Telegram X won’t crack it — it’s official, but it rides the same lanes, no hidden door. Modded builds are worse: they strip the free ones out.
Nothing failed on your end — your code was never sent. Flip the lane instead → No SMS, No Rented Number, No Money — Telegram Still Lets You In · voice · missed-call (the calling number is the code) · email · QR. Free, any country. 
Skip the “free SMS receive” websites too — worse trap, not a shortcut. The inbox is public: your code either never lands (number’s already burned on the same app you’re trying) or lands where anyone can read it — including your account-recovery code, months later, from a total stranger.
