Based on our stats from Flurry for our Prague iPhone app, over 80% of the users of the app in the Czech Republic are on the O2 (formerly Eurotel) network. It's a well-known fact that O2 has the lion's share of business and high-income customers in the Czech Republic, but I was surprised by these numbers. Here's the breakdown for our Prague app:
| Carrier | Percentage of requests |
| O2 (Eurotel) | 82.7% |
| T-Mobile | 13.2% |
| Vodafone | 4.1% |
Of course, these numbers only represent what we are able to measure. That said, the Nelso Prague app is installed on over 5,000 Czech iPhones, so this is a pretty good sample.
