Free phone number abroad

Hi,
The only grip I have is if I need to use a free phone number from abroad, eg 0800… I can not call from abroad.. Sometimes I need access to these numbers when traveling in Europe..

Did you put +44800 when calling

Yes.. I needed to ring +44800 and 0333 (+44). I called the Lebara help centre and was told when i am abroad in Spain 0800 numbers are treated like premium numbers 🤷🏻♂️

Looking it this further it looks like most networks work like this as the person you are calling on 0800 pays for call so they block calls from outside UK.
Same with o2 and other providers.

My wife is on 02 and her phone works fine from abroad to fee phone numbers … Maybe your network has a different policy..
