I've been using this app for almost a year I understand that sometimes the internet connection will not be the best . I travel all around the world because of my job so I use almost every month a different e SIM . I don't plan using this app after my recent experience buying an e SIM at the USA. I brought it but I was never able to activate I spent 1-2 days with the customer support but it was not helpful and at the end nothing happened .

Update: They gave me a refund after I contacted them on WhatsApp and deleted the eSim. I've updated the rating to reflect their good customer service. Too expensive. Download the local telecom providers app and buy their eSim directly though them. I paid $35 for a 30GB sim for the Philippines, but it's routing my internet through Hong Kong which means my AI tools and other services are blocked. I checked the local provider and for $30 I could get 80GB of local service. I feel duped.

Hi! We apologize for the slow speeds in Puerto Vallarta. Since carrier signals vary locally, please turn off 'Automatic Network Selection' in your settings and manually select another network for a better connection. For further assistance, contact us on WhatsApp at +852 9290 0577 with your order number.
