However my phone's both SIMs(SIM1-Airtel& SIM2-JIO) having full network(4G) while traveling in train not able to use as well as download any content from any platform. It's always getting buffered during the Era of 4G n 5G.
I was using JIO SIM in slot 1 of my Samsung M31 phone. Recently I have brought one more 4g SIM of punjab airtel which is working in slot 2 of the same device but it doesn't work in slot 1 of same device after changing and resetting of network setting...
