Restricted account for no reason

Save your time and money - don’t use this app!!! Restricted my account I was using for business because of zero reason and support said they can’t help. Horrible company
JTara LLCJTara LLC

Has big flaws

Two biggest flaws: #1. You can’t save names of contacts in the app only. #2. When someone’s calls me, my phone doesn’t ring no matter what settings I set. I only see missed calls and have to call them back. When I do, the app uses a stranger number to make the call.

Doesn’t let me make my account so what’s the point

Error creating account

I can't even create an account. I get a 8293 error.

TOTAL FAIL FOR THIS APP!

Restricted my service without knowing why

I had sent my wife several text to see how my signature came out and was automatically blocked and their support team said they don’t know the reason why and couldn’t restore my service. Ridiculous
