Horizon eSIM review

Read this before you buy from Horizon eSIM

Horizon is the cheapest seller on this site in a good number of destinations, and it has the most generous refund policy we have read anywhere: a full refund on request with no time limit, even after the data is used. The prices you see on our pages already include the ten percent our readers get, so there is no code to type. What it does not tell you is which country the company behind it is registered in, which matters because its own terms hang the governing law on exactly that.

• The price in our table is what you pay, and it already has the reader discount in it. Their own feed quotes undiscounted retail, but arriving through a link from this site sets a cookie and their checkout takes ten percent off on its own. We checked it on their Africa range: 4.09, 6.69, 13.09 and 25.99 euro became 3.69, 6.03, 11.79 and 23.40, and going back without the cookie put the old prices straight back. So there is no coupon to enter and no code next to their rows, because the discount is already in the number. We take it off the euro price the same way their checkout does, rounded to the whole cent, so the euro amount behind each of our dollar figures matches theirs exactly.
• Their refund policy is the most generous we have read, and it is worth reading yourself. Their published policy says they always refund the full amount you paid when you ask, whether the eSIM is unused, partly used or fully used, with no time limit, no fee deducted and no reason required. Top ups are covered too. Every other seller on this site voids your refund the moment you activate. We are reporting their published policy, not a promise we can enforce, so keep your order number.
• Nobody tells you what country you are buying from. Their terms say Horizon is a brand of LuShen L.L.C., trade name LSHTech, business registration number 812292598, and then say the governing law is the law of the country where that company is registered and that disputes go to the courts of its registered seat. That country is named nowhere on the site, and there is no postal address either. So you cannot tell which law covers your purchase, which court would hear a claim, or which register to look the company up in. We have asked them.
• You pay in euros, not dollars. They sell in euros only, so the dollar figures in our tables are converted at the European Central Bank daily reference rate and refreshed every night. Your card is charged the euro amount and your bank adds its own rate on top.
• We show hotspot and top ups only because they confirmed them in writing. Their feed marks every plan as allowing both, and a blanket yes like that has been wrong before on another seller, so we asked. They told us hotspot is included on every plan on compatible phones, and that you can top up any plan except Kosovo, as long as your Horizon eSIM is still eligible. Their app checks that, and an eSIM that has been suspended or deleted may not take a top up. Kosovo plans cannot be topped up at all, so you buy a new eSIM. Their feed still says Kosovo can be topped up. It cannot, so we show no top ups on Kosovo plans.
• They are fairly new. The domain was registered in February 2024, so it was about nineteen months old when we listed them. Payments are handled by Paysera rather than in house.
• We could not read any independent review score. Trustpilot blocks our server, so unlike some sellers we cannot tell you whether a profile exists or what it says.
• On price they are genuinely strong. At the discounted price a reader actually pays, their median plan works out around a dollar and a quarter per gigabyte against a market median near three dollars, and they come out cheapest on a large share of the destinations we compare. That is the ranking maths alone, and no seller can pay to change it.

We list Horizon eSIM because its prices are real and its plans rank on the same maths as everyone else's. We publish what we could not verify so you can decide with the facts in front of you.
