OK, I'm sure there are loads of information about this on the forum but I'm a real novice and really can't understand all the technical gobbledygook that's written in most of the posts so please can somebody give me advice in non-technical terms. My wife and I are soon to take off to Europe and will want to use our phones whilst there, a few phone calls, WhatsApp, and use of various apps, Search for Sites, LPG locator, maps mainly, we won't be watching films but would like to pick up emails. We're with EE who charge £2 a day each to use whilst we're away, 5/6 weeks so will be an expensive extra. I've read about buying SIMs but if we do this I take it we will lose our current phone numbers. If a free roaming charge SIM is the answer, any suggestions? Finally, is it really as simple as taking the current SIMs out and putting the new ones in? I would much appreciate any help and advice that you can give me. Thanks
