Looking for apps to back up contacts and messages on iPhone 6
My phone has a problem of continuous restarting. I took it to the apple shop and they advised and insisted to reset it completely and start it as new phone. I did but now I can't see like 200 of my contacts, in addition I will loose all of my messages. I am going to restore my phone and backup my contact and messages using a third party app and then start it as new.
Question: Can you please let me know which one of apps (for iPhone, either free or paid) on app store are best ones for backing up and restoring messages AND contacts?
Thanks a lot
