4/5Can anyone misuse my cell number?
Why it is so easy to log in? I logged in by my specific cell number and verified, and i tried my other phone with the same verified number! And surprisingly it logged in! How it could be? Then anyone who knows my cell number can misuse the credits of my account! Any good answer?

5/5Got to speak to a special loved one.
This app is really good for speaking to loved ones across the world. And because of Telz, I was able to speak with a loved one after one year of not speaking with each other. I’m so happy!! The connection is amazing for far off countries, you can record phone calls, and the price is good as well.

5/5Grateful
Thank goodness for this international calling app. My mum only has a landline and does own a smart phone or any electronic device, so FaceTiming and iMessage is not an option to stay connected. This app makes it extremely affordable to call her landline overseas and the sound connection is brilliant. Very happy user. Thank you.

5/5Great service
I absolutely adore this app! It’s the best out there. Their service is top-notch, and I’m always happy to recommend it to my friends.

1/5Bypass this application
I have added funds just for this application not to make phone calls. I won’t even connect a call but takes your balance. Horrible application and customer service has not reached out to my request for help. I lost my $10, but they won’t steal a single penny. I would advise people to use other apps.
