The last of the big four UK carriers to announce its 5G plans has now done so. O2 5G service has officially launched today, though with the same extremely limited coverage seen on other networks…

The company says that no premium will be charged for 4G access.

The company says 5G service will initially be available in six cities, and the usual caveat of course applies: You’ll only see it in a few isolated locations for now.

All of O2’s plans come with “unlimited” phone calls and texts. O2 5G prices depend only on the amount of data you want, starting at £25/month for 5 GB to £40/month for “unlimited.” In all cases, “unlimited” means for personal use only and subject to an unspecified “fair usage” clause.

The CEO of parent company Telefónica, Mark Evans, described the launch as a significant one.

I believe 5G is going to revolutionize the way people and businesses use mobile connectivity, unlocking huge possibilities for our economy and society. No one in the country has all the answers today, but I’m excited about getting it into the hands of our customers and working with leading partners to help shape the future of 5G for the next generation.
