Three U.K. has today announced that customers will now be able to use their U.K. allowances of calls, texts, and data in the United States and three other countries at no additional cost as part of its “fear-free” Feel At Home roaming initiative.

EE launched the United Kingdom’s first 4G LTE network back in October 2012, and with it came some pretty expensive price plans; the carrier has certainly been taking advantage of the fact that it has the U.K.’s only 4G network. But that approach is going to be spoiled by rival carrier Three.

Already the cheapest of all the U.K.’s major providers, Three is looking to maintain its position by promising its customers that they won’t pay any extra for 4G connectivity.
