Scamish
Not a scam but they try to get you to buy account packages in $25.00 increments which is non-refundable should you not use it. And then they remove money each month from your account for the unused balance. I paid $25.00 one month. Used about $10.00. Few months later went online to get another SIM and saw my balance was less than a dollar. When I messaged I was told it was because I wasn't using the money in the account. I was told I could just buy the time I need outright but that is very obscured on the website and doing so requires an advanced turn-on date. The service providers they use seem to be the cheap carriers of the respective areas. I would not use them

Good day. I paid on 12/17/2024 for 4 SIM cards for Europe, 3 for 10 GB and one for 5 GB. I did not receive the SIM cards. These are scammers.
