1/21/22 At first it was working great, but now having major issues. It won't send messages. Sometimes I will receive the text message. I will have to use another app. Update 6/8/22 I thought it would get better with all the complaints on the same issues. No it didn't get better only worst. Text messages won't come thru on time, but the spam callers don't miss a beat even with the spam blocker on. I would not recommend this app.

I works, but JUST works. Caller ID works 15% of the time (callers from my phone book). If I have a notification and tap it, I still have to refresh my text feed to see the new call/text. Often times I have to close out the app and all background apps and try again. It does work great for my "office" number for my business so I'm not inundated with calls on my personal line. App and operation Could be better, for sure. Also when traveling out of the country, didn't work AT ALL.

When you stop subscribing, you lose access to all of your text messages. In addition, there is no group texting, there are significant outages, texts are not searchable, and texts for identify verification often do not arrive in time. But losing access to my messages after I needed to upgrade is the reason that prompted this review. There was no warning that this would happen, and I lost essential information for my business and created a really embarrassing situation with a client.
