Aggiungi # per prefissare il numero di telefono e salvare come numero di telefono secondario in contatto
Add # to prefix phone number and save as secondary phone number in contact.
For example:
Contact abc has one number only 088 088 0888
Using your app, you can create a second number for the same contact but prefixing it with a #. Then Contact Abc has 2 numbers 088 088 0888 and #088 088 0888
