I am able to get my Sprint HTC One to accept my RUIM(CDMA-SIM) of one of the CDMA network provider in my country, by making Sprint HTC One to read from RUIM only. Calls, Text & Data is working. The only issue is that it is continuously staying in 'Digital Roaming' although I've not been charged any roaming charges by my (RUIM)network provider. All the calls, text are being charged normally with absolutely no roaming charges. And another interesting thing is that if I stop roaming by going into Settings-->Mobile Data-->Roaming & selecting 'Home Only', the phone completely stops receiving signal. I don't know why it still needs that Roaming part to be active even though it is not truly in roaming & I was only charged as per normal rates by my (RUIM) Networ provider & again absolutely no roaming charges. And there is no issue with GSM but with CDMA mode you get that 'Digital Roaming'. I hope some one experienced shed some light on this & suggest a solution for this only issue, which although doesn't stop me(us) using RUIM based CDMA Network in my(our) country(ies).
Please take a look at the attached screenshots which prove that data is also working.
