Updating contact information using SMS after a number change

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

• receive, at a contact update server of a telecommunications network, from a unified data management (UDM), an indication of a telephone number change associated with an account in the telecommunications network;
• retrieve, by the contact update server, contact information associated with the account from a virtual storage space of the telecommunications network, wherein the contact information includes multiple contacts of the account, and wherein each contact is associated with an identifier;
• generate, by the contact update server, a set of short messaging service (SMS) messages to each of the multiple contacts based on the associated identifiers,
• wherein the SMS messages include information related to the telephone number change;
• transfer, by the contact update server, the set of SMS messages to a short message service center (SMSC) of the telecommunications network;
• and
• deliver the SMS messages to each of the multiple contacts of the account via the SMSC.

A system comprising:

• at least one hardware processor;
• and
• at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:
• receive, at a contact update server of a telecommunications network, from a unified data management (UDM), an indication of a telephone number change associated with an account in the telecommunications network;
• retrieve, by the contact update server, contact information associated with the account from a virtual storage space of the telecommunications network,
• wherein the contact information includes multiple contacts of the account, and
• wherein each contact is associated with an identifier;
• generate, by the contact update server, a set of short messaging service (SMS) messages to each of the multiple contacts based on the associated identifiers,
• wherein the SMS messages include information related to the telephone number change;
• transfer, by the contact update server, the set of SMS messages to a short message service center (SMSC) of the telecommunications network;
