Don't use your existing mobile # while in Europe and get a prepaid SIM/Phone and mobile # if you don't already have an unlocked phone. I can't comment about which company to use while in Europe. Using your existing mobile # while there will cost you a small fortune.
Is it better to buy and unlocked phone here and get sim card there? DO I need a SIM in each country or is there an international option>?
Should I get phone there ?
What do the SIM cards enable you to do just phone or text data and messaging?
Not to literate in these matters but don't want to return with a huge bill.
I know disabling and using wireless when possible is an option but when it is not I need to have a phone accessible.
any and all advice welcome
