Really depends which countries you want to charge. If it's worldwide - there are some problems, if it's eg the EU, far more possible, if it's the US, it's too tightly governed by FCC rules. US used to be virgin territory and excellent earner - but that stopped, mainly due to scammers/fraudsters - but not before we pulled $12 mill in 9 months, - pity idiots messed it up tho.

You are correct re the phone billing descriptor - in the US it would say "Premium Services" and there is a limitation (tho need to check this) on how much can actually be charged under FCC rules.
