MyBestSim (mybestsim.com) positions itself as an independent comparison site: 100,000+ plans, 200 destinations, tested providers, data / duration / price filters, and exclusive promo codes. On listing pages, though, several operators tied to those codes do not appear. Curation saves time; the promo / table gap is awkward.
MyBestSim: promo codes on show, operators often missing from listings
The shortlist helps. The promo-code / listing gap matters more: a code without the operator in the table does not help you choose. A rushed traveler gains comfort, not always the best €/GB. eSIM Giga currently compares about 271,326 priced plans from 63 providers across 252 destinations, ranked by total price and €/GB.

OVERVIEW
How MyBestSim works
MyBestSim is not a carrier. You compare published plans, then pay at the provider. As with us, the eSIM is access to a host network.
The site says it does not list every market offer. Selection leans on service quality, price clarity and reviews: the opposite of eSIMDB. The weak spot is consistency: codes are pushed while the matching brands are missing from listing pages.
At eSIM Giga we normalise total price, €/GB, validity, hotspot and network. MyBestSim is another door, not a replacement for that grid.

TEST
Filters and result quality
MyBestSim filters follow the site model. Always re-read validity, usable volume and terms before you pay.
Visible levers. You mostly filter destination, volume and price. €/GB is not always first.
Still a list. After filtering you still read terms. Not a single verdict.
Checkout at the provider. The comparison site does not carry the network. Check the host at purchase.
Public figures. Figures here come from public pages. They move. Cross-check.
STRENGTHS
What MyBestSim does well
Clear entry. MyBestSim gives a destination-to-offer path without requiring a power user.
Independent listing. Not a single-brand shop.
Own angle. Curation + codes, incomplete listings.
Possible complement. Useful as a second look beside eSIM Giga, not instead of it.
WEAKNESSES
Real limits of MyBestSim
MyBestSim does not replace a €/GB ranking and terms on a destination page.
Codes without operators in the listing. MyBestSim pushes exclusive promo codes, but the related operators do not always show in destination tables. An orphan code is not a comparison.
Less published method. Fewer explicit rules than our methodology.
Shortlist or noise. Either too few brands or too many similar rows.
Promo vs value. A sticker price or code is not usable GB cost.
Not a carrier. Support and activation stay with the provider.

DEDICATED GUIDE
Compare MyBestSim alternatives
Table, use cases, limits: the detail is on the dedicated page.
Yes as an independent comparison site. It is not a carrier. You buy at the provider. Public figures (100,000+ plans / 15+ curated providers / 200 destinations) still need checkout checks.
Do MyBestSim promo codes match the listings?
Not always. Exclusive codes are pushed, but the related operators are often missing from listing pages. A code without a row in the table is not a usable comparison.
Is MyBestSim the best eSIM comparison tool?
No. MyBestSim has a useful angle (Curation + codes, incomplete listings). eSIM Giga leads for ranking a destination by €/GB.
