AT&T's US customers visiting the UK should benefit from a new 4G roaming arrangement with the EE.
The agreement should mean that visiting Americans who are AT&T customers can use their own phones and SIM cards to in theory (due to spectrum differences) access average speeds of between 24Mbps and 30Mbps on EE's network, which will cover 160 towns and cities by Christmas.
The AT&T deal is EE's first 4G roaming agreement, and the operator expects to ink similar deals in early 2014.
EE said that its UK customers should gain access to 4G networks when travelling abroad by the first half of next year; however, a spokesperson for the company declined to provide details of which countries will be included to ZDNet.
Also not mentioned is whether US customers will need to pay additional fees to use EE's network. If the deal is similar to one AT&T announced earlier this month for US customers travelling to Canada, there will be additional fees when roaming, meaning the main advantage for subscribers is that they'll be able to keep on using their own phones, typically on-contract with locked SIMs, while travelling.
AT&T's deal with Canada's Rogers Communications offers US travellers access to the operator's Canadian LTE network, which covers 70 percent of the country's population. But to access the network, customers still need to buy one of AT&T's Data Global Add-On packages, which cost $30 for 120MB a month, $60 for 300MB a month, or $120 for 800MB a month, and are available for over 150 countries. Verizon charges similar prices data roaming for non-LTE data access in over 200 countries.
Verizon is expected to announce similar roaming arrangements next year, ZDNet's sister site CNET reported earlier this year.
The deal comes as Europe attempts tofor customers travelling in other EU countries.
