I need a US telegram account.
If you're thinking of buying an account then Visit the marketplace board and use any of the goods sub-board like
Digital goods but be careful of scammer and only trade with those with green (positive tag or neutral) never trade with those in red tag.
About the DM; have you tried using the telegram spam bot to identify the reason you can't PM those not in your contact first sometimes could be because of your DM were reported to be spam.
