What advantages do Collectible Numbers have over SIM cards?

Firstly, you receive a Telegram authorisation code on the Fragment platform, bypassing the cellular network. Accordingly, a text message containing the authorisation code cannot be intercepted by attackers over the cellular network. Blockchain is much more secure in this case.

Secondly, SIM cards can be reissued by the perpetrators with prior collusion. And you can lose not only the number but all accounts that are tied to it! Collectible Numbers are NFTs, they cannot be reissued. The owner of the NFT is the owner of the "Swiss Safe". The seed phrase from your wallet is the key to your "Swiss Lock".

Thirdly, in the privacy settings, you can make this number visible to everyone. This is very useful for channel owners, moderators and advertisers. Often scammers pretend to be other people by copying the name and username (changing 1-2 characters) of the former. Also, they can mimic the owner's number, finding a similar one. For example, +44 20 7559 6412 is similar to +45 20 7559 6412. The +888 numbers are almost impossible to spoof because there are no similar mobile operators in the world! Attackers will not be able to fake your account, which shows the unique Collectible Number.

Fourthly, in many countries, you have to provide an ID to buy a SIM card, in the case of Collectible Numbers, you don't have to do that.

Fifthly, you need to replenish your SIM card regularly to keep it alive. Also, many SIM cards are usually blocked after a year without any replenishments. In the case of Collectible Numbers, this risk is excluded, as they remain on your wallet (e.g. Tonkeeper) forever, do not require replenishment and there is no risk of blocking them.

Sixthly, you remain completely private. Collectible Numbers are not linked to a physical SIM card, so it is not possible to triangulate your location. For additional security, you can change your linked Collectible Number regularly.
