NO INCOMING CALLS while surfing

[Afrasiab]

Hi everyone,

I just got my new HTC Evo 4g from USA. In Uzbekistan, no mobile operator provides 4g. However, the phone has worked with one operator. But I got a huge problem here, my phone seems to be not able to receive calls while I am surging on the internet, as soos as I turn off mobile internet, it seems to be working fine.

I have read a few topics related this, my DDTM mode is "Uncheck", so is there any way to fix it ?

Thanks in advance and sorry for my bad English

If u leave that DDTM mode checked it will not interupt u while on data and send any incoming call directly to voicemail. If unchecked it should interupt ur browser and make u handle the call. If ur not getting calls sounds like the network ur on. Also if u bought the phone here on the US, the network here is CDMA, voice and data can not be used at the same time. This is why people get global phones CDMA/GSM. GSM is what ATT uses for IPhones, which is why those users can do both V and D simultaneously. Hope this helps
