Before I used the onsimcard abroad, it was hard to tell teh difference between my ordinary cell phone and onesim card phone. when I stayed domestic, onesim card is expensive, so there is little advantage, however, when I traveled Peru, I compared the price, and recognized that the price is one tenth and even less.
I intalled onsim voip on another phone with a US PEN. When I was at a hotel and used wi-fi, I could use onesim and the rate was one hundreds. And when I was in outside the hotel, I used onesim direct, so I could be connected to voic network continuously. The connectivity was a great advantage.
But I did not use onesim data. It is very expensive. so, onesim card phoe is good especially for international voice roaming.
