The Fone&Text app requires a technically correct phone number in Daylite to work correctly. This means international phone numbers require the country code, area code and the telephone number. A national phone number requires at least the phone number and in addition to that the area code if you are calling from outside this area. Spaces or dashes to separate country code, area code and phone number are perfectly fine and can be used without causing problems.
Please find some examples below.
National telephone number (area code + phone number)
International telephone number (country code + area code + phone number)
+49 2622 9780000
0049 2622 9780000
