EU may end all roaming charges

[inquisitor]

You are right. The EU plans indeed consider smaller operators who cannot offer Europe-wide single tariffs due to their limited geographical footprint. But as you and VladS have suggested above it has to be feared that the market for alternative roaming providers may suffer from discrimnation by the large multinational operators and that it may not be able to compete as long as it remains an alliance of regional underdogs.
