Real savings scenarios for Mayotte
Solo traveler
A solo business traveler filing a Mayotte expense report: AT&T roaming line item is $100 for 10 days. An eSIM line item is $31.52 for the same trip. The company saves $68.48 per employee per trip. Both connect to Orange YT at 5G. The eSIM receipt shows a single charge; AT&T shows 10 daily charges.
Family trip
A group of six traveling to Mayotte on AT&T: $10/day x 6 lines x 10 days = $600 in roaming charges. Six 20GB eSIMs on Orange YT: $189.12. Group savings: $410.88. That is enough to cover a group dinner for all six travelers in Mayotte.
Business trip
Business hotels in Mayotte 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 20GB eSIM at $31.52 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 Orange YT's 5G network at one fixed price.
Long-stay and digital nomads
An extended layover (1-2 days) in Mayotte: AT&T at $20, eSIM at roughly $4.74. The savings margin is smaller for layovers — $15.26 — but the eSIM still costs less. For a full 14-day trip, the gap opens to $106.82 vs AT&T. For 30 days: $157.80. At no trip length does carrier roaming cost less than an eSIM for Mayotte.
Frequent traveler annual savings
If Mayotte is one stop on a multi-destination travel year: AT&T charges $10/day in every country. eSIM prices vary by destination. For Mayotte alone: $100 (AT&T) vs $31.52 (eSIM) per 10-day trip. Across 4 international trips averaging 10 days each, AT&T charges $400 in roaming alone. eSIMs for the same itineraries run 80-95% less per trip.
Extended stay economics
Most Mayotte 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 Orange YT: 30 days = $94.80, 60 days = $189.60, 90 days = $284.40. At the 90-day mark, AT&T has cost $615.60 more for identical 5G access on the same Orange YT towers.
Frequent flyer savings
Business travelers averaging 4 international trips per year: 4 trips to Mayotte at 10 days each = 40 days of roaming. AT&T: $400/year. Four eSIMs: $126.08/year. Annual savings: $273.92 per employee. A company with 10 traveling employees saves $2739.20/year.
Data usage savings
A traveler using Google Maps 3 hours/day in Mayotte 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 $1.58/GB on Orange YT charges $0.38 for navigation alone. The eSIM's per-activity cost is a fraction of the per-day fee.
Couples trip savings
When a couple splits up during the day in Mayotte (one at a museum, one at a market), each phone needs its own data connection for maps and messaging. Hotspot sharing fails when partners are apart. Two individual 20GB eSIMs at $31.52 each: $63.04 total. AT&T for two lines: $200. Independent eSIMs save $136.96 while providing separate data for separate activities.
UK carrier comparison
UK travelers face lower daily roaming rates than US travelers: Vodafone GBP6/day vs AT&T $10/day in Mayotte. But the eSIM still costs less than both. Vodafone 10-day total: GBP60. AT&T 10-day total: $100. eSIM: $31.52. The eSIM wins regardless of which home country the traveler comes from.

- How much does carrier roaming cost in Mayotte?
- Verizon TravelPass and AT&T International Day Pass both bill $10/day in Mayotte. T-Mobile offers free international data, but caps speed at 256 Kbps — unusable for navigation or video. Pay-per-use rates without a plan can exceed $2,000/GB on AT&T. An eSIM on Orange YT starts at $3.99 for 1GB, delivering full 5G speeds on the same local towers your carrier roams through.
- Is T-Mobile's free international data fast enough in Mayotte?
- No. T-Mobile's free tier: 256 Kbps. Google Maps minimum: 500 Kbps. Video calls: 2,000 Kbps. Streaming: 1,500 Kbps. The free tier covers text-only WhatsApp and nothing else in Mayotte.

- How is my roaming bill calculated in Mayotte?

Model 2: per-MB (AT&T $2.05/MB without a pass, $2,099/GB). Model 3: flat-rate eSIM at 1GB for $3.99 — one payment, fixed cost, no daily or per-MB charges. Model 3 is the only one where a background app sync costs nothing extra.
- Can I keep my phone number while using an eSIM in Mayotte?
- Yes. Your home SIM keeps your number active for calls and texts — enable WiFi Calling so those work over hotel WiFi. The eSIM handles all mobile data on Orange YT's 5G network at $1.58/GB. Both SIMs run simultaneously. iMessage and WhatsApp stay tied to your home number because they identify you by phone number, not by which SIM provides the data connection.
- Does turning off roaming affect text messages in Mayotte?
- No. Incoming SMS arrives with data roaming off — texts travel on the voice network, not the data network. Disable data roaming only, not the SIM itself. Your home SIM stays active for calls and texts while the eSIM on Orange YT handles data at $1.58/GB. This setup costs nothing on your carrier bill — only the eSIM plan fee.
