Our t-mobile phone plans include low-data-rate service in Europe. It is handy to have phone service right away. It is not handy to have a LOW data rate but it works for email and basic stuff. So we always get a Spanish SIM with a high data rate. We have always used Vodafone although it has issues and we think we might switch each year but but we haven’t yet. So that is an errand for the first day. Charlie switched his phone to an eSIM so he has both services. Wynette brings a back-up phone which holds the t-mobile SIM.
For some reason the prepaid plans do not include texting but we can still text on t-mobile. But just about everyone in Spain uses WhatsApp so we normally use that.
Wow! So high tech… eSim, WhatsApp (maybe not so high tech). We just stick with our T-Mobile good coverage, but low speed data rate, but count on the wifi at hotels (and presumably in bars [pubs when we are in Britain]).
