When you’re travelling, losing voice signals is a given. Continuously moving makes it harder for the signals to reach you. If you’re roaming, you’re under another carrier’s tower. They can weaken the network of users with another carrier which causes call dropping. In case it’s raining, you cannot expect much signal strength. Water blocks the radio signals from the cell tower to your device antenna. But, you don’t have to worry since there is a solution to everything. Try these methods and see if they work out for you!
