Still looking

Try this service http://smspva.com/, I have used them for a long time and the prices are lower than what you are asking, you need to pay $ 1 + fees and you will be able to activate several times.
Currently, you need to pay about $ 0.1 to activate Telegram.
I am not sure if Telegram supports VOIP numbers activation.

If you do not want OTA (one-time activation,) you can rent some numbers.
