Yesim’s eSIM and cellular data reviews

I have used Yesim during my travels in South Africa and Europe (early 2020). The service works well with new iPhones and is very cheap compared to other eSim providers (I paid €6 per GB for 30 days). I recommend trying it to save drastically on home plans when traveling (often $10/day with AT&T and Verizon.


Just make sure you have the right configuration: make Yesim your mobile data line and don’t allow switching mobile data to your main provider to save costs.


I was worried that this app was a scam, as it is much cheaper than competing apps and they have no web presence at all. However, I am happy to report that it is doing very well in Thailand this week.


Easy to use and does what it’s under for! Not many ads, if any. Thank you. This is the only app that works for me.
