But it is only working with airtel to airtel Volte calls that also only to my friend or sometimes in call for automated reply when someone does not pick up the call

It works when called Jio to Jio. It was showing only HD when called to OnePlus to OnePlus. But when called from OP to my Nokia it shows HD+ and Voice quality is Great.

@RummaanKhan Here jio only HD.And i called to my friend he is using note 9.There it was HD+.

 

[RummaanKhan]

I never saw HD+ on Airtel here maybe it only works in Flagship to Flagship.

Do you guys observed this ? When we compare the rsrp in spreadtrum and a Qualcomm phone a 10dbm lower signal is present in Qualcomm.

@RummaanKhan i have noticed in airtel even if i call to a 2G number.and if the person does not pick up call then HD+ comes for automated reply of airtel.

i did not have speadtrum phone now and when i had karbonn a40 i did not compare but it was very easy to lock LTE bands in spredtrum phone through a ussd code.it was star#star#83781#star#star.No root was needed.even we can see band info,BW etc
