Hi, yes we feel the problem with SMS and how delivery rate is often not 100%. If I may ask, what do you guys use the SMS for? I'm not too sure how reliable it is during peak traffic, but I think probably best not to use SMS as a single point of failure. And yes SMS in other countries are more expensive and less reliable. In our case, the SMS is not used to login users (we use trusted devices). This should reduce the reliance on SMS - only for verifying that the phone number is active. Our cross-app phone number verification also makes it so that if a user already entered SMS otp in just 1 app, they don't need to enter it again in other apps. Additionally, we're looking to integrate WhatsApp to solve this. About snooping by government officials, I'm not really sure how this applies, but basically since we don't use the SMS OTP for logging in, there is no SMS code to be shared with government officials to allow them to login to someone's account. In our case, the logins would be based off a cryptographic key that is stored in the device's secure storage. As far as I know, this should be pretty safe according to the documentations, that keys cannot be extracted from the hardware. Let me know if I'm not answering your questions :)
