Slickcall Customer Insights

1. I have to keep repeating calls because the lines cut too often.THERE'S TOO MUCH STATIC, FADINDG IN AND OUT, VOICE NOT HEARD, CALLS DISCONNECTED, SOMETIMES THE CONNECTION DOESN'T LINK...ALSO, I SENT SOMEONE $5 TO USE FOR CALLS, THEY DIDN'T EVER RECEIVE IT, THEY WERE UNABLE TO MAKE CALLS! ON THE UPSIDE, YOU CAN MAKE CALLS, THEY DO GO THROUGH MUCH OF THE TIMEFor 3 days usage, the quality of call is audible,the persons I call hear me well.I will continue with Slickcall.Calling price is reasonable.

2. Keep it up.I can'take call to Kenya every time I try toake a call it tells me it needs permission to make calls ...so frustrating and annoying, can't recommend anyone to this app.very simple to use, and there is no need to dial multiple access numbers to call international numbers.Today i subscribed in the Slickcallapp and bought a plan for a month.

3. The very boring and annoying app I've seen, had I known and stayed on "Rebtel" than this Nuisance!! Can't disconnect calls I have to go plane mode or switch of wifi, My QUESTION TO THE DEVELOPER IS "DO I Just HAVE TO LOOK AS THE CALL CONTINUES YET WE'VE ALREADY SAID BYE??" And I have no right after topping up? Sending money delays to up-to 7mins and now One can't disconnect Calls???.

4. You can only remove recent but not call transactions or entire calls why.

5. However, the customer service of slick app is so good, that they gave all the efforts and after couple of hours, i could finally make a call and got connected with my family and friends in Germany.

6. If these are not explained well and about the privacy of our calls not monitored and other things i mentioned i wll opt outPoor connectivity.

7. IDK 🤷 ♂️Is like a deceitful app, at first you made sound like $1 for 60 minutes and credited the account with the same amount, thereafter $1 is not an option on the app, but $5 the least, and the same $5 went down the drain within 60 minutes, check my account and proof me wrong.

8. It begin to look to me like a scam.Pls this app has no options to delete the entire call history or transactions why.

9. I hope no body is bugging this calls.

10. First time I thought it was my phone... but now I'm trying on a different phoneToday is my first day using the app.

11. Calls hung up abruptly.
