Why was the RAEX format implemented?
MNOs, MVNOs and Hub Providers are sharing the IR.21/IR.85s information with each other to ensure that all roaming services work for the inbound roamers, guaranteeing the best customer experience for the HPMN and to assure all the roaming revenues are captured on both sides. Sending the documents in an electronic format (XML) makes it much easier for the VPMN to process the data and it ensures the HPMN’s submitted data is crystal clear – unlike free text information that is either unclear or might get ignored/overlooked by the VPMN.
For this reason, the RAEX IR.21 standard was implemented in 2010 and has been further improved ever since. Since 2020 also other players like MVNOs can create, distribute, and receive the files via the tool by becoming a Rapporteur Member of the GSMA. By now 704 operators have already published their IR.21s via the tool, so the percentage of operators being compliant with the standard is very high.
