Can anyone help with the following please, I really should know this
but this is how I think it works.
0044 and +44 are the same thing?
All based on using UK sims
Scenario one
Two people with UK sims, phone each other when outside of the UK = The first 0 is dropped from each others number and either +44 or 0044 added?
Scenario two
Someone phones from the UK on landline or mobile phone to a UK mobile which is abroad, no change needed to the mobile phone number but adding 0044 or +44 would not do any harm?
Scenario three
Phoning a mobile in the UK from a mobile abroad = remove the first 0 and add either 0044 or +44?
Scenario four
Phoning a landline in the UK from a mobile abroad = remove the first 0 and add either 0044 or +44?
