Pros

“Routine tasks — sending a multi-page fax, copying a configuration — turn into multi-hour or multi-day ordeals. If your workflow depends on faxing or on managing your own phone configuration, look elsewhere before you commit.”

Owner

“I explained that I was sold the account with the understanding that all 5 of my phone numbers could use SMS at the same time.”

Bob W.

“The ability to call customers from the app where my personal cell phone number will not show up.”

Amy L.

Bob W.

owner

“Literally 20+ emails to close my account and they still charged my credit.card the momth after i closed my account.”

Jason S.

“However, despite this, Nextiva continued charging our credit card for five additional months, without our authorization.”

Joseph S.

Cons

“Integration requires careful setup and even small configuration mistakes can prevent calls from syncing correctly across devices.”

Suhaad H.

“I imagine how difficult to deal with them; moreover, if you have a business number that your clients used to contact you on, Zadarma can cancel it at any time and ruin your business !!!”
