customer support is zero and I don't recommend anyone to buy sim form here

Worst sim provider, my data didn’t work and no support from their tech team. Avoid at all cost.

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. Valery
