Most modern phones will know when you are roaming outside your home location and when calling or texting numbers you have stored in your contacts, will automatically use the correct international calling prefix to call the number from the country you are in
However not all phones will do this, so you should try calling or texting the number manually by replacing the initial 0 in the number with 0044
So UK number 07123 xxxxxxx should be dialed as 0044 7123 xxxxxx
