After a while the traffic was terrible. It was taking 2-3 min to open an address on google maps, not to mention a picture. And a lot of connections issues. Like I said, it worked perfectly at the beginning ### 2/5 — Réseau 3G uniquement ! *2026-08-09, version 5.40.2* Mitigé ! J’ai acheté une eSIM 5G pour l’île Maurice et le plus souvent je n’ai que de la 3G et quelques fois du LTE. Alors que si je prends une eSIM chez un opérateur j’ai la 5G presque tout le temps et partout ### 2/5 — İdare eder *2026-08-04, version 5.40.0* Altay Cumhuriyeti’nde kullanmak için almıştım fakat Onguday bölgesinde ve Novo’da çok iyi çalışmadı. Altay Cumhuriyeti’ne gidecekseniz tavsiye etmem sadece LTE var çok az da 3G var 😕 ### 5/5 — Excelente servicio técnico *2026-08-03, version 5.40.0* Use Yesim para un viaje a Rusia, muy recomendable, tuve un problema y el servicio técnico fue muy atento y paciente conmigo, recomiendo muchísimo Yesim ### 5/5 — Great ESIM *2026-08-02, version 5.40.0* I used Yesim for a 2 month trip in Europe and had connection always, even in more rural areas. It was super easy to set up, affordable, and overall the best eSIM I’ve used. The Europe & UK plan was especially great since I didn’t have to think about getting a different eSIM in each new country. I would highly recommend. ### 5/5 — Вы лучше *2026-07-31, version 5.40.0* Самые лучшие ### 5/5 — For free 5€ *2026-07-30, version 5.40.0* For free 5€ UGBRA887 ### 2/5 — ! *2026-07-28, version 5.40.0* Today only 3G ### 5/5 — Mega top *2026-07-25, version 5.40.0* Super rapide à installer service client rapide comme l éclair même à 5 h du matin .

Appon belül is még vássroltatni akar. Azt kéri válasszam ki hány nap, és vegyem meg a csomagot. Most 20 eurot buktam, mert nem fizetek többet, és net csomagom nincs!!! Csalók! ### 1/5 — Scam *2026-08-07, version 5.40.2* Keep charging me and don’t let me cancel or change payment method ### 1/5 — Impossible à activer utiliser en Chine *2026-08-06, version 5.40.2* • Installation en France compliquée • 2 retraits faits sur mon compte pour le même forfait ! • Prix intéressant 29€ (34€ - 5€ de parrainage) pour 30 jours en Chine • Impossible à activer et utiluser en Chine , 3 jours à essayer en vain et sans internet et surtout sans vpn , toutes les applis américaines ne fonctionnaient pas en wifi , j'ai dû payer une option à 30€ Asie, Chine chez mon opérateur SfR mais toujours sans vpn vu qu'il fallait l'installer avant en France • 1 remboursement de 29€ fait pour non fonctionnement mais le 2e prélèvement, le service me demande une preuve d'achat alors que tout est enregistré et qu'ils ont bien reçu 2 x 29€ depuis mon compte CB visa et le service a clôturé ma demande en 2 jours ! ### 1/5 — Terrible service *2026-07-29, version 5.40.0* Don’t waste your money if you are traveling to Kenya , you won’t have any service ### 1/5 — Connexion qui ne marche pas *2026-07-29, version 5.40.0* J’ai commandé une Esim pour les pays de l’Asie du Sud. Au début de mon séjour elle marchait très bien mais là mon séjour se termine et malgré ma Esim en données illimités celle ci ne fonctionne plus depuis 2-3 jours… Je contacte le service client on me donne des conseils tel que me mette en mode avion etc ce que je fais mais rien ne change. Finalement on me dit qu’ils ne peuvent rien faire car tout dépend de l’internet local dont ils n’ont pas la main 👏 14€ de perdu quand même. ### 1/5 — Soooooo bad *2026-07-28, version 5.40.0* Used for a 1 day lay over in Abu Dhabi was fine Then did travel one for Thailand, didn’t work, they had to reactivate and install.

Avoid at all cost ### 1/5 — No information *2026-07-25, version 5.40.0* I was promised a credit of 5 euros. I cannot find it. I have no purchase history or info on how much data I have left.
