A competitively priced eSIM that does the job.

Ubigi eSIM. I am always a little cautious when using a new eSIM that I’v not tried before. Would it live up to the promise? I have to say so far so good. Excellent connection in Switzerland with good data download on my iPhone 15. The Ubigi app works well and it shows the rate of data usage. The price is good and very competitive. Very happy to recommend
