Quick verdict on MyBestSim
MyBestSim presents itself as 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. The site is not a shop: like most directories, it sends you to the operator checkout. Affiliation is the model. That is not a flaw. It becomes one if volume, or a promo banner, replaces the explanation.
If you search “MyBestSim review”, the question is not “is it a scam”. It is a discovery tool. The useful question, on 28 August 2026, is: does this list help you pick a plan, or does it make you hesitate longer?
- 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 Comparator: same fields (price, GB, validity, 5G, hotspot), then pay at the operator.
What it is and how it works
Typical path: you enter a destination, MyBestSim shows 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 Comparator cover the same need, with a deduplicated catalog.
MyBestSim does not sell the eSIM. Listings, sometimes promo codes, sometimes reviews, are the product. 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.
A “5 GB / 7 days” plan is not the same object if it is a named local operator, an MVNO, or a regional pack with fair use. MyBestSim shows offers. It does not always translate between those offers.
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 you get very cheap entry packs, often short or thin on GB. Sort by data and week-long packs drown under long or unlimited plans with fair use.
A global brand review says nothing about your week in Osaka. Cross-check a country page and, if you can, the local network name.
A promo code only exists if it still works at checkout today, and if the operator is actually listed on that destination. On eSIM Comparator, catalog promo codes are checked 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.
