Will be purchasing Orange Holiday Zen 8GB eSims for my spouse and my own unlocked cellphone for our upcoming two weeks in the UK which will come with French phone numbers. Had good experience with them in December while traveling through France and Belgium.
To phone cell numbers in UK with our phones, do we need o dial +44, or 00 44, or 0 44 before phone number?
To call each others cell phones, do we need to dial +33, etc.?
