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.

In principle fine, you don't need to use it very often, but I'm disappointed with the last changes and the backoffice systems. Upgrading to a more expensive data connection was fast, but downgrading again: Now I'm charged for two different data contracts on the same phone making it twice as expensive, and I only followed the instructions. And yes I checked the validity period. First I was charged for new package and then old was extended instead of replaced at end of validity period
