In late 2022, Telegram released a limited run of virtual phone numbers as collectibles on the TON blockchain. Telegram users can use these NFT numbers to sign up without a SIM card and receive their login codes directly on Fragment, rather than via SMS.
All anonymous NFT telegram numbers start with the prefix +888.
If the number is open to everyone in the profile, then the number can also be used for a link instead of a username. For example +88808888880

Keeping track of the implementation history +888 numbers:
For a limited time, there were only 2 options for buying numbers:

Option 1:
Buy immediately (without auction) long 11-digits a random number of the type 
+888 0*** **** 
The buyer did not know which number he would get, he saw it only after payment. The price was 9 ton from December 6 to December 12. From December 13 to December 24, the price began to increase by 1 ton every 3 hours until it reached the price of 99 ton. After reaching 99 ton, the possibility of mining random numbers disappeared.
P.S. Most of all the routine numbers +888 are occupied by random numbers, they account for more than 90% of the total number of existing numbers.
P.S. At the time of writing this text, the price of random numbers on the secondary market has been hovering around $ 1,000 for several months.

Option 2:
Put up for auction a short 7-digit number of the form:
+888 8 *** (the initial price of the first bid was 1000 ton)
or put up for auction a long 11-digit number of the form:
+888 2222 **** (the initial price of the first bid was 175 ton)
+888 1111 **** (the initial price of the first bid was 175 ton)
+888 0*** **** ( the initial price of the first bid was 20 ton)
The auction lasted from 7 to 14 days. 

For the entire limited period (approximately 3 weeks) The following numbers were crunched:
+888 8 *** - 357 numbers out of 1,000 possible.
+888 2222 **** - 26 numbers out of 10,000 possible.
+888 1111 **** - 27 numbers out of 10,000 possible.
+888 0*** **** - 136,156 numbers out of 10,000,000 possible.

The most expensive was the ULTRA VIP number +888 8 888 with a final bid of 300,000 ton.
P.S. Everything is simple here:  The number contains only 1 digit + this digit repeats the digits of the prefix +888. But that's not all, in many cultures of the world, the number 8 is the most desired digit, meaning infinity, wealth and prosperity. All this gives such a high price during the initial mint and the number +888 8 888 can truly be considered the TOP1 number in the ULTRA VIP category.
