AT&T International Day Pass
AT&T charges $10 for each calendar day your phone uses data in Puerto Rico — not each 24-hour window. Arriving after midnight and leaving before midnight the next day costs two full day-pass charges on the same trip.
Verizon TravelPass
Verizon does not require you to enable the $10/day Puerto Rico pass manually. Your phone connects to T-Mobile automatically on landing. The charge appears unless data roaming is switched off before the plane door opens.
T-Mobile Magenta (high-speed add-on)
T-Mobile operates the 5G towers in Puerto Rico. T-Mobile resells access at $15/day. An eSIM accesses T-Mobile directly from $2.71/GB.
Xfinity Mobile International Pass
Xfinity Mobile's day pass in Puerto Rico activates the moment your phone connects to T-Mobile's network abroad — including the two minutes of background data sync when you land. A full $10 charge runs whether you use 10MB or 10GB that day.

Real savings scenarios for Puerto Rico
Solo traveler
A solo business traveler filing a Puerto Rico expense report: AT&T roaming line item is $100 for 10 days. An eSIM line item is $40.65 for the same trip. The company saves $59.35 per employee per trip. Both connect to T-Mobile at 5G. The eSIM receipt shows a single charge; AT&T shows 10 daily charges.
Family trip
A group of six traveling to Puerto Rico on AT&T: $10/day x 6 lines x 10 days = $600 in roaming charges. Six 15GB eSIMs on T-Mobile: $243.90. Group savings: $356.10. That is enough to cover a group dinner for all six travelers in Puerto Rico.
Business trip
Business hotels in Puerto Rico charge $15-25/day for premium WiFi. A 5-day stay: $75-$125 in WiFi fees, covering only the room. Outside the hotel, AT&T charges $10/day. A 13GB eSIM at $35.23 replaces both the hotel WiFi charge and the carrier roaming fee. Data works from the conference hall, the taxi, the restaurant, and the hotel room on T-Mobile's 5G network at one fixed price.
Long-stay and digital nomads
An extended layover (1-2 days) in Puerto Rico: AT&T at $20, eSIM at roughly $8.13. The savings margin is smaller for layovers — $11.87 — but the eSIM still costs less. For a full 14-day trip, the gap opens to $83.09 vs AT&T. For 30 days: $56.10. At no trip length does carrier roaming cost less than an eSIM for Puerto Rico.
Frequent traveler annual savings
Five-year roaming projection for Puerto Rico (2 trips/year): AT&T total: $1000 ($10/day x 10 days x 2 trips x 5 years). eSIM total: $406.50 ($40.65 x 2 trips x 5 years). Five-year savings: $593.50. Both options use T-Mobile's towers the entire time.
Extended stay economics
Most Puerto Rico tourist visas allow 30-90 days. AT&T roaming for the full visa duration: 30 days = $300, 60 days = $600, 90 days = $900. eSIM on T-Mobile: 30 days = $162.60, 60 days = $325.20, 90 days = $487.80. At the 90-day mark, AT&T has cost $412.20 more for identical 5G access on the same T-Mobile towers.
Frequent flyer savings
AT&T roaming of $100 for 10 days in Puerto Rico represents 3-7% of a typical international trip budget ($1,500-$3,000 for flights, hotel, food). An eSIM at $40.65 drops that line item to under 1%. Over 2 annual trips, roaming goes from $200 to $81.30. That $118.70 pays for an extra dinner and museum visit per trip.
Data usage savings
A traveler using Google Maps 3 hours/day in Puerto Rico consumes 24 MB/day in navigation data. Over 10 days: 240 MB (0.2 GB). AT&T charges $10/day regardless of how little data you use. An eSIM at $2.71/GB on T-Mobile charges $0.65 for navigation alone. The eSIM's per-activity cost is a fraction of the per-day fee.
Couples trip savings
The lowest-cost option for couples in Puerto Rico: one 15GB eSIM at $40.65, shared via hotspot. The second phone connects through the first phone's WiFi hotspot. Total cost: $40.65 for both devices over 10 days. Compare: AT&T charges $200 for two lines ($10/day each). Savings: $159.35. Trade-off: the second phone needs to stay within WiFi hotspot range of the first.
UK carrier comparison
Vodafone Roaming Passport charges GBP6/day in Puerto Rico. Over 10 days: GBP60 (approximately $76 USD at current exchange rates). A 15GB eSIM on T-Mobile: $40.65 (USD). Savings in USD terms: roughly $19.35. Both options connect to T-Mobile's 5G towers in Puerto Rico.
Our verdict
Bottom line for Puerto Rico: the eSIM wins. $40.65 for 15GB on T-Mobile vs $100 on AT&T for 10 days. Same towers, same speeds, 59% lower cost. No daily triggers, no per-MB billing, no bill surprises from background app syncs.
