Anyone tried using OneSimCard IoT Starter Kit

I am looking at the OneSimCard IoT Starter Kit and was wondering if anyone has used them in the past. Their website for IoT SIM Cards is iot.onesimcard.com and it looks like they have been around for a long time.

Hello,

We would not have information regarding who has used these before.

We have a lot of visitors on this page. I am sure someone will have some type of input on this for you.
