I am Not recieving sms code by verification on my Nokia 8110 with KaiOS when I try to login to Telegram. It had happen many times before. This little and simple OS is like a toy and I do not know if the security level is the best. But is possible to receive a validation on mail instead or other way around as I can not contribute to the chatroom otherwise then.
This forum is for /e/OS not KaiOS. Pl check on the KaiOS forums for guidance.
Since KaiOS isn’t even Android one would be hard-pressed to offer simple tips/checks such as proper permissions settings and whatnot. You’re on a whole different platform and need to redirect your queries to applicable forums.
