Quick verdict on MyBestSim
MyBestSim calls itself an eSIM comparator. MyBestSim leans on a selection, guides and codes. On 28 August 2026 the gap is awkward: lots of promo talk, but several of those operators do not appear on destination listing pages. It is not a shop. Like most directories, it hands you to the operator checkout. Affiliation is the business. That is fine until volume, or a promo banner, stands in for an explanation.
A search for “MyBestSim review” is not a scam check. The site is a discovery tool. The useful question, on 28 August 2026, is whether the list shortens the choice or stretches it.
- Useful if you want a written guide first, then you check the code’s operator is actually on the country listing.
- On 28 August 2026, MyBestSim shows codes while operators are missing from country listings. A code with no listed plan tells you neither the price, nor the network, nor if the pack still exists.
- To compare two offers properly, go to eSIM Comparaison: same fields (price, GB, validity, 5G, hotspot), then pay at the operator.
What it is and how it works
The usual path: type a destination, MyBestSim returns plans. MyBestSim leans on a selection, guides and codes. On 28 August 2026 the gap is awkward: lots of promo talk, but several of those operators do not appear on destination listing pages. The destination pages on eSIM Comparaison answer the same question from a catalog that has already dropped duplicate rows.
MyBestSim does not sell the eSIM. The product is the list, sometimes a code, sometimes a review. The creator is visible. That helps. Curation still means what is not listed does not exist for the reader. A code with no country plan card is not a comparison.
“5 GB / 7 days” is not one object. It can be a named local operator, an MVNO, or a regional pack with a fair-use cap. MyBestSim shows the offers. It does not always translate between them.
Filters and results
You mainly compare brands on the country page. Less noise. The catch on 28 August 2026: an operator can have a shop-window code and still be missing from the listing. Then the code does not help you pick a pack.
Sort by price and the top of the list is a thin, short pack. Sort by data and a one-week trip disappears under long or unlimited rows with a fair-use clause.
A brand-wide review says nothing about a week in Osaka. Open the country page and, when you can, the local network name.
A promo code counts only if it still works at checkout today, and only if that operator is actually listed for the destination. On eSIM Comparaison, the promo codes in the catalog are rechecked every day.
- Filter first by the real length of the trip, not by the cheapest pack.
- Check hotspot and 5G before you judge the price per GB.
- For Europe, open the country list on the pack, not only the word Europe.
- A review with no country and no date weighs little against a network card.
Strengths
- Readable editorial, with a face behind the site.
- Operator guides more human than a raw table.
- Less noise than a giant directory, when the brand is actually listed.
- Useful for a first frame among big names, not to close the purchase.
- The teaching tone helps if you have never installed an eSIM.
Real weaknesses
- Codes versus listings gap: operators pushed via promos do not appear on country pages, on 28 August 2026.
- A code with no comparable plan on the destination cannot tell you the price.
- The selection is short: what is not listed does not exist for the reader.
- Curation can track partnerships, even in good faith.
- Fewer normalised fields (5G, hotspot, named network) on one grid.
Who MyBestSim is for
Useful if you want a written guide first, then you check the code’s operator is actually on the country listing.
Not reliable as a single source. A promo banner with no comparable plan on the destination is not a comparison.
If you already always buy from the same operator (Ubigi, Holafly, Nomad, Saily), MyBestSim is mostly useful to check that no rival offer is ridiculously cheaper. Fine for a scan. Not required as a buying ritual.
