Blynk Getting disconnect from server when Call Number

Need Help With My Project
,
1

Use titygo module i.e. Esp32+7600G module;
Blynk heartbeat is set to 60, and the gsm rx buffer is 1024.
I connected to Blynk using the Gsm network and it sent the senors value to the server using the timer function properly and a good network connection but when I do call the number, it disconnects from the Blynk server and I get a message like connecting to Blynk server and retrying… So what’s the issue is that… Is the 7600G can handle multiple concurrent connections… or is it code fault…
Thanx : )

This Kind of Blynk Log After the call it disconnects. I think it’s due to sim7600 not handling concurrent connections or May be due to the switch of the band from the internet to call the band. I handle this using Blynk disconnect then after call connect but still sometimes it does not work…

Also is there a way to connect Blynk to LTE as I see in debug it connects to GPRS

[66942] Modem init...
[67031] Connecting to network...
[67061] Network: Home

[68749] Ready (ping: 310ms).

This Problem I solved this Using the different SimCard that supports IoT devices.
When we do call the modem changes the network GPRS to calling network band and hence after the call hangup it doesn’t switch fast so it won’t connect but in IoT sims, this will happen fast and get connected.
Also, some Sims don’t like this way of switching the network and hence it may take time. .
This is based on my experience.
