Clarification on Bolt on and O2 Travel

[Sonrob]

Apologies if I seem a little silly, but I have just renewed my package and have been offered some extra's. I have the normal 25GB Fair Use Data included for Eurozone. I am travelling to Turkey soon and, I know this is not covered under the 25GB or calls etc. I have the following extra's I can choose a)O2 international bolt £1 per month and b)O2 Travel which is free. What is the difference between these two if anyone could help me

O2 International is a bolt on which covers calls and text made FROM THE UK ONLY, to countries abroad.

O2 Travel allows you to use your allowances for £6 per when abroad.

Best thing is to use local Wifi.

If contacting people in the UK you can do this over Wifi using Messenger or Whatsapp.(They need to have the same apps installed)
