From my understanding, you won’t have data until your call is completed. Your Verizon voice still uses data. Can’t have two different data SIM’s running at the same time.
I am using Verizon for voice and AT&T for data. When I’m on the phone, I do not have data. I have cellular data switching on, so I’m supposed to have data. Anyone have this problem?
The cellular data switching is switching your data for verizon when you are on a call. This is because the phone only has one radio so during a phone call the data provider has to be the one with the active call. Since Verizon doesn’t support data while on a call, you are losing data during calls.
If you had Verizon for data and AT&T for calls, then it would work. When you take a call on the AT&T line the cellular data will switch to AT&T and you would be able to use it while on the phone.
