Too much chaos with the App, my calls only last ~2.5 min before somehow disconnects but still keeps on counting minutes. On one occasion I topped $10 only to disappear had to call for it to reappear after more than a month. Tried to reach out to them about the 2.5 min calls via WhatsApp and calling to no avail. Just being honest here …. The App is promising but as is for me right now it feels like a beta version … Slick Call needs to improve functionality of this app. ### 1/5 — CALLS *2026-02-19, version 2.4.20* It’s unfortunate that I can’t make a call and if I try call call customer service it can get through ### 1/5 — Used to work well *2026-02-19, version 2.4.20* It’s just a frustration with endless popup offers that are usually expired when you tap on them. But even the call function now works less than half the time! I’m trying to find another service! ### 1/5 — Payment services *2026-01-28, version 2.4.20* To change a payment card should not be an inquiry procedure where I must proof my details first before allowed to be given the option to change. This have always been a self service issue especially when the card expired. Fix this ASAP or loss customers ### 1/5 — Scammers *2026-01-27, version 2.4.20* This app is a scam. Failed connections then credit disappears within 24 Hours. Awful App! ### 1/5 — Fraudulent welcome offer *2026-01-14, version 2.4.19* The welcome offer £0.99 never went through, the calls kept going to voicemail until 30mins rounded up. ### 1/5 — Scammers….Run *2026-01-03, version 2.4.17* That’s all I can say ### 1/5 — Do not buy this plan *2025-12-21, version 2.4.17* Do not waist your money ### 1/5 — Scammers *2025-12-05, version 2.4.17* You can make a purchase then it doesn’t immediately show thinking it didn’t go through. Slick hide transactions so that you can double purchase unintentionally. Sometimes they automatically withdraw money without consumer awareness. I won’t recommend this app minutes goes by soo fast ### 1/5 — Not stable *2025-12-01, version 2.4.17* Not stable. Even unable to login because the login sms cannot be received. ### 1/5 — Poor *2025-10-11, version 2.4.16* Is it just me or had the app been down for others in the last 48hrs? ### 1/5 — Too Expensive *2025-09-15, version 2.4.12* I have been a long time user of this app. I specifically call to Kenya and have always bought monthly bundles. This has now been scrapped and we are stuck with $2 for a day and unlimited $5 for a day. I’m going to delete and move to another app. Shame on the developers. ### 1/5 — Deceptive *2025-09-03, version 2.4.12* I never write reviews but this app was so frustrating to use! I made a 2$ purchase and yes transaction went through because I checked my bank account but the money was gone. I exited the app and entered a few minutes later and my balnce went back to 0.00. I didnt even make a call! It’s not about the $2 spent but how this app swallowed up my money. How can you trust to continue using the app? ## Most critical reviews (10 lowest-rated) ### 1/5 — DM /Redsea one inc *2026-07-25, version 2.4.31* I have used the application for quite while but this days very strange things happen the welcome offer the just pup up to the screen but if you need to cancel it doesn’t go away this must be address complaint guidelines for the store so what are you wait Apple QA team do this is embarrassing the Apple company ### 1/5 — Poor *2026-07-05, version 2.4.31* Every call placed drops in seconds , you can’t make any effective call without interruption ### 1/5 — Customer service *2026-06-09, version 2.4.31* Horrible company.

Poor customer service, frustrating service, lots of try and let’s see. Better get out of here to save time and money. ### 1/5 — Fake fake *2026-03-15, version 2.4.22* Don’t not use this Slickcall. After a few weeks, you can’t make calls with your credit. When you call them, they will send you a link to delete app and download again but it doesn’t work. Don’t patronize them ### 1/5 — Nunca la e podido utilizar bien *2026-03-13, version 2.4.22* El problema q cada vez q utilizo esta aplicación para conectarme con mi familia no me sale y para cobrarme el dinero es rápido , es mala esta aplicación ### 1/5 — Very bad app and customer services *2026-03-10, version 2.4.22* I don’t recommend this app to anyone very bad customer services and the app is very bad it keep disconnecting ### 1/5 — Worst app ever *2026-02-24, version 2.4.20* I'm really frustrated with the service. I bought credit to call globally, but it never showed up on my account. When I tried to call, it said I had a zero balance. I reached out to support, and they told me to wait 24-48 hours, but my credit expires in 12 hours! I asked for a refund, but they said no. Super disappointed with this app, wouldn't recommend it." 😤 ### 1/5 — Not good *2026-02-24, version 2.4.20* This app was great at first but right now is just worse, customer service is not good, they don’t rectify issues. I wouldn’t recommend this app at the moment unless there is a positive change, but at the moment I’m done with this app ## Most praised reviews (10 highest-rated) ### 5/5 — Eng. *2026-06-25, version 2.4.31* Reliable ### 5/5 — Cheap Call Rate *2026-02-27, version 2.4.20* Rate is cheaper than other call apps ### 5/5 — Great job *2026-01-25, version 2.4.20* Wawa helpful ### 5/5 — Nigeria calls *2025-09-01, version 2.4.12* Excellent for Nigeria calls. ### 5/5 — Skype replacement👍🏻👍🏻 *2025-07-25, version 2.4.11* When Skype got shut down by stupid Microsoft I didn’t know what to do, since I used it allot to call overseas.
