Ratings and reviews

Would not recommend using this service. Credit loaded into the prepaid account just disappeared without any active tariff, customer service was of no help just kept telling me they would forward the issue and I would get my money back but nothing was done.

Cannot login, 1. I am using correct email/number and password and it always says failure happened. 2. Tried resetting password and again same error and app is not letting me login. Same error is happening on website . Can only login in my account with SMS code on website .. but app is unusable.

The App complains about a security risk because it falsly detects my phone as "rooted", which it isn't, but than also restricts the password to 30 characters. A password I had to set on the web site, where I can login just fine. Save your time, just use the website, this so called app is nothing but the scaled down version anyways.
