We tested both networks across Jakarta, Surabaya, Bandung, and rural Central Java over 30 days. Coverage maps rarely tell the real story. Our field data reveals which operator truly dominates Indonesia's most densely populated island.

Singapore set itself an ambitious target to achieve 5G coverage across half the island by 2022 and nationwide by 2025. We examine where coverage actually stands today, which operators lead on speed, and what standalone 5G means for consumers.
