My husband wants me to ask about the "best" SIM card to use with a data plan. We will be in Spain first and then the UK. He has an unlocked iphone7.
I have read the following thread on this topic but there is conflicting information.
Chris F says any SIM card bought within the EU will work throughout the EU, plus Switzerland. Dick in Olympia says the card he bought in Italy did not work in other countries. Plus there was the issue of the prompts not being in English. So i am a bit leery of buying the card in Spain, since (1) it might not work in the UK, where we will need it more, and (b) neither of us speaks more than basic Spanish ( although he speaks good Italian).
I reminded him that when we went to New Zealand he bought a local SIM card and was unhappy with having a different phone number. He says he can live with that, and will tell friends and family to just call my phone instead of his if they need to reach us.
I also asked why he can't just use our ATT account as he has before, with data "off" so we don't get charged. He did have trouble with that when we were in Venice for a month; he learned the hard way that if he turned his phone off ( to save the battery) it would default to data "on" when he turned the phone back on, without any notice ( until the data charge reached $100, at which point ATT sends an alert).
So his main reason for wanting a European SIM card is to get one with a reasonable data plan, so he does not have to worry about inadvertent data use. And so he can use data within a known (and prepaid) limit where we do not have wifi.
Any suggestions? I see Google F1 suggested in the linked thread; would that be a better idea than buying the SIM card in Spain?
Our trip will be three weeks, divided evenly between Spain and England.
Thanks for your help.
