In what format must phone numbers be written on import?

It is common for companies to collect phone numbers as member data on their members. To import phone numbers into the associated membership card, it is required that the number is written in the correct format and is actually a mobile number. In addition, it is not possible to import home numbers/fixed telephony.

In order for Rule to be able to load mobile numbers smoothly upon importation, the number should be entered in country code format, e.g. +4673867xxx. (46 for Sweden and removing 0)
