Works excellent and inexpensive global data

I’ve used Yesim during my travels in South Africa and Europe (early 2020). The service works well with newer iPhones and is very inexpensive compared to other eSim providers (paid 6 euro per GB for 30 days). Recommend trying it out to save drastically on your home plans when traveling (often $10 a day with AT&T and Verizon.

Just ensure you do have the right settings: make Yesim your cellular data line and do not allow cellular data switching to your primary provider to save costs.

Not a scam

I was worried that this app was a scam since it’s so much cheaper than the competitors and they have no web presence at all. However, happy to report that it’s working great in Thailand this week.
