Why should I use DataESIM in Puerto Rico if my existing US carrier (AT&T, T-Mobile, Verizon) already provides service there?

While your US domestic plan theoretically extends to Puerto Rico, relying on it often means being deprioritized on partner networks, leading to inconsistent speeds (frequently 3G or throttled LTE) and coverage gaps. DataESIM, conversely, establishes a direct, high-priority connection with Tier-1 local networks, such as T-Mobile Puerto Rico or AT&T (Liberty PR). This ensures you consistently access the fastest available 5G/LTE speeds, critical for remote work, large file transfers, and uninterrupted video conferencing, bypassing typical roaming limitations.
