Questions and answers
Does Three charge for roaming in Europe?
Yes, unless your plan includes it. The current Three price list has paid options for Europe, shown in the table with source and date.
Can I use a travel eSIM with my Three number?
Yes. Keep your Three SIM for calls and texts and use the travel eSIM for data. Your phone needs to support eSIM and be unlocked.
Do I pay Three anything when I use a travel eSIM?
Not for data, as long as data roaming is off on your Three line. Calls and texts on your Three number are charged as in its price list.
What if I forget to turn off roaming on Three?
Then your Three SIM can use data abroad at the Three rates for that destination. Turn off data roaming for that line before you land.
