Enabling peer-to-peer authentication between at least two mobile devices associated with one or more wireless telecommunication networks

A non-transitory, computer-readable storage medium comprising instructions recorded thereon, wherein the instructions when executed by at least one data processor of a system, cause the system to:

• receive, by a first wireless telecommunication network, a request to authenticate an international mobile subscriber identity (IMSI) from a first UE;
• determine, from the IMSI, an identity of a second wireless telecommunication network;
• determine, from the IMSI, a unique identifier associated with a second UE;
• request, from the second wireless telecommunication network, a confirmation that the unique identifier associated with the second UE is a member of the second wireless telecommunication network;
• and
• upon receiving the confirmation from the second wireless telecommunication network, send the confirmation to the first UE that the IMSI is valid.

A method comprising:

• receiving, by a first wireless telecommunication network, a request to authenticate an international mobile subscriber identity (IMSI) from a first UE;
• determining, from the IMSI, an identity of a second wireless telecommunication network;
• determining, from the IMSI, a unique identifier associated with a second UE;
• requesting, from the second wireless telecommunication network, a confirmation that the unique identifier associated with the second UE is a member of the second wireless telecommunication network;
• and
• upon receiving the confirmation from the second wireless telecommunication network, sending the confirmation to the first UE that the IMSI is valid.
