplace seller (marketplace), so a reseller stands between the buyer and the network.
  • Regional pricing is uneven: $25 in Europe against $23 in Japan for a comparable package.

Who it suits

  • Travellers to Europe or Japan who want a small package rather than a large allowance
  • People who want capped and unlimited options inside one global catalogue
  • Shoppers who like to weigh several operators before picking a network

Who should look elsewhere

  • Zwitchy, for a wider catalogue: it covers 200 countries.
  • eSIMGo.is, when the entry price decides it: plans start at $0.99.
  • SimToIsrael, for a single market: its plans start at $25.

The company behind it

The company behind the plans is Rocket Telekom, the name that appears in the terms of sale, which is the detail to keep on a receipt or a refund request. Support runs by email, chat and phone, so a question about a data package, a top-up or an activation can go to email, chat or phone. Several channels in one place keep a stalled plan from turning into a whole trip without data.

Frequently asked questions

What does a Rocket eSIM plan cost?+

The smallest packages are listed at $8. A mid-sized Europe package is $25 and the comparable Japan package is $23, so the region moves the price of the same allowance. A no traffic policy plan sits at the top of the Europe range.

What does the data cost per GB?+

The lowest per GB figure is $2.67 against a site median of €1.50 and a lower quartile of €0.81. That places the cheapest Rocket eSIM data above the middle of the field, so heavy data use costs more per gigabyte than at the budget end.

How many countries does Rocket eSIM cover?+

Coverage spans from 150 countries on a global basis, ahead of the site median of 74 and inside the 160 upper quartile. Named prices sit in Europe and Japan, so those are the markets where a specific package can be weighed before buying.

Does Rocket eSIM sell unlimited data?+

Unlimited data is available, and it is one of the entries in unlimited data, hotspot and instant activation. The Europe range steps up from small capped packages to a no traffic policy plan, while the Japan range is sold in fixed allowances, so the uncapped route is a regional choice rather than one option across the whole catalogue.

Which networks does Rocket eSIM use?+

The networks named for the plan set are Eurolink, 3 AT and Asialink, a mix of several operators rather than a single host network. The local carrier can therefore differ by country, so the network shown on the chosen plan is the one to check against the places being visited.

Can I top up while I am travelling?+

Top-ups are available, so data can be added to an existing plan without buying a new one. The plan set is built for short trip and long trip, which means a short city break and a longer stay sit in the same catalogue, and a top-up covers a trip that ran heavier than planned.

Can I share the connection as a hotspot?+

Hotspot sharing is listed in unlimited data, hotspot and instant activation next to instant activation, so a phone or laptop can share the connection and the eSIM activates without a store visit or a plastic SIM. Tethering is part of the described package rather than an add-on.
