Hey again @jqpabc123. We've heard some banks and fintech firms do that and we can add this feature. For now, popular platforms require only text verification but it'll definitely be in our reminder list. The reason we wanted to test this out is to decide: Whether we should provide a web platform that can help people who need brand-new SIM cards and its capabilities (depending on the needs). And we find it a bit painful to purchase new SIM cards in majority of countries because of the ID and/or in-store purchase requirement. And even if we want to ship a SIM card from no-regulation countries, the cost rises to 10-20X including shipping and taxes. It may even be impossible to ship more than 10 SIM cards due to some country's laws. So, we plan to handle all those things and provide some (or all) features of a SIM + mobile device on our website. Thus, the user can have access to as many brand-new SIM cards/phone numbers as they want. It's also important to note that these AREN'T VOIP phone numbers and also AREN'T provided by Google or Google Voice. That's why, they may have additional functional in terms of testing.
