We tried two different eSIM options – both worked perfectly: we had a number, received text messages, and had good speeds. After connecting to a local network, we had to reset our data for the eSIM to work.★

Easy to set up, stable signal, good price. I highly recommend an e-SIM for all travelers. We bought my husband a SIM card on site (his phone doesn't support e-SIM) for four times the price.★

1.5 GB for 15 days, eSIM used in Phuket. The connection is excellent everywhere, both at sea and on the islands. I used no more than 500 MB per day. I was satisfied with both the price and the quality.
