They reel you in with good promotional offers and bite like a shark afterward. They have responsive WhatsApp support but have inflexible data plans. On the brighter side of things, they're a bona fide service provider with good internet speeds if you have good network reception.

Rubbish Connection & Terrible Customer Service I bought a 20GB eSIM for my trip to Istanbul. It worked for just 3 hours after landing, then stopped working the next morning. I wasted 6 hours at the hotel trying to get help, with customer service taking 15–30 minutes to reply to each message. The same problem happened again the following day, and I eventually gave up. Terrible connection, painfully slow support, and a complete waste of my holiday time and money. I would not recommend it.

I used it in Uzbekistan; the internet didn't work in some places, but overall it did the job. The reason I gave it one star is because after returning to Türkiye, the system automatically activated the "Pay as you Go" option and deducted $3.90 from my balance. Apparently, the "Pay as you Go" option is enabled by default and needs to be disabled in the settings. If you forget to disable, the system deducts your entire balance. contacted WhatsApp Support, but they did not refund the fee
