1. Great app!This is hell!!!!! Imagine turning all my contacts to something else all in the name of adding a prefix to my mobile number, now my contacts are invalid, I can't dial a number without removing the unwanted prefixWow Its great, I save half of my numbers with country code and som other without country code! I want to erase country code from my contacts, and it one click done for me.

2. I had an issue with numbers in my Google messages app thinking the phone numbers were from the country I was in when the conversation started, so when moving countries the numbers without the country code showed as the number instead of the name.

3. WhatsApp wanted to test my mental health when I changed number, it changed everything to a wrong country code, this App came to the rescue!This is a very simple ui in a great app.
