    I have been buying cards in this store, the service attitude is very good, the network of the card is good, the network speed is fast, especially it is affordable, it is much cheaper than my own card, and I have bought more than 100 pieces.

    Easy and very cheap to buy. Much better than anything else I’ve seen.
    Super easy to install on iPhone and very fast response to support questions via WhatsApp (basic stuff because I’m not very IT literate!)
    Used last year in Bali with no issues and now going to Penang.
    Will always use this service for travel sims.

    That was my first time using eSIM for traveling. Easy to apply and install to my iPhone 12 mini. Fast 5G network support during my Germany trip. Also, there is a good price in the unlimited roaming plan. I definitely will use it again!
