4.5 out of 5
Do not use

What app hides your card information from you? Trying to delete my credit card information from Slick but cannot find it. My bank text it is going to be a reoccurring payment! How? Why? I did not sign up for auto pay and you automatically put me on auto pay. Trying to switch but I cannot!!! Be careful where you put your card information. Your money is gonna be deducted without your authorization after the first payment

Worst app on the market !!!

Slick was OK when I first started using it . But for the last couple weeks every time I have purchased a calling plan , as soon as I purchased a plan it blocks me. I can’t use the plan. Can’t make phone calls can’t send tip ups , nothing ! And I can’t get a hold of Support. So while my loved one is waiting for me to call and expecting me to call , I’m messaging Support over and over. Nobody’s manning the phones. as I said before, this has happened to me two other times in the past couple weeks and the last time it happened, I was assured that it would never happen again, which was of course a lie because I decided to give them another chance and use Slick and it blocked me again as soon as I purchased a plan. And you can’t get nobody to answer the phone. I have been messaging them on WhatsApp, which is where they told me for urgent matters to message them. And I have been messaging them for several hours now with no response and no return messages!

Poor customer service

After purchasing call credit for $5 on June 30th, 2022, Slickcall took advantage of the fact that my credit card details was in their system, and went ahead to charge my account for another $5 on July 1st, 2022, without my authorization or approval. I have initiated action to have my card reissued by my credit card company, since blocking their access to my card on file will not be possible. Subscribers are advised to always check their account. I am beginning to feel that Slickcall may be involved in some fraudulent practice. Hardly does anyone answer the contact number, instead they call you at their own time. The lady at Slickcall that I complained to promised to call me back, but never did.

What is slicall offering that other apps are not?

I got a text saying call only for 20/min in Ethiopia when in fact I can call 19/min using Boss-revolution and other apps. There are $1 bonus when you also charge your balance on Saturdays in other apps. However sicall is saying only one time $1😂

Perhaps what turned me away the most is the requirement of my email in addition to my phone number. What about my social security number then?😂 you know people are afraid of giving every information this days and I did not have to give my email to other calling apps and they are cheaper as well. So why should I give more information to Silcall and also pay more ? Help me understand this🤔

Calls and credit

Slick is slowly becoming useless. It has been about a year since I started using it and now I put credit in there but I can barely make any calls. Calls get connected but I never get to hear anything. If I use my sim card to call, its loud and clear. Above all, my credit is getting wasted for nothing. Sometimes it just ends calls or starts repeating conversations like no ma’s business. And the credit is getting used up. I am considering getting another option. And honestly I am not sure if i can recommend this to my friends who needs something like this.

Poor

It was soo good at first I thought I got a solution for my international calls . Now the past month or so it has been pure hectic . I’ll make a call too much static and it keeps taking the money . I contacted the customer support with took over 2 weeks to finally refund me 3$ and told me the issue was taken care of . I called and vuala it worked . Poor me loaded 5$ again thinking it’s back to normal and now it’s not even ringing . I have been calling and all I get is disconnected . I tried different numbers and it’s all the same . Am not loading up credit after this ,am done with it .

Thought was a solution but quite the opposite!

Customer service is almost non-existent. Too much chaos with Slick , 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 …. Slick is promising but as is for me right now it feels like a beta version … this app Call needs to improve functionality of Slick.

Expensive in Ethiopia

It’s too expensive and I don’t recommend! There’s a subscription plan but to expensive when you compare with the Boss Revolution, it’s a big difference the only advantage is it stays for a month but how could I talk only 80 minutes in one month which is funny 😫80 minutes talk is only for a night 🙁

Poor customer service

I bought call credit for a plan but it didn’t go through. I called customer service who said he would set a call appointment for me with the manager at my request. He never set the appointment and never got back to me. I contacted them through their WhatsApp and they never responded. I’m done with them!!

Pricy!

There are few things I like especially when it comes to the way it counts the minute. It shows ringing and not minute counting until the conversation actually begins. That is the feature that made me abandon my Boss Revolution app that I’ve been using for years. I switched to it and never looked back since. The price per minute was okay but suddenly I noticed it jumped about four cent more than it competitors. Now it may not look a lot but when you’re doing INTERNATIONAL calls every penny counts. I have not been observing the price but when I saw that it did not sit well with me. I do a lot of international calls and I’m always going to look for the cheaper option. At least with my precious app it never still charge me u til the conversation began, I just could not tell when the minute counting began because it starts right away. But yeah it Didi not like that price jump.

MISSING CRUCIAL FEATURE

They need to have a feature where i can just auto-send money to a certain contact especially parents on a personal preference set sequence because sometimes we’re too busy we forget our parents so this feature will be very helpful and i’ve been waiting for this to happen please

Getting connected

What a feeling of relief to be able to hear the person you are calling so clearly you understand every word being said. way more of a higher quality sound.

Wonderful Quality When I Call Nigeria!

This is such a great option and so much more affordable than other networks! We can conversate longer and with more quality than all of the others. Thank God for such a wonderful platform!

Very clear calls, quick connection

I am quite amazed at how quickly the call was connected, and the quality of the call was great. There was no interference no loss of volume or crackling during the call. Excellent.

Slick Forever ❤️✈️

This is incredible! In fact, all my friends will hear about it today! Extremely cost effective and very stable network communication! Thumbs up for this provider 👍👍👍🎊🍾

If possible, I would really like to partner with you!

Clear call

Slick is easy to download, the calls are so clear and the most interesting part is the contacts on your phone, you just scroll to the person you want to call.

Great connection

I didn’t realize it wasn’t a local call because we were completely clear and no sound or echo noted. Hopefully you keep the same vibe and it’s going to be fun catching up with family and friends

Best app

I was just trying the quality of the call and I am surprised that the person on the other side was as if he was next door. Very clear and sharp. This will be my go to app whenever I call internationally. Bravo!

Slickcall calls

This is my first time to use Slick. The call was clear without noise. It is also cost saving: one dollar goes along way. If this is maintained, then this is one of the best apps to use to call internationally. Am very impressed

No conference calls

It would be nice if you made it possible for more than two people to talk at the same time. You don’t have that feature to add people to the conversation
