DISQUS

Eric: the roaming revenue does not go to your native home operator, approximately 80% of it is retained by the foreign operator. Overcharging foreigners is a premuim segment for telecom operators worldwide.

And SIM card is not a disc, it is a chip. Its most important function is to identify user in GSM networks - it exchanges codes with the operator's IT core system that allows to uniquely identify the handset user. It is very secure.

Yuri, my understanding is that a nicely profitable chunk of international roaming rates does go to a US users' home carrier.

I carelessly used the term disk. I've fixed.

I have owned a United Mobile (formerly known as Global Riiing)sim for many years and never had any problems. I used their customer service once (in English, but they are obviously multilingual) and found them to be more than competent. I am about to purchase another Sim for a fmily member in fact. The best part is free incoming calls in Europe. We pair it with a cheap int'l long distance plan in the US and talk for hours. One correction, the cheapest sim card is 29 EUROS and the price in dollars is $39.90.
