Q: My 5s won't backup to ICloud but my IPad will

I have done that. I purchased more storage on 5-8 and have 7.8 GB available. My IPad backed up on 5-13, but my iPhone will not even do a "back up now".  It just keeps "thinking" and never advances. Thank you, though, for the advice. Any other thought?  I called Support yesterday and they mentioned something about my settings but then told me they could help me if I paid $140 for the annual technical support because my complimentary support had expired. I told them, no thanks.

Thank you, but it does not have the message I receive when I try to back up. The message is, "the last backup could not be completed"

I tried backing up again, and I received the message, "verification failed". Any suggestions?

Thank you. I tried this and it still would not backup. Thanks for the suggestion.
