based on my experiance, am sharing this
apart from the configuration of the handset, the following steps are followed by Reliance.
i) MDN is to be mapped to the registered MEID - Automated system does this when no. is transferred to MEID registered handset.
ii) Activation of EVDO on the MDN - If EVDO is not activated on the MDN, eventhough the handset is configured with HDR UN & Password, EVDO will not work. The Request has to be done for actiavation of EVDO with Reliance Customer Care / Reliance World / Reliance Mobile Store. A12Auth Flag checked by the backend.
iii) After this, EVDO starts working, but in case of Handset Change, the process is a bit complex. new HDR UN & Password needs to be mapped manually with the MDN, for this reactivation needs to be done, because when the MDN got transferred to the new handset, everything except mapping of new HDR UN & Password is done by automated process. so , even after transferring the MDN to new device, OLD HDR UN & Password is mapped to the MDN & EVDO will not work on the new device with OLD MDN.
Similarly, if the OLD device is sold to someone, EVDO will not work, evenafter A12Auth is there on the buyers' MDN, because OLD HDR U/N & Password will still mapped with your MDN.
this is purely as per my experiance, as i have gone through all this complex processes for the activation of EVDO on my incredible, because earlier the EVDO was authorized on My OMH RUIM..
Gurus please correct me, if am wrong..
