I am using a dual sim smartphone with sim cards on both the slots. Sim card inserted in slot 1 receives 3G data but, the other sim card inserted in slot 2 receives only 2G data, even though 3G internet pack is activated.
I swapped the sim cards between the slots, believing that there might be an issue with the mobile network, but the same problem exists.
- My smartphone: Moto E 2nd Generation 3G
- Android version: 5.0.2
I have even changed the preferred network type to 3G for the sim in slot 2 (Settings -> Data Usage -> Mobile network settings ->Preferred network type) but, no change.
What could be the issue ?
