Major Airtel 4G issue: No internet while on voice call

[sudipt123]

Just a passing thought, how do apps like truecaller work on Airtel 4G in that situation, as the caller-id feature uses the data packets in parallel when the call comes. can someone who's on airtel 4g confirm this?

If the fallback is 3g , you have 3g data and voice at the same time.

evn i am not AIRTEL 4G,
Issue i am facing is that when i am on 4g network(4g preferred) and if some one calls they gets busy tone.

If this is true- it's a serious flaw. Just reminded me of the limitaion of the 2g dual SIM phone- where you had to divert the voice calls to your other number. Pathetic i would say. Was on the fence to move to Airtel 4g but after this discussion, am contemplation to stay with RCOM

Best is to use dual sim fone, one on 4g other on 2g.

truecaller just dont work in such situation.
I am using cdma smartphone (in cdma also data do not work while on call or even when call is ringing), and truecaller do not show the unlnown caller name.
when i disconnect the phone it latch data and then true caller show the name.

@amitnsonu Thanks for the clarification, does this happen on EVDO as well?

@chromaniac in 2g edge, the data connection will be put on hold when voice call is active [ditto for evdo, even though that's like 3g version of CDMA]. So when fallback on 2g, no internet. But in Delhi Airtel has got 3g, right?

You can enjoy both voice and data when fallback on 3g. Tested with my k3 note yesterday on Chennai

Yes this happed in both 1X and EVDO because both work on same frequency.

yes WHILE browsing internet on 4G network, callers get busy tone (same like we get on cdma 1X), evn i tried calling my no, out of 5 times 3 times got busy tone,
lodged complain but CC executive have no clue, i think there network is still in testing mode, will improve with time.

Does switching to LTE+WCDMA only mode in phone Field test help? In that case the phone will fall back to 3G mode during a call
