I have used "Pay as go" so far in UK.
So on 3rd every month, I topped up 10 pounds for activating "Pay as go"
Now I am considering traveling abroad, Austria, 4th to 15th in July.
I know that I can use "Travel Abroad" option with 1.99 pounds per day.
My question is that is it okay to top up 10 pounds after coming back from Austria even though every 3rd each month, I had to top up 10 pounds for "Pay as go" option so far?
I am worried about that my phone would stop working when I arrive in Austria if I don't top up on next 3rd as I did before.
