Welcome to the community. 🙂
As @Chris_B said f you're on an EE pay monthly Max plan (after 10 May 2017), you will be able to use your allowances while travelling in Mexico at no extra cost.
Otherwise, take a look at the page that he referred to for the roam further add-on or the roaming tool for other add-ons and prices.
Please text ROAMING to 150 to make sure your phone is set up for roaming before you travel.
