I have recieved continuous numerous spam calls, from around the country, on a DAILY basis. It's sickening. This app has continually blocked these numbers. There are too many to count to report these numbers to the FCC. Return calls, from a different phone, only result in robo calls & messages. I have referred this app to my friends/colleagues. Keep up the good work.

A really great app. I got the app from a message T-Mobile sent me and I downloaded this. I get less scan calls now. Of course I still get a few, but nothing is perfect right? It’s a nice add-on to my current T-Mobile network. It blocked some of my friends, but I can just favorite them and they don’t get blocked. I love the fact T-Mobile sent me a message saying, “Download Scam shield from T-Mobile.” We did not have to wait and randomly find it. Overall great scam killer. Be fore the calls got annoying. So I got an annoying voicemail greeting. Blocked real people but not scam bots. My missed calls feed got spammed with calls. This app changed all that. Much less scam calls. Just so you know, THIS IS A SERVICE OFFERED BY T-MOBILE. ITS MOST LIKELY NOT GOING TO BE PERFECT. Thanks for reading this long review

About a year ago my number got sold to some companies that would call me 3-6 times a day. I just put up with sending them to voicemail because I didn’t want to have to change my number. I switched to T-mobile, got premium Scam Blocker and this was one of the first things I set up. It took 2 days for it to learn which calls to block and it’s been wonderful. The peace of not getting woken up at 7 am on my day off due to a scam call, and not having random numbers blowing up my phone is worth a lot more than I thought.

Update: As of July 6, 2021 the app is doing what it's supposed to. No crashing or freezing as of late. Thank you. This app lessens the headaches from any unwanted call. Thank you. _________ This app used to be great, but as of late it's crashing and freezing a lot. Is this app considerate of my time.... Not anymore. It does a great job of blocking numbers. It would be totally cool if this app could block those annoying 4 digit scam numbers. Is the app easy to use..... Yes, when it's working.

I like the app it does what it says. It can be a little frustrating because it will also block numbers that are in my contacts or are not spam numbers. There are times that previously blocked spam calls come thru not sure why that happens or it misses some spam calls. I would like them to upgrade the app so that you have an option to block spam text messages. The spammers are aware that people can block their calls so now they are reverting to texts, please help with this.

Lots of talk about being able to block calls but the BLOCK feature seems to not work occasionally. You can select BLOCK on a number and the block button will light up; however, when you return to the number in the ACTIVITY list, the number you just blocked is unblocked again. Therefore, the 4-star rating I am giving applies to the app when it is working properly. This situation has happened several times over the period year-long period I’ve used the app so the failure is temporary. When the failure situation is happening - like it is at the time of this writing - this app deserves maybe 2 stars. The reason I’ll give it two stars is because it still blocks known or suspected scammer numbers that are preemptively blocked by the app. If the app already knows them, they get blocked...but those only amount to about 20 percent of the scammer calls I receive.

It's a good app--It does block unwanted and unknown calls, but I'm finding that it has a tendency to block a lot of calls from numbers that are essentially good, but only come up as the number (for example, a business calling me about an order ready to be picked up got blocked). The default operation of the app is very black or white--you're either known and allowed through, or unknown and blocked. You can change that after the fact by going in to the logs and either starring (allow) or have it sent to voicemail the *next* time the number calls, but with no information about the caller given, there's no good way to figure out if that was a call you wanted to get, or a truly scam call to block. My biggest peeve, though, is that there's no option to set the default operation for unknown/possible scam calls to be 'send to voicemail,' that way you can figure out who was on the other end of the line and whether or not you should pick up the next time, or even return the call. I've dug through the app options and haven't found that yet, so I'm hoping it could be put in one of the next updates.

Great start for giving consumers control over there phone calls however i think you can do even more. I would like to have this expanded to text messages as well. Also I would like to have it where the system can identify where the call originated from or where the call is regastered to like where the person lives. Also add a report option to report that the a call was categorized incorrectly or the caller id info is wrong. This way theses issues are fixed and new calls made by that phone number would show up correctly to other users. Also add a option to record phone calls for calls that come in that are not on my contacts list. This way if a call is spam legal authorities would have something to use agenst thesss people to put a stop to unwanted calls. Needs to be expanded to include text messages as well

For the most part this app is awesome, that is if the number actually comes up as spam. But I continually everyday receive these darn robo calls. There's no ID information on the caller. As someone that pays for this premium feature, why are all these calls coming through? I mean if there's no available caller ID information I would assume that it is a spam call - block it! But something else I find could use some improvement is not all my calls show up right away. Which makes it tough to block.

Selecting activities I get a list of all incoming calls that come from my phone’s recent calls. I have blocked and marked all that were spam calls yet the all incoming calls feature shows some of the numbers I’ve labeled as spam in red with blocked indicator. It also shows spam calls that I have labeled spam and have them blocked it shows those numbers in black without the blocked indicator. Also under manage this is where you have the ability to add numbers to either a favorite, block or send to voice mail. Somehow a number on my block list showed up under favorites and there is no way to delete it. Now it’s no big deal except how do I get rid of it if it’s no longer a favorite and the issue if I should add a number to the block list and then later change my mind. In short the app needs some fine tuning.

Seems to work fairly well. Less calls are definitely getting through. I do wish there was a way to report as 'not a scam'. It flagged one of my contacts and sent them straight to voicemail. I'm hoping that future calls from that person will get through and not be permanently pushed to voicemail now. Kind of frustrating.

Had to delete app as it no longer worked. It required that my WiFi be turned off and have at least 2 bars. That doesn’t work well when you don’t have sufficient coverage/service (usually 1 bar both at home and work which are 45 miles apart) and depend on a wifi connection to another internet provider to be able to use your phone. I’ve reached out several times inquiring on when T-Mobile was going to improve their service strength was keep getting told it has been upgraded and should see considerable improvement by month end. That was in June 2019, November 2019, and last was July 2020, I gave up since it appears to have been false information.
