Siguro pinakamagandang paraan is to find that sweet spot kung nasaan ka. Depende kasi yan sa cell tower strength sa lugar niyo. Unfortunately dito samin, I get 3 bars stable and pag hinanap ko yung sweet spot, nakaka 4 or full bar ako which is a bit tricky. Globe user ako and malakas dito smart.
If ever, switch to smart siguro kung mahina talaga.
Sana makatulong.
